Abstract
A method of and apparatus for continuously removing dispersed particles which can be flocculated from a liquid containing said particles, such as wastewaters, wherein flocculation of said particles is caused to take place in a turbulent pipe flow by the injection and rapid mixing of a coagulant and/or coagulant aid in said turbulent pipe flow which simultaneously flocculates said particles and transports the mixture of flocculated particles and liquid into a settling tank for clarification. A controlled quantity of dispersed floc from said settling tank is continuously recirculated into said pipe flow at a station where mixing of the coagulant and/or coagulant aid is achieved, so as to reduce the length of said pipe to a desired size and the flow rate of said injected coagulant and/or coagulant aid.
