Use less water, producing energy and fertilizer at the same time

Vacuum sewage systems reduce water consumption

Vacuum sewage is a key building block. The concept drastically reduces water consumption. Vacuum toilets need only about 0.5 to 1 liter of water per flush. By comparison: Conventional toilets use between four and eight liters.

What's more, the investment and maintenance costs are lower than those for conventional sewage systems. Domestic wastewater is biologically purified in an anaerobic, high-performance membrane plant. The heart of the system, fully-mixed anaerobic bioreactors, treat the wastewater without aeration or oxygen and the organic constituents are converted into biogas, a mixture of methane and carbon dioxide.

The bioreactors are combined with rotation disk filters. The wastewater is forced through ceramic filter disks. The rotational movement of the ceramic membranes inhibits the formation of covering layers. So the filtration capacity is maintained over a prolonged period. The purified water drains into the filter plant's hollow shaft. The pores in the membrane range in size from 60 nanometers and 0.2 micrometers. All larger particles are routed into the bioreactors. Bacteria are also returned to the reactors, which breakdown the organic waste that has been filtered out. The recovered biogas provides power and heat. The entire plant works in the absence of air. The benefit: there's no bad odor.

Recovery of biogas and fertilizer

Another special feature of the disposal concept: As well as domestic wastewater, the wastewater purification plant can also process bio kitchen waste. Kitchens are simply equipped with a waste macerator, accommodated below the sink. The system is connected to the domestic wastewater pipes. As more and more organic waste gets into the wastewater, the biogas yield increases. Bio-waste and wastewater produce another by-product: fertilizer. Nitrogen and phospho
