The liquid ammonium sulfate feed system from Integrity Municipal Systems is designed to be a safe, economic alternative to aqueous ammonia in municipal water and wastewater applications. The standard LAS saturator and feed system is 5 feet 6 inches long, 3 feet 8 inches wide and 5 feet 8 inches high.

“The difference between our system and other LAS feed systems for chloramination is the capacity to produce the chemical on site,” says Kingston Leung, IMS product manager. “Our system allows you to purchase the salt, store it and produce the solution. In some places LAS is widely used and you can get it quite cheaply, but there are other locations where it’s difficult and expensive to purchase LAS solution.”

The IMS system can produce 75 gallons of liquid ammonium sulfate per salt fill. LAS has an indefinite storage life, is odorless and nontoxic.

“The purpose of this system is to provide ammonia downstream of chlorine, and by doing that you produce chloramines for disinfection,” Leung says. “This is a system that you would use as part of a chloramination disinfection system. Any plants of adequate size that already use chloramination or are planning to use chloramination could use this system.”

Unlike conventional one-tank saturator systems, the two-tank system design consists of separate saturator and solution tanks, reducing suspended solids in the solution tank and minimizing the chance of the metering pump plugging. The upflow saturator design including automatic, preset saturator operation ensures complete saturation, high degree of reliability and low maintenance.

“The system is completely automatic,” Leung says. “The saturator tank is where the salt goes in. As water flows through the saturator tank and up through the bed of salt, the salt dissolves, producing a near-saturated solution. As the water flows through, solution overflows from the saturator tank into the solution tank, providing a solution that can be dosed into the waterline.”

The fully contained system eliminates the risk of liquid ammonium sulfate solution from entering floor drains. In the event of a leak in the secondary containment, a switch activates, notifying personnel.

A skid-mounted FRP enclosure including lighting, ventilation fan and breaker panel is available for protection from the environment in outdoor and remote locations. 858/486-1620;
