Start-up method for filtering membranes to remove glycerin

摘要

In a process for biodegrading glycerin used to store or preserve membranes, water in a tank is inoculated with glycerin digesting microorganisms. The water is aerated to support growth of the microorganisms. The water is filtered through the membranes and the filtrate returned to the tank. The glycerin is rinsed out of the membranes and biodegraded in the tank. The process may be performed in-situ in a water or wastewater treatment plant as part of the start-up procedures for the plant.
