Biological treatment plants of domestic wastewater for private houses
Purpose

 

NV-X 1÷4 type biological treatment plants of domestic wastewater meets the requirements of the EU Directive 89/106/EEC and all the provisions of Annex ZA to the standard EN 12566-3:2006+A1:2009“Small wastewater treatment systems for up to 50 PT – Part 3: Packaged and/or site assembled domestic wastewater treatment plants”.  
EU Declaration of Conformity 
Notified body: Public company Certification Centre of Building Products (li, Statybos produkcijos sertifikavimo centras, SPSC), Wastewater Treatment Plant Testing Laboratory (li, Nuotekų valymo įrenginių laboratorija), Linkmenų st. 28, LT-08217 Vilnius, Lithuania, notification No. 1397.


NV type biological treatment facilities of domestic wastewater, sold in Lithuania, Poland, Russia, Macedonia, have been produced since 1996. 

NV type aerobic plants are most often used for treatment of domestic wastewater for private houses. Equipment is installed, where there is no possibility of connection to centralised sewage networks. 

NV type biological treatment plants of domestic wastewater are intended for treatment of domestic or similar wastewater from the kitchen, bathroom, toilet and other similar-purpose facilities. Substances that cannot enter the treatment plant are as follows: 
  • surface wastewater (off the roof, from the yard, etc.);
  • wastewater from a garage and other non-domestic – purpose facilities;
  • water from a basin or other receptacles that are larger than 1m3;
  • chemical substances, entering into sewage system of which is not provided according to their usage (oil products, agrochemical substances, etc.);
  • water after regeneration of filters of softening/removal of iron;
  • chemicals used at home (washing means, bleaches, softeners, degreasers) shall be use as provided in manufacturer’s recommendations.

Equipment advantages: 

▪ factory enclosed biological treatment unit for domestic waste; 
▪ various capacities; 
▪ high level of treatment, removed 95–98% of pollutants; 
▪ no internal movable parts to be supervised or replaced; 
▪ serviceable, light-weight glass-fibre structure (easy transportation); 
▪ quiet operation and no offensive odour diffusion; 
▪ treated discharged water – transparent and odourless; 
▪ minimum power consumption; 
▪ no need in auxiliary filtering equipment; 
▪ easy maintenance and process automation; 
▪ easy installation. 

Treatment plant is used as an underground facility. Supplementary collection (riser rings) depends on manifold deepening. Subject to the selected place, treatment plant may be installed in a green lawn or under the roadway (not recommended due to uncomfortable maintenance). 













HNV type biological treatment plants of domestic wastewater for settlements and newly built quarters
Purpose

 

HNV type domestic wastewater treatment plants for settlements and newly built quarters are intended for treatment of domestic or similar wastewater from the kitchen, bathroom, toilet and other similar-purpose facilities. 

Substances that cannot enter the treatment plant are as follows:

  • surface wastewater (off the roof, from the yard, etc.);
  • wastewater from a garage and other non-domestic–purpose facilities;
