Reverse osmosis concentrate polishing unit with a capacity of 900 kg/h

Implementation of an evaporation and crystallization unit for salt concentrate with subsequent dewatering in order to minimize and utilize salt sludge.

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 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 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
