Abstract: A method of cleaning a cooling water system is disclosed. The method may include contacting a cooling tower fill with a composition that may include a surfactant and an additive selected from an oxidizing agent, an acid, and any combination thereof when the cooling water system is off-line. The method may include contacting a deposit in the cooling tower fill with the composition. The oxidizing agent may be hydrogen peroxide, sodium hypochlorite, chlorine dioxide, ozone, sodium hypobromite, sodium or potassium permanganate, or any combination thereof. The surfactant may include a C8-C10 alkyl polyglycoside and a C10-C18 alkyl polyglycoside.

Abstract: The invention provides methods and compositions for the protection of a membrane from both biofouling and from damage caused by a biocide. The invention utilizes PAA as both a biocide and as a reducing agent for other oxidizing biocides. This is especially beneficial because without the invention one would be forced to choose between preventing membrane biofouling or preventing membrane damage from oxidizing biocides.

Abstract: A system for dissolving solid chemical may include three reservoirs positioned in a vertically stacked arrangement. A solid chemical reservoir configured to receive solid chemical to be dissolved may be nested in a solution generator reservoir into which water is introduced to erode the solid chemical. A dissolved chemical reservoir can be positioned under the solid chemical reservoir and the solution generator reservoir. The dissolved chemical reservoir can store solution generated using the system. In some examples, a recirculation circuit is used to recirculate water introduced into the solution generator reservoir until a solution having a target concentration of the chemical being dissolved is achieved. The recirculation circuit may include a recirculation line having an outlet aimed at the bottom wall of the solid chemical reservoir.

Abstract: A system for management of solid chemistry supply can be configured to use operating attributes and sensed operating conditions associated with a process to estimate solid chemistry supply levels. The system can also be configured to control a feeder attached to a solid chemistry supply container. The control can include controlling a dose of a solid chemistry product to the container according to the estimation. The system can also be configured to communicate a message regarding an insufficient supply of the solid chemistry product.
