A European project is helping to improve the efficiency and safety of ozone use in the management of water quality in aquaculture. Ozone is a great tool for the removal of fine particles and dissolved organics in fish tanks when used with a Recirculation Aquaculture Systems (RAS). Research shows that using ozone for water treatment […]

Ozone Laundries Save Energy, Water and Money
The City of Santa Rosa conducted a pilot rebate program for hotes and commercial laundry facilities to use ozone. It was part of a larger state wide program determine the amount of energy consumed by various water using applications. Specifically the program tried to quantify the water and energy savings assocaited with ozone laundries versus […]
Sequester to Affect Water Funding According to the EPA
The Safe Drinking Water Act and the Clean Water Act include revolving loan funds to help states finance drinking water purification and sewage treatment facilities—both of which are essential to the country’s public-health infrastructure. The Environmental Protection Agency reports that: Reductions under sequestration would impact states’ ability to meet drinking water public health standards and […]
Maersk Uses Ozone UV for Ballast Water Treatment
A.P. Moller-Maersk (Maersk) has indicated that ballast water treatment system (BWTS) based on mechanical filtration and disinfection with UV and ozone represents a good solution for container vessel retrofits. Both ozone water treatment and UV are excellant disinfection technologies for a wide range of applications. Maersk says that the containerization of the BWTS is a […]
Emmons County ND Uses Ozone Pretreatment for a UF/RO Drinking Water Treatment Plant
The South Central Regional Water District utility knew that water from these wells contained high levels of dissolved solids, hardness, and sulfates, as well as arsenic content beyond the safety standards established by the Environmental Protection Agency (EPA). A treatment solution was developed ozone pretreatment, ultrafltration (UF) and reverse osmosis (RO) to treat nearby Missouri […]
Muttenz Switzerland to Treat Groundwater with Advanced Oxidation
The groundwater in Muttenz, Switzerland will be purified using a combination of advanced oxidation, adsorption and ultrafiltration. The water is subject to organic trace substances and occasionally impacted by Rhine filtrate. Difficult to treat compounds will be oxidized using ozone and hydrogen peroxide. The ozone and peroxide react to form hydroxyl radicals that are fast […]
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 […]
Ann Arbor Michigan Uses Ozone for Primary Disinfection
Ann Arbor’s Drinking Water Treatment Plant’s primary source of water comes from the Huron River. Ann Arbor is one of only seven facilities using an inland river as a drinking water source in Michigan. About 85 percent of the water comes from the river, while 15 percent comes from wells located at the city’s airport. […]
Ozone Disinfection of Water Mains
Before a new water main or one that has recently under gone repair can be placed back into service, it must be flushed and disinfected. The conventional approach is to use high concentrations of chlorine for an extended period of time to kill the bacteria living in the biofilms attached to the water main surface. […]
Study Shows Electrolysis and Volatilization Can Mitigate Bromate Formation in Drinking Water
A recent study in the Journal Ozone Science and Enginnering has shown that electrolysis followed by volatilization can remove Br from drinking water and as a result lower the formation of bromate from ozone water treatment. This is an important issue since a large number of water sources contain Br ion. Ozone can react under […]
