Immediately stop the chemical cleaning operation if any of the
associated cleaning equipment appears to be malfunctioning.
Never mix sodium hypochlorite with oxalic acid or citric acid. Such
mixture generates toxic chlorine gas.
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.
To avoid scattering of chemical solution, turn off the air scour
during a chemical cleaning.
