Single grade reverse osmosis

Reverse osmosis principle

  RO (Reverse Osmosis) referred to the RO, the external pressure, so that some components of the solution selectively through, so as to achieve desalination, purification or concentration of a practical technology for separation purposes. With water treatment works, it can remove the vast majority of ions in water, can also remove the fine particles of water, bacteria and organic matter and other impurities. Is advanced, economical means of water treatment equipment. The reverse osmosis process is the use of high-pressure pump to the high salt content of water pressure continuously pumped to the RO plant, the RO unit contains a reverse osmosis membrane elements and pressure vessels, water is divided into low-salt permeate containing high salt concentrate. The water supply controlled by a regulating valve into the proportion of concentrate and permeate.

Reverse osmosis (RO) technical characteristics

1.The components are imported or domestic high-quality products, advanced technology;
2, The overall level of high quality and reliable;
3, The high degree of automation, the case of failure to immediately stop the automatic protection function;
4, The desalination rate, up to 99% or more;
5, High efficiency, low noise imported good pump, reduces operation noise;
6, To reduce energy consumption, thereby reducing operating costs;
7, Reasonable structure, small occupation area, more than 30% space savings than conventional methods;
8, The use of advanced membrane protection system, equipment parking, in addition to the salt water flush automatically membrane surface contaminants, to prevent the structure and extend membrane life;
9, No wearing parts, without a lot of maintenance, long-term continuous operation;
10 Water quantity and quality of equipment in accordance with the requirements, use of professional software design, to achieve the best value for money.

Reverse osmosis devices rely on the membrane on both sides of the static pressure difference as the driving force, allowing only the solvent (usually water) through the interception membrane separation of ionic substances on the removal efficiency of various ions in water are shown in Table 2-18 -1
