Services of Water Technologies and Service Division:
Usage: for water pre-treatment (clarification) and wastewater purification.
Application fields:
Operating principle:
In principle, dynamic water clarification technology is based on contact coagulation and pressure filtration through a layer of floating load. When processing source water, two chemicals are sequentially dosed into the water - the coagulant is dosed to increase the purification degree, and the flocculant is added to form pollutant flakes, which will be subsequently retained in the floating load layer.
Periodic water-air flushing is provided to remove accumulated pollutants from resin charge.
Advantages:
Dimensional | Technological | Operational | Economic |
---|---|---|---|
Low metal intensity Minimal internal volume Convenient modular structure Minimal construction footprint |
Wide range of regulation of hydraulic load Low internal needs for wash wastewater discharge (3-6 times lower than for ultrafiltration) DYCLAR™ technology doesn't require water heating Consistent quality of purified water with significant deterioration of source water quality. DYCLAR™ combines two pre-treatment stages: clarification and mechanical treatment. |
Simple and traditional for Easy automation and Additional level of Visual control of |
Low operating costs (25-40% lower than for the foreign equivalents) Service lifetime of filtering materials - 20 years Service lifetime of the main equipment DYCLAR™ - over 30 years |
Usage:with low concentration of pollutants in the solution; at the last stages of water treatment; in water treatment systems to obtain water of high purity.
Type of ion exchange | Advantages |
---|---|
Softening - removing of hardness salts from ion-exchange resin based water. |
Economy: counterflow ion exchange technology allows to reduce the main equipment configuration and consumption of chemicals for regeneration by 2-3 times, reduce internal need for reactants by 2-3 times, as well as to use ion exchange resins of any manufacturer. High filtration rate (about 30-40 m3/h) reducing the number of installed equipment and feed volume. Wide capacity (10-140%) and maneuverability (when the filter is stopped, it can be started without regeneration operations). |
Desalination - removal of cations and anions and water-soluble salts. |
|
Fine desalination - obtaining finely desalinated water relative to separate Н-ОН - or Н-ОН-Н-filtration of silica and salt-content in finely desalinated water due to no counter-ionic effect in the mixed layer of ion exchangers. |
Usage: production of finely purified water and desalinated water for energy, microelectronics, food industry, pharmaceuticals.
Advantages of reverse osmosis technology:
Usage: allows to replace the traditional ion exchange at the finishing stage and consistently obtain high quality water (with electrical resistance above 10 MΩ · cm) without using chemicals.
Advantages of electric deionization:
The company carried out a turnkey project (including design, supply, installation and commissioning) implementation of a source water clarification unit for sulfuric acid production plant. The unit is based on a unique dynamic clarification technology DyClar.
The quality of clarified water corresponds to the specification requirements.
The company carried out an EPCM project on the construction of DyClar technology based mine water treatment plant for Kostromskaya mine. The plant capacity is 9720 m3/day.
Re-treatment of waste mine water to the effluent discharge standards (EDS) with water consumption of 575 m³/h.
The company carried out a turnkey project (design, supply, installation and commissioning) implementation of DyClar technology based unit for water clarification. The transition from tap water to river water for desalination plants (boiler feed water) and softening (heating network feed water) was performed. The plant capacity is 16 440 m³/day.
The quality of clarified water corresponds to the specification requirements. Transition from mine tap water to river water contributing to a multiple reduction of operating costs.
The modular desalination plant replacement project at the metallurgical plant is implemented. By early 2019 the specialists of Water Technologies and Services Division designed and launched two counterflow ion exchange plants with a capacity of 150 m3/h each. The delivery of third plant is planned.
Minimization of the amount of highly mineralized wastewater and reduction of the total amount of drains of the enterprise.
The company has gained the first experience in supplying and launching a reverse osmosis plant for water treatment. The plant was launched in the first week of November, 2016.
Achievement of water quality standards.
Equipment for industrial effluents and rainwater treatment was supplied; DYCLAR dynamic water clarification technology was implemented.
Reduction of suspended substance content in treated effluents by 97-99%.
Reduction of iron content by 90-97%.
