As California suffers into its fourth year of a historic drought, a number of companies are offering water management technology as an important piece of the solution.

According to a recent USA Today article:

From nanotech to biotech, a range of companies is leveraging scientific leaps to profit from the preservation of what is inarguably the planet's most precious resource.

Writer Marco della Cava highlighted four companies that are innovating water management. These include Boston-based Cambrian Innovation which has created EcoVolt, a self-contained system that uses electrically active microbes to purify wastewater and generate energy-producing methane gas; Dais Analytic, Tampa, Fla., which produces ultra-fine nanotech membranes for wastewater purification; Ambient Water, Spokane, Wash., can harvest water vapor through the air through something similar to a giant dehumidifier; and HydroPoint Data Systems of Petaluma, Calif., which helps manage resources using big data collected through sensors and monitors

Another player in the market, the Mexican firm Jhostoblak Corporate, is aimed more squarely at households and industrial facilities, rather than agriculture. Jhostoblak's PQUA system separates and removes contaminants from wastewater and seawater. According to a profile in Water Online:

Along with time, the technology aims to save energy, relying on gravity to move materials when it's feasible. The system uses a combination of eight elements to break down other materials. "During the purification process, neither gases, odors, nor toxic elements that may damage or alter the environment, human health or quality of life are generated," the firm said in a statement.

And according to a recent press release from Alexandria Renew Enterprises:

... an innovative process to help clean wastewater will begin operations [in May]. The technology uses ANAMMOX microbes – also known as red bugs. AlexRenew is the first in the nation to design a full-scale sidestream deammonification system, and its system is only one of a few anammox deammonification systems in operation nationally.

Anammox exists in the natural environment and is safe for use in the wastewater treatment process. The application is used in Europe and Asia with excellent results. AlexRenew was an innovator in the field in the United States, conducting a pilot program in 2008 with DC Water, CH2M Hill, New York Department of Environmental Protection, and others.

The use of anammox bacteria has the potential to create up to 25 percent savings on energy and chemicals when compared to conventional wastewater cleaning processes. The process will also reduce the number of trucks delivering chemicals to the water resource recovery center located near historic Old Town Alexandria.

Would any of these options work for your agency?
