ABSTRACT

Wide variety of microorganisms may occur in wastewater which cause many diseases for human and animals. Wastewater is one of the main factors that effect on the environmental population. Biochemical treatment of wastewater becomes one of the important resources for irrigation.

In determining the optimum solutions for the advanced treatment of wastewater for irrigation, the recent technology for water applies its comprehensive know-how of biochemical processes. In the present study the wastewater was mixed with Liquid life micro organism (LLMO), to minimize sludge processing costs as well as decreasing the level of BOD, TSS, TDS, Oil and Fats in the treated wastewater. The results indicated that LLMO product systems have been successfully used to decrease sludge production, reduces the mass of solids generated per pound of BOD removed. The quality of the treated wastewater was improved and became suitable for irrigation of non edible crops. On the other hand, reduced sludge blanket means more retention time, better effluent, and reduced potential odors.

Key words: Biological treatment, wastewater, Long life microorganism (LLMO), Mixed Liquor Suspended Solids (MLSS).
