PREVENTION

 To prevent spread of the causative organisms  Preventing disease  Use of germs free drinking water

SAFE WATER

 Germs free water  Boiling of water  Sterilization of germs  Use of chlorine & its

compounds to destroy the germs

12931:2000)

 UNICEF Supply Codes For NaDCC TABLETS S 15350,S 158355

 THE GERMAN DRINKING WATER REGULATIONS

specify the use of NaDCC tablets for drinking water treatment.

 THE U.K SECRETARY OF STATE FOR THE

ENVIRONMENT, TRANSPORT AND REGIONS

have approved NaDCC Tablets in accordance with The Water Supply (Water Quality) Regulations 1989 No.1147, under Regulation 25(1)a, for the disinfection of water and water supply systems.

 THE FRENCH HIGH COUNCIL FOR PUBLIC

HEALTH, MINISTRY OF EMPLOYMENT AND SOLIDARITY, approved NaDCC Tablets for the treatment of

drinking water.

 Many DEFENCE FORCES specify NaDCC for water disinfection.

CHLORINE & COMPOUNDS

available for drinking water disinfection

 Sodium hypochlorite  Bleaching powder  Halazone 4-(dichlorosulphamoyl)

Benzoic acid i.e.Pantocid

 Chloramine t(sodium-n-chlorotoluene-4-

sulphonimidate trihydrate)

 Liquid chlorine

NADCC + H2O = HClO + Na+ + H2C4- HClO = H+ + ClO- HClO = HCl + [O] [O] + MICROORGANISM= HCl +OXIDISED MICRO ORGANISM (DEATH OF GERMS)

Hydrolysis of chlorine compound Formation of hypochlorous acid Stabilization of hypochlorous acid at the pH of water Decomposition of HClO to liberate nascent oxygen Oxidation & destruction of germs by nascent oxygen

Action

Action

 Underchloric acid (HOCl, which is electrically neutral) and hypochlorite

ions (OCl-, electrically negative)

 The cell wall of pathogenic microorganisms is negatively charged by

• nature. As such, it can be penetrated by the neutral underchloric acid,

rather than by the negatively charged hypochlorite ion.

• OCl-

HOCl

penetrates slime layers, cell walls and protective layer

MICRO ORGANISM

Less effective since negatively charged

action

The free available chlorine released by Na DCC (and other chlorine donors, including the chlorinated isocyanurates) in solution will OXIDISE MANY ORGANIC AND INORGANIC COMPOUNDS IN WATER. Of particular significance are:

Ammonia Organic nitrogen compounds (amides, amines etc.) Proteins Total organic carbon Multiple C-C bonds, aromatic rings and carbonyl groups Nitrites Iron Manganese Hydrogen Sulphide Cyanides

OTHER USES OF EF-CHLOR

 Water treatment .  Steralizing equipments of medical through formation of instant

hypochlorous acid.

 Steralizing various products in household usage.eg; baby

bottles,vegetables,etc.

 Swimming pool water treatment.  Poultry farms.  Disinfection of water from various sources in flood affected areas

and in case of emergency .

 For bleaching of clothes.

In comparision to Calcium Hypochlorite

 Calcium hypochlorite has to be dissolved into the water by vigorous

• stirring. It is not readily soluble. Indeed, it contains calcium carbonate

(chalk) and other insoluble impurities, which deposit into the water making the solution cloudy and deposits cause scale formation in pipework and pumping systems, causing blockages.

 The product had the capacity to kill over 100 times more

microorganisms than calcium hypochlorite, under adverse conditions.

In comparision to Calcium Hypochlorite

In comparision to Calcium Hypochlorite

 Halazone has a short shelf-life of 5 months when

stored at 32°C.

 It loses 75% of its activity when exposed to air for

2 days (13).

 Drinking water standards require the absence of

coliform bacteria. This was not achieved using Halazone Tablets. NaDCC tablets achieved zero count.
