- Summary
-
A reverse osmosis pilot plant was operated on both primary and secondary effluent and the results compared. Data indicated that high axial feedwater velocities were necessary to prevent membrane fouling. The main substances causing fouling were suspended particulates, inorganic salt precipitates, and dissolved organic matter, as well as some other substances which are unknown at this time. Suspended particulates were flocculated, settled, and filtered out of the wastes, inorganic salt precipitation was controlled by pH adjustment, except in the presence of calcium sulfate, and dissolved organic matter can be removed by biological treatment. Cleansing the membrane with an enzyme-active laundry pre-soak formulation proved beneficial for both wastes.
