Blue-White Industries highlights its Chem-Feed MD1 and MD3 chemical metering pumps as well as its latest CO2 Feed System for pH adjustment at WEFTEC 23 in Chicago.

Blue-White Industries highlighted its chemical metering solutions at WEFTEC 23 in Chicago to assist water and wastewater utilities with chemical dosing applications for water and wastewater treatment in their plants.

CO2 Feed System

The Blue-White CO2 Feed System safely and effectively maintains pH control for water and wastewater systems. It has a NEMA 4X enclosure and a 1-year warranty


The Chem-Feed MD1 is a multi-diaphragm metering pump. A major issue for metering pumps occurs when air is trapped in the piping of the pump, causing vapor lock. The MD1 uses a degassing valve to ensure air can be purged from the system in the event it is entered. As a result, the pump cannot vapor lock. The MD3 is a larger version of the MD1 for applications at greater scale.
