1. For decarbonization and filtration in the pharmaceutical and chemical fields, backflushing and backwashing methods combined with ultrasonic cleaning are often used to achieve the best results.
2. In the water production industry, because most of the water-insoluble salts and oxides retained on the surface of the filter element are soaked in 5% nitric acid, the cleaning effect can be achieved without ultrasonic cleaning.
3. Filtration of raw liquid should be combined with the chemical properties of pollutants, and the following methods should be used for cleaning:
(1) Alkaline washing: soak in 3-5% sodium hydroxide analytically pure solution for 30-60 minutes at a temperature of about 40 degrees, which is the best in ultrasonic cleaning machines. After soaking, rinse the inside and outside with filtered deionized water or water for injection to neutrality, and measure the conductivity. Dry with pure air ≥0.4MPa pressure.
(2) Pickling: soak in 5% nitric acid solution for more than 8 hours, and the temperature is about 40 degrees. Best in ultrasonic cleaners. After soaking, rinse the inside and outside with filtered deionized water or water for injection to neutrality and lateral conductivity. Dry with pure air ≥0.4MPa pressure.
(3) Organic pollution can be combined with surfactant cleaning, and the cell debris pollution system combined with enzyme cleaning is more effective (food and beverages can be cleaned with high-concentration citric acid).
(4) The above methods can be used alone or alternately with each other. If conditions permit, it is best to combine with an ultrasonic cleaner.

What is Titanium aeration head?
The microporous pure titanium aeration head is made of industrial pure titanium powder (purity ≥99.6899%) as the main raw material, which is sintered at high temperature and high vacuum.
The spherical bottom diameter of spherical titanium aeration head is Φ100mm, the arc surface is Φ125mm, the wall thickness is 3mm, the aeration bubbles are 0.1-2mm, and the aeration resistance is small, the gas-liquid interface area is large, the bubbles diffuse evenly, and there will be no hole blocking. The energy consumption of conventional aeration is reduced by 40%, and the amount of sewage treatment is nearly doubled.
Titanium aeration headhas the advantages of strong corrosion resistance, high acid and alkali resistance, and long service life. This product is suitable for urban sewage, new expansion of large water plants and renovation of old aeration tanks, as well as ozone aeration in water treatment industry, catalytic gas aeration in chemical industry.
etc.
If you have any question about production just let me know it.
