Abstract: A method to perform autodiversion of a sand management system includes determining a first weight of a first vessel. In response to a determination that the first weight is above a first weight threshold, the method also includes actuating a first set of valves to flow the fluid from the first vessel to a second vessel of the sand management system. The method further includes flushing the first vessel.

Abstract: Control zone devices that integrate a valve, filter, and pressure regulator within a single device are provided. Specifically, the control zone devices include a main body having a base portion with an inlet passage and an outlet passage attachable to a conduit and a body portion extending from the base portion having an interior for receiving a filter. The control zone devices further include a valve body including a solenoid bowl for attaching a solenoid and an interface cap for removably coupling the valve body to the main body of the control zone device and forming an interface between the valve body and the main body to operate the valve. The control zone devices also include a pressure regulator. In some configurations, the pressure regulator is positioned in a vent flow path of the valve body downstream of the solenoid for regulating pressure at the valve.

Abstract: Citric acid is purified to remove metal ions through a two-step filtration process. A first filter is used to perform a first filtration, then a second filter is used to perform a second filtration on citric acid solution that has been subject to the first filtration. The first and second filters can include the same filter membrane material. The filter used as the first filter can be a relatively dirtier, more loaded filter compared to the filter used as the second filter. The first filtration can be performed over four hours of recirculating the citric acid solution through the first filter, and the second filtration can be performed over approximately two and one half hours of recirculating the citric acid solution through the second filter. Such a purification process can remove calcium and magnesium ions to render citric acid suitable as a cleaning solution in semiconductor processing.

Abstract: A fluid filtration system comprising a cross-flow filter is arranged to permit a first pump to recirculate part of the retentate of the filter to the inlet of the cross-flow filter and a second pump to return part of the permeate to the inlet of the cross-flow filter. A third pump is configured supply source fluid to the inlet of the filter. The flow path between the second pump and the cross-flow filter inlet may include an adsorption filter that may selectively remove contaminants, toxins, or pathogens in the permeate. A controller may control the first, second and third pumps to provide predetermined flow ratios among the fluid flow paths of the system in order to achieve a desired filtration level. This system may be applicable to the removal of harmful substances from blood, by first separating the plasma from the blood and then removing harmful substances from the plasma.
