A Study of Laterite Particles in Adsorption of Oil and Grease

Abstract

A Study Of Laterite Particles In Adsorption Of Oil And Grease Grey water is the less polluted water from household uses containing oil and grease, food particles, soaps, laundry detergents, etc. It mainly contains phosphates, nitrates, ammonia and sometimes very few metal ions. Adsorption of oil and grease by suitable adsorbents can take an inexpensive approach.

This study shows the comparative performance of local adsorbent in water oil and grease adsorption. After some preliminary comparisons of oil and grease adsorption between saw dust, mulch as in bark chips, laterite, and charcoal. Laterite and charcoal are readily available, abundant, and inexpensive. Furthermore, this process can be incorporated into the process of gray water purification due to the simplicity of this removal approach. This had the added advantage of having a higher adsorption surface area.

Oil and grease removal is one of the main steps in wastewater treatment. Some equipment also discharges oils. Oil and grease subsequently enter the waste water. Oil and grease and hydrophobic and clinging to pipeline surfaces.

The presence of grease in wastewater is the main cause of sewer line clogging; restricting water flow and, most importantly, acting as a barrier to the transport of oxygen in aquatic media. Due to an oxidative attack on hydrocarbon, the transfer of atmospheric oxygen to pond water is masked. Sometimes graase layers plug the downstream flow. Removal of oil and grease is important as they have lower degradation rate, higher BOD and water-insoluble are.

Conclusion

Comparing the two adsorbents, laterite seems to be a promising star in the oil and grease removal process. Laterite and Coal are available locally in most parts of the world and can be purchased at very low cost.

It is quite evident that Laterite is a powerful adsorbing medium based on the results obtained in the different stages of this experiment. The contact period with adsorbent increased and thus increased efficiency for closer baffle spacing and slower flow rates. In addition, as the channel length also increased efficiency.
