Water treatment and desalination

The development of water treatment, purification, desalination technologies has become one of the urgent tasks in the modern world with its constantly rising needs for fresh clean water in both industrial and private sectors, and the lack of water treatment plants.

The market comprises three major sectors:

  • sea and salt water desalination for agricultural and private needs;
  • waste waters filtration and disinfection;
  • industrial use in oil, gas, mining: the sectors which need large amounts of water.

Water distillation and disinfection technologies

Ultrafiltration membranes (UF)

Ultrafiltration (UF) membranes have pores which allow to remove particles as large as 0.01 to 0.1 μm. In the process of filtration water flows through membranes which catch undissolved particles. This is used to prepare water for desalination, and is an effective microbiological barrier for tiny organisms.

Reverse osmosis

The reverse osmosis technology is based on pumping water under pressure through semipermeable membranes which allow water molecules to pass through and reject dissolved ionic species. As a result, the salt water is divided into so-called permeate, a flux practically free of salt, and a high salt concentration flux called brine.

At the present moment reverse osmosis is known to be the best water desalination technology available on the market. It is highly efficient, has lower energy consumption and needs less industrial space than equipment for thermo-cleaning.
