Growing population, industrialization, agricultural practices and urbanization have increased the water demand and hence the quantity of wastewater (ww). Availability of drinking water, including different components of daily per capita demand in developing countries, is becoming a serious issue to manage.

This study evaluates the capability of horizontal subsurface-flow constructed wetlands (SSF CWs) for treating pretreated swine wastewater as a function of contact time (CT) and type of macrophyte under the local conditions of Yucat

The quintessential example of large scale municipal wastewater reuse is the new Groundwater Replenishment (GWR) System in Orange County, CA. The system treats clarified secondary municipal wastewater effluent and, utilising microfiltration, reverse osmosis and advanced oxidation to produce 70mgd of reclaimed water.

The need of new approaches for wastewater management and environmental demands worldwide is challenging product manufacturers to develop advanced technology. Scientists, engineers and regulators are exploring innovative ways of testing new approaches and thinking about how to accomplish and manage decentralised wastewater treatment.

Water treatment & wastewater reuse - Case study.

The need of new approaches for wastewater management and environmental demands worldwide is challenging product manufacturers to develop advanced technology.

Ozone technology has been used for the past two decades or more. It is, however, only now that its use in wastewater treatment has been recognized.

Due to regulation and laws dealing with environmental protection, many new and existing facilities are required to install systems that eliminate or prohibit "open-loop" process waste streams containing contaminants. These systems may involve utilising chemical, mechanical, or biological treatment which commonly require cooling.

Adsorption occupies an important position among the unit operations in wastewater treatment. It exploits the ability of certain solids preferentially to concentrate specific substances from solution onto their surfaces. This paper deals with different adsorption systems as solution to wastewater problems.
