Equipment overview:

Reverse osmosis (abbreviation: RO) is a membrane process that uses semi-permeable spiral membrane to separate and remove soluble solids, organic matter, colloidal substances and bacteria from water. It can effectively remove inorganic ions and small organic molecules of 0.1-2nm in water. Raw water is fed at a certain pressure and passed through the reverse osmosis membrane. The water passes through tiny holes in the membrane and is collected to obtain pure water. Impurities in the water are removed from the concentrator in the intercepting fluid. RO can remove more than 95% of dissolved solids in the water, more than 99% of organic matter and colloid, almost 100% of bacteria.

RO equipment is one of the most advanced equipment for making pure water in the world at present. It has low operating cost, economy, convenient operation and reliable operation. It is the preferred equipment for making pure water in the business. The production capacity of RO equipment is the value of raw water at 25℃, standard production condition. The change of water temperature and production conditions will affect the production capacity of the equipment.

Industrial reverse osmosis equipment need according to the different technological process of the actual demand of water, industry water use different standards, such as resistance is divided into 18 M Ω. Cm, 15 M Ω. Cm, to 10 M Ω. Cm, 2 M Ω. Cm, 0.5 M Ω. Standards such as cm, conductivity from 20 uS/cm to 0.1 uS/cm, so we need according to different standard of different pretreatment system, single stage two-stage reverse osmosis technology, the post-processing system (EDI electric desalination system, polishing system of the mixed bed, ultraviolet radiation sterilization, ozone generator, chlorine dioxide, etc.).

Operating conditions:

Based on the stable and safe operation of reverse osmosis system, the following inlet water requirements (outlet water requirements of pretreatment equipment) are proposed:

⑴ Pollution index SDI: ≤5

⑵ residual chlorine < 0.1mg/1(OT method)

⑶ Oxygen consumption < 2mg/1(Mn method)

⑷ Turbidity < 1.0NTU

⑸ ⑸ Longriel index LSI < 0

The water temperature range: 5 ~ 35℃

Advantages:

The removal of impurity range is wide, not only can remove the inorganic salt ions in water, but also can remove all kinds of organic impurities.

There is no phase change in the process of water separation, which has a high desalination rate (desalination rate up to 99.7%).

Large water production, small equipment volume, to achieve skid-mounted or according to the actual size of the site processing.

Low energy consumption, automatic operation, low investment cost.

Strong adaptability, wide application range, no environmental pollution and other advantages.

Scope of application:

Reverse osmosis equipment as the core of water desalination equipment, with pretreatment and follow-up desalination system has been widely used in the fields of water treatment, electronics, chemical, medicine, food, beverage, metallurgy and environmental protection.
