The biologically enhanced carbon process is an option for many water utilities.
Mention the name of this place and people will conjure up a variety of impressions. There's Niagara Falls the honeymoon capital of North America-or at least it used to be. Then there's the scenic wonder of the Falls themselves, the famous Rainbow Bridge, and the touristy but interesting character of the towns on either side of the Falls and the massive downstream gorge-Niagara Falls, New York and Niagara Falls, Ontario. How about the '50s movie, Niagara, with Marilyn Monroe?
Designed and built in the '70s, broken down in the early '80s, the advanced wastewater plant is a success story in the '90s
A case study describes a full-scale UV disinfection system.The summer floods of 1993 in the Midwest were driven by repeated rains which deluged the region from Minnesota to Missouri. The flood crest on the Mississippi River was 46 feet above normal at its high point, and three feet above the highest ever recorded. For over three months the people of the region had to cope with the problems accompanying the swollen rivers, broken levees and inundated land areas.
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.
A New York State town developed a water treatment plant which uses dissolved air flotation and ozone disinfection to ensure meeting anticipated tighter regulations
A new water treatment plant was designed for the future with quality, quantity and regulations in mind.
Evaporation is being considered as an alternative process in an increasing number of wastewater treatment applications. It can be effective for concentrating or removing salts, heavy metals and a variety of hazardous materials from solution. Also, it may be used to recover useful by-products from a solution, or to concentrate liquid wastes prior to additional treatment and final disposal.
The recovery of valuable materials or separation of hazardous materials from wastewater flows can sometimes be accomplished with evaporation technology
