Ozone Wastewater Treatment

Ozone Wastewater Treatment isn’t talked about much but is something of a fantastic treatment when we want to tackle and treat industrial wastewater. If a business generates the likes of suspended solids, nitrogen, odorous by-products (especially if sulphur is involved) and pesticides, ozone treatment may be a suitable treatment for helping with wastewater management.

When a business gains access to this type of treatment, it can see the cost of processing waste material go down, but this is dependent on the industry and whether ozone can provide the best level of disinfection (again, this is all down to industry and waste make-up).

Here is everything you need to know about ozone wastewater treatment and why it may be a good option for your business.

How ozone wastewater treatment works

Ozone wastewater treatment uses ozone gas to break down and eliminate bacteria when it is dissolved in wastewater. Ozone gas is made up of three oxygen atoms, rather than two, and will usually be charged electronically. With this extra atom, the gas can hit cell membranes in bacteria and cause them to split open. And when you do that, the “dodgy” cells die.

If you pass enough ozone gas through water, you can break down harmful products at various stages, making it ideal for treating:

  • trade effluent
  • digested sludge
  • biogas odours
  • filtration
  • disinfection

The benefits of ozone will vary by industry.

Are there limitations to ozone treatment?

Obviously, with the intense use of oxygen molecules, internal systems would want to avoid oxidisation on materials and corrosion where possible. Anyone interested in adapting their systems for this treatment type would expect a full audit of their internal network.

Ozone treatment also typically relies on ozone being created on-site, due to the short half-life it has making it difficult to transport.

Are ozone treatments efficient?

Ozone wastewater treatments can prove quite beneficial when compared to other treatments like chlorine, UV disinfection, or fluorine; the latter being extremely effective but frowned upon in many areas.

This treatment also has the advantage of being friendlier to the environment, as it doesn’t need to create pollutants in the treatment process and can see greywater is a condition where it could potentially be used re-used in internal systems.

Can ozone wastewater treatment be used as a disinfectant?

Yes. Ozone works quite resourcefully to hit at the cell membranes of waste solids when compared to using something like chlorine or UV as your disinfectant.

Why would a business want to use ozone wastewater treatments?

If a business wanted a safer and highly effective wastewater treatment, there’s not much out there which can beat ozone.

It’s a quick process, doesn’t produce any harmful residues which need accounting for in effluent, is more effective than traditional methods, and doesn’t affect water balance.
