    • AkzoNobel Industrial Chemicals, Rotterdam // Netherlands

      • Safe treatment of wastewater for the Botlek Chemical Park

        AkzoNobel Industrial Chemicals b.v., which is based in Amersfoort, produces salt and energy, chlor-alkali products and derivates. It is Europe's largest producer of vacuum salt and a leading supplier of chlorine, caustic lye, hydrochloric acid, ferric chloride and chemicals for processing water. The products have many areas of application and are used by, among others, the detergent, construction, food, paper, aviation, automobile, pharmaceutical, textile and plastics industries.

        The project

        The composition of the wastewater generated by AkzoNobel's chemical park at Rotterdam Harbour is highly complex due to the production of chlor-alkali products, vinyl chlorides and herbicides at the different business locations on the site. Faced with the prospect of further production challenges in the future and the need for sustainable, state-of-the-art wastewater treatment processes, AkzoNobel decided to look for a competent and expert partner to extend and then manage the facilities on a long-term basis.

        The procedure

        By implementing an optimization concept, drawn up to fulfil AkzoNobel's individual requirements, the performance of the two-stage facility (chemical/physical precipitation phase and biological treatment) has been able to be increased. Furthermore, the way wastewater is accepted has become more flexible, the amount of chemicals used has been reduced and less sludge is generated. By implementing REMONDIS' accredited plant operations concept, AkzoNobel now also has access to the company's know-how gained from running numerous industrial wastewater treatment facilities.

        The benefits

        • Increased performance
        • Greater flexibility
        • Greatest possible levels of availability
        • Reduction in the amount of chemicals used

      Volkswagen India, Pune // India

      • Ideal wastewater management for the automotive industry

        The Volkswagen plant in Pune is one of the largest investment projects by a German company in India. It is the only German production facility that encompasses the entire manufacturing chain – including the press shop, body shop and paint shop and the final assembly. In total, the plant fills an area of 2.3 million square metres, employs 3,500 people and has a capacity of 200,000 vehicles per year.

        The project

        REMONDIS Aqua is responsible for the wastewater treatment at Volkswagen's production facilities in Pune. Within the framework of a BOOT model, REMONDIS Aqua initially built, operated and maintained the facilities between 2012 and 2017. After completion of the BOOT period, the contract was redesigned and REMONDIS continued to be responsible for the operation and maintenance until 2021.

        The procedure

        Two of the plants each clean 500 cubic metres of the highly contaminated wastewater per day from the paint shop, sewage and other production using a biological wastewater treatment process with subsequent membrane bio-reactor (MBR). A third plant cleans another 500 cubic metres, also biologically, in a sequential batch reactor (SBR). The treated wastewater can finally be used for irrigation purposes. The sewage sludge produced in the purification process is dewatered, dried and used as manure. 

        The benefits

        • Safe wastewater treatment through modern technologies
        • Compliance with environmental standards and water protection
        • Planning, construction and operation from a single provider
        • Resource conservation through recycled water

      The food processing industry at the fishing port in Bremerhaven // Germany

      • Different types of wastewater. One facility

        Wastewater from the food processing industry is primarily contaminated with organic and biological matter. It undergoes the best possible treatment at the Bremerhaven site.

        The project

        We have been operating a number of different facilities in Bremerhaven together with the city authorities since 2003. These include the central sewage treatment plant which treats both municipal sewage and wastewater generated by the food processing industry located in the fishing port.

        The procedure

        The fully biological sewage treatment plant is equipped with state-of-the-art technology. REMONDIS Aqua uses a multi-stage treatment procedure at the plant. The sludge generated by this process is recycled in a modern biogas facility and used to generate energy.

        The benefits

        • Highly efficient
        • Eco-friendly method used to generate energy

      Trespa International, Weert // Netherlands

      • Reliable treatment of highly contaminated wastewater streams

        Trespa International B. V. develops ideas in the area of architectural materials and is a leading international producer of high quality panels for exterior cladding, decorative façades and interior surfaces.

        The project

        Trespa® Meteon® is Trespa's leading family of architectural panels. These are decorative high-pressure compact laminate (HPL) with an integral surface manufactured using Trespa's unique in-house technologies: Dry-Forming (DF) and Electron Beam Curing (EBC). Trespa supplies over a million such panels to its customers all around the world every year.

        The procedure

        Having carried out some successful trials, REMONDIS Aqua built and now operates an aerobic activated sludge facility with "cross-flow" membranes (MBR facility) to treat the company's production wastewater. The particular challenge here is that the wastewater contains high concentrations of formaldehyde and phenol. The wastewater facility contains extended pre-filtration and sludge thickening technology.

        The benefits

        • 99% of the waste load is biodegraded in the supply line
        • The solid material and biomass are completely separated; no solid substances in the discharge water
        • Wood chippings from the pre-treatment phase are re-used

      Ruhr-Zink, Datteln // Germany

      • Removing heavy metals safely without the need for lime

        Ruhr-Zink GmbH is part of the GEA Group and manufactured zinc and sulphuric acid until 2009. The company has devoted itself to recycling: using a zinc electrolysis procedure, it has processed the largest proportion of secondary input substances from the steel industry than any other business in the world.

