Working: Bleaching clay;Bentonite,
acid-leached;Activated bleaching earth; Activated clay/Bleaching
clay; bentonite acid-leached powder can emerge and separate some
matters by effective, such as phosphorus oil,soap and trace metal
oil and aflatoxin,pigment,colloid,impurity,dram
heavy metal in lipid which can cause oxidant and activator
toxic.

pigments like carotenoids, chlorophyll,
Pheophytine •Removal of gums (phospholipids),

oils •Reducing and Controlling
different oil parameters like Peroxide value, Anisidine value,
UV-absorption value.FFA contents etc. •Purification of Aromatic
Compounds in case of mineral oils & waxes and removal of
Sulphuric acid, Tars acid, Sludge, Sulfonic acid
etc. •Other
Applications like Bleaching of Sulphur,In Effluent treatment
