Hi Ria: An innovative approach to effectively remove barnacles from desalination plant intakes includes sequential addition of sodium hypochlorite at a dosage of 5 to 15 mg/L for 6 to 8 hours followed by the addition of sulfuric acid at dosages of 120 to 180 mg/L for 6 to 8 hours. While the chlorine helps to kill the shellfish attached to the pipe walls, the sulfuric acid dissolves the biological glue by which they are attached to the walls and they are than collected at the intake screens by the incoming seawater.
