Reverse osmosis / RO Water Treatment Plant

详情

We adopt different equipment to produce pure water, mineral water etc. The main equipment of RO Water Treatment Plant are silica sand filter, active carbon filter, sodium ion exchanger, hollow fiber, RO( reverse osmosis), UV sterilizer, precision filter, ozone generator, water tank etc. The treatment capacity is 0.***0 ton/hour. It can effectively get rid of muddy organic matter, iron, manganese and oxide, filter suspended substance, colloid, remained oxygen of microorganism and some of heavy metal ion in the water, reduce the hardness of the water to make all specifications of the water quality fully meet the state fresh water standard of fresh drink water.

1. Customized capacity

The capacity complete depend on the customer demands.

2. Durable material

The material of water treatment plant is SUS **4.The material of ozone mixing tower tank is SUS **6, which is durable.

3. Best RO membrane

The RO membrane is American Hydecnme, which is famous. The RO membrane's desalting rate can reach *9.9%, removing over *9.9% ions. It has the features of simple structure, convenient operation and high technological level.

First stage pretreatment.(Sand filter)

The use of multi-medium quartz sand filters, main purpose is to remove the water contains sediment, manganese, rust, colloid material, mechanical impurities, suspended solids and other particles in the above *0UM of substances hazardous to health. The effluent turbidity is less than 0.5NTU, CODMN less than 1.5mg / L, iron content of less than 0.*5mg / L, SDI less than or equal to 5. Water filter is a kind of "physical - chemical" process, the water through granular materials when isolated filter water impurities and colloidal suspensions. Filter is an effective water purification and treatment of the main process in the preparation of pure water is an indispensable process.

Second stage pretreatment (Carbon filter)

Activated carbon filters used to remove the pigment in the water, smell, a large number of chemical and biological organisms, reducing the residual value of water and pesticide pollution and other harmful pollutants. The structure of activated carbon filters and quartz sand filters, the difference is placed inside the strong adsorption capacity of activated carbon for removal by the quartz sand filter without the filter out organic material, adsorption of residual chlorine in the water, using water more than less than or equal to chlorine 0.1ML/M3, SDI less than or equal to 4, are strong oxidants chlorine, there are various types of membrane damage, in particular, reverse osmosis membranes are more sensitive to chlorine. In addition, the activation process, the surface of activated carbon to form non-crystalline parts of some oxygen-containing functional groups, these functional groups can have a chemical adsorption of activated carbon catalytic oxidation of bad news, to restore the performance, can effectively remove a number of metal ions in water.

Third stage pretreatment (Resin softener)

Cationic resin used for water softening, primarily to remove hardness of water. The hardness of water is a major calcium (Ca2 +), magnesium (Mg2 +) ion composition, when containing the raw water hardness ions through the resin layer, the water of the Ca2 +, Mg2 + was exchanged resin adsorption, and other objects at the same time the quality of the release of sodium Na + ions flow from the softener in the water is removed from the softened water hardness ions. So as to effectively prevent the reverse osmosis membrane fouling.System can automatically recoil, and so is red.

Fourth stage pretreatment (Micron filter)

Particle size in water to remove fine particles, sand filters can remove very small colloidal particles in the water, so that the turbidity reached 1 degree, but still per milliliter of water for hundreds of thousands of particle size **5 microns colloidal particles, the pressure on this filter to remove water after the particle size of **0 microns or less in small particles, to further reduce the turbidity, to meet the next process of the water requirements of the protection of the next long-running processes.

RO system

Using reverse osmosis technology for desalination, reverse osmosis membrane was only 0.**1 micron pore size, can be harmful to remove dissolved solids and bacteria, viruses, etc., desalination rate of more than *9.6 percent, in line with national standards to produce pure water, the host section contains the security filter, high-pressure pump and reverse osmosis membrane, security filters for the fourth grade and above pre-treatment systems, high-pressure pump is the host of one of the core equipment for the reverse osmosis membrane elements to provide sufficient pressure to overcome the penetration resistance to pressure and run to meet the needs of a device to achieve the rated water.

Silica sand filter

It can remove the suspended solids and gluten particles in the water, thus reduce the turbidity of water.

Active carbon filter

It can remove the pigment, smell and a large number of biological organisms in the water

Soften the water.

Sodium ion exchanger

It can remove calcium and magnesium ions in the water, so as to soften the water.

Precision filter

It can ensure that the granularity of the water into reverse osmosis membrane is less than 0.1um.

Reverse Osmosis

The Reverse Osmosis device is an equipment to purify the saline water with the action of pressure difference of semi-permeable membrane. It is called reverse osmosis, as it is counter to natural penetration direction. Difference materials have different osmotic pressures.

The reverse osmosis can remove more than *7% of the soluble salt and above *9% of the colloid, microorganism, particles and organic materials, becoming the best first-choice choice equipment in the engineering of modern purified water, highly purified water and space water (super-purified water). The most highlighted features are low energy consumption, no pollution, simple technique, high-quality water and convenient operation and maintenance.

UV sterilize

It uses the UV to kill some bacteria that may also pass through the reverse osmosis system.

Ozone sterilizer

Some bacteria may not be killed by UV, the sterilizer uses ozone to kill those bacteria.
