In potable water treatment, the volume of granular activated carbon (GAC) per filter is a major issue, both in commercial agreements and in filter design and operation. Once exhausted, the GAC is typically regenerated by thermal reactivation.

Workers at Chilean copper-gold mine port facilities will soon be quenching their thirst with drinking water from an innovative new seawater reverse osmosis (RO) system supplied by Koch Membrane Systems (KMS).

Bacterial isolates from water and sediment samples from freshwater, estuarine and marine regions were tested for their growth in the presence of different concentrations of arsenic.

Despite the overwhelming advantages of mechanic villages, their heavy metal pollution of soil due to poor waste management is causing serious ecological and public health concerns.

This review presents removal of three major anionic contaminants (arsenic, phosphate and fluoride) in water by adsorption/precipitation method using both synthetic and natural materials. A discussion is also made on interfering co-radicals (silicate, sulphate, nitrate, bicarbonate, chloride, etc.)

The continued high cost of fresh water and environmental concerns are causing more industrial plants to explore wastewater reuse options. Many facilities are finding it can be more economical to reuse wastewater from specific process areas or from sources outside the petroleum refining or petrochemical facility that it is to reuse wastewater from centralized wastewater treatment plants.

Worldwide, cities and townships are facing many complex wastewater treatment issues. Although centralized sewers are seen as a preferred solution to wastewater problems, areas with centralized sewers discharding to surface waters, have been identified as source of many pollution problems. Lack of sufficient, even basic treatment is a risk to public health.
