Waste Management System for the Habitant Module for CEEF 972519

A waste management system for an animal breeding/habitant module in CEEF is proposed. The waste management system consists of two subsystems, the urine treatment subsystem and the feces and daily waste treatment subsystem. Wet oxidation processes and a drying toilet process are used in those subsystems.
The urine and the feces excreted from human beings and animals in the module are separately treated in order to collect NaCl from the urine.
The urine is stored in the tank until the volume reaches a fixed level, and is sent to a wet oxidation process in the urine treatment subsystem. The liquid oxidized in the process is sent to a salinity recovery process to recover NaCl, and the produced gas is sent to a gas adjustment process. The salinity recovery process and the gas adjustment process are in another process.
The feces are treated in a wet oxidation process in the feces and daily waste treatment subsystem, and the waste oxidized in the process is moreover treated in the catalytic wet oxidation process of the plant cultivation module in order to decompose organic components completely.
Processes and major specifications of the waste management system are described.
