PURPOSE: A membrane bioreactor-based feed water treating system and a moving bed bioreactor-based feed water treating system are provided to eliminate total suspended materials from feed water based on a hydrodynamic separator. CONSTITUTION: A membrane bioreactor-based feed water treating system includes a feed water introducing part, a suspended material eliminating module, a pre-treating module(108), an aerating part(114), a membrane module, and a hydrodynamic separator(302). The hydrodynamic separator receives feed water before the membrane module. Total suspended materials are eliminated from the feed water by the hydrodynamic separator before the membrane module receives the feed water. 90% or more of total suspended materials are continuously eliminated from the feed water.
