A. Function 1. Can adsorb organics, bacteria, colloidal particles, microorganism in the water 2. Can remove color and smell in the water 3. Can adsorb ammonia, oxygen, bromine, iodine etc. non-metallic. 4. Can adsorb metal ion, like Ag, As, Bi, Co, Cr, Hg, Sb, Sn B. Application Widely used for food, medicine, electron, chemical, industry sewage etc. C. Feature: 1. Active Carbon adsorbing filter takes hydraulic analogy design, and takes suitable size but high efficiency active carbon whose surface bigger than 1000m2/g, achieving both upper layer special filtering and lower layer good adsorbing function, increasing water purification degree and carbon life-time. 2. The rest Cl after HG active carbon adsorbing: ≤0.1PPM. 3. Excellent adsorbing bad smell, organics, colloid, iron and rest Cl 4. Excellent reducing turbidity, colored, pollution, and also good to following system(like reverse osmosis, ultra-filter, ion exchange etc.) D. Technical parameters 1. Water inlet turbidity: <15 degree 2. Water outlet turbidity: <3 degree Working parameter: 1. Filtering speed: 15-20m/h, water head loss: 1.7m 2. Capacity: 0.5m3/h~125m3/h 3. Back washing: 4-15L/s.m2 washing time: 5-7min 4. Back washing expansion rate: 40-50% 5. Filter media: active carbon 6. Cushion layer thick: 200-400mm, filtering layer thick 800mm 7. Working method: pressure type 8. Water flow from upside down, pressure: ≤0.6Mpa 9. Temperature:5 C~50 C
