How To Filter Active Clay

- Sep 15, 2017 -

[Filter activated clay method] generally use clay filter or bag filter.

【Working principle】 The filter pump will be pumped into the tank through the inlet pipe and filled with the solid impurities in the filtrate under the action of the pressure, and the filter cake is formed on the filtrate. Filter through the filter into the liquid out of the tank, resulting in a clear filtrate. As the filtration time increases, the amount of solid impurities trapped on the filter is increasing, increasing the thickness of the filter cake, increasing the filtration resistance, increasing the pressure in the tank, and slagging when the pressure rises to a certain value , Stop feeding into the irrigation into the filtrate and the compressed air through the overflow pipe into the tank, the tank to be filtered into the other containers, and dry filter cake. Close the compressed air, open the butterfly valve, start the vibrator, so that the filter leaves vibration, the filter cake on the filter and the discharge of the bottom of the tank discharge.

【Activated clay】 is the use of clay (mainly bentonite) as raw material, the inorganic acid treatment, and then rinsed by water, dry made of adsorbent, the appearance of milky white powder, odorless, tasteless, strong adsorption, Substance, organic matter. Easy to absorb moisture in the air, placed too long will reduce the adsorption performance. When used to heat (to 80-100 degrees is appropriate) resurrection, but heated to 300 degrees Celsius above began to lose crystal water, the structure changes, affecting the fading effect. Activated clay is insoluble in water, organic solvents and various oils, almost soluble in hot caustic soda and hydrochloric acid, the relative density of 2.3 to 2.5, in the water and oil swelling is minimal.
