Fire-Fighting bolted steel water tanks must be disinfected regularly. The first is to protect the water tank. The second is to protect the water quality of the water tank,
When using the high level Fire-Fighting bolted steel water tanks, in order to ensure that the water quality meets the use requirements, the water in the tank needs to be disinfected regularly and the disinfection steps should be strictly implemented.
Fire-Fighting bolted steel water tanks is very important to prepare high level fire water tank before disinfection. Protective equipment such as overalls, masks, goggles and safety lighting must be provided. Check the integrity of high-pressure Fire-Fighting bolted steel water tanks gun pump, blower, etc., and check whether the bactericide is within the validity period.
Then check the power of the work. When the water tank is running, the voltage of lighting power supply shall not exceed 36V, and Fire-Fighting bolted steel water tanks is better to use emergency light or flashlight; the three-phase water pump shall be equipped with leakage at the beginning.
Fire-Fighting bolted steel water tanks is also necessary to check the anoxic box. Some water tanks are closed for a long time, the air flow is almost stagnant, and people will suffocate due to lack of oxygen if they are eager to enter. Therefore, the blower can be connected to the high fire water tank.
Ventilation time shall be 3 hours. After emptying, put a burning candle into the box. If the candles don't go out, there's no oxygen in the pool. Otherwise, continue to ventilate until it meets the requirements.
Fire-Fighting bolted steel water tanks according to the standard rules of fire protection technology, the static pressure of the asphyxiation ignition bolt shall not be less than 0.07MPa, and the working pressure of the nozzle at the asphyxiation point shall not be less than 0.05Mpa.

In practice, FRP tanks usually need booster pumps to meet the pressure requirements. Some planners use the booster pump outlet pipe as the outlet pipe of FRP tank, which is a very wrong way. This is because the main purpose of the booster pump is to meet the water pressure requirements of the fire hydrant and the active sprinkler system before the fire pump is started.
The hydrant water supply system shall not exceed 5L / s. The sprinkler system shall not exceed 1L / s,Fire-Fighting bolted steel water tanks is obviously lower than the indoor fire water required by the standard, and cannot meet the repair requirements of the initial fire water volume.
Therefore, the booster pump installed on the roof shall be provided with a bypass pipe on the outlet pipe side of the booster pump. The flow rate of water shall not be less than the amount of water required to remedy the initial fire
