Abstract- This project is an attempt to investigate organic waste pollution that may pollute fresh water and influence aquatic environment. Dairy wastewater contain large amount of organic wastes, so the removal of this wastes are very essential but for that common techniques not enough. Enzyme and adsorption units are used to assess the water quality and humiliation prospective of organic waste from wastewater. The wastewater formed in dairy comes mainly from the cleaning of company’s means of transport and of production, more than 90% of the organic content consist of milk and production residues. High concentration of this fat and oil in wastewater affects biological wastewater treatment process by forming a layer on the water surface, which decreased the oxygen transfer rate in to the aerobic process. Enzymes like protease, lipase, amylase, and cellulose should play essential roles in biological wastewater treatment process. Several components and environmental variables that were dissolved oxygen, and adsorption material amount studied to assess the removal performance of organic load. The study stressed out natural material (zeolite) that enhanced organic reduction under optimum conditions.

Keywords- zeolite column, biological enzymes, BOD, COD, pH, turbidity, conductivity, TSS, TDS, LSC and LEU.

I. INTRODUCTION

Organic toxic waste (oil, fat and grease) causes ecology damages for aquatic organisms, plant, animal, and equally, mutagenic and carcinogenic for human being. They discharge from different sources to form a layer on water surface that decreases dissolved oxygen. And this layer reduces biological activity of treatment process where oil film formation around microbes in suspended matter and water. This lead to decrease dissolved oxygen levels in the water. Then oxygen molecules are difficulty to be oxidative for microbial on hydrocarbon molecules and cause ecology damages to water bodies.The effects of oil and grease in wastewater steam to include physical blockages in sewers, pump, screens and filter distributor arms, and these consequently lead to increase maintenance costs. These effects also include accumulation of lighter oils in the wet wells of pumping stations, fouling of electrodes or float systems which leads to pump controls failures. Where the nature of oil is highly flammable, it leads to explosion hazard in the treatment works. Excessive grease in the wastewater stream causes difficulties in sludge pressing because of ‘blinding effect’ on the filter cloths. Oil and grease interfere with aerobic biological wastewater treatment processes by reducing oxygen transfer rates.
