Filtration and ION-exchange systems

VERYSELL Group offers systems and facilities for water filtration, sodium cycle water softening, decarbonization, ion-exchange demineralization.

Application areas:

  • Water treatment for cooling systems
  • Steam and hot-water boilers
  • Industrial processes, energy
  • Potable water preparation

Target industries:

• Oil and gas

• Food

• Energy

• Chemistry

• Textile

• Metallurgy

• Utilities

Filtration Systems

Filtration systems are designed to resolve the following issues:

● High concentration of iron, chlorine, organics, manganese and  hydrogen sulfide that affect taste of potable water and food

● Formation of scale of iron and manganese on tube walls, inside machinery and on heated surfaces that affects heat transfer, causes pipe overheating, increases energy and operational costs

● Poor textile dyeing caused by iron and manganese compounds in industrial water

Sodium Cycle Softening Units

As far as natural water is concerned, carbonate formation (scale) is often caused by cations of bivalent alkali-earth metals (mainly, Ca2+ and Mg2+). The higher is the concentration, the harder water is and the quicker scale forms on tube walls, inside machinery, in systems and devices that contact hot water.  This issue lowers equipment performance, causes overheating, failures and additional costs.

To resolve the problem, VERYSELL Group offers softening systems based on sodium cycle cation removal.

Decarbonization Units

Decarbonization is aimed at removing excessive free carbon dioxide from the water to prevent rusting of tube walls and machinery.  This technology has become widely applied for water treatment in heating, cooling systems, steam boilers, breweries, etc.

VERYSELL’s units rely on a selective technology based on weak acid cation resin. This substance is used to attract and retain cations that establish ionic bond with bicarbonates in water. Then the latter are replaced by hydrogen ions. The reaction involves calcium, magnesium and sodium  bicarbonates; СО2  by-gas is removed to the atmosphere, and the resulting ions Mg2+, Ca2+, Na+ remain in the water as  sulfates and chlorides.

Membrane technologies

VERYSELL Group offers a wide range of systems and solutions relying on modern membrane technologies for water treatment and filtration that can be applied for various purposes.

Ultrafiltration

Ultrafiltration is a low pressure (3-4 bar) membrane-based method mainly used for process liquid treatment. Held by a membrane,  suspended particles, large molecule organic compounds in solutions, and germs are then drained  as reject.

Industries & Application Areas:

• Oil and gas processing

• Energy

• Chemistry

• Metallurgy

• Utilities

Reverse Osmosis and Nanoscale Filtration

Reverse osmosis is applied for water demineralization and desalination. Depending on water, type of membranes and on the unit design,  this approach can yield the conversion rate of up to 80-99.7%.

Application areas:

• Desalination of low-mineralized water

• Desalination of sub-saline water

• Sea-water desalination
