summary

The rainwater descends and comes into contact with the atmospheric CO gas to become carbonated water.
This carbonated water passes through the various bedrocks, it would be turned into a light water forming sclaes on boiler or mechanic system or pipe by dissolving the mineral material The water softening system is a system that turns calcium (Ca ++) and magnesium (Mg ++), which are the main components of the scale among mineral salts in the water, into soften water by using strong acid cation exchange resin.

summary

When a semi-permeable membrane is installed between two solutions of different concentrations, the solution moves from the lower concentration side to the higher concentration side. This phenomenon is referred to as osmotic phenomenon.
Applying high pressure exceeding osmotic pressure to artificially concentrated solution and inducing flow in opposite direction through specially manufactured membrane, reverse osmosis phenomenon appears. And, it is a water process system that removes dissolved minerals, minerals, salts, organic matter and fine particles up to 99% by applying this principle to the water.

summary

The ultrafiltration membrane filtration method generally has a pore size of 0.1 to 0.001 μm and is hollow with a hollow center. It is a system that can separate materials dissolved or dispersed in liquid by particle size. This is an intermediate between the microfiltration (M/F) and the reverse osmosis (R/O) method. It has excellent ability to remove fine particles and microorganisms (algae, Escherichia coli and common bacteria) except ionic substances in solution. It is possible to separate, concentrate and purify only specific substances in a solution in which a polymer substance and a low molecular substance are mixed with permeability. This is the greatest advantage of the ultrafiltration membrane filtration system.

summary

The internal structure and regeneration method are relatively simple compared to the honeycomb pure water system, and the double-phase pure water production system is suitable when the number of bicarbonate ions (HCO3-) in the raw water is large.
When the substitution capacity reaches saturation, the cation is regenerated with 5-10% hydrochloric acid (HCI) and the anion is regenerated with caustic soda (NaOH) with 3-7% and can be used semi-permanently.

summary

The mixed bed pure water producing system is a system that may remove electrolyte in the water to the minimum because it results that cation exchange resin and the anion exchange resin come into contact countless if it puts the strong acidic cation exchange resin of the H type and the strongly basic anion exchange resin of the OH type by mixing them and passes the raw water through.
This mixed bed pure water system removes all of strong anions such as Na, K, NH4, Ca, Mg, and Fe and anions such as Cl, So4 and No3 and removes all weak acids such as carbonic acid, acid, hydrogen sulfide, free chlorine, it can remove almost all with simple control.
When the capacity of the ion exchange resin is limited, the cation can be regenerated with 5 ~ 10% hydrochloric acid (HCl) and the anion with caustic soda (NaOH) 3 ~ 7%, and it may be used semi-permanently

summary

All microorganisms contain Proteins and Nucleic Acids in their structure. When a certain amount of ultraviolet rays are absorbed, it destroys the DNA of the microorganism itself or remarkably paralyzes its function, so that the microorganism can not be fissioned. By using this unique function, it is a system that shows 99.9% sterilization effect against all kinds of bacteria and fungi.

summary

The EDI System is a system that removes ions by an electrical method and replaces the function of ion exchange resin for regeneration in existing ultrapure water facilities.
Ion exchange resin is inserted into the diaphragm space of the electrodialysis membrane device. When the direct current is applied when the water passes through it, the ion is drawn to the electrode side and removed. Therefore, the ionic substance in the water can be removed without using the chemical agent An environmentally friendly water treatment system.

summary

The central water purification system is intended to raise the level of water related facilities by supplying domestic water such as stable drinking water and soft spring water after central water treatment of the water supply to apartments and public buildings. It also has the effect of extending the efficiency and lifetime of the related construction ratio, helping to improve the quality of the whole building. It has been recognized as a technological power in many fields by obtaining a utility model.

summary

Swimming pool should provide a comfortable environment for the user by always maintaining the drinking water quality that does not harm even the elderly or children. However, since it is used by many people, impurities such as suntan oil, body lotion, chemicals such as body lotion, The foreign substances in the water drop the condition of the water quality and increase the pollution due to the corruption of the foreign matter, so must fully manage water quality.
The pool water purification system removes impurities and foreign substances according to the backwashing and washing process and recirculates the contaminated water in the backwashing process through another filtration system, thereby contributing to water waste and energy saving effect due to discharge of sewage water It's possible.

summary

In modern society, demand for water is continuously increasing due to population increase, improvement of water supply rate, and improvement of living standards.
However, despite the continuous efforts to secure water resources, difficulties in dam construction due to various environmental conservation measures, It is necessary to take measures from a long-term point of view due to pollution of water resources caused by environmental destruction.
The rain water purification system is intended to reduce economic costs and reduce environmental pollution by reusing rainwater that has been abandoned so far and storing it in a separate water storage tank and then treating it as a drinking water such as toilet water or landscaping water, There is little pollutant such as organic matter or insoluble matter, and it is easy to treat. Especially, there is a need for large-sized buildings such as office buildings and apartments where there is a lack of water for daily use.

summary

Most groundwater is formed by the gathering of rainwater and snow melted water into the soil and flows through the open gaps between the rocks below the earth's surface where the plants grow.
Like surface water, it is widely used as agriculture, industry, home and other water. It is often called the hidden sea because it is a very important water source in areas where there is a shortage of water supply or where there is absolutely lack of surface water.
However, groundwater is contaminated by food waste left in the household, wastewater such as household garbage and manure coming from the house, pesticides, etc., and serious human health problems caused by waterborne diseases (dysentery, typhoid, cholera etc.) And the necessity of water purification system for ground water is getting more and more.

summary

AOP stands for Advanced Oxidation Process, which means Advanced Oxidation Process.
Commonly known oxidizers include ozone, chlorine (chlorine gas, chlorine dioxide, sodium hypochlorite), hydrogen peroxide (H2O2), potassium permanganate (KMnO4) and potassium dichromate (K2Cr2O7), and it is widely used for sterilization of various water treatment sites, decolorization, decomposition of organic matter, and reagents for water quality analysis.
However, oxidation agents other than ozone have problems such as leaving residues in water or forming other compounds when used for water treatment, causing secondary pollution and destroying the ecosystem of the discharge area. In the fields of water purification and waste water treatment, advanced oxidation methods are required which maximize the performance (oxidizing power) as an oxidizing agent and do not form secondary pollution or residual substances in the water after treatment, and AOP system is the most suitable thing to be applied to this request.

summary

It is a device that continuously injects the medicine stored in the chemical tank at a constant pressure by using a chemical metering pump.
The flow meter detects the flow rate of the water and adjusts the concentration of the chemical and the amount of the chemical constantly by proportional control.
It automatically injects the quantitative amount and the device which continuously detects the flow of the flow rate or injects the quantity by the tank level signal and other devices.
