and unusual sights happened recently‚ such as Yangtze River turns blood red in Chongqing. Water pollution in China are usually triggered as accidents. Uncontrollable wastewater discharges are usually caused by the inadequate wastewater storage and sewage treatment facilities. Industrial wastewater outflows‚ and such accidents lead to reduction of fresh drinking water supply as the fresh water is used to dilute the pollutant released immediately. The causes of degradation of fresh drinking water level

usually come from human sewage. As pathogen numbers increase‚ so does the risk of human health. Biochemical Oxygen Demand: Organic wastes that decay in a body of water. decrease the amount of oxygen found in it. The living things in the lake need oxygen to survive. If the oxygen level is depressed to zero‚ all fish in the lake die. Any decomposition that does not contain oxygen starts to generate noxious gases such as Hydrogen Sulfide. Pulp and paper mills‚ and municipal sewage causes BOD. Nutrients:

save money. Industrial and community sanitation along with control and treatment of human waste and industrial waste are necessary to reduce water pollution. More than 95% of urban sewage is released into the near water way or field due to inadequate or lack of treatment plants in developing countries. More sewage water treatment plants should be installed in cities and industrial belts’

EFFLUENT 9 GLOSSARY 10 DEFINITIONS OF TERMINOLOGY 10 THE BIO-MITE® WASTE WATER TREATMENT SYSTEM 1. INTRODUCTION This document provides an overview of the sewage treatment process registered under the trade name Bio-Mite® (Biomite). The Biomite water treatment system is designed to biologically treat raw sewage through a bacterial breakdown process requiring no chemicals. The waste stream flows through the plant under gravity‚ ensuring quiet operation and low energy demand.

based on available data show that half the organic waste is from the domestic sector (PEM‚ 2003). As stated in the EMB report‚ domestic wastewater discharges contribute highest to the BOD load as the lack of sewage treatment system allows more than 90 percent of inadequately treated domestic sewage to be discharged into surface waters‚ which contain bacteria and viruses that threaten human life. Geographically‚ data show that one-third (30 percent) of BOD generation comes from Metro Manila and Region
