First, the scope:? Applicable to all types of swimming pools, water parks, seawater swimming pool, a large aquarium, large aquarium circulation purification, landscape water, rain water reuse treatment, advanced treatment and drinking water treatment sewage treatment. Second, the technical characteristics: ????? 1 Automatic suction DO: simulate the natural way water falls, increasing the contact area of ??water and air, mixes well with air aeration dissolved oxygen, so water rich in dissolved oxygen; the use of oxygen and pollutants sufficient oxidation reaction, thereby removing harmful substances in the water, while ammonia water, carbon dioxide and other harmful gases escape from the water surface. Meanwhile through the water mixture, can enhance the flocculation effect of pollutants in the water, which is conducive to the next step of the filter medium effective interception. . ????? Flotation to bubble: the role of dissolved oxygen by aeration, the water body produces a lot of foam, when the raw water to the filter layer, the foam floating on the water, not only through the filter layer below the floating on the surface. When the foam piled up for a long time can pass "outgoing pipes" exhaust or when the filter backwash tank, foam was washed away with the water, so the water foaming various organic substances can get more thorough removal. ?????? 3 multi-media fine filter: automatic or mechanical inflow of dissolved oxygen aeration after raw water through a fine filter flow distribution device (usually a set of four) was filtered through a multi-layer (typically 5 ~ 9-layer) Natural comply filter will "call" no, "floating" not fine solid particles trapped in the filter layer surface by seepage wells principle. Dispersion particle filter layer and the raw water is consistent particle size, which can reach more than 95% removal of contaminants, turbidity <0.3NTU. ?????? 4 second aeration DO: Through multi-layer filter media filter after water, flowing into the polyethylene tank after collection, in a tank of water through aeration device again dissolved oxygen aeration, and After the processing of water-activated, fresh technology. ?????? 5 automatic backwash: raw water passes through the filter layer, an impurity is *, the filter layer resistance increases, causing the water level to rise; when the water level rises to a certain height, the clever use of fluid mechanics automatic backwash. ; spend the night after washing the filter self-aligned reset, automatic reply filtered. And after backwash water by flocculation and sedimentation, and back into the filter for processing and reuse. Third, the product features: ???? (1) 80% of energy-saving, water-saving 90%, 90% of the drug section, save energy 90%. ???? (2) Full UPVC or stainless steel (304) Materials, non-corrosive, not-for-lining, do not change the filter, the device life of up to 40 years. (3) Hydraulic fully automated equipment, no valves, no maintenance, saving manpower of 100%. (4) Automatic aeration technology to effectively remove water urea, dissolving enzymes organic pollution. (5) The unique multi-layer ultra-fine filter media, the water turbidity <0.3NTU, quality is better than drinking water standards. (6) The filter layer containing sewage capacity, automatically adjusted backwash cycle, automating backwash, backwash time of only 3.5 minutes, full water conservation. Compact (7) device structure, small footprint, saving 50% of civil works. (8) without adding coagulant, coagulant, algaecide, a water never change, never sky blue and transparent. (9) Aircraft abundant: from 1A ~ 15A total of 15 kinds of models to choose from, stand-alone treatment capacity of 18m3 / h ~ 1600m3 / h. (10) out of a simple sand tank, using a multi-layer composite filter, the filter never harden, without replacement. Fourth, the technical parameters:
