Water professionals are seeking innovative approaches to address water supply challenges associated with population growth, drought, and environmental protection.
Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation.
Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.
The installation of a new water treatment system at the Plum Creek Water Purification facility in Castle Rock, Colo. is enabling the town to treat and deliver renewable surface water to residents and businesses.
The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site. The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.
When a series of water crises in 2014 disrupted conventional utility services in the coastal Argentine city of Caleta Olivia, the city needed a way to ensure an uninterrupted water supply.
The Chicago area is served by a combined sewer network that carries both raw sewage and storm water.
A $12-million public and private research project, the Nebraska Innovation Campus (NIC) in Lincoln, Nebraska, is a combined effort of the University of Nebraska Lincoln (UNL) and the private sector and aspires to be the most sustainable research and technology campus in the United States.
In parched California, Nestlé USA is undertaking numerous measures to conserve water in its food and beverage operations across that state. Four years into a significant drought in the nation’s most populous state, California government officials recently began initiating mandatory controls on water usage for businesses, farms, and residents. Nestlé is hoping to stay ahead of these developments and allay pressure from environmental groups that criticize increasing use of bottled water, one of the company’s major product lines.
With diminished rainfall, a depleted aquifer basin, near-empty recharge ponds, and an earthquake-vulnerable aqueduct system, the Santa Clara Valley Water District (SCVWD) in San Jose, CA, required additional water supplies to maintain regional economic vitality for its growing community.
Biological Nutrient Removal (BNR) is allowing many wastewater treatment plants to achieve extremely high effluent quality. Still, for some applications even the most advanced BNR processes can’t address concerns with trace organics, pharmaceuticals, and other endocrine disrupting compounds (EDCs).
I was at a funeral recently and when the internment got to the “ashes to ashes, dust to dust” part, specifically at “dust you are and to dust you shall return,” it occurred to me that nothing could be further from the truth.
Wastewater facilities have transitioned from “sewage treatment” to “wastewater treatment”, then to “water reclamation”, and now have progressed toward “water resource recovery facilities” (WRRFs).
The power sector looks to zero liquid discharge and taps municipal reclaimed water as a water reuse strategy.
In 1943, Thomas Watson, president of International Business Machines (IBM) said, “I think there is a world market for maybe five computers." At the time, a single computer was the size of a large room.
A water technology expert tackles high-profile and important topics currently affecting municipalities, industry, and the community at large.
Reverse osmosis is one of the most energy-intensive, and therefore costly, steps in wastewater treatment. A newly developed nanofilter may change that.
