Tank Disinfection

Tank disinfection is a key component of water systems in homes and various establishments. Tanks are used to store water and provide it when needed, but over time, sediments and microorganisms may accumulate inside the tank, leading to water contamination and degradation of its quality. The importance of periodically disinfecting tanks lies in ensuring the health of the water and the safety of individuals who use it.

Disinfection is the process of removing dirt, deposits, organic materials, and microorganisms from the tank, in addition to cleaning the tank walls and cylinders of rust and mold. The goal of this process is to ensure that the stored water is safe for human use and does not pose any health risks.

Tank Disinfection

Tank disinfection is a necessary process aimed at cleaning and sanitizing water tanks to ensure the quality of stored water and protect it from contamination. In this process, sediments, rust, impurities, and harmful bacteria and fungi are removed, which affect the health of the users. Periodic tank disinfection helps prevent waterborne diseases and ensures that the water remains safe for human consumption.

Stored water in tanks can contain harmful bacteria, fungi, and microorganisms if not disinfected regularly, which may lead to gastrointestinal or skin diseases. The accumulation of dirt and sediments in the tank can damage the tank’s interior materials and degrade the water quality. Rust can cause pipe blockages and contribute to water contamination.

Disinfecting tanks enhances the quality of stored water and ensures that no contaminants affect the taste or odor of the water. By disinfecting the tanks regularly, the tank’s walls remain intact and safe, which increases its lifespan and reduces the need for maintenance or replacement.

First, all water sources should be closed, and the tank should be completely emptied.
After emptying the tank, clean the interior walls using brushes or specialized cleaning tools to remove accumulated sediments and dirt.
If the tank contains rust buildup, special chemicals or oxalic acid can be used to remove rust and clean the metal surfaces.
After cleaning, the tank should be disinfected using a bleach solution or other disinfectants to kill bacteria and viruses. The tank is filled with the solution and left for 30 minutes to an hour. Then, the solution is drained, and the tank is thoroughly rinsed with clean water.
After disinfection, the tank should be washed multiple times with clean water to ensure any remaining bleach or other chemicals are removed.
Once the tank is confirmed to be dry and free from contaminants, it can be refilled with clean water.

Chlorine Disinfection of Drinking Water Tanks

Chlorine disinfection of drinking water tanks is an effective method to ensure water purity and protect it from bacterial contamination. Chlorine is one of the most commonly used chemicals for water disinfection because it is capable of killing bacteria, viruses, and parasites that may be present in the tank. Using chlorine to disinfect tanks helps prevent waterborne diseases, such as gastrointestinal illnesses and poisoning, that are caused by contaminated water.

First, turn off the water supply to the tank and completely empty it of any water. Ensure that all old water and any sediment at the bottom of the tank are removed.
Clean the interior walls and cylinders of the tank using a stiff brush or scraper to remove accumulated dirt and sediments. You can use a mild solution of water and vinegar or soap to clean the surfaces.
Use a bleach solution containing 5-6% chlorine, typically available in the market as liquid bleach or chlorine liquid. To prepare the chlorine solution, mix 100 ml of liquid chlorine with 10 liters of clean water. The ratio may vary depending on the tank size or the condition of the water.
Pour the prepared chlorine solution into the tank. Ensure the solution is evenly distributed over all the interior surfaces of the tank.
It is important to fill the tank completely with the chlorine solution, ensuring that all walls of the tank are fully covered.
After adding the chlorine solution, leave it in the tank for 30 minutes to an hour, depending on the size of the tank and the condition of the water. During this time, it is recommended to cover the tank to reduce evaporation and ensure effective disinfection.
After the disinfection period, empty the tank of the chlorine solution completely.
Wash the tank thoroughly with clean water several times to remove any remaining chlorine or other chemicals.
After confirming that the tank has been fully cleaned and disinfected and is free of any chemicals, refill the tank with clean water.
Ensure that the water used to refill the tank is pure and of high quality.
It is important to use the correct amount of chlorine. Using too much chlorine can contaminate the water or affect its taste and smell.
During the disinfection process, make sure the tank is in a well-ventilated area to avoid inhaling chlorine fumes.
Tanks should be disinfected regularly, at least every 6 months, to ensure that the water is always healthy and safe for use.
After disinfection, you can conduct a water test to ensure that the water is free from any chemicals or contaminants that may affect health.

The Necessity of Tank Sterilization

Sterilizing tanks is one of the essential processes that cannot be overlooked to ensure the purity of drinking water and maintain its health. Water stored in tanks provides an ideal environment for the accumulation of dirt, sediments, bacteria, and fungi, which leads to water contamination and exposes individuals to the risk of diseases. Therefore, sterilizing tanks becomes a necessity to ensure that we receive water that is safe and fit for use.

Tanks that are not cleaned and sterilized regularly are prone to the buildup of microbes and germs, such as bacteria and fungi, which increases the risk of microbial contamination. Contaminated water can cause gastrointestinal diseases, such as diarrhea and food poisoning, as well as other diseases like enteritis and acute poisoning.
Tanks are used to store water; however, some contain minerals and salts that may settle at the bottom and cause sediment accumulation and rust on the internal walls. These deposits not only present an undesirable appearance but also affect the taste and smell of the water, in addition to causing pipe blockages.
Sterilizing tanks helps maintain the purity and quality of water. When the tank is cleaned and disinfected regularly, organic materials and harmful bacteria are removed, thus preserving the fresh and pure taste and smell of the water. Contaminated water may acquire an unpleasant taste or become unfit for consumption.
Sediment and rust buildup leads to damage to the tank’s surfaces and affects its structure. Regular sterilization helps maintain the walls and prevents deterioration, thus contributing to prolonging its lifespan and reducing maintenance or replacement costs.
Sediments and accumulations inside the tank can cause blockages in valves and pipes or even water leakage. Sterilizing the tank helps prevent these issues, which can be costly to repair.
Sterilizing tanks has a positive impact on the entire water system, whether in homes or facilities. When the tank is cleaned regularly, the system remains free of contaminants, improving water flow and quality throughout all connected pipes.
Use a strong brush or specialized tools to remove sediment and rust from the tank’s walls.
Use a solution of chlorine or other disinfectants to sterilize the tank and kill any bacteria or viruses.
After disinfection, the tank should be washed several times with clean water to ensure that any chemical residues are removed.
