The Oak Ridge WTP is decommissioning the existing 1943 plant that provides the city’s drinking water and constructing a new facility to treat over 45 million litres of water per day.
WD News: A Qdos 60 PU peristaltic pump head from Watson Marlow Fluid Technology Solutions has completed three years of maintenance-free operation without any leaks in a trial at the City of Oak Ridge water treatment plant (WTP) in Tennessee, US.
The trial began in May 2020 with the prototype Qdos 60 peristaltic pump with ReNu PU (polyurethane) pump head dosing poly aluminum chloride, a polymer used in water purification which enhances flocculation and coagulation of pollutants. Throughout the period, there has been no need to stop production for maintenance downtime or to fix a polymer leak – which is expensive and time-consuming to clean up.
The Qdos 60 ReNu PU pump head is specifically designed for polymer dosing. The city of Oak Ridge water treatment plant is using seven Qdos peristaltic pumps to feed chemicals such as 20% sodium permanganate, 12.5% sodium hypochlorite, fluorosilicic acid, and a poly/orthophosphate corrosion inhibitor to the plant’s current coagulant.
The new plant will be ready to provide water by spring 2025 and will be using ten Qdos 60 pumps for a variety of chemicals for water treatment such as hydrogen peroxide, sodium permanganate, and fluoride. In addition, WMFTS will also be providing two Bredel Apex 15 pumps for sodium hypochlorite.
