Abstract
An in-situ foam generation apparatus includes a dissolution chamber that houses a polymer stick cavity or canister, a mixing chamber that houses a static mixer, and a foaming chamber that houses a mechanical agitator in fluid communication with a compressed air inlet. The chambers are in fluid communication with one another by way of a respective chamber inlet and outlet, with the mixing chamber being located between the dissolution and foaming chambers. A pressure regulator can be used to control the incoming aqueous solution pressure to the dissolution chamber. A nozzle exhaust is in fluid communication with the outlet of the foaming chamber. One or more polymer sticks that include one or more cleaning agent can be loaded into the cavity or canister of the dissolution chamber. An end consistency of the polymer stick can be in a range of partially solidified to fully solidified.
