REAR-ORIENTED DEBRIS CANISTER

Thu, 06 Apr 2017 08:00:00 EDT

Swimming pool cleaners are detailed with filtration components attached at the rears of their bodies. At least some of the components may be external to a body, rather than within it, so as to provide greater surface area for filtered water to exit. They also may allow users to view the quantity of debris trapped in the filter without having to dissemble the cleaner. By contrast with many existing external filter bags, moreover, the components need not protrude materially above (or below) the heights of the bodies, hence avoiding creation of hydraulic drag as the cleaners move within pools, spas, or other liquid-containing vessels.

METHOD OF OPERATING MEMBRANE FILTER

Thu, 06 Apr 2017 08:00:00 EDT

A method of operating an immersed microporous membrane module includes a step of monitoring membrane performance to sense the onset of sludging in the module. Differences in permeability between permeation in backwashes, or trends in permeability during backwashing and permeability during permeation, or both, are monitored. Solid deposits formed during the onset of sludging may be removed with an in situ de-sludging process. For example, the deposits may be removed by stopping permeation while aerating the module, optionally at an increased rate. At other times, the module is optionally aerated while permeate is withdrawn at an aeration rate correlated to flux. The method may be used in particular with a membrane module having parallel textured flat sheet membranes suspended between a pair of vertically oriented headers. An aerator may be made from an open bottomed channel having an array of holes rising and concentrated towards the center of the channel.
