Heim-statt Chernobyl e.V.

The new STP was built as a constructed wetland (reed bed). As ecological variant it fits very well into the sustainable and ecological development concept of the village of Drushnaya. The first reed bed treatment plant in Belarus serves as a pilot project for the entire region, for villages and small settlements which until now have used septic tanks for wastewater disposal.

Drushnaya is already attracting many visitors and delegations from home and abroad, especially because of its ecological orientation in combination with successful community work.

The project has been realized with the strong support of SWT Schulz Wassertechnik, Ingenieurbüro, 35423 Lich, Germany.

April 2019 - Serbia: High Energy Efficiency for Optimized OPEX

Power costs are the driving cost factor for OPEX and determination of the water tariff.

In pre-accession countries with an urgent demand of high inestments for upgrade of the National power grits and new power plants a dramandous increase of the electricity tariffs must be expected in the coming years!


Considerations for WWTP design and the software we use:

- Optimized, multilane design at conservative determination of design capacity

- State of the art process design (i.e. aqua-designer)

- High efficient electric installations and motors (VDE 0100-801)

- High efficient aeration systems with modern plate aerators (i.e. aqua-aero)

- Advanced process control and reporting (i.e. aqua-und-bio-provi)

- Monitoring of power consumption (i.e. provi-energy)

- Anaerobic sludge stabilization (≥ 10.000 P.E.)

- WAS-Disintegration in order to increase gas production and reduce sludge production

- Trigenergration (CCHP) ... cover AC-cold demand with excess heat

- Consider advanced thermal efficiency requirements for buildings   

- Solar sludge drying with mono-landfill in order to keep the P-resource (future processing)

- Sludge Pyrolysis for fertilizer production

- Training and continous further education of operators (i.e. provi-online)



Current design example


Additional power saving potentials are:


• Archimedian screw pumps

• Step-feed process

• Sludge pyrolysis after thermal

   sludge drying


Gross power demand below

20 kWh/P.E./a for wastewater and sludge treatment are feasible at nominal design capacity and loads!




Advanced WWTP design reduces the gross-power demand of wastewater and sludge treatment and the carbon footprint as well as green house gas emissions of the plant!

April 2019 - Montenegro: Serial Production of Preliminary WWTP-Designs

Overcoming the sanitation problems in the touristic areas of Montenegro is a challenge due to rugged topography which requires de-centralized wastewater treatment. The coastal areas are declared as "sensitive area" in acc. with UWWD 271/91 requiring advanced treatment in acc. with the revised BWD 2006/7/EC.

Tourisim requires seasonal operation of WWTP's under particular consideration of energy efficiency requirements and implementation of an applicable sludge management strategy.

March 2019 - Sludge & WWTP Graphs
