Introduction to pure water equipment

Pure water equipment, refers to the water in the conductive medium is almost completely removed, while the dissociation of gas, colloid and organic matter (including bacteria) also removed to a very low degree of water. Its conductivity is generally 10uS / cm or less, salt content <0.1㎎ / L.

Working principle: The system for the domestic market is more mature technology, the operation of a convenient water system, the use of physical reactions and chemical reactions combined with the principle that the world's most advanced reverse osmosis system, and gradually improve the water quality; the company based on the user in the production With the water on the water requirements, the use of different treatment methods, the best cost-effective, and ultimately to achieve the standard of production water.replacement filter.

Process overview

1、Pretreatment system

Pretreatment is mainly to remove organic matter in water, suspended solids, colloids and residual chlorine, etc., to ensure that RO can work properly. The process uses multi-media filtration, activated carbon adsorption, reduce RO work to produce dirt and algae growth and microbial contamination and oxidants.

Pretreatment system includes: the original water tank, the original water pump, multi-media filter, activated carbon filter, soften the filter.

Raw water tank: Raw water first flows into the original water tank. The original water tank on the supply of raw water to play a buffer role, coordination of raw water supply and raw water pump input. When the supply of raw water exceeds the original water pump, the original water tank is full, and the raw water supply is stopped by the liquid level control of the original water tank. When the raw water supply is less than the original water pump, the original water tank empty, the original pump to stop running, play a role in protecting the original pump.

The original water pump: system configuration stainless steel water pump, used to pressurize the raw water, for the pretreatment system to provide power source, the pump material for the stainless steel. The pump has the characteristics of small size, high efficiency, low noise and so on.

Sand filter: The system is suspended in the raw water, the original water pump: the system configuration stainless steel water pump, used to pressurize the raw water, the pretreatment system to provide power source, the pump material for the stainless steel. The pump has the characteristics of small size, high efficiency, low noise and so on.

Particles and colloids and other substances to be removed, while the original water turbidity, color play a role in reducing it, it can filter out the raw water to bring particles, algae and other visible things. Multi-media filter is an advanced micro-flocculation filter, the company provides multi-media filter with different materials, multi-layer filter media, can filter out impurities in the water, to ensure that the SDI value of not more than 4, after the Level RO strong protective screen. (Oxide, turbidity, particulate matter, etc.), with low cost, operation and maintenance, easy management and other characteristics, especially in the reduction of raw water turbidity, pollution index, etc., can be better to remove suspended solids or insoluble particles Aspect has a very good effect.

Activated carbon filter: Activated carbon process in the field of water treatment occupies a very important position, is the water depth of the indispensable process, it has some of the special effects of other water treatment process can not be replaced.

(1)Decolorization: Removes chromaticity from iron, manganese and plant decomposition products or organic contaminants.

(2)Dechlorination: Removes the odor caused by residual chlorine.

(3)Removal of organic matter: Removal of trace contaminants in water such as pesticides, pesticides, chlorinated hydrocarbons, aromatic compounds, and BOD and COD, which can not be removed by conventional processes due to water pollution.

(4)Removal of organic chlorine: Removal of "three-in" substances such as THMS produced by pre-oxidizing agents and disinfectants (such as chlorine) before the raw water purification process and the tap water are shipped. Some analysis shows that the "three" matter THTS in tap water accounts for more than half, and effective removal is critical to improve water quality.

(5)Removal of ammonia and nitrite: activated carbon can effectively remove ammonia and nitrite.

(6)Remove the remaining chlorine or oxidant, protect the ultrafiltration, reverse osmosis membrane.

In addition, it can deodorize, remove the heavy metal ions in the water (such as mercury, chromium plasma), synthetic detergents and radioactive substances.

Softener: softened water equipment, as the name suggests to reduce the water hardness of the equipment, mainly in addition to water in the water, magnesium, softened water equipment in the process of softening water, can not reduce the total salt content of water.

(1)Working principle: automatic sodium ion exchange using ion exchange principle, remove the water calcium, magnesium and other fouling ions. When the raw water containing the hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water are replaced with the sodium ions adsorbed by the resin, the resin adsorbs calcium and magnesium ions, and the sodium ions enter the water, so that the fluid flows out of the exchanger The water is to remove the hardness of softened water.

When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated, the regeneration process is to use salt salt in the salt water rinse resin layer, the resin on the hardness of the ions and then replaced, with the regeneration of waste discharged from the tank, the resin But also restored the softening exchange function.

Since the hardness of water is mainly formed by calcium and magnesium, and because the hardness of water is mainly composed of calcium, magnesium and sodium ion exchange softening principle is the raw water through the sodium cation exchange resin, the water hardness components Ca2 +, Mg2 + and Na + in the resin exchange, so as to absorb the water Ca2 +, Mg2 +, so that the water softened. Such as RNa on behalf of sodium resin, the exchange process is as follows:

2RNa + Ca2+ = R2Ca + 2Na+ 

2RNa + Mg2+ = R2Mg + 2Na+ 

That is, water through the sodium ion exchanger, the water Ca +, Mg + is replaced by Na +. General control valve running process: running, backwashing, salt, slow wash, salt tank replenishment, is washing.

