Sodium Hypochlorite

"Have you been looking for a reliable water disinfection solution? A robust treatment regime that gives you the results you are looking for?"

Dosing with sodium hypochlorite is money down the drain. Find out why.

Have you been looking for a reliable water disinfection solution? A robust treatment regime that gives you the results you are looking for?  At Nanotech, we have the alternative disinfectant to the age-old sodium hypochlorite dosing solution. Our disinfectant is far better at addressing your problems.

We can replace your sodium hypochlorite treatment with a disinfectant solution that really works. In fact, the only reason sodium hypochlorite is so widely available as a disinfectant is because it is a by-product of the main process of producing chlorine gas.

Do you want some by-product like sodium hypochlorite to form the basis of your disinfection regime or a product that was formulated from the outset to be a disinfectant? That is why our award- winning technology in chlorine dioxide is fast becoming the disinfectant of choice.

So many of our clients tell us about their challenges and the prohibitive cost of the chemicals they are currently using – and which are simply not giving them the results they are looking for. Does your disinfectant add value or is it just costing you money? Are you looking for something better? If you could get top results for once at a price that does not break the bank, wouldn’t that be absolutely worth it?

We can offer you alternative, scalable disinfectant solutions that offer you peace of mind. Over many years, Nanotech has positioned itself as the technology leader with a knack for understanding clients’ problems and solving them with an array of advanced technologies. It all comes down to ensuring clients get the results they need.

We have the ideal disinfectant for microbial control and residual challenges covered for clients in all these industries:

  • Water utilities
  • Food and beverage
  • Abattoirs
  • Farming
  • Hospitals
  • FMCG
  • Hospitality
  • Aviation

With our in-depth understanding of which technologies to deploy, combined with our expertise in understanding process requirements, we can resolve your problems and meet all your challenges.

Our sodium hypochlorite alternative can offer you:

  • Improved safety for your employees;
  • Less human intervention;
  • A more autonomous experience;
  • An integrated process;
  • Excellent results; and
  • Lower Hazchem transport costs.

Why do people use sodium hypochlorite?

The common misperception is that sodium hypochlorite is an effective disinfectant with a broad range of applications, which is why it is so commonly used in water-treatment systems. On the face of it, it appears to offer the best mix of low cost, ease of use, safety, and efficacy in areas where there is enough water that is not excessively turbid to drink. But this is not accurate.

Why does sodium hypochlorite struggle to maintain a residual?

When sodium hypochlorite dissolves in water, two substances form that both play a role in oxidation and disinfection. These are hypochlorous acid (HOC?) and the less-active hypochlorite ion (OC?-). In potable-water applications with a pH of 7,5 to 8,5, between 50 and 90% of the sodium hypochlorite solution converts to the hypochlorite ion, the less-active component and hence, the one that is relatively poor at maintaining a residual and achieving the results you seek.

Why is Hypochlorite so corrosive?

Because of the high pH of sodium hypochlorite, it attacks metals. It also generates hydrogen gas when coming into contact with aluminium.

Why is Hypochlorite so expensive?

  • As soon as sodium hypochlorite comes into contact with water, it hydrolyses, immediately losing much of its efficacy.
  • It is a non-selective disinfectant and reacts with metals and organics in the water. Therefore, most of it ends up not being used for its intended disinfection purpose, leaving one to dose more and more in order to see results.
  • Sodium hypochlorite can degrade significantly within two to three weeks so, if purchased in bulk, within a month it becomes relatively ineffective and you would have to overdose to get the same residuals as at the initial dosage set points. This is when it becomes an expensive exercise.

Why does Hypo form so many disinfection by-products (DBPs)?

It readily reacts with inorganic and organic materials and forms up to nine different disinfection by-products.

Why do I experience scaling when dosing with Hypochlorite?

The high pH of hypochlorite reacts with calcium and magnesium in diluted water that precipitates as carbonate scale.

Why are my maintenance costs so high when dosing with Hypochlorite?

  • It readily attacks metals and, over a period, you would experience issues throughout your processes and reticulation.
  • Normal glue uses fumed silica (finely ground glass) as thickening. The high pH of the hypochlorite solution can dissolve the silica, leaving the glue joint porous and susceptible to leaks.

Why is it not safe?

  • Mixing anything with hypochlorite can be extremely dangerous. Contact between hypochlorite and other treatment plant chemicals such as alum, iron-based  [Ci1] compounds, or sodium bisulphate can cause an uncontrolled, explosive release of energy, heat, and chlorine gas.
  • Unless flushed, drained, or vented, offline equipment may build up significant pressure from gasification that may be released explosively.
  • Splashes, spills, and leaks may occur. When hypochlorite comes into contact with clothing, it causes bleaching and holes.

You just want something that works, so that you can focus on running your company. At Nanotech, we have the perfect balance of technologies, engineering expertise, support and an understanding of clients’ processes to make a huge difference to your disinfection and water treatment requirements.
