2000Lph water pretreatment filter with ro and edi

The ultrafiltration systems are usually operated in a pressure range of 10 to 50 psig and they remove particles in size down to as small as 0.02 µm. Typical flux (rate of finished water permeate per unit membrane surface area) for UF system is 10-100 gallons per square foot per day (gfd).

Our membrane filtration system uses advanced hollow fiber or ceramic technologies which operate in the outside-in or inside-out direction of flow. Given the small membrane pore sizes used with these technologies, fouling due to deposition of organic and inorganic compounds on the membrane may occur if the ultrafiltration system is not properly designed and operated. Therefore, we use automated backwashing, air scour and chemical flushing processes to restrict the rate of membrane fouling within acceptable limits. Chemical cleaning is employed once the maximum transmembrane pressure has been reached. Typical cleaning agents utilized include acids, caustic, surfactants, enzymes and certain oxidants, depending upon membrane material and fouling type.

EDI (Electrodeionization) is a revolutionary water treatment technology; it is a membrane filtration and desalination technology that skillfully combined the electrodialysis technology and ion exchange technology together, which is high-tech, green and eco-friendly technology.

EDI module uses the RO outlet water as feed water. The resistivity of RO outlet water is normally 40-2μS/cm (25℃), and the resistivity of EDI outlet water can normally reach 18MΩ.cm (25℃). According to the application of deionization water and the setup of the system, EDI outlet water can meet the requirements for resistivity of 1-18.2MΩ.cm (25℃).

The advantages of EDI equipment are continual water production, no acid and alkali regeneration, unattended operation, etc. It is gradually replacing the mix bed as the fine treatment equipment. Due to its environmentally friendliness and ease of use, EDI equipment has been accepted by more and more people and widely used in pharmaceutical, electronic, electricity, and chemical industry. Its existence is a revolutionary progress of water treatment equipment, which marked the water treatment industry finally entered into green industry.

Reverse osmosis systems are used to purify water and remove salts and other impurities from tap and brackish water. It is also capable of rejecting bacteria, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 dalton. Our largest tap and brackish water units can come standard with media pre-filters, chemical dosing, and antiscalant. These systems are usually customized to fit individual customer and water application needs

The above machine which we supply it to you, we can give you one years after sales warranty, we can also send our engineer to you factory to install this equipment and train your staff, but the Buyer should pay the round air ticket cost and arrange the hotel accommodation as well as the means for Seller’s engineer. We will send some free set of spare parts for you change it.
