Continuously Regenerated Greensand for Iron and Manganese Removal
Hackettstown, New Jersey, has a population of 6,000 persons. Periodically, the town's usual water supply proved inadequate, and it was felt that a new emergency well, 153 ft deep, would solve any problem of water shortage. Unfortunately, the well supply contained 13 ppm iron and 1.5 ppm manganese. The well water could not be introduced into the town's water system unless the high iron‐manganese content was reduced. In 1961, after making extensive field tests with a pilot plant, it was decided to install a pressure‐type system in which processed greensand would be regenerated continuously with potassium permanganate. The proposed filter plant was to have a normal flow of 500 gpm and a maximum flow of 700 gpm. Both the effluent and the CR (continuously regenerated) greensand filter plant were approved by the New Jersey department of health. The results are well below the maximum tolerances of USPHS and the proposed amended standards of the New Jersey state board of health.
