Product overview: The shallow sand filter is spherical and has a unique internal design to ensure a smooth flow and good filtering effect. In backflush, numerous internal circulation is formed, and the recoil efficiency is high. Compared with the traditional sand filter, it has the advantages of automatic filtration, automatic backwash, less sand and less water. Structural features: 1. The filter is provided with two observation and inspection ports, the top one for observation and feeding, and the bottom one for emptying and maintenance. Each port is designed to prevent leakage. 2. Unique 55 mushroom-shaped pressure differential compensation filter water collector to balance the water pressure of each part of the system under the filtration state; High filtration velocity and efficiency; In the backwash state, internal circulation is formed, and the recoil efficiency is high and the sand is not running. 3. The water distributor enables unfiltered water to flow evenly through the packing layer, even at high flow rates, and maintains a level water surface on the packing layer. 4. The filter housing is made of stainless steel, steel lining glue or all-plastic, with effective high pressure weight ratio and corrosion resistance. The integrated spherical shell can withstand the pressure of 0.59mpa. 5. The inner layer of the filter is made of black polyethylene, which can resist the pressure of the environment and prevent it from cracking and from being attacked by chemicals. 6. The pressure compensation water collector has a small opening close to the middle and a large opening close to the tail, so that the pressure from each water collector to the outlet is consistent. Technical parameters: Diameter of inlet/outlet main pipe DN(mm):200 Diameter of drain pipe DN(mm):100 Flow (m3/h) :80 Maximum working pressure (MPa) :0.6(1.0) Filter area (m2) : 2.26 Total length (mm) :2640 Sewage valve interface :4 "x 3" Designed inlet pressure: 0.2-0.4mpa Backwash flow :35-55m3/h Working pressure: less than or equal to 0.6mpa Backwash consumption :< 1% of filtered water Incoming water quality :SS=15-30mg Backwash method: endogenous backwash (except mononuclear) Effluent quality :SS is less than 5mg Control mode: dual control of time and pressure difference Pressure loss: no more than 0.1Mpa
