Nutshell filter high hardness, wear resistance, compressive strength, resistance to pressure for 23.4KgF, chemical stability, not dissolved in acid, strong adsorption interception capability, the adsorption rate of 27-50% hydrophilic good Emery anti-oil filter, gravity g / cm31.25, slightly larger than the water filter lowest price Emery, filling a specific gravity of 0.85g / cm3, easy backwashing filter regeneration Emery Which is good, compared to other media, it The advantage is that the direct use of pre-filter backwash water, low operating cost, low backwash strength, (6.71 / S. m2), filter fast good (24-26 / n) results. Oilfield water containing not significant effect, removing up to 95% oil, oil dropped to 5mg / l or less of quartz sand is one of the most widely used filter is fast filter partner material. Quartz sand filter material currently used in two ways: one, the use of natural quartz ore, crushing, screening, washing processing, showed multiple prism, white and free of impurities, density, high mechanical strength, interception capability , good acid resistance and long life cycle; 2, the use of natural river sand, sea sand sub-screen together. The advantage of local materials, low cost; disadvantages are: erosion due to long-time water treatment Emery filter, reduced strength, wear rate, breakage rate, the use of short cycle, poor mechanical strength, which is the primary influence filtration rate factor. We also used a new technology purifying filter, extending the filter using 3-4 cycles, which is cost-effective compared with sea sand filter manufacturer emery _ Yu-tai water purification process (certified) _ Jinshan District Emery filter material provided by the Gongyi City Water Material Co., Ltd. Jinhua Yu Tai Branch. "Sales parent company produced fiber ball, PAC, polyacrylamide, activated carbon, filler" preferred Gongyi City Water Material Co., Ltd. Jinhua Yu Tai Branch (2), the company is located at: Jinhua City Mountain Ning Street West off street 1, 1st Floor, No. 279, over the years, Yu Tai purifier to provide customers the best quality service, contact: Wang Ruifang. Welcome to the new and old customers call, letter, visit the guide, business negotiations. Yu-tai Water expect to be your long-term partner!
