Abstract: A system and method for backwashing a sand filter in a wastewater treatment system. In one aspect, the invention can be a system for backwashing a sand filter comprising: a sand filter configured to remove solids from an untreated wastewater; a container storing chlorine fluidly coupled to the sand filter by a chlorine supply manifold; a flow control mechanism positioned on the chlorine supply manifold between the container and the sand filter, the flow control mechanism alterable between a first position whereby chlorine cannot flow from the container to the sand filter and a second position whereby chlorine flows from the container to the sand filter, the flow control mechanism being biased into the first position; and a processor operably coupled to the flow control mechanism and configured to automatically actuate the flow control mechanism into the second position upon detecting that the sand filter is being backwashed.

Abstract: A system for combusting volatile vapors includes a carburetor having intake valves for receiving base fuel from a fuel source, ambient combustion air, and volatile vapors from a vapor source. A plurality of sensors measure and generate sensor data based on a respective plurality of physical properties associated with the carburetor and associate combustion engine operation. One or more programmable controllers receive the sensor data and control the intake valves to regulate respective ratios of the fuel, air, volatile vapors drawn through the carburetor based on the received sensor data. To increase the burn of volatile vapors, an engine loading system automatically operated by the controller(s) applies an automatically adjustable braking load on the engine. The load level applied is based on the sensor data and commensurate with maintaining stable engine running conditions. The loading system decreases time necessary to remediate a site.
