In this review, introduction, chemistry, uses, sources, effects of copper and copper pollution and its removal from …
An analytical review of the interceptor plan for cleaning Yamuna. CSE has closely scrutinised the interceptor plan and found this hardware plan to be a complete waste of money. The river will continue to remain dead despite the massive investments planned during 2009-2012. he interceptor project is projected by the …
This study presents adsorption performances for Carbamazepine, Propyphenazone and Sulfamethoxazole using polymer resin, Lewatit VP OC 1163. Adsorption capacities followed: Carbamazepine>Sulfamethoxazole>Propyphenazone. Lewatit VP OC 1163 showed a larger adsorption for pharmaceuticals having low solubility, with Freundlich adsorption parameter, Kf, reaching 46.068 for Carbamazepine.
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. To fight with growing water stress, reclamation and reuse …
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.

health Cracking the capsule Every year a million people, mostly aids and transplant patients, are killed by a disease called cryptococcosis, symptoms of which include chest pain, dry cough, abdominal swelling, headache and blurred vision. This disease is caused by the deadly fungus Cryptococcus neoformans which attacks immune systems that …
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.
Recent study on ground water quality in Lakshadweep Islands shows that groundwater in these islands are mainly contaminated by domestic sewage and sea water intrusion. Contamination by domestic sewage is attributed to tank used by the islanders for sewage disposal. In the present study, an Anaerobic Single Baffled Reactor is …
EWT UNR TM MBR system incorporates flat-plate, micro filtration membranes. Since 1990, many wastewater treatment plants have been built based on this technology around the world.
Sand filters treat most of our drinking water supplies, and they are the most common filtration technologies used for waste water, sewage effluent, and grey water recycling and water treatment in general.
The focus of this publication is efficient water use in urban and domestic environments and decision-making about sustainable development of human settlements. The book is written as a Sourcebook, highlighting essential questions that will have different answers in different situations. By looking at water use efficiency within the context of …
MARGAO, NOV 12 Foul odour emanating from the sewage treatment plant brought PWD Minister, Churchill Alemao to the plant site at Sirvodem-Margao on Wednesday evening.
