Outdoor swimming pool water filters

As people's living standards improve environmental awareness and green landscape pond has become a living cell or a public place in a beautiful natural scenery. It can not only beautify the environment, decorative garden, bring artistic effect and atmosphere, and clean air is more humid, so the deterioration of the urban environment has been the role of clever improvements. But now many fine view of the water the designer in the design process due to lack of water on the landscape pond water purification considerations, resulting in the future because many landscape pool water deterioration had a little bad influence. And Hainan Rudder for landscape water, there is due enriched N, P and other nutrients algae blooms easy to grow and produce potentially harmful water quality deterioration occurs landscape water body eutrophication. Not as stable landscape water quality treatment, could easily lead to deterioration of water clarity, and because of the propagation of algae can also cause depletion of dissolved oxygen in water, making the water of oxygen and the breeding of anaerobic microorganisms cause water black smelly. In order to prevent and control the landscape water quality deterioration, it requires scientific and reasonable to the original ecosystem bioremediation, purified water contamination by biological treatment measures to improve water quality, water quantity control bacteria and algae, and use of biological self-purification of water bodies, form a benign cycle of ecological balance system to solve the problem fundamentally deterioration of water quality. Henan Water Treatment Equipment Co., Ltd. developed (gravity-free valve filter), is the feedback based on years of successful operating experience and the views of users, combined with a variety of water characteristics and fluid control theory, constantly updated sound, successfully developed a new and efficient exposure energy saving air circulating water treatment equipment. The device uses a non-toxic PVC material as the package of equipment UPVC materials, corrosion resistance, aging, long life, the age of more than 30 years. Since then abandoned the cumbersome and easily corroded metal and short-lived variety of glass fiber reinforced plastic material. JR series of gravity water system in the country and a leading international position, making sophisticated technology, all handmade, hydraulic fluid control more intelligent automation and rationalization. Equipment selection can be based on user needs, choose the same type of water treatment equipment. Transformation before gravity-free valve filter the gravity-free valve filter with no large valves, positive head was filtered, washed automation, low cost and ease of operation management, etc., which have been in rail or water in small and medium towns wide range of applications. But there are gravity-free valve filter following question: complex water systems, construction demanding; water process gas is easy to clip, affecting the normal filtration and backwash; a single-layer quartz sand filter, filter water production is low, can not water supply to meet the increasing demands. Shangrao Railway East Gate water by the water supply expansion project is original size 12 000m3 / d expansion to 20 000m3 / d, which adds 320m3 / h of gravity-free valve filter 1. On the national standard figure 240m3 / h of gravity-free valve filter for the technological transformation after transformation, gravity-free valve filter water production increased to 320m3 / h, compared with more than successfully solved several aspects. Figure valveless construction works construction and transformation after transformation after 1. Filtration work: the muddy water flowing into the water after a water mains distribution box 22, the water distribution weir 2 into drains into the shaft 3, after the energy dissipation of energy dissipation plate 4, evenly distributed over the filter layer 5 By supporting layer 6, a small resistance to water distribution system 7 into the bottom of the water distribution space 8. Filtered water from the bottom of the water distribution space through the communication area 9 rose to flush tank 10. When the tank water level reaches the top of the weir 11 drains overflow into the canal, and finally into the clear pool. Gravity-free valve filter (a) non-valve filter main features: non-valve filter is a no valve, run entirely by the hydraulic automatic control filter. It is divided into two kinds of gravity and pressure, gravity and more generally supporting the use of the clarifier, pressure does not exceed 150 degrees for the use of raw water turbidity for small, decentralized nature of the water supply project, but the same principle work principle of its work is the same, but the shape of the planar circular or square lines; (ii) non-valve filter constructed: valveless mainly consists of five parts, namely the top of the flush tank, the middle filter chamber, the bottom of the catchment chamber and the intake unit and flushing siphon devices. (C) valveless working process: running, runoff from the inlet into the filter, through the filter layer filtration, water flows into the upper portion of the connecting pipe from flush tank, after the tank is filled from the outlet pipe flows into the clean water tank . With the filter operation, the filter layer after interception resistance gradually increases, the water level rises siphon tube rising, when the water level reaches the siphon auxiliary nozzle tubes, sharp drops of water from the tube by suction will continue next the tube air away, generating a negative pressure in the siphon, so that siphon tube riser and falling water levels are rising quickly, the confluence of communication formed a siphon, forming automatic backwash. Thus, when the flush tank water level gradually decreased, down to the moment when the siphon tube mouth less air into the siphon, siphon action will be destroyed, that is the end of the washing process, then filter and reuse water, began circulating operation of a new cycle . (IV), use 1, next to the filter used in petrochemical, textile, electronic machinery and other industrial enterprises circulating cooling water treatment. 2, used in factories, cities, towns water plant filtration process. 3, used in swimming pools, fountains, water treatment water features. 4, it can also be used to filter and softening treatment of industrial waste water treatment applications. (V), the scope 1, for the water filtration treatment plant, the water suspension should be less than 15mg / L, effluent suspended solids less than 3mg / L. 2, for circulating cooling water side stream processing, water suspensions 15-30mg / L, effluent suspended solids is generally less than 5mg / L. 3, for the "dosing coagulation process", the influent suspended solids 50-100mg / L, effluent suspended solids is generally less than 5mg / L. (VI), the main design data 1, design filtration rate: 10m / h 2, the average backwash intensity: 15L / S.m2 3, backwash lasted: 3-5min 4, of the final head loss: 1.7m Henan Hairun Germany focused treatment!
