IMS is a US engineering company which designs and supplies pre-assembled, process solutions for the water and wastewater industry. The new system is compact and modular and it can be quickly installed to safely produce LAS.
The use of liquid ammonium sulfate is increasing as a safe, economic alternative to aqueous ammonia. Unlike aqueous ammonia, LAS has an indefinite storage life, is odourless and non-toxic. The IMS two-tank upflow saturator and feed system technology can reliably and economically produce a 40% liquid ammonium sulfate solution from solid ammonium sulfate for approximately US $3.00 per gallon.

The custom-designed, modular LAS feed system for water processes is pre-assembled, factory-piped, wired and tested, with low installation costs and a typical installation time of only two hours. The compact design is environmentally friendly and ensures that safety is a top priority. The fully contained system eliminates any risk of liquid ammonium sulfate solution entering floor drains.
