Title:Carus Corp. Water Conservation through Softener Feed Water Reduction
Author(s):Moshage, Tom
Subject(s):water reuse

Abstract:Tom Moshage - Senior Process Development Specialist/Project Engineer, Carus Corporation in LaSalle, Illinois. Founded in 1915, Carus Corporation is an environmental services company located in LaSalle, Illinois, that manufactures a range of products for municipal and industrial markets. Our site currently uses approximately 1,360 gallons of water per minute daily, which is equivalent to 1,958,400 gallons a day or 675 million gallons a year, based on 345 days of operation. We are being charged a rate of 0.798 dollars per 100 cubic feet of water used, including the city’s 5% utility tax. The estimated water cost for 2014 was 720,763 dollars. We have been tasked with coming up with a water reduction plan to reduce our water usage. In 2015, we began a new water contract with the city that increases our water usage rate to 1.145 dollars per 100 cubic feet. If we continue to use water at our current rate, 2015’s total water cost will be equivalent to 1,033,725 dollars. This is an increase of 312,962 dollars at our current water usage. Our goal was to develop a water reduction plan to reduce our current usage by utilizing spent non-contact cooling water from our crystallizer hot well to feed our water softeners in the boiler house. Previously, we used raw city water to feed the water softeners, which consume approximately 100 gallons of water per minute. Factoring in the increased cost of water in our new contract (adding 312,962 dollars per year), we saved 86,600 to 100,200 dollars per year by reducing our water usage by 56.6 to 65.5 million gallons.
