Abstract:
A process for the treatment of wastewater is disclosed, which comprises (a) contacting the wastewater with fast settling sludge from step (c) in an anaerobic zone, obtaining a mixture of wastewater and sludge; (b) subjecting the mixture from step (a) and slow settling sludge from step (c) to an aerobic zone, obtaining a water and sludge mixture; (c) subjecting a first part of the mixture from step (b) to a sludge selection step, wherein sludge is selected based on settling velocity and a first portion containing slow settling sludge and a second portion containing fast settling sludge are collected, wherein average settling velocity of the fast settling sludge is greater than that of the slow settling sludge, and wherein the first portion is returned to step (b) and the second portion is returned to step (a); and (d) separating sludge from a second part of the mixture from step (b).

Claim (Index 25):
A system for carrying out the process according to  claim 16 , comprising:\n (a) an anaerobic tank, comprising one or more inlets for receiving wastewater and for receiving fast settling sludge originating from outlet (c 3 ) and an outlet (a 3 ) for discharging a mixture of wastewater and sludge to tank (b); (b) an aerobic tank, comprising an inlet (b 1 ) for receiving the mixture of wastewater and sludge originating from outlet (a 3 ), an outlet (b 2 ) for discharging a first part of a mixture of water and sludge to sludge selector (c), an outlet (b 3 ) for discharging a second part of the mixture of water and sludge to separator (d) and an inlet (b 4 ) for receiving a mixture of slow settling sludge originating from outlet (c 2 ); (c) a sludge selector, comprising an inlet (e 1 ) for receiving the first part of the mixture of water and sludge originating from outlet (b 2 ), an outlet (c 2 ) for discharging a first portion of slow settling sludge to tank (b) and an outlet (c 3 ) for discharging a second portion of fast settling sludge to tank (a) and means (c 4 ) for selecting sludge based on settling velocity; and (d) a separator for separating sludge from a mixture of sludge and water, comprising an inlet (d 1 ) for receiving the second part of the mixture originating from outlet (b 3 ), a first outlet (d 2 ) for discharging treated water and a second outlet (d 3 ) for discharging separated sludge, wherein outlet (a 3 ) is in fluid connection with inlet (b 1 ), outlet (b 2 ) is in fluid connection with inlet (c 1 ), outlet (b 3 ) is in fluid connection with inlet (d 1 ), outlet (c 2 ) is in fluid connection with inlet (b 4 ) and outlet (c 3 ) is in fluid connection with an inlet of unit (a).
