Innovative Methods in Wastewater Disinfection

Wastewater can have several meanings, depending on the industry or application. Blow down from cooling towers is considered wastewater; leachate recovery water in greenhouses contaminated with pathogens can be considered wastewater; and water processed in sewage plants is definitively considered wastewater. Finding alternative methods to disinfect water before it is introduced back into the ecosystem or to disinfect reclaimed water, has always been a challenge.

Reverse Osmosis

In 1954, the U.S. Navy launched the Nautilus, the first nuclear powered submarine. Using nuclear power to generate steam to drive a submarine’s propulsion system allows the vessel to stay under water for long periods of time without refueling. Nuclear power is now the primary method of generating power for propulsion for the U.S. Navy’s fleet of fast attack and ballistic missile submarines.

the magnolia power project

The Magnolia Power Project is a state-of-the-art, combined-cycle electric generation facility built on four acres of Burbank Water and Power (BWP) generation station complex adjacent to Magnolia Boulevard in Burbank, Calif. On June 10, 2003, the mayors and utility officials of the six participating cities joined together with Southern California Public Power Authority officials for a Magnolia Power Project groundbreaking ceremony to commemorate the start of the on-site work.

Membrane Technology

Drinking water quality issues at the residential level are now as sensitive as ever. As the nation’s population continues to grow, the associated use of chemical products and waste generation rises accordingly. As a result, an increasing variety of contaminants are regularly released into the nation’s water sources, eventually making their way into the drinking water supply.

Desalination

Aging facilities, increasingly strict regulations and growing communities are resulting in the need for significant investment in new drinking water infrastructure. As these demands place strain on the capacity of existing treatment systems, many municipalities are turning to membrane filtration to treat their sources of surface and ground water.

Commercial Drinking Water Systems

When designing a commercial drinking water system using ultraviolet (UV) light for disinfection, you will need to know the local regulations, how to determine flow rates, what options may be required and whether you need pre-treatment. When speaking about commercial establishments, I am referring to restaurants, daycare centers, schools, hospitals, parks and other entities that serve the public.
