Abstract
A method comprises the steps of receiving a wastewater containing solid particles in suspension, agitating the wastewater for a specified agitation period under specified agitation conditions sufficient to enable auto-flocculation of at least a portion of the solid particles into flocs to provide an agitated wastewater, allowing the agitated wastewater to settle for a specified sedimentation period to allow at least a portion of the flocs to settle, and separating at least a portion of the settled flocs from the agitated wastewater to provide a clarified wastewater effluent.
Claims24
A method for treatment of wastewater, comprising the steps of:
- receiving a wastewater containing solid particles in suspension;
- agitating the wastewater for a specified agitation period under specified agitation conditions sufficient to enable auto-flocculation of at least a portion of the solid particles into flocs to provide an agitated wastewater;
- allowing the agitated wastewater to settle for a specified sedimentation period to allow at least a portion of the flocs to settle;
- and
- separating at least a portion of the settled flocs from the agitated wastewater to provide a clarified wastewater effluent.
A system for treatment of wastewater, the system comprising:
- a mixing vessel configured to receive a wastewater containing solid particles in suspension and to agitate the wastewater for a specified agitation period under specified agitation conditions sufficient to enable auto-flocculation of at least a portion of the solid particles into flocs to provide an agitated wastewater;
- a settling vessel configured to allow the agitated wastewater to settle for a specified sedimentation period to allow at least a portion of the flocs to settle to a bottom of the settling vessel;
- and
- a separating device or structure configured to separate at least a portion of the settled flocs from the agitated wastewater to provide a clarified wastewater effluent.
