Abstract
Abstract A system for the environmentally-safe, unified treatment of a wastewater effluent is disclosed in which there is provided: a primary treatment component comprising at least one means for the removal of solids, a secondary treatment component comprising at least one filtration field adapted for the secondary and advanced treatment of a wastewater effluent, and means to capture and convey effluent; an advanced treatment component adapted to provide further advanced treatment of a wastewater effluent comprising at least one effluent accumulation means; at least one dosate storage and dosing means associated with each such effluent accumulation means; and at least one holding means capable of holding the dosed effluent in an anoxic condition; said advanced treatment component being adapted to accumulate, dose and hold the effluent for treatment in an anoxic condition; and a polishing component comprising at least one infiltration field to discharge effluent.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
182 words
A system for the environmentally-safe, unified treatment of a wastewater effluent, said system comprising: a primary treatment component comprising at least one means for the removal of solids from said wastewater effluent to provide a clarified effluent substantially free of solids; a secondary treatment component comprising at least one filtration field for the secondary treatment of the clarified effluent stream from the primary treatment component to provide a nitrified effluent, and means to capture and convey said nitrified effluent; a batch type advanced treatment component to provide advanced treatment of a nitrified effluent comprising: at least one effluent accumulation means; at least one dosate storage and dosing means associated with each such effluent accumulation means; and at least one holding means capable of holding a dosed nitrified effluent in an anoxic condition, wherein said advanced treatment component can accumulate, dose and hold the nitrified effluent for treatment in an anoxic condition to provide a de-nitrified effluent; and a polishing filtration component comprising at least one infiltration field to filter the de-nitrified effluent to provide a treated effluent and discharge said treated effluent.
Claim 2
Independent Claim
182 words
A system for the environmentally-safe, unified treatment of a wastewater effluent, said system comprising: a primary treatment component comprising at least one means for the removal of solids from said wastewater effluent to provide a clarified effluent substantially free of solids; a secondary treatment component comprising at least one filtration field for the secondary treatment of the clarified effluent stream from the primary treatment component to provide a nitrified effluent, and means to capture and convey said nitrified effluent; a batch type advanced treatment component to provide advanced treatment of a nitrified effluent comprising: at least one effluent accumulation means; at least one dosate storage and dosing means associated with each such effluent accumulation means; and at least one holding means capable of holding a dosed nitrified effluent in an anoxic condition, wherein said advanced treatment component can accumulate, dose and hold the nitrified effluent for treatment in an anoxic condition to provide a de-nitrified effluent; and a polishing filtration component comprising at least one infiltration field to filter the de-nitrified effluent to provide a treated effluent and discharge said treated effluent.
Claim 3
Dependent Claim
17 words
The system of claim 1, wherein the secondary treatment component comprises both a biological and physical filter.
Claim 4
Dependent Claim
17 words
The system of claim 1, wherein the advanced treatment component further comprises means to monitor the effluent.
Claim 5
Dependent Claim
20 words
The system of claim 1, wherein the advanced treatment component further comprises means to treat other impurities in the effluent.
Claim 6
Dependent Claim
37 words
The system of claim 1, wherein the primary treatment component comprises a plurality of interconnected means for the removal of solids, such that any such means may be disconnected from the system for service, regeneration or replacement.
Claim 7
Dependent Claim
34 words
The system of claim 1, wherein the secondary treatment component comprises a plurality of interconnected filter fields, such that any such filter field may be disconnected from the system for service, regeneration or replacement.
Claim 8
Dependent Claim
34 words
The system of claim 1, wherein the advanced treatment component comprises a plurality of interconnected accmulation means, such that any such accumulation means may be disconnected from the system for service, regeneration or replacement.
Claim 9
Dependent Claim
34 words

Claim 13
Dependent Claim
34 words
The system of claim 10 wherein the means for the additional advanced treatment of the nitrified effluent is intended to function sequentially with the accumulation, dosing and holding means of said advanced treatment component.
Claim 14
Dependent Claim
111 words
A process for the environmentally-safe, unified treatment of a wastewater effluent, said process comprising: primary treatment including sedimentation of a wastewater effluent to substantially remove suspended solids, providing a clarified effluent; secondary treatment including filtration of the clarified effluent through a filtration field to oxidize organic materials and provide a nitrified effluent; capture and conveyance of the nitrified effluent to a batch type advanced treatment zone wherein the nitrified effluent is accumulated and dosed with a controlled carbon source and held in an anoxic condition to provide a de-nitrified effluent; and filtration of the de-nitrified effluent through an infiltration field to provide a treated effluent and discharge of the treated effluent.
