Basic General Wastewater Study Guide

A clarifier is a circular or rectangular tank used to remove floatable and settleable solids in wastewater. Disinfection is a process used to destroy most pathogens to a safe level in the effluent. Disinfection does not destroy all microorganisms. Grit is the fine, abrasive particles removed from wastewater, such as sand and eggshells.

SBR PROCESS FOR WASTEWATER TREATMENT

eliminate the need for a separate clarifier. •The treatment cycle can be adjusted to undergo aerobic, anaerobic, and anoxic conditions in order to achieve biological nutrient removal, including nitrification, denitrification, and some phosphorus removal. •Biochemical oxygen demand (BOD) levels of less than 5 mg/L can be achieved consistently.
