The proportional feed system from Blue-White Industries is designed to maintain constant chemical injection to water flow ratio regardless of changes in the flow rate or pressure.“In most water treatment applications you’re going to be injecting a chemical into a flow stream. And that flow stream is typically not a consistent flow rate,” says Bill McDowell, sales engineer, Blue-White Industries. “Coming out of a water well, the flow rate might be consistent if you have a well pump that is operating at, let’s say, 100 gpm. Typically you can put a ‘dumb’ pump in there and set it for a
