Solutions for water & wastewater treatment

Put the challenges of your wastewater management in our hands. As specialists in water treatment and reuse, our DAS Environmental Experts develop technically and economically optimal solutions – tailored to your needs.

Tailor-Made Wastewater Solutions between Standardisation and Individuality

Every industrial company is looking for an optimal wastewater treatment solution. However, the requirements are unique for every project. Our DAS products and combined solutions offer a perfect interplay between the advantages of standardisation and the individual needs of each customer - regardless of whether a single biological treatment stage for the wastewater is to be installed, a complete wastewater treatment plant is to be built or an entire factory is to be equipped with wastewater technology.

OTTELIA – Efficient Wastewater Treatment for the Semiconductor Industry

Produkte

OTTELIA is the intelligent point-of-use solution for the reliable removal of silicon dioxide particles (SiO₂) from process wastewater in semiconductor manufacturing. Thanks to a state-of-the-art combination of sedimentation and filtration, OTTELIA enables direct water reuse, reduces fresh water consumption, lowers operating costs and supports companies in achieving their sustainability and ESG goals. With its compact design, high separation efficiency and flexible scalability, OTTELIA can be seamlessly integrated into existing production and waste gas treatment systems.

SALVINIA – Standardized MBBRs in four Sizes

Products

In the product group SALVINIA we combine effectiveness and compactness with time and cost benefits for our customers. The MBBRs (Moving Bed Biofilm Reactor) are available in four standard sizes SALVINIA 70, SALVINIA 170, SALVINIA 470 and SALVINIA 1060 can be used in a variety of ways in all industries for the biological treatment of industrial wastewater.

E-PLATE – Wastewater Heat Exchanger

Products

Wastewater that is too warm is a challenge for many of our customers. With the E-PLATE heat exchanger, we offer a flexible product that both optimizes the temperatures of your water flows - e.g. the cooling of wastewater to ensure the functionality of a biological treatment stage - and significantly reduces the energy requirements of your wastewater treatment plant. This is because the energy recovered from the wastewater can be used to heat the required fresh water, for example. The E-PLATE is therefore a multifunctional talent whose initial costs are often amortized within the first year!

Centralised & Semi-Centralised Wastewater Treatment Plants

Every customer has individual requirements for their wastewater treatment plant. These have a significant impact on the design, technology, location and size of the plant. We offer centralized, semi-centralized and point-of-use systems, giving our customers the opportunity to choose the approach that best suits their specific needs. In addition, the modular design of our system components means that our DAS wastewater systems are largely prefabricated and delivered to their installation site for easy assembly.
