Pretreatment systems: reverse osmosis system is the key to long-term stable operation of the pretreatment, pretreatment of reverse osmosis quality determine not only the number of cleaning devices, and determines the life of reverse osmosis membrane elements.Pretreatment system solves is: membrane fouling of calcium and magnesium ions and iron and aluminum oxides, colloidal, suspended solid particles and organic matter in the obstruction, had to prevent oxidative damage of membrane material.The main by the multi-media filters, activated carbon filter, precision filter, dosing system components.The importance of monitoring in the pre-, multi-media filter and activated carbon filters designed to filter a lower flow velocity.
Quartz sand filter: design of a vertical cylinder with the filter, filled with fine quartz sand, the material of stainless steel, the total water system is set to 2.5 m3/hr.When the original water flow over the filter media layer filter, the filter slot on the sieve to play the role of suspended solids, suspended solids so easily trapped in the filter surface.When the filter surface withholding a certain amount of dirt, dirt membrane layer is formed, thus enhancing the filtering effect, to ensure that multi-media filter effluent SDI ≤ 4.Through the filter layer of water into the carbon filter.
Activated carbon filter: filled with refined activated carbon.This configuration is mainly used to granular activated carbon adsorption mechanism of adsorption of organic matter and chlorine, you can remove the gel residue, iron oxides, suspended solids and reduce the color, turbidity, to ensure the normal operation after the channel system.Activated carbon filter to ensure that the residual chlorine content in water ≤ 0.1ppm, SDI ≤ 4.
Softening system: removal of calcium and magnesium ions, the main purpose in order to prevent scale formation.Filled with sodium-based cation resin, the use of sodium ion exchange resin to remove the water scale model of the ion, such as Ca2 +, Ba2 +, Mg2 + and so on.Containing Ca2 +, Ba2 +, Mg2 + of the water softening system through the resin layer, the sodium ion exchange resin will and not the cation exchange reaction.Sodium ions are replaced out of resin and calcium and magnesium ion binding, carbonate and bicarbonate with the sodium ions to form sodium carbonate, sodium bicarbonate and other substances not easily scale to reduce the raw water hardness.The total amount of cation exchange resin is certain, after a certain time exchange resin saturated, saturated sodium chloride concentration of fluid needed to replace.
Security Filter: Set in the membrane before entering the RO system last security devices, to prevent large particles entering the water film, leading to membrane damage, ensure the normal operation of membrane systems.Precision filter is a vertical cylindrical device, filtering accuracy 5μm.
High-pressure pump: its main purpose is to make the reverse osmosis water reaches a certain pressure to reverse osmosis to take place, that is, the water molecules to overcome the osmotic pressure of fresh water through the reverse osmosis membrane layer, according to estimation of reverse osmosis water 1m3 /hr.
Reverse osmosis systems: reverse osmosis desalination system is in the pre-heart of the design of the mature, reasonable or not related to the life of reverse osmosis equipment and operating costs.The system components include high-pressure pump, reverse osmosis membrane module, automatic control and water quality monitoring.Membrane used Hyde's U.S. volume of polyamide composite membrane, can withstand high pressure and good chemical corrosion resistance, can remove most of the salt water, desalination rate of ≥ 99%.System design recovery rate of 65%.
