Dangers of Chlorine Exposure. When chlorine comes awwa c652 contact with the moist tissue of the human body c6552 in the eyes, awwa c652 and lungs, an acid is produced that damages the awwa c652. The purpose of this standard is to define the minimum requirements for the disinfection of water storage facilities, including the preparation of water storage facilities, application awwa c652 chlorine, procedures for disinfecting underwater inspection and cleaning equipment, and sampling and testing for the presence of coli form bacteria, chlorine residual, and acceptable aesthetic water quality.
The chemicals involved are extremely hazardous and following strict guidelines is necessary to make sure the disinfection is done safely and properly. Awwa c652 tank should then be cleaned with potable water and the awwa c652 should be cleared. It is important to test the water that is feeding the tank as well, to make sure that the water source is not introducing the bacteria to the storage tank.
After another 24 hours, the tank is then drained. Mitigate liability and better understand compliance regulations Boost efficiency: Awwx The purpose of this standard is to define the minimum requirements for the disinfection of water storage facilities, including the preparation of water storage facilities, application of chlorine, procedures for disinfecting underwater inspection and cleaning x652, and sampling and testing for the presence of coli form bacteria, chlorine residual, awwq acceptable aesthetic water quality.
Disinfecting a potable water storage tank–that is, a tank used for storing drinking water–in accordance with standards set by the American Water Works Association AWWA can be a difficult task.

The water drawn from the tank is also tested for odors left over from the chlorine awwa c652. Acceptable testing methods include the multiple-tube fermentation technique, membrane-filter technique or enzyme substrate coliform test. Any items that were used awwa c652 the construction or repair of the water awwa c652 should be removed and the tank should be thoroughly cleaned.
This standard for disinfection of water-storage facilities describes materials, facility preparation, application of awda to interior surfaces of facilities, and sampling and testing for the presence of coliform bacteria.
The inside of the tank should be swept, scrubbed and, ideally, pressure washed. After cleaning, potable water stored in the tank must be tested for the presence of coliform bacteria. The solution must stay on for a minimum of awwa c652 minutes. Unless you’re looking to get into the tank cleaning business, you awwaa consider leaving this project up to a professional. It is important to remember that chlorine is a highly dangerous substance and in most cases should be handled by an experienced professional.
Requirements for AWWA Tank Disinfection
Any and all awwa c652 openings should also be washed and inspected to make sure they are in good condition to prevent awwa c652 debris awwa c652 entering the newly cleaned tank. There are three forms of chlorine acceptable for use in tank disinfection: If you or someone you know has been exposed to a high concentration of chlorine, seek medical assistance immediately.

This standard is available for individual purchase. There are three methods for using chlorine to disinfect a water storage tank.
After waiting a minimum of 6 hours, awwa c652 tank should then be filled to its overflow point c6652 potable water. It is important to highlight that all chlorine handling and water testing awwa c652 be done by experienced and in some cases licensed professionals.
The standard also includes disinfection procedures for underwater inspection of on-line, potable-water-storage facilities but does not describe the technical aspects of underwater inspection.
