What is Sodium Hypochlorite?

Sodium hypochlorite releases chlorine in water, which disinfects quickly and leaves a measurable residual. It is the most common way to disinfect treated sewage that is reused for flushing or gardening, and to disinfect storage tanks and raw water.

Its strength falls over time, faster in heat and sunlight, so it should be stored cool and used fresh. Chlorine must be removed with SMBS before any RO membrane.

Where Sodium Hypochlorite is used

  • Disinfection of STP and ETP outlets for reuse
  • Raw water and tank disinfection
  • Cooling water as an oxidising biocide
  • General sanitation

How to use Sodium Hypochlorite

  1. Dose into a contact tank so the water has enough contact time.
  2. Measure residual chlorine at the outlet and adjust.
  3. Store in a cool, shaded place in closed containers.
  4. Dechlorinate with SMBS before RO or where discharge limits require it.

Frequently asked questions

Why does sodium hypochlorite lose strength?

It slowly decomposes, faster in heat and sunlight. Store it cool and shaded in closed containers and use it within a reasonable time.

Can I use hypochlorite before an RO plant?

Yes for disinfection upstream, but the chlorine must be removed with SMBS before the water reaches polyamide RO membranes.
