Abstract: A flexible entry boot provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The flexible entry boot comprises a seal member disposed within the containment region; and a securing plate disposed within the containment region and releasably mounted to the seal member. A flexibly rigid, hollow support sleeve is attached to the seal member. The hollow support sleeve has a degree of flexibility sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. A mechanism is provided for releasably attaching the hollow support sleeve to the conduit.

Abstract: A flexible entry boot assembly provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The flexible entry boot assembly comprises a seal member disposed within the containment region. The seal member has a substantially planar seal portion and an integral hollow support sleeve concentric with the seal portion and extending axially into the containment region. The support sleeve has an outer surface and an inner, conduit receiving surface, the hollow support sleeve further having a degree of flexibility relative to the seal portion sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. The flexible entry boot assembly further comprises a mechanism for rigidifying the seal portion of the seal member. A mechanism is provided for releasably attaching the hollow support sleeve to the conduit.

Abstract: A system for housing secondarily contained flexible piping comprises a flexible conduit resistant to mechanical stresses, the conduit adapted to surround the secondarily contained flexible piping. The conduit comprises a metallic core and a thermoplastic jacket. The secondarily contained flexible piping comprises an inner supply pipe, wherein the inner pipe is comprised of a first, inner layer fabricated from nylon, a second, intermediate layer comprising a nylon reinforced wrap, and a third, outer layer comprising a polyethylene material, the nylon inner material, the nylon wrap and the polyethylene outer layer being extruded simultaneously to form the inner pipe.

Abstract: A tank sump has a one-piece body comprising a hollow base member for collecting fluids leaking from a piping system, the base member having an upper portion and a lower portion, and a hollow riser section having an upper portion and a lower portion, the riser lower portion extending upwardly from the base member upper portion, the riser section having sidewalls with alternately adjacent vertically extending wall portions and outwardly extending, U-shaped grip portions. An integrally formed cover is defined on top of the riser section upper portion. The cover may be cut off from the riser section of the body. A gasket may extend between the cover outer periphery and the outwardly extending grip portion of the riser section, and a mechanism removably secures the cover to the outwardly extending grip portion with the gasket therebetween, in a substantially water resistant sealing manner. The cover may alternately be cut away from the body and discarded.

Abstract: An integrally formed flexible entry boot provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The flexible entry boot comprises a seal member disposed within the containment region and a screw securing plate mounted to the seal member. A cylindrical hollow support sleeve has a degree of flexibility sufficient to allow for the insertion of the conduit at angles less than or equal to an angle normal to the fluid containment wall while maintaining a fluid-tight environment, the hollow sleeve having a first open portion integrally attached to the seal member, the first open portion having a central throughbore in fluid communication with the cylindrical hollow support sleeve, the hollow sleeve having a second open portion opposed to, and integrally attached to the first open portion, the first open portion adapted to flexibly receive the conduit, and the second open portion adapted to releasably hold the conduit in place.

Abstract: A height adjustable water-tight sump for use in hazardous waste storage systems. The sump comprises an inspection cover, an access cover, a riser section and a base. The riser section has alternately adjacent threaded sections and grip sections in appropriate areas along the riser for height adjustment of the sump in that, at a desired height, the riser section may be cut off to conform to that desired height. To form the sump the riser section is threadably engageable with the base, the access cover is threadably engageable with the riser section, and the inspection cover is threadably engageable with the access cover.

Abstract: A permeable membrane system comprised of at least two sheets, at least one of the two sheets being a grooved permeable membrane having regularly spaced grooves on at least one surface, the grooves having a predetermined spacing factor, the grooved permeable membrane either having essentially no barrier layer or having a barrier layer on one grooved surface, the sheets being positioned in a configuration with the grooves of that one grooved surface of the grooved permeable membrane sheet forming feed channels with a surface of another sheet which covers that one grooved surface, the grooves being about 0.5 to about 100 mils wide and deep and the feed channels being used to deliver the feed stream to the membrane surface. Preferably, both sheets are permeable membranes. The grooves in the sheets are preferably about 5 to about 35 mils wide and deep for reverse osmosis, about 0.5 to about 20 mils wide and deep for gas separation, and about 15 to about 75 mils wide and deep for ultrafiltration.
