METHOD TO SELF-CLEAN AN IFS USING SUPERNATANT FROM ANOTHER CLARIFICATION TANK

摘要

A method to self-clean an influent feed system (IFS) trough of a wastewater treatment facility with flushing by a supernatant includes: providing two or more clarification tank systems, each clarification tank system fluidly coupled via one or more pipes to at least one of another of the clarification tank systems; filling one of the clarification tank systems with an influent so that a fluid level in the clarification tank rises above another fluid level in another clarification tank; settling the influent in the clarification tank so that a layer of supernatant forms in an upper portion of the clarification tank; and flowing a portion of the supernatant from the clarification tank to one or more IFS troughs of one or more IFS in another clarification tank to self-clean the one or more IFS troughs of one or more IFS in the another clarification tank.

1. A method to self-clean an influent feed system (IFS) trough of a wastewater treatment facility by flushing with a supernatant comprising:
providing two or more clarification tank systems, each clarification system having disposed within a clarification tank one or more IFS, each clarification tank system fluidly coupled via one or more pipes to at least one of another of said clarification tank systems; filling one of said clarification tank systems with an influent so that a fluid level in said clarification tank rises above another fluid level in another clarification tank; settling said influent in said clarification tank to form a layer of supernatant in an upper portion of said clarification tank; and flowing a portion of said supernatant from said clarification tank to one or more IFS troughs of one or more IFS in another clarification tank to self-clean said one or more IFS troughs of one or more IFS in said another clarification tank.
