ABSTRACT:
Disclosed is a wet process recovery system for solid waste. The waste is fed into a hydrokinetic separation step wherein it is immersed in a body of water which is subjected to rising and lateral flows. These flows establish a synthetic gravitational environment to effect separation of solids above and below a predetermined density greater than the density of water. The solids having the higher densities are collected by gravity and transported from the water for recycling. A modified hammermill is connected to the body of water and the rising and lateral fluid flows cooperate to carry waste into a cutting and ejecting mechanism which both shears friable waste and dynamically ejects non-friable waste back into the liquid. The output of the hammermill is a slurry of comminuted waste in the liquid. This is pumped to a centrifuge separator where solid waste is separated from liquid and the liquid recirculated to the body of water to create the flows in that body. The solid waste output is in a deliquified form suitable for use in a waste to energy incineration process.
