Abstract: An automated chemical storage and chemical feed system for a use station to chemically treat and monitor a process at a use station where the process is being run, including one or more base chemical supply tanks at the use station storing chemicals and intermittently or continuously feeding the chemicals to the process. A level sensor is provided in each base tank to determine the chemical level and to deliver a signal to a control and processing unit. Sensors may be provided on the process for providing chemical condition information to the control and processing unit.

Abstract: A portable liquid container has a four-sided shell enclosed by a bottom wall and a top wall. The bottom wall is formed by four triangular portions sloping downwardly to a delivery opening. The top wall has an upwardly sloping configuration with an enlarged opening in the middle thereof. The opening is normally covered by a lid. Two lifting channels and a delivery pipe and valve are located on the underside of the bottom wall. Four legs attached to the bottom wall support the container at a height sufficient to clear the delivery pipe and lifting channels. Leg positioners are located at the upper corners of the container and are arranged to receive the legs of a second like container stacked on top of a first container.
