The phosphorous removal system would consist of a pump station which would convey the final clarifier effluent to a mixing/flocculation basin where the alum would be added to react with the soluble phosphorous to form a solid floc that would then be removed from the effluent by tertiary sand filters.
	It is proposed that a 2000-gallon alum storage tank be provided with secondary containment. The tank would be equipped with mixers and heating elements to maintain minimum temperature.
	Duel metering pumps would be provided that would feed the alum to the selected point of application.
	The addition of alum will result in additional sludge production. It is proposed to proved a sludge holding tank. This tank would be aerated and mixed using a submersible aspirating mixer. Some sludge digestion should be achieved within this tank.
	Alum dosage is influenced by pH. The plant currently has the ability to add caustic to raise pH.
	To comply with the reliability requirement for two operational clarifiers, we will refurbish the original thirty-foot clarifier. This will require the installation of a new splitter box to divide the wastewater flow between the two clarifiers, the replacement of the clarifier equipment, and the installation of a new return sludge pump.
