SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in

Sewage treatment plan Sewage treatment is the process of removing contaminants from waste water and household sewage‚ both run off (effluents)‚ domestic‚ commercial and institutional. It includes physical‚ chemical‚ and biological processes to remove physical‚ chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Origins

and valuable resource. While industrial growth and unplanned water utilization for agricultural use have depleted ground water levels in many parts of India‚ the growth of urban clusters have brought pressure on available water. Increasing levels in sewage and industrial effluents have created the threat of pollution. Against this context of growing concerns about water‚ its recycling becomes important‚ for beneficial purposes such as agricultural and landscape irrigation‚ industrial processes‚ reuse

Marc Treadwell Environmental Science Final Paper Biomimicry The environment is suffering. Population is rising. Our natural resources are being depleted. Global warming is no longer fiction; it is fact. With these environmental catastrophes in mind‚ it is obvious that something must be done in order to preserve life‚ as we know it. Biomimicry is a field that concentrates on working with the environment to make human practices more sustainable. Biomimicry examines nature’s models

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal. Chemical contamination

Origins of sewage Sewage is created by residential‚ institutional‚ and commercial and industrial establishments and includes household waste liquid from toilets‚ baths‚ showers‚ kitchens‚ sinks and so forth that is disposed of via sewers. In many areas‚ sewage also includes liquid waste from industry and commerce.
