    • This project, aimed at investigating the anaerobic processes in septic tank as a waste water treatment option using waste water from septic tank and Soakaway as sample A and B respectively. It was observed that after the  analysis, sample A (septic tank which has fresh waste water) has higher value in conductivity =1708us/ cm3, Total slid = 17490mg/l, Dissolved solid (16420mg/l), COD = (106mg/l), DO = (0.6883mg/l) and BOD = (106.6883mg/l) compared to sample B (Soakaway which contains waste water that has under gone anaerobic treatment) with values in conductivity =1170us/cm3, total solid = 14870mg/l dissolved solid = 12310mg/l COD = 68mg/l BOD = 68.4917mg/l. This is presented table 4.1. This indicates that there are more contaminant is septic tank than in the soakoway which has under gone anaerobic waste water treatment. From this present study, it was observed that septic tank is a rehable waste water treatment plant.

    • CHAPTER ONE - [ Total Page(s): 2 ]Since all natural waterways contain bacteria and nutrients, almost any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above).Those biochemical reactions create what is measured in the laboratory as the biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the chemical oxygen demand (COD). Both the BOD ... Continue reading---
