PURPOSE:To remove water from sewage and concentrate the sewage by incorporating a frother into the sewage in the storage tank of a simple flush toilet, introducing air into the sewage, and aerating the sewage to remove the air contg. steam along with bubbles. CONSTITUTION:A water removing device is set to the sewage storage tank for a simple flush toilet through a lid. The inside pipe 7 of the water removing device is slightly immersed in the sewage, and the outside pipe 6 provided with the lid 8 having an inspection hole 9 is immersed in the sewage slightly deeper than the inside pipe 7. An air diffuser 10 is provided to the tip of the inside pipe 7 for introducing air to diffuse air, and the water is evaporated in the vicinity of the diffuser by the bubbles 14 formed by the action of the frother previously incorporated in the sewage. The bubbles and air pass through the space between the outside pipe 6 and the inside pipe 7, and are removed from a bubble removing pipe 11. In this case, the air and bubbles are effectively removed by using a fan 12.
