If any abnormality is found in the equipment during chemical

cleaning, immediately stop operation and check it.

If chemical is injected forcibly directly with the chemical feed pump

or by any other means, the internal pressure of the elements will

increase and the elements will get damaged. Be sure to inject

chemical with the pressure of lower than 10 kPa (100 mbar).

When injecting the chemical agents at the chemical cleaning,

please confirm beforehand that the modules are completely

submerged in the liquid and the liquid level of the membrane

submerged tank is higher by more than 300 mm than the top of the

module.

Please store the chemical agents in a dark cold place free from

direct sunlight.

Please use the appropriate tank or the container, for storing the

chemical agent, made of the material having enough corrosion

resistance to each chemical agent.

Don't mix sodium hypochlorite with acids, including oxalic acid or

citric acid; otherwise toxic chlorine gas is generated.

Don't mix sodium hypochlorite with heavy metals.

Please stop the scouring air during the chemical cleaning, or the

membrane elements might be damaged.
