Water treatment

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


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

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.


The ENVI-PUR EP-C clarifiers are universal equipment for continuous separation of the suspended substances from the liquid environment. Their applications are very comprehensive and they include:

  • Drinking and technological water
    • clarification of surface waters
    • softening of surface waters
    • softening of underground waters
    • separation of Fe and Mn from underground waters
  • Industrial waste water
    • waste water treatment by clarification and precipitation procedures
  • Town waste waters
    • removal of phosphates by applying the precipitation procedures

Lamella pack cassettes

Cartridges with lamella blocks in the sedimentation area of existing or new sedimentation tanks and clarifiers allow significant increase of surface loading of the equipment while the solid phase's separation efficiency is maintained or improved.

UV disinfection

UV systems ensure a modern hygienic  provision of water according to the applicable legislation and they replace fully the indelicate chlorination method when the chlorine derivatives that are harmful to health (carcinogenic) may be generated.

  • Disinfection of crude water from the local sources (wells, boreholes, catch basins, etc.).
  • Water disinfection in the system, especially downstream the activated carbon filter where dechlorination takes place.
  • Disinfection of the recycled rain water for utility purposes.
