Ohio State University Extension Fact Sheet Food, Agricultural and Biological Engineering 590 Woody Hayes Dr., Columbus, Ohio 43210 Wastewater Treatment Principles and Regulations AEX-768-96 Karen Mancl Sewage is the wastewater released by residences, businesses and industries in a community. It is 99.94 percent water, with only 0.06 percent of the wastewater dissolved and suspended solid material. The cloudiness of sewage is caused by suspended particles which in untreated sewage ranges from 100 to 350 mg/l. A measure of the strength of the wastewater is biochemical oxygen demand, or BOD . The BOD measures the amount of oxygen microorganisms require in five days to break down sewage. Untreated sewage has a BOD ranging from 100 mg/l to 300 mg/l. Pathogens or disease-causing organisms are present in sewage. Coliform bacteria are used as an indicator of disease-causing organisms. Sewage also contains nutrients (such as ammonia and phosphorus), minerals, and metals. Ammonia can range from 12 to 50 mg/l and phosphorus can range from 6 to 20 mg/l in untreated sewage. Sewage treatment is a multi-stage process to renovate wastewater before it reenters a body of water, is applied to the land or is reused. The goal is to reduce or remove organic matter, solids, nutrients, disease-causing organisms and other pollutants from wastewater. Each receiving body of water has limits to the amount of pollutants it can receive without degradation. Therefore, each sewage treatment plant must hold a permit listing the allowable levels of BOD

English Search Home Countries Health topics ... Emerging Issues Water Sanitation and Health (WSH) About WSH Databases Guidelines Training ... Partnership Location: WHO WHO sites WSH Wastewater Use Wastewater use As freshwater becomes increasingly scarce due to population growth, urbanisation and, probably, climate change, the use of wastewater in agriculture, aquaculture, groundwater recharge and in other areas will increase. In some cases, wastewater is the only water resource available to poor, subsistence-level farming communities. Although there are benefits to using wastewater in agriculture - including health benefits such as better nutrition and food security for many households - uncontrolled use of wastewater frequently is associated with significant negative human health impacts. These health impacts can be minimized when good management practices are implemented. Guidelines for the safe use of wastewater in agriculture, need to find the right balance between maximizing public health benefits and still allowing for the beneficial use of scarce resources. Guidelines need to be adaptable to the local social, economic and environmental conditions and should be co-implemented with other health interventions such as hygiene promotion, provision of adequate drinking water and sanitation, and other primary health-care measures. WHO published Guidelines for the Safe Use of Wastewater and Excreta in Agriculture and Aquaculture in 1989. These guidelines have had a major impact on the rational reuse of wastewater and excreta in countries world-wide. The WHO guidelines for the safe use of wastewater and excreta in agriculture and aquaculture are currently under revision with expected publication in 2004.

Pollution Prevention Fact Sheet Sector: Printers/Lithographers Wastewater Environmental Concerns Is Wastewater a Hazardous Waste? Pollution Prevention Substitute ... Training and Planning Environmental Concerns Printing wastewater is generated from image processing, press washing and floor washing, and includes any other water or fluids that go down floor drains, sinks or other fixtures. It does not include 'sanitary' wastewater from kitchens or bathrooms. Printing shop wastewater typically contains chemicals such as spent developers, fixers, cleaners, and fountain solution. In some instances it may possibly contain oils, inks and solvents. The concern is that all of these chemicals have the potential to cause serious pollution if discharged through a dry well or septic system to the ground. Chemicals discharged in this manner will migrate and can render drinking water supplies unfit for human consumption. If discharged directly or indirectly to surface water, such as a stream, these chemicals can render the water toxic to fish and other aquatic life. Is Wastewater a Hazardous Waste?

Meet EMWD Your Water Service Wastewater Service Conservation Corner Water Education WWW Resources Doing Business Wastewater Treatment Treating wastewater is critical to public health. It is also an important way to help conserve and preserve our water supplies. Every gallon of water that can be reused means that one more gallon can remain underground; or one more gallon doesn't need to be imported from Northern California or from the Colorado River. With about 25,000 acre-feet of recycled water sold annually by EMWD, recycled water is a significant resource. In comparison, domestic and agricultural customers take about 75,000 acre-feet a year of fresh water. There are two grades of recycled water: tertiary water and secondary water. Secondary Water After having gone through a primary (mechanical) process using screens, settling tanks and skimmers, a higher (biological) treatment level incorporates bacteria which feed on nutrients. Primary treatment removes about 70% of suspended solids; secondary treatment removes 85-90% of the remaining suspended solids and other impurities.
