contaminants enter the soil. Nevertheless‚ heavy metals are the most toxic of all the pollutants. Among these‚ lead‚ cadmium‚ chromium‚ mercury and arsenic are most toxic and can cause multiple organ damages even when present in small amount. Although‚ these elements are necessary for soil animals as well as plants in extremely low quantities. However‚ anthropogenic activities like mining‚ smelting‚ fuel burning etc have disturbed the natural geochemical cycles of heavy metals which raises concern over their

Activated Sludge Process will encompass * Design of aeration basins. Relevant design parameters are * BOD load from the upstream process * Mixed Liquor Suspended Solids Concentration (MLSS – mg/l) – typically 2‚000 to 4‚000 * Sludge Age 5 to 25 days * Sludge settleabiltiy (SVI ml/g) typically 100-120 * Process Oxygen Demand (POD) * Generally fine bubble diffusers used in modern plant design – actual oxygen transfer efficiency dependent

DEFINITION OF COCONUT The coconut tree (Cocos nucifera)‚ is a member of the family Arecaceae (palm family). It is the only accepted species in the genus Cocos.[2] The term coconut can refer to the entire coconut palm‚ the seed‚ or the fruit‚ which‚ botanically‚ is a drupe‚ not a nut. The spelling cocoanut is an archaic form of the word.[3] The term is derived from 16th-century Portuguese and Spanish coco‚ meaning "head" or "skull"‚[4] from the three indentations on the coconut shell that resemble

Activated Sludge Process The activated sludge process is a wastewater treatment method in which the carbonaceous organic matter of wastewater provides an energy source for the production of new cells for a mixed population of microorganisms in an aquatic aerobic environment. The microbes convert carbon into cell tissue and oxidized end products that include carbon dioxide and water. Activated sludge plant involves wastewater aeration in the presence of a microbial suspension‚ solid-liquid separation

operates with subcontracting and sister companies in the coconut producing areas all around the country. CocoTech buys products from outside the Bicol region occasionally‚ but preferably buying of products from the Bicol region for reasons of quality control‚ logistics and efficiency. Through the company’s marketing partnership with CocoTech‚ demand for the products has increased tremendously.
