ZAVKOM-ENGINEERING at the International Exhibition “EcwaTec 2025”

Within the framework of the project, the following were supplied: tank, filtration, and heat-exchange equipment, pumps, decanter, evaporator, salt column, heating chamber, cooling towers, centrifuges, ejectors, and shut-off and control valves.

Scope of supply:

1. Process design
2. Development of RDD
3. Manufacturing and supply of equipment
4. Supervision and commissioning works
5. Personnel training

The Baikal Pulp and Paper Mill operated from 1966 to 2013. It was the city-forming enterprise of the single-industry town of Baikalsk. The plants supplied by LLC "ZAVKOM-ENGINEERING" are part of a station for treating alkali-containing effluents with a capacity of 2,000 m³/day. Infrastructure for the purification and removal of supernatant waters at the Solzansky site is being created within the framework of the federal project for the remediation of accumulated environmental damage caused by the Baikal Pulp and Paper Mill.

Supply and installation

Scope of supply:

1. Process design
2. Development of detailed design documentation (RDD)
3. Manufacturing and supply of equipment

Scope of supply:

The reverse osmosis concentrate polishing unit is located in a prefabricated building, common for three lines, and includes:

• Reagent softening unit for concentrate;
• Mechanical dewatering unit for sludge No. 3;
• Evaporation unit:
• First stage – evaporation with production of a concentrated product in the form of a liquid salt concentrate;
• Second stage – further evaporation of the salt concentrate from the first stage to obtain a salt suspension;
• Third stage – centrifugation (separation of crystalline salts from the liquid phase, obtaining waste with moisture content up to 40%).
