Technological solutions of "Complect Ecology" in the field of wastewater treatment are directed at solving ecological problems of enterprises belonging to different branches of industry characterized by high pollution content. The technology is based on two-stage treatment of strong industrial wastewater including both physical-chemical and/or biological stages of treatment.
Application
- Milk processing manufacturers.
- Meat processing manufacturers.
- Beer and beverages manufacturers.
- Alcohol manufacturers.
- Wine manufacturers.
- Starch and treacle manufacturers.
- Sugar manufacturers.
- Confectionery manufacturers.
The capacity of technological equipment depends on wastewater flow rate, contaminants concentration and required treatment level. Variants of equipment packaging and the efficiency of technological scheme operation are determined by both Customer's wish and control authorities requirements.

The application of scientific achievements and practical experience allows to improve industrial enterprises' drain system with maximal economic effect. Module type equipment allows to enlarge the total capacity stepwise while the production is also developing.
Principal technological scheme
Technological process
 Pretreatment
On the first stage the compact and energy efficient unit of physical-
chemical pretreatment is used. The action of the unit is based on the process of
flotation filtration with simultaneous change of the dissolved matters
structure, but (unlike similar offerings) it needs neither use of reagents
nor large area for equipment installation. The simplicity of structural
solution allows to reach the normal operating mode in short term, and
the equipment does not need constant presence maintenance staff.
This equipment allows to decrease the contamination concentration by
70-95% on the stage of preliminary treatment and to reach the
parameters of effluent, permissible for urban collecting channel.
 Complete/deep biological treatment
On the stage of complete biological treatment (up to the characteristic permissible for discharge into fish industry pond) the intensified technologies of biological treatment are used. The unique technological solutions are based on the use of fixed biocenesis (sludge) on the special media (carriers), which, owing to balance between growth of bacterial sludge and protozoa, operate with minimal increase of excess sludge. The suggested technology has following basic advantages:
- high intensity of the processes;
- resistance of biocenosis to extreme situations (irregularity of loading, temperature, pH, electric power supply etc.);
- ecological compatibility of the offered wastewater treatment plants;
- significant reduction of both excess active sludge increase and maximum spending on sediment, excess sludge utilization without sludge and sand beds application;
- reduction (2 times) consumed electric power;
- opportunity of enlargement;
- high intensity of processes;
- high-performance production, integration and durability;
- short pay-back period of investment in wastewater treatment facilities.
