Padre Dam Municipal Water District (USA) opened its Advanced Water Purification Demonstration Facility in late April of this year. The demonstration facility will use advanced water purification technologies to purify and test approximately 100,000 gallons of recycled water each day. The facility was designed to deal with California’s severe drought conditions by developing a new […]

Barriers to Water Reuse for Drinking Water in the US
It has been demonstrated that existing technologies for advanced water treatment can successfully upgrade wastewater to drinking water quality in large scale. There are installation for water reuse/water reclaim in California that are treating municipal wastewater to drinking water quality in volumes over 70 MGD. These technologies employed include membrane filtration, RO, UV and ozone. […]
San Diego Moves Forward with IPR Demonstration Employing Advanced Oxidation
San Diego City Council members approved a Water Purification Demonstration project using a indirect potable reuse (IPR) program. Implementation of an IPR would provide a significant new local water supply, while reducing the amount of primary effluent discharged to the ocean, helping the City avoid a $1.5 billion upgrade of the Point Loma Wastewater Treatment […]
Jamaica Considers Water Reclamation
Whenever there is a drought, Jamaican households go without water and crops yields are affected. There is also an increase in water-borne illnesses such as gastroenteritis. One method for overcoming the problems associated with occasions of drought in Jamaica is reclaiming water. Reclamation of water is the treatment or processing of wastewater to make it […]
Grey Water Reuse – A Low Cost Option for Sustainability
A recent paper published in the AWWA Journal (Olmos & Lodge, 105:2,February 2013, pp 41-42) discusses achieving zero water use and reasonable payback periods for a housing development in Davis California. Net zero water use as defined here is that annula water use equal annual rain fall. This would make the development sustainable from teh […]
Water Reuse Requires Multiple Barrier Approach
In previous posts we have talked about reuse of wastewater for drinking purposes including the feelings of Americans towards the use of wastewater for their water supply. In reality, many American’s already use wastewater as their drinking water source. If your drinking water plant is down stream of another cities wastewater plant, you are in […]
Australian Floods May Have Been Prevented by Water Reuse Schemes
The long Australian drought increase interest in Australia for people to talk seriously about recycling our sewage to use as drinking water. It is possible that if recycling schemes had been in place, the massive floods that followed last year might not have happened. There are two kinds of recycled water: ‘Indirect potable reuse’ or […]
MBR Ozone System for Water Reuse in Seafood Processing
Pescados Industrializados of Mazatlan, Mexico, a tuna cannery, has installed a new MBR system with down stream ozone treatment. The primary purpose of the MBR is to treat wastewater from the plant to comply with effluent regulations of the Mexican government. 30% of the effluent is further polished using ozone, AC, RO for reuse in […]
Orange County Reclamation Project a Model for the World
Water Factory 21 (WF21), Orange County Sanitation District (OCSD), was dedicated in a 1977 and transforms secondary municipal wastewater into water that exceeds drinking water standards. In 1991, the Orange County Water District (OCWD) was granted a California Department of Health Services permit to inject 100 percent reclaimed wastewater into a potable water aquifer without […]
Tokyo Wastewater Reclamation Process uses Ozone and Microfiltration
The Japan ozone Association in conjunction with the Water Re-Use Promotion Center, the Japan Water Works Association and the Japan Industrial Water Association held a seminar cover various issues related to ozone in water treatment with a focus on water reuse. A highlight of the meeting was a tour of a water reclamation projection where […]
