EnviroChemie was founded in Switzerland in 1976, moving its headquarters to Rossdorf near Darmstadt (Germany) in 1996. A number of other companies have since joined the Group; EnviroDTS in 2001, EnviroFALK in 2006 and AWATEC AG in 2009. The whole Group was brought together under the EnviroWorld trade name in 2009. EnviroChemie GmbH operates five manufacturing and development sites in Germany and Switzerland as well as a further ten sales and service facilities, located mainly in Eastern Europe and Brazil. All plants, including user-friendly automation and measuring technology, are manufactured in EnviroChemies own factory. 20 pilot plants are available for testing purposes. With its 300 engineers and experts in water technology, the company achieved a turnover of 70 million euros in 2009. Eighty percent of turnover comes from plant construction in foreign markets. Twenty industrial property rights have been granted or applied for. EnviroChemie GmbH operates in the area of industrial water and wastewater technology, providing plant solutions and services for resource-efficient production. The company’s expertise lies in recycling water and other materials, optimising production processes, increasing efficiency, generating energy in a resourcefriendly manner and intelligent solutions for the treatment of process and wastewater. It supplies its industrial customers with a wide range of services, including consulting, planning and surveys, as well as plant construction, pilot testing, planning application and comprehensive servicing. EnviroChemie is a leading European company in the industrial treatment and recycling of wastewater and the market leader in Germany in the field of decentralised, compact wastewater treatment plants using chemico-physical, biological and membrane technology processes. To date, some 13,000 such systems have been delivered. A more efficient use of resources and a reduction in effluent contamination benefit not only the company’s customers but also the environment. One particularly outstanding innovation from EnviroChemie is the so called Biomar biological process, which demonstrates how environmental and economic criteria can be reconciled in an intelligent fashion. This process for the treatment of industrial effluent with high organic contamination involves an anaerobic stage followed by a secondary aerobic stage. Compared with purely aerobic processes, it uses significantly less energy, and in addition, energy can be generated from the produced biogas. The Biomar AWR process is applied in the dairy industry and uses whey, a by-product from cheese manufacture, as an alternative source of energy. The energy-rich whey is converted into biogas in special methane reactors, and this in turn produces steam, electricity or hot water, i. e. energy that can be fed back into the production process. In the Norrmejerier dairy in Umeå (Sweden), 200 tonnes of whey per day are turned into biogas in this way. This leads to savings in labour costs and equipment as well as a reduction in residues and emissions. At its manufacturing site in Mettlach, Villeroy & Boch AG was equally looking for a process to use resources more efficiently while reducing emissions. The objective was to recover the residues of porcelain glazes from wastewater in order to cut back on effluent and re-use the high-value residual materials. EnviroChemie was brought in to install a plant fitted with ceramic microfiltration modules. Using the principle of cross-flow filtration, it is possible to retain the glaze particles. The recovered glaze concentrate and the clear filtrate are then fed back again into the production process. In the field of physico-chemical processes, EnviroChemie can offer plants for treating wastewater and recycling process water (Envochem), plants for cleaning small quantities of highly contaminated wastewater (Split-O-Mat), high-performance flotation plants for larger quantities of wastewater (Flomar) and plants for the further treatment of wastewater from washing processes (Lugan). EnviroChemie offers a comprehensive water management service, comprising process analysis, pilot testing on site or in its own test laboratories, plant construction, maintenance and repairs and plant operation. Product lines, processes and components are developed not only at the company’s own facilities but also in longstanding and successful partnerships with research institutes such as the Fraunhofer Gesellschaft and various universities. As part of the AKIZ research project (an integrated wastewater concept for industrial areas using the example of Tra Noc in Vietnam), EnviroChemie is building an innovative pilot plant for recovering materials using membrane technology.
