Backwash refers to the transmission side-blown gas or liquid from film, the method that film surface pollution thing is removed.By backwashing film
Component, applies the pressure effect opposite with filtering direction, so as to force the pollutant in film surface and fenestra to depart from film silk, reaches
Clean film silk, mitigate fouling membrane, extend the effect of membrane module service life.It is many using periodically straight at present at family expenses film field
Discarded filter core is connect, the method for more renewing filter core maintains Water purifier filter performance so that family expenses membrane filtration core assembly turns into consumptive material, causes
The waste and loss of a large amount of material resources and financial resources.Therefore, extend water purification life of product using backwashing technology, reduce and even prevent filter
Core substitutes, and realizes energy-conserving and environment-protective, is the inevitable choice of family expenses film water purifier industry.
