Small wastewater treatment systems VH-L

mcovvhlskica_393Small wastewater treatment systems VH-L are biological wastewater treatment systems for up to 50 residents . The quality of effluent water meets hygiene and water management requirements.

Sewage treatment systems VH - L are adequate and cheaper substitution for sewage treatment system
VH . They are used to treat waste water from smaller objects, such as family houses, apartment buildings, restaurants, hotels, schools, services, office and industrial areas etc.

Compact solution

The design of the sewage tratment system VH-l allows quick and easy installation, these types of wastewater tratment systems can be fitted into the smallest space in the smallest residential buildings.

Its compact size makes easy to set and operate the sewage tratment system . Efficiency of the device is up to 92 % - 98 %.

mcovvhlpopis_321How does sewage treatment system work?

Sewage treatment system consists of primary, oxic and separating space . The primary area leads to the removal of mechanic impurities and some 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 . The source of air is airblower with minimized power consumption . Blower runs on time cycles and is usually placed outside the water treatment system.

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 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 . Excess sludge can be used for composting and fertilizing ornamental plants.

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.