        The project

        REMONDIS Aqua built a wastewater treatment plant at Ruhr-Zink in Datteln back in 1999 that meets all requirements for comprehensively cleaning wastewater strongly contaminated by heavy metals. As the general contractor, we took on the entire management of the project – from drawing up the concept, to financing the project, to ultimately putting the plant into operation. Since then, REMONDIS Aqua has been responsible for the smooth operation of the plant using its own staff and has clearly met the treatment targets at all times.

        The procedure

        In the past, Ruhr-Zink used to treat contaminated wastewater with lime in accordance with conventional treatment procedures. This led to large quantities of gypsum waste being generated which was contaminated with heavy metals and which had to be disposed of despite the costly subsequent treatment. Thanks to the special wastewater management and treatment process developed by REMONDIS Aqua, this volume of residual waste has been reduced by 90%. The different kinds of wastewater are first collected separately and later brought together deliberately to make optimum use of their neutralisation potential – without the addition of lime.

        The benefits

        • Gypsum waste contaminated with heavy metals is no longer produced
        • Lower waste management costs
        • Optimised processes
        • Eco-friendly solution

      Oettinger Brewery, Mönchengladbach // Germany

      • Building and operating a wastewater pre-treatment facility with energy recovery

        For over 10 years now, the Oettinger Brewery in Mönchengladbach has been producing a large part of the group's wide range of products. Every year, it makes up to 2.3m hectolitres of drinks.

        The project

        Looking at its output figures, Oettinger Brauerei GmbH is Germany's biggest beer brand. The company produces and sells a wide range of beers and soft drinks. With the business continuing to grow and wishing to implement more environmentally friendly processes, it decided to have a new resource-friendly concept drawn up for its wastewater treatment processes.

        The procedure

        Whilst drawing up the new wastewater treatment concept, priority was put on achieving greater efficiency and process stability combined with greater cost effectiveness. The company opted for REMONDIS Aqua's high-tech process – its RE2ENERGY® process – in which the contents in the wastewater are transformed into biogas in a fully automated anaerobic pre-treatment facility.

        For the most part, the procedure involves anaerobic wastewater treatment. Once the solid matter has been removed and the water neutralised, the wastewater undergoes anaerobic treatment in the RE2ENERGY reactor which not only cleans it but also produces biogas. This pre-treated wastewater can then be discharged into the City of Mönchengladbach's sewer system. The biogas is used straight away in the production plant. The plant needs hot water to manufacture its drinks which had previously been produced in a boiler using natural gas. Once the boiler had been upgraded with an additional biogas firing system, the biogas was able to be recycled and used here leading to a reduction in the amount of natural gas consumed by the plant.

        The benefits

        • Little space is needed thanks to the best possible use of technology
        • Sustainable wastewater treatment with the generation of carbon-neutral energy
        • The primary fuels, previously used to generate steam for the production processes, have been substituted

Oerlemans Foods exports to more than 50 countries in Europe, the Middle and Far East as well as South and North America.

        The procedure

        The wastewater at Oerlemans' two production plants in the Netherlands is treated using an aerobic activated sludge facility with immersed membranes (MBR facility). Both the quantities of incoming wastewater and the substances in the water differ due to the various products that our customer processes throughout the year. Concentrated waste and sludge are collected and then used externally to produce biogas. A completely new facility was built in Broekhuizenvorst; the existing SBR facility in Waalwijk was converted and upgraded. Both facilities are equipped with pre-filtration, intermediate storage and sludge thickening technology.

        The benefits

        • Reliable and stable wastewater treatment process
        • 99% of the waste load is biodegraded in the supply line
        • Fully automated; it is possible to monitor the whole process externally

        The project

        H.Borgmeier GmbH & Co. KG was founded by Heinrich Borgmeier back in 1903. Over the years, the company has enjoyed steady growth which meant that it needed a new wastewater treatment concept for its production facilities. At the beginning of the project, the system was expected to treat 400m³ of wastewater per day; the wastewater treatment facility is now able to treat a daily volume of 600m³.

        The procedure

        A combination of treatment processes were selected to ensure that the facility always treats the wastewater to the same high standard despite the different qualities of water at the plant – generated on the one hand by the production activities and, on the other hand, by the plant's cleaning activities. The wastewater treatment is carried out using a flotation process which had already been installed. The ensuing main treatment phase is performed in a one-line membrane bioreactor (MBR) facility with immersed ultrafiltration membranes and a sludge treatment stage.
        This combination of wastewater treatment technologies saves space, conserves resources and produces water which can be directly discharged.

        The benefits

        • Reliable and cost-effective method to treat wastewater

Both plants treat about 1,000 cubic metres of wastewater each day this way. As an additional service, the resulting mango peels were composted.

