Abstract
The present invention provides a novel process for the removal and recovery of penicillin and organic acids from process streams and waste waters. The process of the present invention utilizes a combination of a supported liquid membrane (SLM) and a strip dispersion to improve extraction of the penicillin and organic acids while increasing membrane stability and reducing processing costs.