2、Reverse osmosis system

Introduction to reverse osmosis technology

Reverse osmosis is NASA's multinational scientist, with the support of the government, spending billions of dollars, after years of research.

Reverse osmosis was originally used to recycle the space people's life water, so that it can be re-drinking, so that spacecraft do not have to carry a lot of drinking water, so called space technology. It is also known as "space water".

The principle of reverse osmosis is to apply more than the pressure on the raw water to cause the water molecules to reverse osmosis from the high concentration side to the low concentration side. As the reverse osmosis of the hole is far less than the case of drugs and bacteria hundreds of times or even thousands of times, so a variety of viruses, bacteria, heavy metals, solid soluble matter, pollution of organic matter, calcium and magnesium ions can not pass through the reverse osmosis membrane, Water softening the purpose of purification. It is the advent of human development history of a very significant water treatment technology revolution. At present, the world is widely used in this technology for desalination, industrial water production and drinking water purification and so on, as well as astronaut waste water recycling are used in this method is in vitro high-tech artificial kidney.

Application of Reverse Osmosis Technology

Reverse osmosis technology is based on the role of osmotic pressure than the solution, according to other substances can not pass through the semipermeable membrane and these substances and water separated. The membrane diameter of the reverse osmosis membrane is very small, so it is possible to effectively remove dissolved salts, colloids, microorganisms, organic substances and the like in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and simple operation. 

Reverse osmosis membrane is widely used in electric power, petrochemical, steel, electronics, medicine, food and beverage, municipal and environmental protection and other fields, in the sea and brackish water desalination, boiler feed water, industrial water, purified water and electronic grade ultrapure water Preparation, drinking pure water production, wastewater treatment and special separation process plays an important role.

Cartridge Filter Housing:After the front of the quartz filter Housing, activated carbon filter Housing and softening filter Housing, the large particles of raw water suspended solids has been basically removed, and some small particles suspended solids are not removed. Where a microfiltration is performed again to remove suspended solids above 5 μm to protect the RO membrane from clogging.At the same time, some activated carbon and cationic resin foam is also trapped outside the reverse osmosis system. Fine filter inlet and outlet pressure indicator, when the pressure increases to the set value when the replacement filter cartridge.

High pressure pump: high pressure pump reverse osmosis equipment main power equipment, high pressure pump should be set to high overheat protection, pump before and after the set of low, high voltage protection switch. When the high pressure pump inlet pressure below the set value, the high pressure pump outage to protect the high pressure pump, when the high pressure pump outlet pressure is higher than the set value, the high pressure pump outage to protect the reverse osmosis membrane.

Reverse osmosis device: reverse osmosis device is the part of the project pre-desalted heart, the reverse osmosis treatment of water, can remove the vast majority of inorganic salts, organic matter, microorganisms and so on. The design is reasonable or not directly related to the project investment costs, the entire system operating economic efficiency, service life, reliable operation and simplicity. Reverse osmosis membranes are the world's most advanced low-pressure composite membrane, a single desalination rate of 99%. In the design, should take into account the equipment of energy saving, operating pressure, membrane permeability, membrane desalination rate, the salt content of water and other factors.

As the raw water salinity is higher, in the process using a reverse osmosis device, the main removal of water in most of the yin, cations, organic matter, heat and bacteria. Reverse osmosis (RO) a desalination system by the RO membrane module device, high pressure pump, RO cleaning device, control and instrumentation and other components.

Reverse osmosis is a selective membrane through the use of (semi-permeable) membrane function, pressure-driven membrane separation technology, membrane components from the reverse osmosis membrane diversion cloth and the central tube made of a number of RO The membrane element is housed in a stainless steel pressure vessel to form an RO assembly. This device is the key to desalination system, mature process design, reasonable control, operation and management, directly determines the system of normal and stable operation. And the relationship between the life of the reverse osmosis membrane, the reverse osmosis treatment of the water, remove the vast majority of inorganic salts and almost all organic matter, microorganisms (bacteria, heat, etc.) to ensure that the system of water products, high quality, high quality.

After the completion of the pretreatment of the effluent from the sediment density index SDI tester monitoring, when the SDI value <4, you can enter the RO system, pressurized by the high pressure pump into the reverse osmosis system, RO part of the water (desalted water) to Storage tank, and the other part of the pipeline after the collection of concentrated water (mainly containing salt, mechanical impurities, colloids, organic matter, etc.) with a small part of the water through the water into the sewer.

3、UV sterilization system

UV sterilization is through the ultraviolet radiation, destruction and change the microbial DNA (deoxyribonucleic acid) structure, so that bacteria immediately died or can not reproduce the progeny, to achieve the purpose of sterilization. Truly sterilization is UVC UV, because C-band UV is easily absorbed by the body's DNA, especially about 253.7nm UV. UV sterilization is a purely physical disinfection method, with a simple and convenient, broad spectrum efficient, no secondary pollution, easy management and automation and so on.UV sterilizer with uniform water flow, no dead ends, light conditions, sterilization thoroughly, low energy consumption, flexible installation and other characteristics, the main material using stainless steel, no metal ion infection problem, the product structure for the closed container quartz tube type, Equipped with electrical control device.
