Wastewaters from three different sources, private residence (domestic), medical clinic (institutional) and polymer industry (industrial) were characterised for their pollution potentials. The results of analysis show pH of 7.6, 6.5 and 6.3 for domestic, institutional and industrial wastewater, respectively. The DO, BOD and COD was found to be 4.01, 66 and 114 mg/l for the domestic wastewater, 3...

to study the feasibility of anaerobic filter in raw sewage and slaughter house wastewater treatment, slaughter house wastewater treatment, a batch flow pilot plant was designed. in phase one, with a detention time of 3-days and no mixing, the maximum reduction in cod was 23%. in the second phase, with a detention time of 2-days and complete mixing, glucose was added to the raw sewage, the reduc...

Hydrogen peroxide has been used for decades in developed countries as an oxidizing agent in the treatment of water, domestic sewage and industrial effluents. This study evaluated the influence of the concentration of H2O2 and pH on the inactivation of Escherichia coli cells and the disinfection of sewage treated. The results showed that the inactivation rate increased with pH and H2O2. The pres...

abstract population increase, limitation of water resources, and increasing volume of municipal wastewater, has caused the necessity of wastewater reuse. application of wastewater on soils seems to be the most economical method of its disposal and by percolating wastewater through the soil, its chemical quality is improved. for this purpose, a greenhouse experiment was carried out with polyethy...

Background: Constructed wetlands are systems designed based on the utilization of natural processes, including vegetation, soil, and their associated microbial assemblage to assist in treating different types of wastewater. Methods: Two local Appalachian plants (Louis latifolia and Phragmites australis) were planted into smallscale constructed wetlands to treat domestic wastewater in the North ...

Constructed wetlands (CW) are an alternative localized treatment technology suitable for reducing BOD, COD, NPK and pathogens to acceptable levels for subsequent use of treated water, especially for irrigation. Dissolved chemicals and heavy metals are also reduced to an extent. CWs are extensively used in developed countries for secondary and tertiary treatment of domestic sewage and treatment ...

The objectives of the project were to: • Protect coastal waters from pollution with domestic wastewater. • Protect the health of the local residents through improved housing with safe sanitation and wastewater treatment facilities. • Demonstrate constructed wetland technology. Bayawan was the first city in the Philippines that built a constructed wetland for domestic wastewater treatment. There...
