A water closet system comprising a lavatory which is connected to a collection tank or mouldering chamber (2) over a discharge piping (3), and a liquid separator (4) interconnected in said discharge piping (3) adjacent and above the tank or chamber (2). The liquid separator (4) comprises an inlet pipe (8) having a widened bottom portion (13), an outlet pipe (9) preferably having a widened top portion (14) and a liquid container which sealingly encloses at least the end portions (13, 14) of said inlet and outlet pipes (8, 9). The diameter (D2) of the top end (14) of the outlet pipe (9) is equal to of larger than the diameter (D1) of the non-widened portion of the inlet pipe (8), and the said diameter (D3) of the bottom end (13) of the inlet pipe (8) is larger than said diameter (D2) of the top portion (14) of the outlet pipe (9). The discharge piping (3) may be connected peripherally to the inlet pipe (8) of the liquid separator, and the inlet pipe (8) may have several wires provided spaced round the periphery thereof and extending down towards the center of the outlet pipe (9) for guiding solid and semi-solid material received from the inlet pipe (8) to the center of the outlet pipe (9).
A water closet system comprising a lavatory, a collection tank or a mouldering chamber and a discharge pipe between said lavatory and tank or chamber, characterized in that said discharge pipe is sized in relation to the amount of liquid normally flowed therethrough so that said amount of liquid normally flowed therethrough is small in relation to the total capacity of said pipe whereby said normal amount of liquid flow through said pipe will tend to follow the inner wall of said pipe, a liquid separator means interconnected in said discharge pipe extending between the lavatory and collection tank or mouldering chamber and adapted to separate any liquid from the combined material received from the lavatory and comprising an inlet pipe provided below the lavatory and connected to the discharge pipe and an outlet pipe connected to said tank or mouldering chamber, the lower edge of said inlet pipe being widened, the upper edge of said outlet pipe being of at least the same cross section area as the non-widened portion of the inlet pipe, and the widened edge of said inlet pipe being of at least the same cross section area as said upper edge of the outlet pipe.
