A continuous net placed under the slatted floor filtrate the feces from the urine. Different testing have realized in order to determine the optimum operations parameter such as the net mesh size (optimum size 800 microns), the correct location for the net under the slatted floor and its dimension (depending on the position of the equipment and production pattern). The solid phase removed using this system is of 26% of dry matter and the liquid part is of 2%. The solid part can be composted (and disposed later) and the liquid can be spread on grass or land as a fertilizer. No information on the economics of such system is not given. Such system could be considered if a lot of manure hauling has to be done on long distances. The liquids could be spread close to the storage facility and the solids of smaller volume and more concentrated per volume could be transported and used as a fertilizer further from the farm. The lower cost in transportation could compensate for the cost of such separation system.
