Swimming Pools
Sodium hypochlorite is widely used in swimming pools to disinfect the water and to oxidize pollutants in the water. It is the most commonly used chemical for these purposes in swimming pools.

Cooling water
Pretreatment of cooling water is necessary to prevent several kinds of biofouling of a cooling water system: piping, heat exchangers, cooling towers etc. Additional concerns may arise over the potential environmental and health impacts of Aerosols i.e. legionella pneumophila.

Disinfection of drinking and process water
Drinking water and process water are produced from ground water or surface water. Especially the latter contains large amounts of micro-organisms, some of them pathogenic. The water needs to be disinfected to prevent pathogenic micro-organisms to infest the water distribution system and to prevent biofouling.
In many European countries sodium hypochlorite is used for the disinfection of drinking water. The Netherlands is an exception to that rule.

Wastewater treatment
Sodium hypochlorite is mainly for polishing in this segment. After most impurities have been removed by other technical means such as biofiltration and just before discharge, wastewater is treated with sodium hypochlorite.

Cleaning and disinfection of installations
Cleaning and disinfection of installations with, a.o., sodium hypochlorite is a well known practice in the food, beverage, and dairy industry.

Production of cleaning and disinfecting agents
Sodium hypochlorite is used in many products for household cleaning, mainly for hard surface cleaning and disinfection. Other uses are industrial cleaning (food and beverage industry, kitchens and catering), institutional cleaning (floor cleaning), and industrial laundry cleaning (e.g. washing of clothing for hospitals).

Bleaching
Bleaching is generally understood to mean the chemical destruction of chromophores in organic or inorganic compounds.
Usually the aim is to increase the brightness by weakening or removing the color of the material being bleached. Decolorization is often combined with purification or cleaning. In the textile and pulp & paper industries sodium hypochlorite is often used for bleaching purposes.

Selective oxidation of starch
The use of regular starch is limited by its physical en chemical properties. Hypochlorite oxidation of starch is one of the most useful reactions developed for the modification of starch. Oxidation introduces an increasing number of carbonyl and carboxyl groups into the starch molecules, which in turn cause changes in the chemical and physical properties.
