An Evaluation of Magnetic Ion Exchange (MIEX®) for NOM Removal
A new process for the removal of natural organic matter (NOM) was developed in Australia by Orica Watercare and South Australian Water Corporation. It employs a strongly basic anion exchange resin to remove NOM from water. In the first stage of the process, the (180 μm) MIEX® resin is mixed with the water to be treated and its small size encourages rapid removal of NOM. The resin beads also ...

Evaluating alternative aluminium sources for chloride removal from recycled cooling water
Chloride is important in promoting corrosion in cooling water systems, which leads to reducing the efficiency of heat transfer surfaces and shortening equipment life. Ultra–high lime with aluminium process (UHLA) is a potential new technology that has the ability to remove chloride and sulfate from recycled cooling water in addition to removing the majority of scale–forming compounds. The purpose ...

Reuse Treatment of Cooling Tower Sewage in Power Industry
For a long time, organic ultrafiltration membrane has been considered as an economical and effective traditional treatment method in the treatment of cooling tower sewage in power plants. In such applications with high pollution blockage tendency, the effect of organic membranes may be difficult to predict: more frequent chemical cleaning is usually required, resulting in longer downtime, lower ...

Limitations of the removal of cyanide from coking wastewater by ozonation and by the hydrogen peroxide-ozone process
The purpose of this study is to compare the efficiency of ozonation and the hydrogen peroxide–ozone process for the removal of cyanide from coking wastewater. The most efficient oxidation process is combined with coagulation–flocculation–decantation and lime–soda ash softening pretreatments. The oxidation in aqueous solution and industrial wastewater (at pH 9.5–12.3) by O3 was carried out ...

Sioux Falls, Verder Pumps - Case Study
The Sioux Falls Water Purification Plant in South Dakota USA, had always relied on gravity to feed slaked lime slurry to their softening basins. In 2009, the staff decided to give gravity a helping hand by trialing a pump to move the slurry more effectively. Lime slurry is a dense product to transfer with a high solid content of up to 35%. Due to the slurry’s abrasive nature which causes ...

A solution for scale removal case study
The Brookfields Restaurant chain consists of three large eateries located in and around Sacramento, Calif. Like many others, Brookfields Restaurants were equipped with water softeners to control lime scale on their hot water equipment, which consists of hot water heaters, dishwashers, steamers, coffeemakers and espresso machines. Even with the softeners, Brookfields Restaurants managers reported ...
