Kruger Starts Up a Cutting-Edge Water Treatment Plant to Provide Drinking Water in Colorado
18 january 2016Kruger Inc., the Veolia business unit that specializes in municipal water and wastewater treatment solutions in the United States, recently started up a ground-breaking treatment process at the Rueter-Hess Water Purification Facility in Colorado. The Kruger Opaline process is the first of its kind and part of a drinking water treatment expansion for the Parker Water and Sanitation District (PWSD). The drinking water plant utilizes ACTIFLO® Turbo, ACTIFLO® CARB, and Kruger Ceramic Membranes (KCM) to produce potable drinking water for PWSD’s customers.
The primary processes at the Rueter-Hess Water Purification Facility are ACTIFLO Turbo
for enhanced coagulation, ACTIFLO CARB
for enhanced organics removal via the use of powdered activated carbon (PAC), Kruger ceramic microfiltration membranes (KCM) for filtration, and sodium hypochlorite for disinfection. The plant is designed to treat ten million gallons of water per day (10 MGD) to meet state and federal drinking water standards.
The water from PWSD’s Rueter-Hess Reservoir has a number of treatment challenges, including turbidity, microorganisms, algae, iron, manganese, and high dissolved organic carbon (DOC).
At the heart of the treatment process is the highly efficient ACTIFLO CARB process, in which PAC is utilized in a proven Kruger system. The system optimizes the required PAC dosage while minimizing the DOC in the treated water. Keeping DOC to a minimum is one of the main treatment goals of the water plant, since DOC combines with chlorine, in this case from the sodium hypochlorite, to form disinfection byproducts (DBPs). DBPs can be a long-term health concern and are regulated by the EPA. The Kruger-supplied process minimizes DBPs during treatment while making the treatment process efficient in its use of treatment chemicals.
Downstream of the ACTIFLO CARB process are the first ceramic membranes in North America. KCM features monolithic internal pressure-type elements, each with 269 sqft of membrane surface area and a 0.1 µm pore size to effectively filter turbidity, bacteria and pathogens. These state-of-the-art membranes were selected due to their high mechanical strength and long term reliability.
The combined treatment train – ACTIFLO Turbo, ACTIFLO CARB, KCM, and disinfection – provides cutting-edge treatment to make the Rueter-Hess Water Purification Facility an efficient, safe, and technologically advanced facility for the customers of PWSD.
