Technology Investigation: UF & CapDI |
HMGA Water Project collaborated with two technology providers to test the feasibility of their systems at treating vegetable washwater. An ultrafiltration unit from Newterra was followed by capacitive deionization from Voltea at this on-site pilot project. A summary of the test and results can be found in the article below.

Ultrafiltration (UF) is a method of filtration that removes any particles larger than 0.04 microns. The wastewater passes through specially designed membranes under pressure. The membranes capture unwanted material and will need regular cleaning to prevent fouling. Some UF systems will have automatically cleaning cycles that greatly reduce the amount of maintenance required. UF has many applications and may be able to effectively remove muck soil particles and dissolved nutrients from vegetable washwater. The HMGA Water Project is working with Newterra, a Canadian engineering company that specializes in wastewater treatment. Newterra provided a UF pilot unit that was placed after a settling tank system at vegetable washing facility.
