Apparatus for treating water has a container having a clarification zone, a water entry arrangement for flowing water into the clarification zone, and water exit units mounted to the container for at least partial immersion in the water in the clarification zone. Each water exit unit has a transfer channel for transferring a flow of clarified water from a layer of the water to a predetermined depth in the clarification zone and to direct the received clarified water to a water exit arrangement. A height adjustment mechanism is used for differentially adjusting the heights of the water exit units and their transfer channels relative to the container so as to compensate for any angular tilt of the container owing to the container being deployed on sloping ground.

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.
An intermodal container has a roof, floor, side walls and end walls converted for use as a water processing tank, the tank walls reinforced so that the tank can be filled with water. The tank is lines with a flexible liner. On one of the walls aligned apertures are made in the liner and the wall with an inwardly facing flange surface facing into the tank. A process wall is mounted against the flange surface with fastening bolts exposed at the outside of the tank. The process wall is bolted from outside the tank so that a margin of the liner at the aperture is pinched between the process wall and the flange surface to seal it in place. Interface components are mounted and sealed at ports in the process wall to provide inputs to, and outputs from, the tank interior both above and below the design level of water in the tank.

A system for treating water has a plurality of concatenated reverse osmosis (RO) units, each having a membrane. Water to be treated is fed to one side of the membrane at a pressure to overcome osmotic pressure across the membrane and to force permeate to the other side of the membrane. The water on the one side of the membrane retains dissolved solids to become concentrate. Concentrate from a downstream RO unit is directed to the other side of the membrane of the upstream RO unit to mix the directed concentrate from the downstream RO unit with the permeate of the upstream RO unit. The mixed concentrate and permeate from the upstream unit is then treated at the downstream RO unit.
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.

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.

An intermodal container converted to a tank for processing wastewater has a process wall detachable from a hatchway in a wall of the container. The process wall is bolted to an interior facing flange in the container wall and is installed so as to sandwich a gasket and a lip between the process wall and the flange. When the process wall is at a container end wall, first components for interface with water to be treated are sealingly fixed into one part of the process wall designed to be below the level of contained water. Second process components such as those associated with communication cabling, power cabling or piping to be run through the converted container are sealingly fixed into an upper part of the process wall above a design level of contained water to be treated.

METHOD AND APPARATUS FOR CLEANING A FILTRATION CASSETTE OF A MEMBRANE BIO-REACTOR
A method and apparatus for cleaning a membrane bioreactor having a stack of generally vertically oriented membrane filter packs mounted in a filtration chamber containing wastewater. In a first cleaning phase, air is supplied to a first discharge zone under the stack to discharge air bubbles into the wastewater at the bottom of the stack so that the air bubbles rise upwardly through passages between the filter packs to scour surfaces of the membranes bounding the passages. In a second cleaning phase, air is supplied to a second discharge zone at the bottom of the stack and surrounding it to cause air lift induced circulation of the wastewater up around the sides of the stack and downwardly through the passages between the filter packs.
