What is Electrochlorination?

Electrochlorination is the process by which salt water is made potable for human consumption. This process works by running an electric current through salt water to produce hypochlorite. This solution is what provides the chlorination to make the water potable. Desalination is also used to make water safe for human consumption, showering, and swimming. If you’re considering desalination, here’s what you need to know.

 

Why is Desalination Important?

People who have been exposed to water that’s full of sediment or water that has viruses know that they’ll get sick. That’s why experts recommend drinking bottled water in third world countries because of the viruses present and the high salt content. To avoid illness, such as dehydration and high blood pressure, saltwater is inserted into the water or electrolyzer cells to begin the process of electro-chlorination.

Before this process is begun, solid excess must be removed from the saltwater. The saltwater will run through a channel of decreasing thickness. On one side of the channel is a cathode, and on the other side is an anode. The electrolysis process will produce sodium hypochlorite, and this will produce potable water after the hydrogen is removed from the process.

Are Chemicals Recommended for the Process?

Brackish water or brine may be found in seawater and need to be removed. Chemicals will help with the brine or brackish water. The random chemicals will not threaten the system and can be removed at the end of the process. The low voltage DC current is what’s necessary to begin the process of electro-chlorination.

After the process, the water should contain between 0.7 percent and one percent chlorine. Any chlorine concentration below one percent is considered non-hazardous and is considered an effective disinfectant as long as the sodium hypochlorite is between the pH range of six and 7.5.

In the past, the technology was used to prevent health threats such as cholera, dysentery, and typhoid. This chlorination process was voted one of the “most significant public health advance[ments] of the millennium.” Many people need to consider this technology if they want their drinking water to be safe for consumption, personal hygiene, and recreation. Many people have used the process to fill their pools with water that’s safe.

How Electrochlorination is Useful

Electrochlorination is useful in a variety of places including shipyards, homes with hot water heaters, and in other locations where corrosion may occur. The technology is useful and is recommended in a variety of situations. If you want to find out more about electro-chlorination, more information can be found by searching online.

How to Choose and Apply Anti Fouling Paint on Boats

Anyone familiar with boats and submerged structure is probably at least vaguely familiar with the biofouling. Biofouling is the growth and subsequent accumulation of biological matter on any part of structure that is in contact with water. Micro-organisms. Algae, and other forms of life can all quickly start to attach if the material is in contact with or under the water.

Such biofouling leads to an immense, industry-wide problem and expense: corrosion. The answer to this dilemma is anti fouling surface coating (also see antifouling system). In short, highly specialized paints are applied to the areas of structure in contact with the water. This paint is formulated to protect the surfaces from all types of bio-growth and corrosion.

The question for some then comes to involve choosing and applying the correct anti-fouling paint. Leading the industry in these specialty paints and processes are a select few providers. The anti fouling paints produced and used by these providers lead all other makes in durability in the field.

The process by which such coating companies apply these specialty coatings is also quite advanced. First, the structure is lifted or completely made physically accessible to technicians. From here, necessary surface preparations can be applied in advance of the coating. Once all surfaces test-out, the anti fouling paints can be applied. This is usually done using a variety of methods including machine-spray and human application. Finally, the surfaces are assessed and either additional coating is required, or the structure is deemed ready for underground and underwater utilization.

Those looking for additional assistance with biofouling, corrosion, and coatings are well-served to visit www.cathodicme.com. Here, a detailed breakdown of such processes and products is made available for those wishing to learn more. Above all others in the industry today, this particular provider is a top choice in biofouling and corrosion prevention and resolution.
