Activited bleaching earth is powder clay,made from bentonite material, also called activited clay,activited fuller earth is a fine,light color powder with a highly porous inner structure and a numbers of acid sites on its surface.It mainly used for refining of vegetable oils and minerals oils, and hardened fats,and ects, and well suitable for remove of polar compounds like chlorophyll, carotinoids, phospholipids, peroxides ,impurities etc by chemisorption/physical adsorption and acid catalysis.

Bleaching Activity
A hard to bleach oil, with known ffa and color is treated with various dosages of Refoil Earth under standard vacuum, temperature, contact time and stirring. The colors are measured in Lovibond Tintometer and the results are compared with standard earth results.

Acidic property
Measurement of residual free acid content as well as pH value of water solution filtered out of the Bleaching Earth are routine test with titration method as well as pH meter and stringent standards are maintained for the same.

Water content
Moisture content is measured in a standard laboratory drying chamber as well as by Karl-Fisher- titrations.

Particle – size distribution
It is checked on standard sieves by careful air stream sieving as well as on particle size analyser.

Filtration property
We have a standard, exhaustive, test method for determining the filteration properties of our bleaching earth. We filter oil under standard conditions of temperature and pressure difference over an oil-wet-filter-cake. Stringent standards are followed and maintained to ensure fast filtration rate of Refoil Earth.

Oil Retention
This is a supplementary test carried out in conjunction with filtration test. It depends on activation and particle size of Bleaching Earth and is maintained at the minimum levels url:http://www.zhtworld.com
