For towns and villages

Compact WWTP

Compact WWTPs BioCleaner® are an optimal solution for villages and towns up to 10 000 citizens. These plants may also be applied for treatment of organically polluted industrial sewage water, especially from the food industry.

Technological layout of the WWTP, but also the building and architectural design is always designed exactly to the investor’s requirements and appropriate institutions of state administration.

WWTP can be made as one-line up to four-line (parallel lines) organization, which enables reacting to up-to-date load at the gradual sewerage built-up or reacting to seasonal inequalities in tourist areas. WWTP can be made as an open-air or partially covered or fully covered unit in order to adopt to hygiene and other requirements.

Aeration systems

We offer high-quality fine-bubble, medium-bubble and coarse-bubble aeration systems intended to aerate activation tanks of municipal and industrial waste water treatment plants and to aerate and mix the tank contents. They are suitable for both permanent and intermittent operation.

Membrane WTP

This unique technology is designed for drinking and process water treatment, by using ceramic membrane microfiltration. It's suitable for one step surface water and under-ground water treatment.

  • Mobile and stationary arrangement
  • High performance, high reliability
  • High operation stability (stable filtrate quality during fluctuation of raw water quality)
  • Long service intervals and long life time
  • Sufficient for emergency drinking water supply

Flotation (DAF)

Dissolved-air flotation (D.A.F.) is a separation process, which is used as the first separation step during drinking water treatment.

The D.A.F. system employs a physical process whereby very fine air bubbles (microbubbles) attach themselves to low density particles suspended in the water and float them to the surface where they form a floating sludge blanket, that is easily removed.

  • High loading rates
  • Compact design
  • Effective operation
  • Longer filter runs
  • High sludge concentration
  • Steel or concrete tank installation
  • Rapid start-up

Flotation for WWTPs (DAF)

Dissolved Air Flotation (DAF) is a separation process that is successfully employed for preliminary cleaning of the concentrated industrial (namely the food-industry) waters with higher content of suspended solids and fats.

Fat separators

Grease traps are intended for trapping the oils and fats that flow off in waste waters from kitchens, food-processing plants, meat processing, etc. Grease traps are installed to the waste water sewerage leading from the space where the waste waters containing fats are generated and as close to the generation point of these waters as possible.

Oil substances separators

Petroleum product separators are used to separate and trap the free petroleum products (NEL) born by the runoff from roads, solidified parking surfaces and lay-bys, handling areas, garages, car repair shops, washing ramps, etc.

Small Pump Sumps

ENVI-PUR, s.r.o. manufactures and supplies small pump sumps that are designed mainly to re-pump the waste waters where the height differential makes it impossible to run a direct connection to the sewerage. These pump sumps can be also used for accumulation of rain waters that can be consequently used for irrigation.

Water Filtration

When the S/SL type Leopold drainage system is used, uniform distribution of washing air over the entire filter area allows to obtain excellent results in filter washing, namely with different composition of the filtering medium's layers.


Filtralite is a new filtering material intended for drinking water treatment, suitable for the open pressure and biological filters.

Clari-Vac Settling Tank

The Clari-Vac technology is intended for the new and existing square secondary settling tanks. The advantage of this system is its low demand for energy and investments. One recirculation pump ensures both internal and external recirculation, removal of excessive sludge into the sediment trap as well as the transport of floating impurities. Very low energy is also required to drive the float with pipe structure and the floating impurity removal system.

Locksmith's Production

The metal and locksmith production products find their use also in the technological units in the area of water and air purification and treatment.
