International Classification:
C02F 1/20, C02F 1/44, C02F 1/66, B01D 69/08, B01D 61/00
US Classification:
210638, 210151, 210137, 210 88
Abstract:
Apparatuses, systems and processes for fluid gasification and degasification are disclosed. A fluid gasification/degasification apparatus includes housing having a central axis and at least one fluid inlet and at least one fluid outlet positioned at different axial locations along the housing. A membrane unit that includes a plurality of bundled microporous hollow membrane strands is disposed within the housing and extends in parallel to the central axis of the housing. The fluid gasification/degasification apparatus further includes one or more gas addition/removal apparatuses for facilitating at least one of: a gas addition operation and a gas removal operation. An orientation of the fluid inlet(s) and fluid outlet(s) results in a substantial portion of a carrier fluid introduced to the housing traveling in parallel along exterior surfaces of the membrane unit thereby allowing for an extended interface time between the carrier fluid and micro-bubbles of a gas supplied to the membrane unit.
System And Method For Interlocking Support Blocks
US Patent:
8069630, Dec 6, 2011
Filed:
Mar 27, 2007
Appl. No.:
11/728868
Inventors:
David C. Slack - Tampa FL, US

Assignee:
Severn Trent Water Purification, Inc. - Colmar PA
International Classification:
E04C 3/00, E04C 2/04, E04B 2/00, B01D 24/00, B01D 24/12
US Classification:
525891, 52578, 525901, 525902, 525911, 525921, 525881, 52604, 210289, 210293
Abstract:
A system and method for forming a filter media support system with multiple locking mechanisms. The support system comprises two or more interlocking rows of support blocks. One or more slides and one or more guides protrude from the side walls of the blocks. Each guide is conformed to receive one slide from a neighboring block, forming a first locking joint. The side walls also comprise one or more nubs and one or more recesses. Each nub is conformed to fit within one recess of a neighboring block, forming a second locking joint. In one embodiment, the method for assembling the support system comprises aligning a slide of a first support block with a guide of a second support block. The slide of the first support block is vertically moved into the guide of the second support block. Force is applied so that the nubs are flexed within the recesses.
Snap Locking Underdrain Block
US Patent:
2005021, Oct 6, 2005
Filed:
Apr 5, 2004
Appl. No.:
10/818157
Inventors:
David Slack - Tampa FL, US

Navin Kadakia - Bridgeville PA, US
International Classification:
B01D024/46, B01D024/14
US Classification:
210275000, 210293000, 210289000
Abstract:
An underdrain block for a filter system comprises a housing that has of a top wall, a bottom wall, a first end wall, a second end wall, a first side wall, and a second side wall. The end walls and the side walls connect the top wall to the bottom wall. The bottom wall forms two lateral rows of support legs configured to straddle infrastructure of the filter system. One or more snap-locking mechanisms are located on the side walls so that adjacent underdrain blocks are interconnected by the locking mechanisms when snapped in place. In one embodiment, the first side wall comprises one or more tongue lugs and the second side wall comprises one or more groove lugs, each groove lug defines a groove for mating with the tongue lug so that adjacent housings are interconnected by the tongue-in-groove locking mechanisms when the tongue lugs are snapped into the grooves.
Underdrain Apparatus

Assignee:
Severn Trent Water Purification, Inc. - Colmar PA
International Classification:
B01D 24/24
US Classification:
210232, 210293
Abstract:
An underdrain apparatus includes one or more underdrain blocks and an anchor assembly that includes one or more support members. Each of the underdrain blocks includes a top wall, a bottom wall, a pair of opposing side walls, a pair of opposing end walls, and a center separation wall that extends between the pair of opposing end walls. The center separation wall of at least one of the underdrain blocks may have one or more apertures formed therein, the apertures configured to receive at least one of the support members. One or more of the side walls of the pair of opposing side walls of the underdrain blocks may have one or more side clips. At least one of the side clips defines an aperture for receiving a support member.

Abstract:
A system and method for forming a filter media support system with dual locking mechanisms. The support system comprises two or more interlocking rows of support blocks. One or more slides and one or more guides protrude from the side walls of the blocks. Each guide is conformed to receive one slide from a neighboring block, forming a first locking joint. The side walls also comprise one or more posts and one or more sockets. Each post is conformed to fit within one socket of a neighboring block, forming a second locking joint. In one embodiment, the method for assembling the support system comprises aligning a slide of a first support block with a guide of a second support block. The slide of the first support block is vertically moved into the guide of the second support block. Force is applied so that the posts snap-lock into the sockets.
