Water treatment and wastewater treatment systems

The project implemented:

1. Development of design and detailed documentation
2. Production and complete supply of equipment

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
4. Installation and supervision of installation works
5. Commissioning works
6. Personnel training

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%).

Scope of supply:

1. Pre-project surveys
2. Development of basic and detailed engineering
3. Process and general design
4. Development and implementation of APCS (Automated Process Control System)
5. Supply of process equipment
6. Supervision of installation works
7. Commissioning works

The complete filtration unit is supplied to the Omsk Refinery within the framework of the project to reduce the concentration of harmful substances in the plant’s industrial wastewater.

Thanks to multi-stage treatment, the efficiency of wastewater purification at the Omsk Refinery will increase to 99.9%.

Scope of supply:

• Complete supply of equipment
• Commissioning works

The installations are equipped with mechanical vapor recompression (MVR) and forced circulation technologies, which contribute to resource saving, improve energy efficiency and profitability of production, and ensure environmental safety.

The equipment was implemented within the framework of a project for landfill reclamation and industrial waste processing.

Scope of supply:

1. Development of working design documentation
2. Manufacturing and complete supply of equipment
3. Installation works
4. Commissioning works

Assembly of the station at the ZAVKOM-ENGINEERING site

Delivery of the station to the Customer’s site

Currently, equipment is being manufactured, power and control cabinets are being assembled within the framework of a project with JSC "Ion exchange technologies" for JSC "Gazpromneft ONPZ".

Within the framework of this project, implemented / planned:

1. the technology,
2. working design documentation was developed,
3. the equipment was completed,
4. the equipment was manufactured and supplied,
5. installation supervision and commissioning were carried out.

The local wastewater treatment plant is part of the thermoplastic elastomer production at JSC "Voronezhsintezkauchuk" and allows purification of wastewater from lithium ions to a level below 0.08 ppm, ensuring environmental safety of the main production for the entire region.

Scope of supply:

1. Technology development
2. Development of working design documentation
3. Manufacturing and complete supply of equipment
4. Supervision of installation works
5. Commissioning works
