assume N is 0.58 mg/L

(c) Phoslock@ is a modified clay that is often added to lakes and rivers to reduce the levels of P. Phoslock reacts by forming a complex with P in the water which then settles to the lake bottom. The farmers would like to keep the Redfield ratio (i.e., N/P ratio) at a value of 8 . The concentration of Phoslock B added to the lake is directly proportional to the P settling velocity: [PhoslockB] in mg/L=2.163vs where vs is the settling velocity in m/ day. Determine the necessary settling velocity (in m/day) and Phoslock@ concentration (in mg/L ) that needs to be added to meet the desired Redfield ratio value. Assume the N
