Bleaching Clay Filtration Percolation
Bleaching clay is then mixed with the pre-bleached oil, bleached and filtered in a clean filter. DoublePass bleaching is the most efficient process for reducing bleaching clay consumption and oil losses. Packed bed bleaching is a less common process that pushes the oil through a series of filters pre-coated with a bed of fresh bleaching clay.

CHAPTER 6 BLEACHING CLAY
The commercial product is prepared in granular form for use in the percolation process on petro- leum oils. For the most part, bleaching clay is used commercially in the de- colorization of animal, vegetable and petroleum oils, fats and waxes. It is applied in two ways: (1) by the percolation method and (2) by the contacting method.

Optimization of Bleaching Process
Silicate/clay bleaching dual filtration bleaching [1]. Figure 7. Countercurrent bleaching system [7]. Figure 8. Double-pass bleaching system [8]. Improved Oil Quality. Bleaching is the physical and chemical interaction of an oil or fat with bleaching earth to improve its quality. One definition of quality is “to reach a level of excellence.” However, with respect to oil specifications
Characterization, Acid Activation, and Bleaching
3.4. Bleaching Evaluation. The bleaching assessment for the natural clay as evident from Table 3 is indeed very poor with a colour reduction of 9.091%. Upon activation with increasing HCl concentrations, there was increase in the Lovibond colour reduction from 9.091% to 27.275% as the concentration of the HCl used for activation varied from 0.2 M to 3.0 M as aptly displayed in Figure 3.

THE BLEACHING CLAYS USGS
Active bleaching clays result when bases iri the surfaces of the clay particles are replaced by the hydrog·en:_ and hydroxyl of acid. These are driven off as water by heat, leaving the open bonds essential for bleach ing. Bleaching power is at a maxirrn:un when only part of the bases are removed. If the leaching of bases is carried too far, the material de generates into an ordlnary clay

What Is the Infiltration Rate of Clay Soil?
Clay soils can be expected to have an infiltration rate of 1 to 5 millimetres per hour or about 0 to 0.5 inches per hour. Compared to the infiltration rate of a loam soil (10 to 20 millimetres per hour 0.4 to 0.8 inches per hour) this is very slow. With an infiltration rate this low it is very difficult to grow most agricultural plants and grasses. This is because the infiltration rate is slow
