DI water system working principle:

Reverse osmosis is the most sophisticated liquid membrane separation technology, applied operating pressure in the water side (concentrated solution) to overcome the natural osmotic pressure, when the operating pressure is higher than the natural osmotic pressure, the water molecules natural penetrate flow direction will be reversed, water (concentrated solution) molecules become purified through the reverse osmosis membrane; reverse osmosis equipment can stop all soluble salts of organic and molecular weight greater than 100, but allows water molecules through the composite reverse osmosis membrane, desalination rate is typically greater than 98%, they are widely used in industrial pure water, plating machine area, electroplating field, and electronics, drinking water production, boiler feed water and other process. Before using ion exchanging, using DI water system can greatly reduce discharge volume of water and waste water.

Reverse osmosis plant process

Ultra-pure water is a kind of water that normally pure water equipment generally difficult to achieve the degree, usually using pre-treatment, reverse osmosis machine, ultra-pure water treatment equipment as well as post-processing step total 4 steps, multi-stages of filtration, high-performance ion exchange (polished), super filer machine, UV lamp, in addition to a variety of processing methods such as TOC vice or other something likes, the resistivity reachability 18.25MΩ*cm. These are steps of reverse osmosis plant.

Reverse osmosis plant technical processes roughly divided into the following:

1, Using the traditional methods of water treatment ion exchange resin manufacturing ultra-pure water, the basic process:

Raw water → Sand charcoal filter → Precision filter → Anode bed → Cathode bed → Mixing bed (Duplicated) → Pure water tank → Pure water pump → Rear set precision filter pure water pump → Water outlet.

2, By way of a reverse osmosis plant water treatment equipment combined with ion exchange equipment, the basic process:

Raw water → Sand charcoal filter → Precision filter → Reverse osmosis plant → Pure water tank → Mixing bed (Duplicated) → Super pure water tank → Super pure water pump → Rear set precision filter pure water pump → Water outlet.

3, Using reverse osmosis water treatment equipment together with electrodeionization (EDI) device, which is a preparation of ultra-pure water the latest technology, also is an environmentally, economical, potential development of ultra-pure water process, the basic process as following:

Raw water → Sand charcoal filter → Precision filter → Reverse osmosis machine → Electrodeionization (EDI) → Ultra-Pure water tank → Ultra-Pure water pump → Rear set precision filter pure water pump → Water outlet.

All these three industry use pure water treatment machine is currently basically used for electrical industrial and plating area. The rest of pure water treatment process, mostly based on the basis of the above three basic processes with different combinations of derivatives from.

Ultrapure water treatment equipment technology advantages and disadvantages are listed below:

1, The first method of an ion exchange resin has the advantage that a small initial investment, less space occupied, but the disadvantage is the need for frequent regeneration of ions, acid alkaline consuming a lot, and there is some damage to the environment.
2, The second on a pre-matched of reverse osmosis plant, ion exchange equipment, which is characterized by initial investment higher than ion exchanging method, but the ion exchanging device regeneration cycle is relatively longer than the 1th method, acid-consuming much less than simply using ion resin exchanging. But also there are still some destructive to environment.
3, The third method of reverse osmosis machine for pre-treatment then together with electrodeionization (EDI) system, which is currently the most economical system for producing ultra-pure water, and also the most environmentally friendly ultra-pure water technology, without using acid regeneration still can continuous preparation of ultra-pure water, nothing damaging to the environment.

Deionized water system is a water treatment device which adopts pretreatment, reverse osmosis technology, post-processing and purification methods, which make the conductive medium is almost complete removal in water, also remove the not dissociation colloidal substances, gases and organic compounds to a very low level. Deionized water system, also known as pure water device, pure water equipment, ultra-pure water meter, pure water systems, laboratory pure water machine and so on.

With the progress of science and technology, pharmacopoeia preparation of legal pharmaceutical water were redefined. Its use is divided into different ranges: purified water, water for injection and sterile water for injection, it is first time change the distilled water to purified water, and definition of purifying water as “purified water by distillation, ion exchange, reverse osmosis or other suitable methods for medicinal water.” Deionized water system technology compared to traditional distillation method, pure water equipment based on reverse osmosis re-union of the latest electrodeionization (EDI) technology, which the new technology has obvious advantages and advanced.

High energy and high efficient deionized water system:

Mainly have multiple-stage distillation, high pressure centrifugal purification by distillation and fractional distillation several processes. All methods at 120 ℃ high temperature state, so it is absolute possible to obtain a completely sterile water. Thus, operation of such a considerable energy consumption; the same time because of the higher temperatures, there are an integral part of the device must withstand high temperature impact, leads to high manufacturing cost and maintenance cost of the equipment. Reverse osmosis technology combined with efficient ozone sterilization method, the whole system works in room temperature, low pressure, so that the equipment investment, operation and maintenance costs lower, and reliable energy: the membrane treatment method running cost is only 12-15% of distillation method, which is very economical, very competitive.

Deionized water system stable and reliable:

With the accelerated process of industrialization, a large and complex waste composition worldwide emissions, so that pollution is becoming increasingly serious, water pollution which is more severe than ever. Volatile organic pollutants because the boiling point of water vaporization temperature lower than most, if not treat this, in distillation process can easily enter into the generated water, while simple distillation methods can not effectively remove this. Must rely on activated carbon adsorption filtration methods, increase the instability of the system and water quality. Membrane process using multi-media filter pretreatment; Reverse osmosis membranes micro porous through formula works to ensure the removal of all large water ions, molecules, you can easily remove the larger molecular diameter of volatile organic contaminants, to ensure that organic matter indicators have reached a fundamental indicators Pharmacopoeia.

Deionized water system pretreatment system process description:

Pretreatment systems typically include quartz sand filters, activated carbon filters, softeners can be used if necessary, each of the devices can automatically ozone water backwash, automatic discharge;
Auxiliary equipment with automatic dosing system, ozone dosing system. Its main function: in different water conditions, making the two stage RO system to obtain a stable, qualified water quality.

2.4 Activated carbon adsorber

Activated carbon adsorber which used for adsorbing residual chlorine, odor andorganic substances and other harmful substances in raw water, reduce COD content, and to prevent the residual chlorine into RO device, to ensure safety using of membrane element in RO device. This system provided with a diameter of 1200mm vertical active carbon filter, while inside filter filled with activated carbon filter material, and the filter layer height occupy about 600-1200mm of tank. The active carbon adsorber backwashing time based on the blocking degree, which should backwash regularly, to wash away the blockage and broken parts or already reacted particles.
If there are only a certain amount of residual chlorine, but organic matter, smell or color content is minimal; then no need to replace active carbon on adsorber, only supplement wearing or carbon particles in residual chlorine action. If the organic matter content, smell or color is high content in water, generally in 2-3 years the active carbon need to be replaced, and the specific time depends on organic matter and color content, and smell degree in the water.
