Opis:: The paper reveals the results of the research on the reverse osmosis recovery of zinc from galvanic electroplating. The pilot plant tests were performed in an electroplating shop. Raw washings were concentrated with a spiral wound 2.5x40" module with a composite polymeric membrane. The research tests have proved that the proposed RO process enables successful concentration of the non-ferrous metal in raw washings. The retentate of the RO process has contained about 96% of the metal previously wasted in washings discharged to the environment. The retentate can be recycled to the mother electroplating process. The permeate of the RO process can be recycled to the washing system of the electroplating shop.

Opis:: The efficiency of enzymatic depolymerization in a membrane reactor was investigated. The model analysis was performed on bovine serum albumin hydrolysis reaction led by three different enzymes, for which kinetic equations have different forms. Comparing to a classic reactor, the reaction yield turns out to be distinctly higher for all types of kinetics. The effect arises from increasing (thanks to the proper selectivity of the applied membrane) the concentration of reagents in the reaction volume. The investigations indicated the importance of membrane selectivity election, residence time and at non-competitive inhibition the substrate (biopolymer) concentration in feed stream. Presented analysis is helpful in these parameters choice for enzymatic hydrolysis of different biopolymers.
