CoatCel® Alpha cellulose is the purest form of cellulose, free from lignin and hemicelluloses. It is produced from purified wood pulp having 99.5% purity, producing almost ash less. Alpha cellulose is an inert porous material used to separate solid (impurities and turbidity) from the liquid, making almost free from suspended solids.


Application of CoatCel ® Alpha Cellulose

Brine Filtration

Sigachi designs, manufactures, supplies, erects and commissions brine filtration plant complete with test run responsibility for absolute critical solid separation up to 0.3 micron size less than 0.5 ppm before ion exchange process in Caustic-Chlorine (chlorine alkali) membrane cell based plant. This combines pre-coat tank, body feed tank, filtration units, pumps, valves, atomization (based on PLC or DCS) and many other devices and units. The filtration unit's purpose is to remove suspended solid in the brine and deliver clear brine to the next resin exchange tower. Clarifier, Sand Filter (Anthracite), Brine Filter, Ion Exchange Resin and Cells are in the order of the general process of brine treatment. The brine filter always reduces the size of suspended solid (SS) from 0.3 μm and above to less than 0.5 ppm. This is the key unit for protecting against damage by Ion Exchange Resin and Ion Membrane Cells.

Extensively used in Caustic Soda industry for Filtration levels of PPB (Parts Per Billion).

Typical equipment where Cellulose used as Filter Aid are

Advantages of using Cellulose in Brine Filtration

Beverage & Edible Oil Filtration

Wine Filtration

he Technical and Commercial Advantages of using Cellulose as Filter Aid in Wine Industry are:

Low Weight Reduced Consumption
Low consumption Less Losses and Waste
Soft Fibres Less wear & Tear in Plant and Machinery
No crystalline Component Not Carcinogenic
Derived from Plants Disposal is not an issue

Mining & Metal Filtration

In addition to the basic advantages of Cellulose as Filter Aid, it has an upper hand on account of the following
