A sewerage treatment system comprising water closet means, bathing facility means, first and second filtrate compartments, means including filtering media for selectively directing at least a portion of the liquid component of the effluent flushed from said water closet means into either of said first or second filtrate compartments, means for selectively directing at least a portion of the effluent discharge from said bathing facility means into either of said first or second filtrate compartments, means for selectively recirculating the liquid in either of said first or second filtrate compartments to said water closet means for flushing same, means for operating the system in a first mode of operation wherein at least a portion of the liquid component of the effluent flushed from said water closet means is directed into one of said filtrate compartments, the liquid in said one filtrate compartment is selectively recirculated to said water closet means, and at least a portion of the effluent discharged from said bathing facility means is directed into the other one of said filtrate compartments, and means for alternately operating the system in a second mode of operation wherein at least a portion of the liquid component of the effluent flushed from said water closet means is directed into the other filtrate compartment, the liquid in said other filtrate compartment is selectively recirculated to said water closet means, and at least a portion of the effluent discharged from said bathing facility means is directed into said one filtrate compartment.
Claim 2
Dependent Claim
248 words
A sewerage treatment system comprising water closet means, bathing facility means, first and second filtrate compartments, means including filtering media for selectively directing at least a portion of the liquid component of the effluent flushed from said water closet means into either of said first or second filtrate compartments, means for selectively directing at least a portion of the effluent discharge from said bathing facility means into either of said first or second filtrate compartments, means for selectively recirculating the liquid in either of said first or second filtrate compartments to said water closet means for flushing same, means for operating the system in a first mode of operation wherein at least a portion of the liquid component of the effluent flushed from said water closet means is directed into one of said filtrate compartments, the liquid in said one filtrate compartment is selectively recirculated to said water closet means, and at least a portion of the effluent discharged from said bathing facility means is directed into the other one of said filtrate compartments, and means for alternately operating the system in a second mode of operation wherein at least a portion of the liquid component of the effluent flushed from said water closet means is directed into the other filtrate compartment, the liquid in said other filtrate compartment is selectively recirculated to said water closet means, and at least a portion of the effluent discharged from said bathing facility means is directed into said one filtrate compartment.
Claim 3
Dependent Claim
20 words
A sewerage treatment system according to claim 1, wherein said water closet means comprises a plurality of toilets and/or urinals.
Claim 4
Dependent Claim
21 words
A sewerage treatment system according to claim 1, wherein said bathing facility means comprises a plurality of sinks and/or liquid drains.
Claim 5
Dependent Claim

Dependent Claim
53 words
A sewerage treatment system according to claim 5, further comprising second means for sensing when the fluid level in said one filtrate compartment during the first mode of operation substantially reaches the top thereof and for actuating said introducing means until the liquid level in said other filtrate compartment reaches said selected level.
Claim 8
Dependent Claim
29 words
A sewerage treatment system according to claim 1, further comprising a source of odor and/or color control additives and means for selectively introducing a portion thereof into the system.
