27、olved metals. The system can be a stand-alone system, or it can be a pretreatment system for other systems such as air stripping, advanced oxidation, activated carbon, etc. Ancillary P/C/F equipment which may be required for pre-treatment or post-treatment of the water is also described and includes
28、 an equalization unit, an oxidation/reduction unit, a clarification unit, a post-pH adjustment unit, and an effluent holding unit. The precipitation, coagulation, and flocculation units may be supplied by the Contractor SECTION 02 51 13 Page 6Provided by IHSNot for ResaleNo reproduction or networkin
29、g permitted without license from IHS-,-,-as individual pieces of equipment or as a single, integral unit. Typically, if a single unit is supplied, it will incorporate the coagulation, flocculation, and precipitation equipment within a clarification unit. Alternately, a unit may be supplied which per
30、forms two of the processes, e.g., precipitation and coagulation within one unit.This paragraph should be edited to identify only the necessary equipment to suit conditions at the project site. The design team should review treatment objectives, water characterization data, and results of previously
31、conducted treatability testing and other predesign information to determine the equipment required.*The Precipitation/Coagulation/Flocculation (P/C/F) system shall be a fully integrated water treatment plant which shall remove dissolved heavy metals and solids from groundwater and landfill leachate
