Side Stream Sand Filters for Industrial Cooling Tower

Product Description

 

Product Description

Working Principle
The shallow medium filter uses natural sea sand as the filter medium. Under a certain pressure, the water with high turbidity is filtered through a certain thickness of granular or non-granular natural sea sand, effectively intercepting and removing suspended solids, Organic matter, colloidal particles, microorganisms, chlorine, smell and some heavy metal ions, etc., and finally achieve a high-efficiency filtration device that reduces water turbidity and purifies water quality.

Product Features
1) The filter has two observation and inspection ports, the top is used for observation and feeding, and the bottom is used for emptying and maintenance. Each port adopts a completely leak-proof design. The system adopts the principle of hydraulic sealing, which is safe and reliable.
2) The unique 55 mushroom-shaped differential pressure compensation filter water collectors are the water pressure level of each part of the system in the filtering state. Balanced, high filtration flow rate and high efficiency, in the state of backwashing, an internal circulation is formed, and the backwashing efficiency is high and does not run off sand.
3) The water distributor makes the unfiltered water flow evenly through the packing layer even in the case of high flow, Maintain a flat water surface on the material layer.
4) The filter shell is made of stainless steel, steel lined with rubber or all plastic, with high efficiency and high pressure-to-weight ratio and corrosion resistance. The integral spherical shell can withstand the pressure of 0.59Mpa.
5) The inner layer of the filter is made of black polyethylene, which can resist environmental pressure, prevent embrittlement and not be affected by chemical substances Invasion.
6) For the pressure-compensated water collector, the opening near the middle is small, and the opening near the tail is large, so that the pressure from each water collector to the outlet is consistent. 7) Power saving: The system has a unique automatic backwash valve, the backwash of the sand filter tank is not carried out at the same time, but Under the normal operation of the system, backwashing is performed one by one, and there is no need to consider setting up a backwashing pump. At the same time, compared with other sand filtration equipment, the required lift of the filtration pump is 6-7m lower. 8) Water saving: due to its unique water replenisher and water collector, the system has unified specifications of the tank, so that the Compressed air is required to allow for a very uniform expansion of the media layer for effective backwashing. The water used for backwashing is filtered clean water, so the consumption of backwashing water is small. The backwash water flow of a single tank is only 1m3/min, and the backwash time is 60S. 9) Save maintenance costs: the whole system has no mechanical or electric valves, and only relies on unique multi-function valves to control the system backwash. Due to the unique multi-function valve has no wear and long life, no damage records within 10 years, and low management costs.

Product Structure
The fully automatic shallow sand filter has a spherical shell and a unique internal structure design to ensure smooth water flow during filtration and good filtration effect. Backwashing is the formation of numerous internal circulations, and the backwashing effect is high. Compared with the traditional sand filter, it has the advantages of automatic filtration, automatic backwashing, less sand and less water consumption.
