31. Lime Slaker System Reduces Operating Costs And Increases Sustainability At WTP 2/2/2017

    The West African City of Abidjan in Côte d’Ivoire has historically provided drinking water to its five million residents from water treatment plants that use hydrated lime systems. But because of the high content of carbon dioxide in the local groundwater, up to 160 ppm, setting the water to calcium carbonate equilibrium using hydrated lime was economically, operationally and environmentally challenging for the city of Abidjan.

32. Recognizing Ingenuity From Treatment Plant Employees 12/7/2016

    The Water Environment Federation’s Ingenuity Contest awarded treatment plant employees all over the country for their ingenuity in solving problems with what they had on-hand. Which clever fix could be used at your plant?

33. WTP Chooses A-758 Plus™ Lime Slaker Systems To Replace Existing Systems 12/6/2016

    The Albert R. Davis Water Treatment Plant (WTP) in Austin, Texas, is one of three water treatment plants supplying drinking water to the greater Austin metropolitan area. The plant was built in 1954 and has had multiple upgrades over the years, increasing its capacity to 118 million gallons per day (MGD).

34. Topeka WTP Installs Integrity A-758 PLUS™ Lime Slaker System To Replace Existing Lime Slaker 12/6/2016

    The Topeka Water Treatment Plant (WTP) — a 60 million gallon per day facility - serves Topeka, Kansas and surrounding areas. Built in 1945, the plant underwent several renovations with the most recent upgrading the plant to its current capacity in 1993.

    In 2015, plant officials decided to replace the first of the existing slakers and, after considering offers from several slaker suppliers, chose the A-758 PLUS™ paste-type lime slaker manufactured by Integrity Municipal Systems, LLC (IMS). Read the full case study to learn more.
