Dear Muthkrishna - Chloramines makes the issue worse by causing lead and copper corrosion, nitrification, and disinfection by-products that are 1000 times worse than those caused by chlorination according to researchers at the US EPA. ClO2 will not kill biofilms unless in a dose too high to consume. Super chlorinating at 200 ppm is not only toxic, its ineffective. Mechanical solutions such as pigging and relining pipes will damage the pipes and, once you are finished, the problem occurs again. Addition point of use devices or filters provides limited results but at a high cost that does not address that nearly 80% of corrosion in water pipes relates to microbiology. Mixed-oxidant products such as our own, Clearitas, are specifically engineered to remove biofilms and organic matrixed scale from the inside of water pipes (and anything the water touches) while under normal operations. There are several onsite generators that can be used to produce on-demand product, although a bulk, finished product is preferable because of the reduced operations issues. Ours is exceptional because of its patented strength and stability (over 12 months) and our proprietary ability to deliver it in volumes that can be used by the largest utilities in the world. Over 125 cities use Clearitas in the USA daily to remove and prevent bio-film build up and, when coupled with an effective flushing program, will reduce chlorine use by 50% +, reduce flushing, remove corrosion that reduces flows and consumes energy, while reducing disinfection byproducts. Look for mixed oxidant generators or send me an email and I can direct you to some alternatives. Dane
