Water treatment plants are critical infrastructure for providing clean and safe drinking water to communities. One key component of the water treatment process is the disinfection of water, which is often achieved through the use of sodium hypochlorite. Sodium hypochlorite is a powerful disinfectant that is widely used in water treatment plants around the world.
In this blog, we’ll discuss how sodium hypochlorite is used in water treatment plants, best practices for storing it, and guidelines for safe handling.
Sodium Hypochlorite is a corrosive chemical with the formula name NaCIO. It is a powerful oxidizer and is often used as a bleach and a disinfectant, and here at Polymaster we often supply tanks for this chemical to be used in the water treatment plants and industries.
Let’s take a look at 5 key questions that get asked when Sodium Hypochlorite is being used and how to safely store this chemical when it comes to water treatment.
In the water treatment industry Sodium hypochlorite is used to purify and disinfect water. It eliminates harmful microorganisms, such as bacteria, viruses, and parasites. When Sodium Hypochlorite is added to water it starts a process called chlorination. This process is commonly used in municipal water systems, swimming pools or other water sources to ensure the water is safe to drink and use for humans and the environment.
It can also be used to remove things such as dissolved iron, manganese, and hydrogen sulphide from the water. These are substances that give the water an unpleasant taste and odour, they can also stain clothing and fixtures.
It also controls algae and other organic growth in reservoirs, water tanks, and other water storage facilities.
The overall dosage of Sodium Hypochlorite is based on the condition of the water being treated and the level of microorganisms within the water. This is usually dosed in small amounts with the chlorine residue being monitored to maintain a safe level.
Sodium hypochlorite is a highly reactive and corrosive chemical that requires special handling and storage. It’s important that it’s stored within a container that is resistant to corrosive chemicals. This means within a tank or container that is built for the purpose of holding aggressive chemicals.
Polymaster Self-Bundled and process tanks are excellent for storing corrosive chemicals such as Sodium Hypochlorite. Our tanks have a specific gravity of 2, even though you only need up to 1.5SG and are UV stabilised. These tanks are chemical resistant and are not prone to corrosion that can occur when storing a chemical like this one.
If you were to put this chemical within a normal poly rainwater tank with a lower SG of 1 it would essentially dissolve the poly and you’d be left with leaks and need to find new storage.
Polymaster has a dosing skid that can assist to control the flow rate of Sodium Hypochlorite used to treat the water within any water treatment set-up. The dosing skids offered by Polymaster meet or exceed water treatment authority specifications. The systems allow direct PLC (SCADA) communication allowing fill safety, level reporting and flow adjustment.
It is important to regularly inspect and check your tank for any signs of damage or wear that may occur and get them repaired immediately.
When it comes to storing Sodium Hypochlorite, what you are storing it with is just as important as you can cause serious harm to people on-site or the environment around you. Sodium hypochlorite should not be stored with acids or any other chemicals that can react with it.
The following chemicals should not be stored with sodium hypochlorite:
When it comes to the storage and handling of Sodium Hypochlorite it’s important that it is handled safely, and that everyone on-site is kept safe. Here are a few guidelines to follow to keep your workplace safe:
It’s important to highlight that guidelines may vary depending on the specific water treatment process and location of the site. Always be aware of your site’s regulations and requirements when it comes to water treatment.
Sodium hypochlorite is an essential component of water treatment plants that helps ensure the delivery of safe and clean drinking water to communities. Proper storage and handling of this powerful disinfectant is crucial to maintain a safe and healthy working environment for water treatment plant employees and protecting the public from potential health hazards. By following the guidelines outlined in this blog, water treatment plant operators can ensure the safe and effective use of sodium hypochlorite in their facilities.
