VH TECH - Small wastewater treatment VH

Small wastewater treatment VH are biological wastewater treatment systems for up to 50 residents . The quality of effluent water meets hygiene and water management requirements .
Wastewater treatment plants are used to treat waste water from smaller objects (houses , apartment buildings , restaurants , hotels , schools, kindergartens , services , office and factory areas, etc. ).

Modern solution

Modern solution of sewage tratmnent systems VH meets the strict criteria of European legislation . thanks to the fact that sewage treatment systems consist of the most advanced features, customers are provided maximum ease of maintanance. Power consumption is low, the operation is very simple . Sewage VH work odorless , silent and with extraordinary effectivity. Their installation is quick and easy.

 

How does sewage treatment systems work?

Sewage treatment system consists of denitrification , oxic and separating space . The denitrification space leads to removal of mechanical impurities , fat and nitrogen pollution . In oxic space is aeration system in which air blower forces air. In this area there is a removal of organic contamination. The separation area is separated from the purified water sludge. Treated water flows into a watercourse or catch-drain. Sludge is recirculated to the process. All wastewater systems are operated by valves on the manifold.

 

Technical specifications

Wastewater treatment plants are working on mechanical and biological principles and are the treatment of sewage from all sources of organic pollution ( kitchen, bathroom , toilet , etc. ).
They are designed according to European standards ( EN 12566-3 ). They have high resistance and durability. Operation of wastewater is simple and reliable. They also work well with mild intermittent flow of waste water in winter.
Upgraded quality of treated water meets hygiene and water-management requirements. Treated water can be discharged into a watercourse or catch-drain.

∗∗ WWTP ** Height can be adjusted according to customer requirements.

 

Replacing the WWTP

The device is preferably placed in the exterior and it is imbedded on the concrete slab below ground level. It is connected to horizontal drains, while the diameter of inflow and outflow pipes device can be adjusted to the production. The depth of sewer is chosen according to the height extension. The way of embedding a particular facility should be ordered with the supplier.

Technological parameters

wastewater treatment system VH achieves high cleaning efficiency ( up to 95-99 % ) , at low power consumption . 

 

 

 

 

Products have been tested in several European accredited laboratories. Modern and economic purification was confirmed by more certificates.
