Abstract:
1. A method for treating an agricultural-water canal to decompose organic debris in said agricultural-water canal using a device having a conduit, an air blower adapted to form an air stream and discharge said air stream to said conduit, a feed hopper open to said conduit at a feed point downstream of said air blower and adapted to feed calcium hypochlorite particles to said gaseous stream so as to form a calcium hypochlorite-laden air stream, and a port open to said conduit downstream of said feed point, wherein said conduit is adapted to channel said calcium hypochlorite-laden air stream to said port, and wherein said port is adapted to direct and propel said calcium hypochlorite-laden air stream to the surface of water in said agricultural-water canal, said method comprising the steps of: forming an air stream using said air blower; discharging said air stream to said conduit; feeding calcium hypochlorite particles having a particle size of less than 1 mm from said feed hopper to said air stream at said feed point to form a calcium hypochlorite-laden air stream in said conduit whereby said conduit channels said calcium hypochlorite-laden air stream to said port; embedding said calcium hypochlorite particles in organic debris in water in said agricultural-water canal by directing and propelling said calcium hypochlorite-laden air stream through said port to the surface of water in said agricultural-water canal at a linear velocity of from 40 to 180 miles per hour.
