Immediately stop the chemical cleaning operation if any of the associated
cleaning equipment appears to be malfunctioning.
Do not inject any chemical into the membrane directly from the chemical
pump discharge. Excessive membrane element internal pressure will
damage the element. Be sure to inject chemicals at a pressure less than 10
kPa (100 mbar).
Before starting injecting chemical to elements, confirm that the membrane
tank liquid level is more than 500 mm above the top of the module.
Store chemicals in a dark, cold place free from direct sunlight.
Use chemical storage tanks constructed of chemically compatible materials
to prevent corrosion.
Never mix sodium hypochlorite with heavy metals or acids. The resulting
chemical reaction will generate toxic chlorine gas.
To avoid scattering of chemical solution turn off the air scour during a chemical
cleaning.
