WEMCO DEPURATOR Unit

Maximize efficiency with froth flotation

All DEPURATOR units use the froth flotation process to remove oil and solids from produced water. The key component is the mechanical aeration assembly that constantly disperses gas bubbles into the produced water. The oil, solids, or both adhere to the bubbles and then rise with them to the surface of the cell, forming a froth. Because the contaminated water and the floating froth are constantly being subjected to reintroduced gas, it is impossible for the floating materials to settle into the now-cleaner water below.

Depending upon the type of DEPURATOR unit, the froth is removed either by mechanical or hydraulic skimmers. The water then moves into the next cell, where the process is repeated. In the final stage, the now-cleaned water goes through a degassing discharge chamber and exits the unit. Units can be configured with two to five cells to achieve application requirements.
