Abstract
Abstract The invention relates to apparatus 1 for treating a fluid such as sewage in situ, comprising a housing 2 which is transportable, there being one or more modules 2a, 2b, 2c in the housing for carrying out one or a sequence of treatment operations on the sewage. There is an inlet 3 whereby the apparatus is connectible with a source of sewage to be treated and an outlet 4 from the apparatus for passage therefrom of sewage treated therein. The apparatus may be mounted on or incorporated in a vehicle for movement between different sites.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
171 words
Apparatus for treating a fluid, comprising a plurality of self-contained, separately housed, transportable modules each carried on a separate mobile carrier, including at least one treatment module for carrying out a particular treatment of the fluid, a control module, and a systems module, the control module having a first inlet for receiving raw fluid to be treated and a first outlet for discharging the treated fluid, a second inlet and a second outlet respectively connectible to an outlet and an inlet of said treatment module for exchanging the fluid from the control module to the treatment module and back to the control module, and a third inlet and a third outlet respectively connectible to an outlet and an inlet of said systems module for exchanging the fluid between the control module and said systems module, said systems module including pump means for pumping the fluid through all of the interconnected modules, whereby the modules are individually transportable to a site for assembly and interconnection to form an integral fluid treatment system.
Claim 2
Dependent Claim
171 words
Apparatus for treating a fluid, comprising a plurality of self-contained, separately housed, transportable modules each carried on a separate mobile carrier, including at least one treatment module for carrying out a particular treatment of the fluid, a control module, and a systems module, the control module having a first inlet for receiving raw fluid to be treated and a first outlet for discharging the treated fluid, a second inlet and a second outlet respectively connectible to an outlet and an inlet of said treatment module for exchanging the fluid from the control module to the treatment module and back to the control module, and a third inlet and a third outlet respectively connectible to an outlet and an inlet of said systems module for exchanging the fluid between the control module and said systems module, said systems module including pump means for pumping the fluid through all of the interconnected modules, whereby the modules are individually transportable to a site for assembly and interconnection to form an integral fluid treatment system.
Claim 3
Dependent Claim
30 words
Apparatus as defined in claim 1, including a plurality of said treatment modules on separate module carriers and which are connectible to corresponding inlets and outlets of said control module.
Claim 4
Dependent Claim
27 words
