Abstract: Biocide can be controllably added to a feed stream for a membrane. The membrane can separate the feed stream into a purified permeate stream and a concentrate stream containing contaminants from the feed stream. In some examples, a charge neutral biocide is introduced into the feed stream at a first addition rate. The concentration of the charge neutral biocide in the permeate stream is measured to provide a measured concentration of the charge neutral biocide in the permeate stream. The addition rate of the charge neutral biocide can be adjusted based on the measured concentration of the charge neutral biocide in the permeate stream to introduce charge neutral biocide into the feed stream at a second addition rate different than the first addition rate.

Abstract: A fluorometric monitoring technique can be used to rapidly evaluate the efficiency of an osmosis membrane. In some examples, the technique includes injecting a bolus of fluorescent tracer into a feed stream. The tracer may be introduced for a period of time less than what is required for the tracer to reach an equilibrium concentration in the permeate stream. The feed stream and the permeate stream may be fluorometrically analyzed to determine a flow rate-independent cumulative-time concentration of the fluorescent tracer in the both streams. The efficiency of the osmosis membrane can then be determined based on these flow rate-independent cumulative-time concentrations.
