Well Water Treatment: Ozone Helps Solve Water Problems at Bassi Ranch

An analysis of the raw well water (Table 1) shows a pH of 7.9 and 30 color units with >20 mg/L hydrogen sulfide, 5.6 mg/L iron and 0.6 mg/L manganese. Odor was detected at 10 threshold odor number (TON), indicative of the high hydrogen sulfide levels. To meet these water problems head-on, the homeowners formed the Bassi Ranch Mutual Water Co. in 1992.

Ozone for Water Treatment Gains Acceptance

Dealers of water enhancement products are increasing ozone sales rapidly, while finding sales of chemical-oriented products are less attractive to their clients. The advantages of ozonated water are becoming better understood and easier to sell. As consumers demand a better water supply, the use of chemicals will continue to diminish while the use of ozone increases.

DAF & Ozone Eliminate Quality Woes, Meet New Regs

When a town meeting in New Castle, New York, prompted local government officials to take citizen complaints about water quality seriously, they initiated a lengthy multi-step project to fix the problems. They could not have known then, in the early '80s, that their decision to proceed was timely. The water system improvement program they embarked upon anticipated some of the key regulatory requirements put in place years later, and solved problems of quality and quantity that arose as a result of the growth and development of the town and its surroundings.
