DEWATS | Decentralized Wastewater Treatment Solution

DEWATS stands for “Decentralized Wastewater Treatment Solutions”. DEWATS is rather a technical approach than merely a technology package.

DEWATS applications are based on the principle of low-maintenance since most important parts of the system work without technical energy inputs and cannot be switched off intentionally.
DEWATS applications provide state-of-the-art-technology at affordable prices because all of the materials used for construction are locally available.

DEWATS applications provide treatment for both, domestic and industrial sources
DEWATS applications provide treatment for organic wastewater flows from 1-1000 m³ per day
DEWATS applications are reliable, long lasting and tolerant towards inflow fluctuation
DEWATS applications do not need sophisticated maintenance

Without considering facilities for necessary chemical pre-treatment of wastewater from industries, DEWATS applications are based on four basic technical treatment modules which are combined according to demand:

Primary treatment: sedimentation and floatation
Secondary anaerobic treatment in fixed-bed reactors: baffled upstream reactors or anaerobic filters
Tertiary aerobic treatment in sub-surface flow filters
Fourthly aerobic treatment in polishing ponds

DEWATS applications are designed and dimensioned in such a way that treated water meets requirements stipulated in environmental laws and regulations.
