Problems
Nowadays the following tasks connected with wastewater treatment are considered to be topical:
- organic matters treatment effectiveness increase,
- excess sludge mass reduction,
- construction and maintenance expenses reduction,
- reuse of treated water.
Suggestions
"Complect Ecology" produces module container type Plants and Stations of full factory completeness at capacity of 9 - 3000 m3/day which are used for municipal wastewater treatment and similar one. The technology has been worked out especially for meeting strict environmental standards as well as for location and operation in the area of strict sanitary control. The technology enables to achieve the following treatment indicators:

Solving
Comparing to such widely known technologies as A20, 2A20, UCT, VIP, the projects implementation according to "Complect Ecology" technologies have the following advantages at the same capacity and loading:
- high treatment effect,
- full biological self-regulation,
- stability of biocenosis to peak load and high resistance to changing parameters,
- reduction of construction area,
- treatment cost reduction,
- significant reduction of both maintenance time and necessity of experienced labour power intake,
- treated sludge reduction,
- treated water reuse availability,
- possibility of expansion,
- absence of odour and noise
Explanation
Treatment process takes place in aerated tanks at the expense of fixed biocenosis developing on special plastic media. The multi-levels process enables to treat the effluent with high load on sludge on the first steps to low load - on the final steps. The specific conditions allow both the processes of nitrification and denitrification to take place simultaneously. Due to balance between bacteria development and metazoa growth our stations and plants work with minimal sludge increase that excludes sludge drying beds construction. High treatment efficiency as well as complete biological disinfection allows using treated water repeatedly for watering, technical and other needs.
As the logic of natural process simple and clear, high skilled maintenance staff is not necessary. All components providing for the process are cheap, durable and broadly available. All equipment works in automatic mode.
Container type plants and stations provide for stable operation in northlands and in seismic active areas.
Application
Settlements, cottages, hotels, hospitals, restaurants, schools, campings, etc.
