    Abstract: Systems for leaching liquid waste, particularly waste water. More particularly, a cylindrical conduit or pipe for use in leaching systems. Even more particularly, a cylindrical conduit which has apertures/skimmer tabs created either during the manufacture/forming/extrusion of the conduit or by punching after the forming of the conduit. Most particularly, is an apparatus and method for perforating corrugated plastic pipe or smooth walled plastic pipe while the pipe is in the process of extrusion. Further and even most particularly, an actuatable perforator/skimmer tab former which may be timely acutuated to cause the perforation of the wall of pipe wherein the plastic of the portion being perforated is semi-molten as, for example during the forming of the pipe or caused to be made semi-molten after formation of the pipe such as, for example, by heating of the acuatable perforator/skimmer former thereby causing the plastic to be rolled rather than cut creating thereby a perforation and skimmer tab of predetermined and selected geometry and dimension.

    Abstract: A filter assembly comprises a plastics housing and a filter element held in the housing. The housing can be sterilized by subjecting the interior of the housing to steam under pressure while the exterior of the housing is at atmospheric pressure. The filter element comprises a water wettable filter medium. The ends of the filter medium are embedded in first and second plastics end caps. The first and second end caps form respective water-wettable joints with the filter medium and the characteristics of the filter medium are not materially changed.

    Abstract: A submerged sensor head is protected from fouling by marine organisms by positioning the sensor head in a submerged hollow enclosure. Openings are formed in the hollow enclosure to admit water but filters are positioned in the openings so that only filtered water may enter the enclosure. The filters remove biologically active marine organisms from the water and have sufficient surface area to enable free flow of water into the hollow enclosure.

    Abstract: Systems for leaching liquid waste, particularly waste water. More particularly a cylindrical conduit or pipe for use in leaching systems. The pipe further has axially directed cuts or apertures in conduit/pipe valleys, has ridges, channels and grooves over which may be laid either single or multiple layers of fabric. The corrugated pipe may have slots or slits or V-grooves in and on the various portions of the pipe such as the outer-facing surface of the ridges, the end portion of the ridges, the side wall of the groove or through the bottom portion of the groove, i.e., the valleys. The cylindrical conduit disperses moisture away from the conduit through capillary action, wicking into a surrounding material. A perforated cylindrical conduit is one method permitting wicking. The surrounding material provides capillary action to transmit moisture away from the cylinder or conduit. These surrounding materials include sand, gravel, plastic fibers, wood products, slag, and ash. A fabric or other material may surround the cylindrical conduit. For septic systems, this includes any gravel-less systems such as the SB2, Environ-Septic® and Geo-Flow® systems. Other applications of this invention include treatment of oil-contaminated water and chemically contaminated water, in addition to septic tank effluent.

    Abstract: An arrangement and method of retrofitting a filter using a disposable media to use a permanent media belt passed through a filter tank, in which movable carts are positioned at the entrance and discharge ends of the filter tank, and a roll of permanent filter media belt segment is unwound and passed through the filter tank and rewound into a roll on the other cart at the discharge end of the filter tank with the permanent filter media belt segment being cleaned and dried prior to being rewound. Upon complete rewinding of the segment, the movable carts are switched in their positions and the permanent filter media belt segment again unwound to be again passed through the filter tank with the process repeated. A second removable cart can also be positioned at the entrance side of the filter tank with the leading end connected to the trailing end of the previous belt segment automatically to be carried through the filter tank to ensure uninterrupted filter operation by successive feed of the two belt segments.
