Agricultural Irrigation Automatic Backwash Bypass Sand Water Filter

Product Introduction
By-pass filter for chilled water as a by-pass filtering equipment of closed industrial circulating water is used to filter the circulating chilled water and its control modes consist of manual backwash and automatic backwash. The system is generally backwashed once every three to seven days in the circulating process, effectively improving the quality of chilled water and ensuring excellent and stable water quality after intervention to long-term running. The device has small water consumption and is widely used in the cleaning of all types of industrial and commercial chilled water circulation system as well as refrigerant water and heat medium water systems of central air conditioning, improving the stability of equipment operation. Users may weld and conned in parallel the by-pass filters in main return pipes depending on the conditions of circulation system and the pipe diameter should be determined based on the retaining water yield of parallel circulating water. The sewage water is then discharged into the sewerage network.


The characteristics of the filtration system
1. Manual or automatic control is available;
2. Water distributor is simple, uniform and reliable;
3. Finished water collector has high strength and long service life;
4. Easy to install. Only connect the inlet and outlet to the waste pipe when installing;
5. Less water consumption in backwash: a homogeneous filter is used, so that backwash cycle is extended and the total backwash water volume is greatly reduced;
6. High backwash efficiency: an advanced water collector is used, ensuring efficient backwash effect.
