1. The mechanical filter is mainly used to remove rust, sediment, algae, suspended solids and other impurities in the water, reduce the turbidity of the water, make the turbidity of the effluent water less than 0.5NTU, CODMN less than 1.5mg/L, and iron content less than 0.05mg/ L, SDI≤5. It can be backwashed and forward washed at any time through the control valve to wash off the dirt on the surface, prevent it from clogging, and restore its filtering ability. Guiyang
2. Activated carbon filter Direct-approved activated carbon from the place of production of Guiyang living water purification equipment has strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, different colors, odors, and organic matter in the water. In order to kill possible diseases, it is necessary to take these considerations in advance. Since the reverse osmosis membrane is very sensitive to residual chlorine and organic matter, it is necessary to configure activated carbon to adsorb residual chlorine and organic matter, so that the residual chlorine in the effluent is ≤0.1mg/L, SDI ≤4, to meet the water supply requirements of reverse osmosis membranes. It can be backwashed by controlling the valve at any time to flush away the dirt on its surface, prevent it from clogging, and restore its processing capacity.
3. Anti-scaling device (softener)
A few mg/L of scale inhibitor can prevent the precipitation of hundreds of mg/L of calcium carbonate. The mechanism of action is that the long-chain anions generated by the scale inhibitor in water are easily adsorbed on the tiny calcium carbonate crystal grains. This replacement occurs on all the calcium ion layers dispersed in the water, thereby preventing the precipitation of calcium carbonate. It adopts American Milton Roy metering pump for automatic dosing, accurate measurement and reliable dosing. The dosage is about 3PPM. Pure water equipment, barreled pure water production equipment, purified water equipment, if necessary, the water quality can be tested accordingly, ultra-pure water machine, laboratory ultra-pure water machine, laboratory central pure water system is currently in pure water Most of the systems use scale inhibitors because they are more reliable than softeners and have low operating costs.
4. The security filter is equipped with a security filter before the high-pressure pump after pretreatment, which can prevent impurities and particles from entering the high-pressure pump and damage the high-pressure pump and reverse osmosis membrane. According to our company's many years of process design for reverse osmosis purified water equipment, the safety operation rules of pure water equipment, the complete set of system and the experience of membrane application technology, the various uses of pure water, so that we can have more guarantees The outer-loose inner-tight PP filter element (with frame, good strength), the water is filtered from the outside to the inside, which can extend the time that the filter element is blocked. Compression of the membrane module occurs, and the equipment needs to be cleaned regularly or irregularly during long-term use. The upper part of the pure water treatment system has an exhaust valve to prevent air from entering the pump and damage the pump. The lower part has a drain valve, which can be discharged at any time. Remove the trapped impurities.
5. Reverse osmosis device Reverse osmosis technology is currently a very mature desalination technology in the world, and it is also the most widely used and applicable water treatment process in the market. It can accurately filter out bacteria, viruses, metal ions, salts, pesticides and various carcinogens in the water. It has low working pressure, large water production, high salt rejection rate and easy maintenance. The design of automatic flushing device can extend its service life. Using two-stage reverse osmosis device to ensure that the conductivity of the water produced is less than 2us/cm. Guiyang domestic pure water equipment is directly approved by the spot
