Claim 10:
11. A system for measuring suspended solids in wastewater, comprising:
at least one optical sensor;
at least one length of tubing;
at least one pump;
a memory device that stores instructions executable by the processor to:
introduce an aqueous sample into a measurement device comprising at least one length of tubing,
pump, using the at least one pump, the aqueous sample through the at least one length of tubing;
measure, using the at least one optical sensor, a quantity of suspended solids in the aqueous sample, wherein the at least one optical sensor is coupled to the length of tubing in a position to measure the quantity of suspended solids while the aqueous sample is located in the at least one length of tubing; and
inject, using another pump, a defoamer into the aqueous sample before the pumping, wherein an amount of the defoamer is based upon the measuring.
