Abstract
The invention relates to a liquid clarifier useful for removing solids suspended in a wastewater stream. Settled biological solids are taken from the clarifier and combined in a mixing chamber with a wastewater stream. The combined liquid is provided to a settling region of the clarifier, and suspended solids settle in a biological solids collection region, from which the solids are taken. Clarified liquid can be withdrawn or permitted to overflow from an outlet region in the settling region of the clarifier. The clarifier can enhance the degree of solids removal from wastewater streams having relatively low total suspended solids values, such as outlet streams from fixed film-type digesters. The clarifier is suitable for use in combination with other components of wastewater treatment systems, and can be included as a module in many kinds of wastewater treatment systems.
