Frequently Asked Questions
Q1 What is a backwash filter?
A backwash filter is a type of precision security and micro filtration equipment. It primarily serves as a filter core device with a filtration accuracy range of 0.1-500 m to protect downstream membrane elements.
Q2 Which equipment requires a backwash filter for protection?
It is typically configured at the ultrafiltration (UF) backwash pump outlet, nanofiltration (NF) devices, and reverse osmosis (RO) device wash pump outlets. This prevents particles from entering and scratching the membrane surface.
Q3 What materials are used for the vessel and filter element?
The pressure vessel can be constructed from corrosion-resistant glass reinforced plastic or a stainless steel shell. The filter element is composed of a skeleton and cotton filter cloth, mainly using polypropylene folding or melt-blown type elements.
Q4 What is the operating flow rate and filtration precision of the equipment?
The operating flow rate does not exceed 10m3/m2.h (measured by the surface area of the filter element). The filter precision is available in various specifications, including 0.22 m, 0.4 m, 1 m, 5 m, 10 m, 20 m, 50 m, 75 m, 100 m, and others.
Q5 What are the standard operating conditions and service life?
The design pressure is less than 0.4Mpa, the water pressure test pressure is 0.8Mpa, and the design temperature is 0℃-50℃. Under normal working conditions, the filter element maintains a service life of about 4-8 months.
Q6 Where is this backwash filter best applied?
It is ideal for the further purification of water that has low suspended impurities, specifically when the turbidity is less than 2-5 degrees.
