Wastewater concentrator method and system

A system for adjusting wastewater loading in a feed path of a biological treatment stage in a sanitary wastewater treatment plant, comprising:

• a separator configured to separate solids and liquid from the diverted wastewater, the separator including:
• (a) an inlet arranged and adapted to receive a portion of wastewater diverted from the feed path of the biological treatment stage, and (b) a first outlet configured to discharge the solids and not discharge at least a substantial portion of the liquid, the first outlet operatively connected to the feed path downstream from the diverted wastewater;
• a sensor and a flow transmitter in the treatment plant inlet for sensing the flow therein;
• and
• one or more flow controllers, configured to dynamically jointly adjust in response to signal from said sensor and said flow transmitter:
• a) a rate at which the solids are reintroduced into the feed path;
• and
• b) a rate at which the wastewater is diverted from the feed path in such a way that a quantity of wastewater flowing into the biological treatment stage per unit time downstream of the diverting is adjusted to be no more than a preset quantity.

A method for processing wastewater within a sewer main, comprising:

• diverting a portion of wastewater flowing through the sewer main;
• separating solids in the diverted wastewater from liquid therein;
• reintroducing the solids into the sewer main and not reintroducing at least a substantial portion of the liquid;
• sensing the wastewater loading in said sewer main;
• and
• dynamically jointly adjusting in response to said sensing:
• a) a rate at which the solids are reintroduced;
• and
• b) a rate at which wastewater is diverted, the dynamically jointly adjusting being carried out in such a way that a quantity of wastewater flowing through the sewer main per unit time downstream of the diverting is adjusted to be no more than a preset quantity.
