EDI ultrapure water device

Product introduction: fully meet your requirements for the use of pure water

 

The "superior" pure water machine can directly purify city tap water, groundwater, surface water into three-level water, and the real-color LCD screen can be set to arbitrarily set timing, quantitative, qualitative water fetching, historical data query, and continuous electric desalination EDI-Electrodeionization) system uses the quality of the effluent from reverse osmosis as raw water. The new EDI technology can replace the traditional ion exchange device. It can continuously produce ultra-pure water of 10-18MΩ.cm. A cost revolution of the water treatment industry, its biggest feature is the use of electricity instead of acid and alkali to regenerate the resin, so it is very economical and practical, and can obtain stable pure water with limited energy consumption. It has the advantages of stable effluent water quality, low operating cost, convenient operation and management, and small area. Since the industrialization of EDI technology in 1996, it has been widely used in industrial fields such as medicine, electronics, electricity, and surface cleaning, and has achieved a good economic Benefits, favored by the majority of users, the development of water treatment technology has entered a brand-new stage; optional USP interface and micro printer can print all the data for one year. With source water<150PPM, the life of consumables can reach 1 -2 years, product design is fully automatic control, no need to manually clean the filter.

 

Process introduction: This process is divided into source water purification system, reverse osmosis system, rear ultraviolet sterilization system, microfiltration device system, etc.

 

Pre-processing part:

 

844-3 Full-automatic chlorine, calcium and magnesium ion removal system

 

Pretreatment. At present, we have three types of pretreatment filters: stainless steel filter, glass steel filter and carbon steel lined rubber filter. There are three types of preprocessing filtering:

 

1, multi-media filtration (except particulate matter and heavy metals)

 

2, organic matter filtration;

 

3. Calcium removal, magnesium ion filtration and other three parts; the entire set of soft water system can use "Runxin" full-automatic multi-function control valve for full-automatic automatic control, according to the set time, the filter material in the filter tank is backwashed and positive Flushing is achieved without manual control to reduce personnel labor, ensure normal operation of the post-reverse osmosis system, increase the desalination rate of the reverse osmosis, and extend the life of the reverse osmosis.

 

Before the water is refined, preliminary treatment is carried out in advance, so as to obtain good results and improve water quality during the water refining. Water in nature has a large amount of impurities, such as sediment, clay, organic matter, microorganisms, mechanical impurities, etc. The existence of these impurities seriously affects the water quality and treatment effect of refined water, so some impurities must be reduced or Removal, which requires pretreatment.

 

First level: multi-media filter (quartz sand + manganese sand);

 

1), multi-media filter is mainly used to remove suspended matter, sediment and particulate impurities in water;

 

The main fillers are: high white sand 8-12 mesh / 10-20 / mesh / 20-40 mesh.

 

2), in addition to heavy metals:

 

The main filler is: natural manganese sand, (KDF filter material needs to be configured in special areas);

 

Principle of iron removal: Oxidation method is used to oxidize low-priced iron ions and low-manganese ions in water to high-valent iron ions and high-manganese;

 

3), calcium chlorite sulphite balls are made of natural raw materials such as nanometer stepless antibacterial and anti-mildew, calcium sulphite, with special characteristics and speedy process. The advantages of safety and wide application range can be widely used in the fields of domestic water treatment and industrial water treatment.

 

1. High efficiency: After testing, the calcium sulfite dechlorination ball has extremely high ability to remove residual chlorine and extremely fast reaction time. It can remove more than 99% of chlorine in 0.8 seconds, which is an ideal high-efficiency chlorine removal product.

 

2. Stability: It can be used safely and the effect is stable in a wide PH range and a temperature environment of 0-80 degrees Celsius.

 

3. Safety: Calcium sulfite balls are produced under strict technological conditions and have extremely low solubility in water. After testing by the Import and Export Inspection and Quarantine Bureau, the products are safe and reliable when used in drinking water products, and no heavy metals and other organic substances are released.

 

Calcium sulfite ball meets the standards of food additives in Japan and Europe. In Europe and other countries (INS number. International number of food additives 226) according to the evaluation report of JECFA (International Food Standards Committee Committee on Food Additives Contaminants), its ADI (Allowable daily intake) is 0.7mg / kg.

 

吸附 4. Adsorption: It can absorb impurities and odor in water at the same time.

 

Second stage: organic matter removal filter

 

YH-11 coconut shell water purification charcoal: Activated carbon mainly removes impurities such as macromolecular organics, colloids, odors, residual chlorine and other impurities in water. It has strong absorption capacity and can remove more than 90% on average. The residual chlorine is a strong oxidant, which has an oxidizing effect on the RO membrane, and must be limited to ≤0.1 mg / L. There are three types of activated carbon: round bar charcoal, amorphous shell charcoal and coconut shell charcoal.

 

Third level: filter for removing calcium and magnesium

 

Cationic resin softener, the principle of sodium ion exchange softening treatment: raw water is passed through a sodium-type cation exchange resin to exchange the hardness components Ca2 + and Mg2 + in the water with the Na + ions in the resin, thereby adsorbing Ca2 + and Mg2 + in the water to obtain water soften.

 

Effect: It is of positive significance to prevent scaling on the surface of reverse osmosis membrane, improve the working life and treatment effect of reverse osmosis, so softener is configured in the system. When the total hardness is less than 200mg / L CaCO3, no softener is needed. The best control method is automatic control.

Reverse osmosis purification system

 

RO (reverseosmosis) reverse osmosis technology is a membrane separation and filtration technology using pressure difference as the driving force. Originated from aerospace science and technology research in the United States in the 1960s. The RO reverse osmosis membrane has a pore size as small as nanometers (1 nanometer = 10-9 meters). Under a certain pressure, H20 molecules can pass through the RO membrane, while impurities such as inorganic salt ions, organic matter, colloids, bacteria, and heat sources in the source water cannot. Through the RO membrane, the pure water that is permeable and concentrated water that is impermeable are strictly separated;

 

RO membrane can remove 99% of high-valent ions, colloidal bacteria and organic matter (including heat source) with molecular weight greater than 300Dalton, and 90-95% of low-priced ions (NA, K0). When the source water conductivity is<350μs / cm. The conductivity of RO pure water is usually <= 5μs / cm. It meets the national standard for three-level water use in the real room. The reverse osmosis method is the most economical method to achieve 90-95% impurity removal rate. The process is through two-stage reverse osmosis Treatment (the first reverse osmosis desalination rate can reach 2-10 μs / cm, the second reverse osmosis desalination rate can reach 1 μs / cm). It is also the best pretreatment method for ultrapure water systems.
