A container for releasing a microbiocide component into a liquid composition susceptible to unwanted microbial growth (LCMG) includes a LCMG impermeable casing separate and apart from an internal combustion engine filter housing, and having a hollow interior and at least one opening. A microbiocide component, for example, at least one LCMG-soluble microbiocide, as the only active material located in the hollow interior. At least one liquid permeable element, for example, a membrane member, is provided at or near an opening in the casing and is effective to provide for release of microbiocide component into the LCMG. Methods of releasing microbiocide component into LCMGs are also provided.

Controlled release of microbiocides

Containers for controlled release of an additive composition into a liquid composition include a liquid impermeable casing having a hollow interior, at least one opening and a membrane component secured to the casing. Methods of releasing additive compositions into liquid compositions are also provided.

A controlled release additive composition for use in aqueous coolant systems is disclosed and comprises a core containing at least one additive component and a polymeric coating including one or more defined polymers substantially surrounding the core. The controlled released additive composition slowly releases the additive component into the aqueous coolant of an open, circulating cooling water system, thereby delivering an effective concentration level of the additive component over an extended period.

An apparatus and method for the monitoring and measurement of chemical and/or biological deposition in heat exchangers and other fluid processing vessels. The new and original sensing system includes at least two hollow fluid vessels conductively mounted across a constant heat transfer path. Thin film heat flux sensors are attached to a heat transfer surface of the vessels in order to measure changes in differential heat flux that occur when deposition begins to accumulate in the vessel. In this way, it is shown that differential heat flux measurements can be used to detect and measure the early onset of chemical and/or biological deposition.
