titanium rod filter cleaning?

the last small butterfly to introduce the stainless steel sintering network filter cleaning method when you mentioned the titanium rod filter, it is also can use repeatedly washing, small butterfly today about the detailed introduction to the cleaning method of the titanium rod filter, help customers to better use of it!

titanium rod filter after work run to a certain period, may be due to the filter element block, causing pressure flow is reduced, need recoil or backwashing regeneration. Regeneration cycle depends on the pressure and flow. Titanium rod filter in use after a period of time, will produce a certain degree of congestion, reduced flow, filter front increased pressure, such as from 0. 22 mpa under elevated to zero. More than 3 mpa, would then to filter cleaning, cleaning method generally have the following

alkaline cleaning with 3 - 5% of the 30 - pure sodium hydroxide analysis solution 60 minutes, the temperature about 40 degrees. The best in the ultrasonic cleaning machine. After soaking with filtered deionized water or water for injection, both inside and outside to neutral, electrical conductivity measurement. With the pure air & ge; 0. 4 mpa pressure blow dry.

acid soaking with 5% nitric acid solution more than 8 hours, the temperature of 40 degrees. The best in the ultrasonic cleaning machine. After soaking with filtered deionized water or water for injection, both inside and outside to neutral, electrical conductivity measurement. With the pure air & ge; 0. 4 mpa pressure blow dry.

for the new use of titanium rod filter, generally USES the clear water recoil, gas blowing method for cleaning, which is slightly greater than the working pressure, Such as: 0. 3MPa） Wash the water injection in the opposite direction. Time is about 1 to recoil 3 minutes. For anti - after washing, filtering effect is not obvious rebound, available * of less than 5% of the salt solution, or * * solution under 8%, or less than 10% NaOH solution soaking at room temperature, then use clean water.

the above acid and alkaline cleaning method can be used alone, also can be used interchangeably to cooperate with each other. If there are any conditions, can be combined with ultrasonic cleaning machine works best.

note titanium rod filter must often online reverse wash, clean with the above method can reduce the number of times, increase the service life of titanium rod filter.

above is titanium rod filter cleaning method of simple introduction, if you want to know more information, welcome to contact us! Url WWW.
