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 E. Installation 1. Firstly install collection system, and open roof cover or open upper flange cover. 2. Take off distribution system 3. Put in clear big gravel, small gravel inside of filter (support layer) 4. Put in clear active carbon(filtering media) 5. Install upper cover(or upper flange cover) and seal, tighten. 6. Connect operation system, and other relative fastenings.
