Supplying potable water to dense populations in developing countries is a perpetually daunting task for water service providers. Badlapur, India, part of metropolitan Mumbai, is one city stepping up its effort to supply its growing population with a 24-by-7 system. This will be a first for the country as currently no Indian city receives water round the clock.

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 historic city of St. Augustine, Fla., has relied on a surficial aquifer as the primary source of water for its 12,000 residents. Concerns about the city's future water supply and the impact of aquifer drawdown on wetlands in this coastal community led the city to develop a proactive plan for long-term water resource management.

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

Current best practices in wastewater reclamation facilities include the use of ultrafiltration or microfiltration membranes.

To achieve successful treatment of the water, one should know that no water is the same, every water is unique and should be treated uniquely.

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.

A 6.5 MGD Gulf Coast refinery began a Novozymes Biologicals bioaugmentation program to control effluent phenol in early January 2000. Effluent phenol concentrations often exceeded 0.3 mg/L before the bioaugmentation program began.
