Leaf Filters Provide Clarification Essential for Efficient

Clarifying filters for the Merrill-Crowe process are typically sized to run 0.75 to 0.8 gallons per minute (gpm) per square foot. "They sluice at half the flow rate," Hill says. "For example, if a plant is to run 1,000 gallons per minute, it would require 1,250 square feet of filter area and the system would sluice at 500 gpm, at pressures between 55 and 60 psi," said Hill.
