Activated carbon titanium rod filter has the characteristics of high pressure, strong acid, strong alkali, corrosion resistance, and the filter element can be repeatedly regenerated and used. It is a hollow filter tube made by processing titanium metal powder through powder metallurgy method without high-temperature sintering. It is widely used in liquid-solid separation in industries such as food, beverage, medicine, and chemical, and is particularly suitable for decarbonization filtration in large infusion and injection production lines in the pharmaceutical industry. This series of products has a compact structure, beautiful appearance, and is produced according to GMP standards. The pipe fittings are connected using standard quick release connections, which are easy to disassemble and clean.

After a period of use, the titanium rod filter cartridge will experience a certain degree of blockage, resulting in a decrease in flow rate and an increase in pressure at the front end of the filter, such as from below 0.22mPa to above 0.3mPa. At this point, the filter cartridge needs to be cleaned using the following methods:

For newly used filter cartridges, the method of backwashing with clean water and blowing back with gas is generally used for cleaning, that is, using water slightly higher than the working pressure (such as 0.3mPa) to inject water in the opposite direction for cleaning. The recoil time is about 1-3 minutes.

When the filtration effect does not significantly improve after multiple backwashs, a hydrochloric acid solution of less than 5%, sulfuric acid solution of less than 8%, or NaOH solution of less than 10% can be used to soak at room temperature and then rinse with clean water.

The specific choice of acid washing or alkali washing should be based on whether impurities in the filtrate are easily soluble in acid or alkali.
