Potential of using fermented organic wastes to remediate slaughterhouse wastewater

Abstract

A recent study emphasizes on the potential of using fermented organic wastes to remediate slaughterhouse wastewater has been conducted. Organic wastes have become serious issues towards the environmental pollution. The organic wastes will disposed to landfill and at the same time it will produce a liquid known as leachate that eventually will go into the ground and enter the ground water table. This serious issues need to be taken care of. Instead of disposed it to landfill, it can be converted into something useful which it can be a method of treating polluted water. A simple fermentation process is carry out in a ratio of 1:3:10 which are brown sugar, organic wastes and water respectively. The fermentation process is then store in a dark place with room temperature for 3 months. Samples of wastewater are taken from slaughterhouse at Jejawi will be used as the samples that will undergo treatment using the fermented organic wastes. After obtaining the fermented organic wastes solution, a percentage of 10%, 20% and 30% are used to mix with wastewater. In this test, the fermented organic wastes shows a percentage of removal for all parameters which are BOD, COD, TSS, turbidity, DO and pH. The most efficient on removal is 30% which obtain the highest removal percentage which are 46.34%, 8.97%, 37.5% and 37.49% for COD, BOD, TSS and turbidity respectively. However, the results for all mixing percentage do not show a uniform result. The result seems to be increase and decrease from week 1 until week 3.
