Abstract:
A sludge collector arrangement has a settling tank having side walls sloping downwardly and inwardly towards the base of the tank to from a V-base. A sludge collection unit located in the bottom of the tank has one funnel part facing in one direction and another funnel part facing in the other direction so that when the unit is driven backwards and forwards in the V-base, sludge is driven into one or other of the funnel parts. The funnel parts communicate with a central chamber and a port in a wall of the chamber allows sludge to be drawn by a suction pump from the chamber for subsequent disposal.
Abstract:
A tank for processing wastewater has reinforced side and end walls, a top wall and a floor. A flexible liner is mounted inside the tank. Regions of the top wall have reinforcing elements fixed thereto. The reinforcing elements have fixture elements integral therewith for suspending and supporting items in the interior of the tank.
Abstract:
Apparatus for treating water has a generally rectangular container for containing the water, the container having a clarification zone and a settling zone. An entry conduit extends along the container and receives water from a water inlet. Water outlet ports are distributed along the length of the conduit for directing water from the conduit into the settling zone. A water exit trough spaced across the container from the entry conduit and extending along the container receives clarified water flowing from the settling zone through the clarification zone. The top of the settling zone is open to allow access down through the settling zone to a sludge collection zone in the bottom of the container.
Abstract:
A membrane filtration apparatus located in a filtration chamber has a number of membranes and an associated support structure having a plurality of input passages and output passages. Wastewater is delivered to the input passages at one side of the membranes and the output passages receive cleaned water at the other side of the membranes after it has passed through a membrane. Each of the input passages is open at top and bottom to the filtration chamber interior, but substantially closed laterally. In a method and apparatus for cleaning the filtration apparatus, gas bubbles are discharged into the wastewater below a first subset of the input passages to cause airlift induced circulation of the wastewater up through the first subset, the flow being directed across and down through a second subset of the input passages.
Abstract:
A water treatment tank is constructed from several adjoining intermodal containers (ICs). The adjoining ICs are angularly disposed relative to each other so as to surround a tank area. Each IC has a reinforced sidewall defining a tank wall or tank wall part. A bracing structure is attached to ICs end walls at each junction between adjoining ICs. The tank having a liner supported at the sidewalls and covering the ground at the tank area.
Abstract:
An intermodal container having a roof, a floor, side walls and end walls is converted for use as a tank for processing water with the roof, floor, side walls and first end wall forming a roof, floor, side walls and one end wall of a tank. The tank has an opposing end wall fixed to the container side walls, all of the tank walls being reinforced to enable the tank to hold water. A flexible liner tub for containing water to be processed is supported by the floor and mounted against the tank walls and has a margin at a top edge. A liner cap mounted to the roof has a margin at its edge with the liner tub and the liner cap overlapping and sealed to one another at their margins.

Abstract:
A building structure has a plurality of intermodal containers (ICs) attached together and substantially surrounding a central space. The ICs support roof elements, the roof elements together forming part of a roof for the building structure. Some of the ICs and the central space house functional equipment which is connected together at a deployment site to make a system capability. Some of the ICs walls together define an outer perimeter of the building structure while other IC walls facing into the central space have walls at least partially removed to allow access to the interior of the ICs from the central space.
Abstract:
A reinforced intermodal container has a corrugated steel wall with an outer side and an inner side. In a length direction the corrugations have alternating inboard and outboard flat panels with adjacent panels linked by web portions. A strengthening structure is welded to the container wall which provides flanges extending generally perpendicularly to the general plane of the wall. The flanges extend between plates welded to the inside faces of the outboard panels and flat strengthening plates welded to the inside faces of the inboard panels. The strengthening structure does not alter the outside width of the container in comparison with the outside width of the unreinforced container. The strengthening structure reduces the inside volume of the container by only a small amount compared with the volume of the unreinforced container.
