티타늄 로드 필터의 세척 및 재생 방법 

일정 기간 작동 후 티타늄 로드 필터 요소가 막혀 압력 강하가 증가하고 매체 흐름이 감소합니다. 이 경우 역세 또는 역세척을 통한 재생이 필요합니다. The frequency of regeneration is determined by the calculated values ​​of pressure and flow. During long-term operation, the filter gradually becomes clogged, which is manifested by a decrease in flow rate and an increase in pressure at the filtration inlet. For example, if the pressure increases from less than 0.22 MPa to more than 0.3 MPa, it is necessary to clean the filter. 다음과 같은 주요 청소 방법이 있습니다.

New titanium rod filters are usually cleaned by backwashing with clean water and backwashing with gas: flowing clean water in the reverse direction at a pressure slightly above operating pressure (eg 0.3 MPa). 역세 시간은 1~3분입니다. If, after repeated backwashes, filtration efficiency is not restored, the product is soaked at room temperature in a solution of hydrochloric acid with a concentration of less than 5%, sulfuric acid less than 8% or sodium hydroxide less than 10%, then thoroughly washed with clean water.

Acid and alkaline cleaning methods can be used either separately or alternately. With an ultrasonic cleaning unit, cleaning efficiency increases significantly.

Note: Regular regeneration of the filter without dismantling by backwashing and blowing allows you to reduce the frequency of chemical cleaning and increase the service life of the titanium filter element.
