PROCESSING THE WASTEWATER TREATMENT SLUDGE

WE KNOW YOUR WASTE

Wastewater treatment plants clear away the rests from cooking, bathing, washing and also faeces from the wastewater from municipalities. And from the agricultural wastewater, they clear away the industrial fertilizers, pesticides, vegetable waste, etc. The dirt from water is concentrated into the sludge that is infectious and ecotoxic. It is classified as hazardous waste by law that also imposes an obligation to designate a program on its use to all sludge producers. EU waste policy wants to prevent sludge landfilling and Czech legislation bans it. Environmentally friendly, sustainable and economically acceptable solution for sludge processing is demanded.

WE KNOW WHAT TROUBLES YOU 

Sludge smells bad, it is contaminated by thermotolerant coliform bacteria, enterococci, Salmonella, E. coli, viruses and parasites. It is infectious, ecotoxic and usually contains heavy metals, especially As, Cd, Cr, Cu, Hg, Ni, Pb, Zn and organic contaminants AOX, PCB, NEL and PAU.More than half of the costs on wastewater treatment are spent on sludge processing. It has to be sanitised and stabilized to make it usable with no negative impact on human health and environment. 

EWA fermenter meets all these conditions on sludge processing. It is an environmentally friendly, sustainable, and economically acceptable solution. Sludge processing in EWA prevents negative impacts on the environment and human health.

WE KNOW THE SOLUTION

The problematic biodegradable waste (BDW), usually expensive to dispose of, can be used and turned into an eco-friendly, beneficial and profitable revenue stream. Integrate the aerobic fermenter EWA to your operation and simply load and unload all the BDW by a built-in conveyor.

EWA - Ecological Waste Apparatus

EWA is an original apparatus designed for ecological processing of biodegradable waste, including the sludges from wastewaste treatment plants and animal by-products. On the market today, EWA is the most advanced in-vessel fermenter with 100% guaranteed hygienisationof the whole fill.

An original, patented solution of turning the fill in combination with rotary cultivators, system of air injectors and processes monitoring ensure an optimal conditions for bacteria to reproduce. The whole process of fermentation is shortened to minimum with maximum effect.

Ewa can process widest range of biodegradable waste.

The output material (fermentate) is either fresh compost, a first quality compost or biofuel.

The controlled proces of fermentation produces heat inside the machine, so there is no need of external source heat.

EWA is the most effective technologie for BDW processing on the market today.

BENEFITS OF COMPOSTING IN EWA

The material heats by itself in the fermenter which destroys pathogenic germs and compost is no longer infectious. After the fermentation, there is no bad smell, no dung water, no vectors, no pathogens, no dangerous viruses, no bacteria, no eggs and larvae, that could find their way to humans through the soil. As the material has no bad smell any more, it is possible to stock it even in densely populated residential areas.

The fermentation process takes place automatically and it hygienizes every biodegradable waste you load in.

No longer will you have to pay for disposal of the biodegradable waste. You can safely return hygienized waste to the soil, use it for heating or sell it to producers of soil conditioners and fertilizers or directly to local gardening shops, they will be happy to save money on buying expensive commercial substrates or artificial fertilizers.
