    摘要： A filter is disclosed. The filter includes a vessel having at least one inlet and at least one outlet, a media bed including a plurality of media layers, an uppermost media layer of the media bed including substantially uniform and spherical glass micromedia, the plurality of media layers increasing in density from the uppermost media layer to a lowermost media layer and an air distributor configured to direct a volume of air through the plurality of media layers. A system for treating water is also disclosed. The system includes a source of water to be treated, a filter vessel as described herein, and a treated water outlet fluidically connected to a filter vessel outlet. A method of retrofitting a filter vessel as described herein is also disclosed. The method includes removing the uppermost media layer from the media bed and installing a media comprising substantially uniform and spherical glass bead micromedia into the media bed as the uppermost media layer. A method of facilitating water treatment is also disclosed. The method includes providing a filter vessel as described herein and instructing a user to connect an inlet of the filter vessel to a source of water to be treated.

    摘要： A method of manufacturing a tube sheet by forming a plurality of separate thin tube sheet segments; forming multiple holes in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube; aligning all of the plurality of tube sheet segments so that the hole pattern of each sheet aligns with the hole pattern in all other sheets of the plurality of tube sheet segments; and securing all of the tube sheet segments together to form a unitary tube sheet. A tube sheet construction that includes a plurality of separate thin tube sheet segments, multiple holes being provided in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube, all of the tube sheet segments being aligning so that the hole pattern of each sheet aligns, and fasteners for securing all of the tube sheet segments together. A media layer is provided between adjacent sheet segments.

    摘要： A multi-layer media bed filter with an increasing density of media from the finest media on the top to the coarsest media on the bottom is backwashed using air without significantly disrupting stratification of the media layers. When the air is stopped, the contaminants in the liquid above the finest media that were removed by the airflow are flushed away either with liquid injected above the media or by a liquid flow through the media that does not remove the finest media. The amount of contaminants that remain in the finest media with the stratification-maintaining air backwash is significantly less than when using liquid backwash alone, whether the liquid backwash uses a flow rate sufficient to suspend the micromedia or below a suspending flow rate.

    摘要： A screening apparatus that includes a strainer element used for the purpose of retaining particulate while permitting the passage of a liquid through the strainer element, a support structure for the strainer element to enable rotation of the strainer element between opposed 180 degree positions, and a control member coupled with the strainer element for controlling the rotation of the strainer element. The strainer element, in both opposed positions thereof impedes any particulate while permitting the passage of a liquid. The control member is constructed so that, in a first state thereof, the rotation of the strainer element is periodically controlled to rotate the strainer element between said opposed 180 degree positions, and in a second state thereof, inhibits rotation of the strainer element.
