GAC Value Exceeds Expectation
Untitled Document Summary: It appears that the time span in which GAC will remove THMs can be measured in months - perhaps even years - at the Davenport, Iowa, water treatment facility. Research by EPA, the American Water Works Association, and other groups on the adsorptive capacity of granular carbon for trihalomethanes had indicated that removal of THMs by ...

A Simple Method to Reduce Disinfection By-product Formation
The formation of disinfection byproducts (DBP) during drinking water production has long been of concern toauthorities and consumers alike. Although most disinfectants form unwanted DBPs there is particular concern withchlorine disinfection as a variety of chlorinated compounds are formed with possible adverse health effects, includingtrihalomethanes (THMs). Strategies for controlling THM ...

Get Custom THM Stripping Without Breaking the Bank
To limit costs, consider site-specific parameters if installing off-the-shelf trihalomethane removal systems. DISINFECTION by-product (DBP) regulatory compliance requires public water systems to achieve total trihalomethane (TTHM) levels of 80 ug/L (ppb) or less for a locational running annual average throughout a community. Often a water treatment plant's most cost-effective approach is to ...

Trihalomethane reduction in drinkable water by controlled chlorination and use of hydrogen peroxide
The reduction of trihalomethane (THM) formation in the water treatment process by a controlled chlorination of ammonia and successive quenching with hydrogen peroxide has been studied. The optimum values of the process parameters have been determined with a calculation programme that makes use of the kinetic constants determined with the water to be treated. The obtained data have been verified ...
