Urbanisation and the subsequent increase in impervious land use generate increased urban stormwater which can be recycled viamanaged aquifer recharge (MAR) to supplement more traditional surface or ground water supplies. This paper compares the quality of stormwater from two urban catchments in South Australia to assess the risks, in accordance with the Australian Guidelines for Water Recycling...

It is the position of the Academy of Nutrition and Dietetics that all people should have consistent access to an appropriately nutritious diet of food and water, coupled with a sanitary environment, adequate health services, and care that ensure a healthy and active life for all household members. The Academy supports policies, systems, programs, and practices that work with developing nations ...

The last chapter elucidated the experimental setup and the factors influencing each unit of the large-scale seawater desalination process, with the reverse osmosis. This chapter deals with subjects such as the modeling of each unit of Sea water reverse osmosis (SWRO), the integration of these models to form an entire plant, and the future direction of the statistical modeling of the SWRO proces...

This research has determined the carbon footprint or the carbon dioxide equivalent (CO2 eq) of potable water production from a groundwater recycling scheme, consisting of the Beenyup wastewater treatment plant, the Beenyup groundwater replenishment trial plant and the Wanneroo groundwater treatment plant in Western Australia, using a life cycle assessment approach. It was found that the scheme ...

This report describes a simple chemical free method that was successfully used by a team of European and Indian scientists (www.qub.ac.uk/tipot) to remove arsenic (As) from groundwater in a village in West Bengal, India. Six such plants are now in operation and are being used to supply water to the local population (www.insituarsenic.org). The study was conducted in Kasimpore, a village in Nort...

Groundwater in Kabul basin, Afghanistan was assessed for its physical, chemical and bacterial components. Kabul basin is divided in to five hydro-geologic sub-basins, water from 50 wells whose depths varies from 9 meters -71 meters was analyzed. The pH, conductivity, total dissolved solids, temperature, chemical elements (cations and anion) and bacteriological content of the groundwater conform...

Simple water treatment devices are designed to treat small amounts of drinking water for home use. This study was undertaken to develop an iodine-releasing polymeric formulation and examine its potential as a domestic water purifier for untreated surface water. The antimicrobial tablet formulation was made from gum arabic (GA), poly(vinylalcohol) (PVA), ethyl cellulose (EC), and poly(vinylpyrro...

Surface waters to be used as resource for drinking water, waste water and sludge produced in treatment processes are very complex media containing soluble, colloidal and particulate matter. Apart from inert or dead matter the colloidal and particulate phase is mainly composed by organic bio-particles (viruses, bacteria, protozoa). Treatment processes like disinfection of potable water, hygienis...

In recent years, capital and operating costs of seawater desalination plants have decreased remarkably. However, production of potable water from seawater by reverse osmosis membrane desalination remains 2 to 3 times the cost of desalting brackish water, reclaiming wastewater, or importing fresh water even over long distances. In addition, rejection of boron by seawater RO membranes is generall...
