What is Shock Chlorine and how is it used?

WHAT IS SHOCK CHLORINE

Shock chlorine is the common name for Calcium hypochlorite, a powder chemical with the formula Ca(ClO)2. It is widely used for water treatment and as a bleaching agent (bleaching powder). This chemical is considered to be relatively stable and has greater available chlorine (65%) than sodium hypochlorite (liquid bleach).

  • Other names: Hypochlorous acid, calcium salt / Bleaching powder / Calcium Oxychloride, shock chlorine
  • CAS No: 7778–54–3
  • EC No: 231–908–7
  • UN No: 1748
  • Appearance: white or grey/white powder with odour of chlorine
  • Molar Mass: 142.98 g/mol
  • Density: 2.35 g/cm3
  • Melting Point: 100oC

Uses for Shock chlorine

SHOCK CHLORINE FOR USE IN SWIMMING POOLS & SPAS:

Calcium hypochlorite is used for the disinfection of drinking water or swimming pool water. For use in outdoor swimming pools, calcium hypochlorite can be used as a sanitizer in combination with a cyanuric acid stabilizer. The stabilizer will reduce the loss of chlorine because of UV radiation. Calcium does make the water hard and tends to clog up some filters. However, some types of calcium hypochlorite do contain anti-scaling agents in order to prevent clogging up of pipes/filters. This grade of calcium hypochlorite can also be used in hard waters. The main advantage of calcium hypochlorite is that it is unstabilised unlike chlorinated isocyanurates such as sodium dichloroisocy­anurate or trichloroisocy­anuric acid. Latter products do contain cyanuric acid. If the level of cyanuric acid becomes too high, it will influence the performance of the chlorine.

Pools running on calcium hypochlorite should have a chlorine level of 1–2 ppm (mg/L).

Calcium hypochlorite is also used for bleaching cotton and linen and is used in the manufacture of chloroform.

For whitening in laundry one normally uses approx 200mls of 5% bleach per load. As the calcium hypochlorite is 65% chlorine then you will need around 15g of the calcium hypochlorite per wash. alternatively you can make a 5% solution by adding 77g of calcium hypochlorite to 1 litre of water and use 200mls of this solution.

Other uses are:

  • As a bathroom cleaner
  • For Cleaning secondhand items
  • Adds glow to glass dishware
  • As a Household disinfectant spray
  • It remove moss and algae from paths, patios and driveways
  • Use to sanitize garden tools
  • Kills weeds in walkways
  • Preserves and keeps cut flowers fresh
  • Can be used to Clean garden furniture,

Disinfecting drinking water with Shock Chlorine:

Calcium hypo is used extensively throughout the world to purify drinking water and make it safe. you can either add it directly into water or make up stock solutions to use to treat batches of water. The first is better as stock solutions will deteriorate with time.

As a simple rule of thumb add 0.5g of solid calcium hypochlorite to 100 litres of water (dissolve the 0.5g in about 1 litre of water first and then add this to the 100 litres).

CLASS C: Oxidizing material. CLASS E: Corrosive solid.

R22– Harmful if swallowed. R38– Irritating to skin. R41– Risk of serious damage to eyes.

What is Sodium Dichloroisocyanurate and what is it used for

What is Sodium Dichloroisocyanurate

Sodium dichloroisocy­anurate is the sodium salt of a chlorinated hydroxytriazine and is used as a source of free available chlorine (in the form of hypochlorous acid, HOCl) for the disinfection of drinking-water. A special high active powder containing 65% chlorine which slowly releases chlorine into swimming pools and spas. Stailised to prevent deteriorating effects of sunlight. Easy to dissolve granules that sanitise and disinfect water removing bacteria and algae. It also removes grease and oils helping to keep pool water clean and healthy.

  • Other names: Sodium DiChloroisocy­anurate dihydrate; Stabilised chlorine; sodium 3, 5-dichloro-2,4,6-trioxo-1,3,5-triazinan-1-ide; sodium troclosene; troclosenum natricum; NaDCC;
  • CAS No: 51580–86–0
  • EC No: 220–767–7
  • UN No: 3077
  • Mol Formula: C3Cl2N3NaO3
  • Appearance: white granular solid with odour of chlorine
  • Molar Mass: 219.95 g/mol
  • Density: 0.7 g/cm3
  • Melting Point: 225oC
  • Solubility: soluble in water 250g/L
  • pH: 6–7 (1% aqueous solution at 25C)

Uses for Sodium DiChloroisocy­anurate

  • Contains 65% available chlorine.
  • Rapidly dissolving granules, which go to work immediately.
  • Release chlorine in low concentrations by constant rate.
  • Sanitizes and disinfects, removes harmful bacteria and prevents algae, mould and fungi forming.
  • Used to sterilise drinking water.
  • Used to chlorinate swimming pools and spas (see below for more info).
  • Used as a disinfectant in raising silkworm, livestock, poultry and fish.
  • Industrial applications include bleaching of textiles.

How to use Sodium DiChloroisocy­anurate in pools and spas

Chlorine levels of pools and spas should be maintained from 1–3 mg/L and the pH from 7.2 – 7.6.

To raise the level of free chlorine by 1 part per million or 1mg/L for every 10000 litres of water add 12.5g of Stabilised Chlorine granules. Dissolve the granules in a container and add by dosing into the skimmer or via a pump. Do not use pool until level of chlorine in pool returns to 1–3mg/L.

Health & Safety

Risk Phrases: R8– Contact with combustible material may cause fire. R22– Harmful if swallowed. R31– Contact with acids liberates toxic gas. R36/37– Irritating to eyes and respiratory system. R50/53– Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
