Technical data


Note not all wastewater treatment plants feature such high parameters of treated water. Application of active sludge technology requires no additional filters and no other equipment (unless requested by the client or project conditions).
This is a cost-effective and environmentally-friendly method.

Here is a comparison chart for your use in comparing our wastewater treatment plant with our competition.

Although we have listed our two smallest plants, all our residential treatment units are accredited with the same data up to 50 persons. For data on larger units please contact us for more information.
