Wastewater Treatment — Case Studies
Due to long-term expertise in the area of wastewater treatment DAS Environmental Expert can refer to various case studies that demonstrate the turnkey expertise from optimization to if existing plants to the engineering of new wastewater systems.
Flexible, scalable and reliable: DAS builds wastewater treatment plant for DSM Nutritional Products AG
Increasing production capacities have brought the existing wastewater treatment plant at the chemical company DSM Nutritional Products in Switzerland to the limits of its capacity. Wastewater properties in the chemical industry with strict limit values in the food and beverage industry — the DAS experts mastered the challenge and installed a two-stage MBBR plant.
Multistep clarification process on the way to pure water
Safety for people and the environment is Roche’s top priority for the whole rehabilitation. Since the groundwater below the Kesslergrube landfill has also been contaminated with industrial materials, a bored pile wall was erected and well galleries were established in preparation for the excavation measures. The solution offered by DAS Environmental Expert GmbH for groundwater treatment as part of the
Construction of a new flotation system to optimise biological wastewater treatment at ARA Rhein
ARA Rhein treats industrial and municipal wastewater from the catchment area in Pratteln in a 2‑stage biological process. DAS Environmental Expert GmbH was responsible for the new construction of a two-stage flotation plant.
Clever Wastewater Treatment System for Production Expansion in the Beverage Industry
The treatment of wastewater in the beverage industry usually has to manage unstable water flows. In the case of the South American soft drink manufacturer Refres Now S.A. significantly increasing manufacturing volumes also had to be faced. Therefore, the wastewater system was adopted to the new conditions by the Environmental Experts from DAS.
Conversion and Expansion of an Existing Dairy Industry Wastewater Treatment System
In 2016, the DMK group announced the investment in its Strückhausen branch in order to start producing skim and whole milk powder for baby food. Environmental Expert Dresden is commissioned to comprehensively modernize and expand the DMK Group’s wastewater treatment system.
Cost-efficient Treatment of Landfill Leachate
The composition of landfill leachates differs depending on the type of waste stored, the weather and the holding time in the landfill body. Besides the safe leachate treatment a strong reduction in odour was achieved for the Grumbach landfill.
Energy Efficient Wastewater Plant Applying Wastewater Heat Exchanger
Wastewater heat exchangers ensure the reliable operation of a wastewater treatment plant and enable the recovery of heat from the wastewater stream. The E‑Plate heat exchanger offers many advantages compared to conventional systems and represents an efficiency-increasing solution for solids-laden wastewater.
Expansion of the Aerobic Biological Wastewater Treatment Plant in the Food Industry
Potatoes are powerful: Next to processed products the potato can serve as an energy supply. This is what Friweika eG, a potato processing business in Weidensdorf (Germany), is exemplary in demonstrating.
From Manufacturing into The River
More and more users from the food industry as well as manufacturers of wastewater treatment plants rely on the advantages of sustainably designed wastewater treatment concepts. The TFR technology offers many advantages. The wastewater treatment plant at Fromageries Bel in the south of Vietnam is a good example to describe this process in more detail.
Biological Treatment of Wastewater in the Chemical Industry
Biological processes become more and more popular in wastewater treatment — even for the demanding conditions in the chemical industry. This will be explained in detail in this case study using various examples.
Case studies of pilot plants for wastewater treatment
Not all wastewater is the same. The wastewater specialists at DAS develop cost-effective plant solutions which guarantee the best wastewater treatment results possible for our customers. After initial laboratory testing, we often run a pilot plant under real-life conditions directly at the customer’s site to ensure that the plant configuration is optimal.