        The benefits

        • Safe effluent treatment through modern technologies
        • Holistic resource and environmental protection

      DMK Deutsches Milchkontor, Altentreptow // Germany

      • Electricity from wastewater

        DMK Deutsches Michkontor GmbH, the result of a merger between Humana Milchindustrie and Nordmilch, employs approx. 5,500 people and has an annual turnover of around 4 billion euros. Its Altentreptow and Bergen sites generate an annual turnover of approximately 220 million euros.

        The project

        DMK Deutsches Milchkontor GmbH runs a classic dairy business with cheese production at its Altentreptow site. In 2006, this was then joined by a whey processing plant owned by wheyco GmbH – a company belonging to the DMK dairy corporation. As a result of the expansion of the production site, REMONDIS Aqua was commissioned with the task of extending and operating the wastewater treatment system. In 2008, it was then awarded a second project to build and run a much-needed further extension to the wastewater treatment facility.

        The procedure

        Wastewater generated from cheese production and whey processing contains high levels of organic matter – a big challenge for the treatment process. REMONDIS Aqua developed a cost-effective solution: a large percentage of the pollutants are transformed into biogas during the initial treatment phase by using an anaerobic process and then generated into electricity in REMONDIS' own combined heat and power plant. In order to ensure that the energy potential is used in the best possible way, we use the heat generated in the power plant for the treatment process (combined heat and power). In addition, a further procedure was integrated into the system to recover phosphorus, namely our patented REPHOS® process.

        The benefits

        • Safe treatment of wastewater
        • Integral concept to conserve natural resources and protect the environment
        • Greater cost effectiveness

      Deutsche Nickel, Schwerte // Germany

      • Optimised wastewater treatment

        Deutsche Nickel GmbH can look back on a long and successful history. It has, for example, been processing metals for more than 100 years now at its Schwerte site alone. The company is one of the world's leading producers of materials from nickel and nickel alloys.

        The project

        REMONDIS Aqua has been responsible for operating the plant's wastewater treatment facility in Schwerte since 2002. Since then, we have upgraded and optimised both its technology and control system. In addition, we have provided a water pollution control officer for Deutsche Nickel GmbH to help the company fulfil its legal obligations.

        The procedure

        The production of materials from nickel alloys, non-ferrous metals and stainless steel generates highly polluted wastewater. We use a special process, developed by our own experts, which reliably removes the heavy metals from the water.

        The benefits

        • Modern plant technology
        • Optimised processes
        • Safety guaranteed thanks to the special procedures
        • Time saved by outsourcing

      BP, Gelsenkirchen // Germany

      • Turning sludge into oil and water

        BP Gelsenkirchen GmbH is a joint venture between Deutsche BP AG and the Venezuelan state oil company, Petróleos de Venezuela S.A. Both partners hold a 50% stake in the joint venture, which was established back in 1983.

        The project

        Within the framework of a company partnership, REMONDIS built an oil sludge treatment plant at BP Gelsenkirchen's Horst site. We provided all of the services involved – from drawing up the concept, to managing and financing the project. The chemical-physical treatment facility has the capacity to process 25,000 tonnes a year. The oil that is recovered is returned for processing and the remaining wastewater is treated.

        The procedure

        Before treatment, the liquid and solid elements are first separated from each other. The settled sludge is used, among other things, to produce substitute fuels; the liquid elements undergo further treatment stages, including the use of organic separating agents and splitting up emulsions by reducing pH values.

        The benefits

        • Conserves natural resources and protects the environment
        • Highly efficient processes and procedures

      Wild Valencia, Carcaixent // Spain

      • Secure treatment of electroplating effluents

        Polyplastics Industries is a leading Indian manufacturer of plastic accessories with a history of over 50 years. The company specialises primarily in spare parts for the automotive industry and offers a comprehensive range of products. The Viragram site is one of the 8 sites in India. The main production processes are injection moulding, painting and electroplating. 

        The procedure

        The wastewater, which has a high sugar content, undergoes anaerobic and thus energy-saving preliminary treatment. The primary task here is to remove the organic contents. The energy stored in the wastewater can be recovered as biogas. The company benefits as the biogas is used to substitute natural gas in its production processes. A second volume of wastewater, which contains high levels of sulfate, is treated using a high performance aerobic system.

        Sugar-free thanks to modern process technology

        The plant in Carcaixent, Spain – in the orange-growing region of Valencia – extracts fructose and produces a variety of flavours for the food and drinks industries.

        The project

        Wild Valencia is a subsidiary of Rudolf Wild GmbH & Co. KG, a company based in the German city of Eppelheim, and is most well-known for its successful soft drink Capri-Sun. With the business at the plant in Carcaixent, Spain, developing rapidly, the company decided its existing wastewater treatment facility had to be expanded. REMONDIS Aqua built a new facility and is now responsible for its operations management.

        The benefits

        • Safe, efficient and cost-effective treatment
        • Generation of biogas using a special process
        • Energy recovered and returned to the production cycle
