In addition to providing 15 minute chemical oxygen demand (COD) results and biochemical oxygen demand (BOD) estimates, the PeCOD® Analyzer measures natural organic matter (NOM) in fresh and treated drinking water. The PeCOD® Analyzer does what no other technology has done before. It quickly and safely measures oxygen demand and the associated oxidative changes in organic matter in fresh and treated drinking water, at low concentrations and without the use of hazardous chemicals. A new ASTM International...
Wastewater Deodorization: The formation of hydrogen sulfide often poses a problem for municipal wastewater treatment. Chlorine dioxide, a powerful oxidant, can be effectively used to control noxious, irritating, or pungent odors from many operations. Moreover, its unique selective properties permit more efficient application at a lower dosage and cost than chorine, hypochlorite, permanganate peroxide or ozone.
Potable mixing & treatment for the world`s largest projects: In certain parts of the United States and across the world, huge, 30 million gallon to 80 million gallon to 100+ million gallon potable water storage reservoirs are becoming more and more commonplace. The question isn`t so much can we help maintain water quality in reservoirs like these.
Most activated sludge systems have two things in common... Insufficient mixing which leads to poor solids suspension, poor processing, and potential violations and Excessive energy use & cost trying to accomplish item #1. There are other challenges too of course. Odors need to be kept below the "neighbor noticing" threshold. Issues with nitrification / denitrification can easily become large permitting problems. And let`s throw in chlorination / dechlorination and THM removal in there for good measure.
Problem: Drinking water plants that use chlorine for disinfection must ensure organic matter is removed before chlorination to limit the formation of harmful disinfection by-products (DBPs), most commonly Trihalomethanes (THMs) and Haloacetic acids (HAA5).
Ozone is a very effective alternative to chlorine and other chemicals as a disinfection agent in swimming pools. Ozone can safely prevent the formation of chlorine byproducts, such as chloramines and trihalomethanes which are potentially carcinogenic.
By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the...
The growing demand placed on the world’s water, in combination with more stringent water quality regulations, have placed unprecedented demands to provide safe, reliable and aesthetically pleasing drinking water. Air stripping is an effective way of removing volatile organic chemicals (VOCs) from contaminated water and is commonly used for this application. Air stripping systems mix air with a water supply with the goal to generate the largest possible air-water contact area so that VOCs and dissolved...

All surface waters contain varying amounts of naturally occurring organic acids. The most commonly encountered being tannic and humic. These substances have varying molecular weights and varying amounts of carboxylic functionality. There has been much interest in the removal of these substances from drinking water supplies due to their tendency to form THM`s when chlorinated. They can be removed effectively by use of anion exchange resins operated in the chloride cycle. Because the organics can be removed by...
