Abstract:
An apparatus for controlling the injection of chemicals in a waste water treatment facility, comprising:(a) means for monitoring one or more contamination sites and generating a contamination signal in response to the type of contamination, wherein the monitoring means monitors the type of contamination at the contamination site, wherein the means for monitoring is a laundry washer controller generating the contamination signal based at least in part on user entered information on the type of objects being laundered; (b) an equalization tank for collecting the waste water from the one or more contamination sites; (c) a flow meter for monitoring the volume of waste water discharged from the equalization tank and for generating a flow volume signal; (d) a metering device for portioning a chemical into the waste water, the metering device operating in response to a control signal; and (e) a controller operatively connected to the monitoring means and the flow meter, the controller receiving the contamination signal and the flow volume signal and generating a control signal for the metering device in response, whereby the amount of chemical for treating the waste water is optimized.
