Titanium rod filter cleaning regeneration method:
Titanium rod filter in use after a period of time, will produce a certain degree of congestion, reduced flow, higher filtering front-end pressure, such as: higher under water pressure from 0.22 mPa to 0.3 mPa, show that titanium rod filter blocked at this moment, is to filter cleaning, titanium rod filter filter cleaning method generally has the following two cases:
1, for the new use of the filter element, the general use of water backwash, gas backblowing method to clean, that is, slightly greater than the working pressure (such as: 0.3mpa) water injection to clean. Recoil time is about 1~3 minutes.
2. For several times of backwashing, when the filtering effect is not obvious, it can be soaked in hydrochloric acid solution of less than 5% or sulfuric acid solution of less than 8% or NaoH solution of less than 10% at room temperature, and then cleaned with clean water. The specific choice of pickling or alkali washing should be based on the easy solubility of impurities in the filtrate in acid or alkali. If the impurities are soluble in alkali, the titanium rod filter element is soaked in alkali, and if the impurities are soluble in acid, the titanium rod filter element is soaked in acid.
