Wastewater management focused, for many years, on the treatment of wastewater to protect the environment and safeguard the public health. An integrated approach to wastewater management is more extensive and includes the control of generation, collection and transport, treatment, disposal and reuse of wastewater in a manner that is in accord with the best principles of public health, economics,...

the treatment facility of albourz industrial city was established in 1999 at the southeast of albourz mountain with an area of 200,000 square meters. currently, 40,000 cubic meters of industrial wastes are treated daily utilizing biological method of activated sludge up to the second phase without chlorination in this treatment facility. then, the discharged wastes are directed toward the lower...

Background and Purpose: Improper wastewater and solid waste management in rural areas could be a risk to human health and environment pollution. One percent of Iran’s rural area is connected to the wastewater collection network. Solid waste management in rural areas of Iran is mainly consisted uncontrolled dumping and open burning. The aim of this study is prioritization of wa...

The volume of wastewater generated by domestic, industrial, and commercial sources has increased with population, urbanization, improved living conditions, and economic development. The productive use of wastewater has also increased, as millions of small-scale farmers in urban and periurban areas of developing countries depend on wastewater or wastewater-polluted water sources to irrigate high...

background: hospitals generate relatively large quantities of wastewater that may contain various potentially hazardous ma­terials; therefore the proper management of hospital wastewater is essential. methods:   in this cross-sectional study, the quality and quantity of wastewater in the hospitals of tehran university of medi­cal sciences (tums), tehran, iran, were studied and the suitable meth...

In peri-urban areas in low-income countries, conventional centralized approaches to wastewater management have generally failed to address the needs of communities for the collection and disposal of domestic wastewater and faecal sludges from on-site sanitation. There are opportunities for implementing wastewater management systems based on a decentralized approach that may offer opportunities ...

Providing reliable and affordable wastewater treatment in rural areas is a challenge in many parts of the world, particularly in developing countries. The problems and limitations of the centralized approaches for wastewater treatment are progressively surfacing. Centralized wastewater collection and treatment systems are costly to build and operate, especially in areas with low population dens...
