Human survival depends on the availability of safe drinking water. According to the World Health Organization (WHO), 88 % of the 4 billion annual cases of diarrheal disease can be attributed to unsafe water and inadequate sanitation. Unsafe drinking water may contain serious health threatening bacteria like cholera, typhoid, or dysentery. It is estimated that 1,8 million people die from these diseases each year. Access to safe drinking water is a major problem after natural disasters, military actions, calamities et cetera. International aid organizations like the IDA Foundation, distribute disinfectants in emergency health kits for treating drinking water in disaster areas.    

Professional treatment of drinking water is mostly done with chlorine containing products. These products are available as liquids or in solid form (granules or tablets). The most reliable and stable form are chlorine tablets.

VEIP disinfectants can produce chlorine tablets in any size or form, either rapid release-tablets or effervescent dissolving tablets. Our time to delivery is very short, which is important in emergency cases.

VEIP disinfectants chlorine tablets: Halamid and Actisan

VEIP disinfectants represents two different actives for drinking water purification (see table).

Both products can be used for:

• Drinking water disinfection (e.g. water reservoirs in homes; water tanks in ships, aircraft or mobile homes)
• Shock treatment of heavily polluted (surface) water (e.g. after a natural disaster)
• Disinfection of surfaces and equipment

Advantages of chlorine water disinfection

The chlorine products in the table above have several advantages in comparison with other disinfectants for water treatment.

• These chlorine products are effective against a relatively wide spectrum of pathogenic micro-organisms like bacteria and viruses (with the exception of myco-bacteria, that need a higher dosage of chlorine).
• Chlorine is an oxidative disinfectant. Since its reaction with organic material (bacteria, yeast, fungi, viruses) is irreversible, it cannot cause any resistance of pathogenic micro-organisms.
• The disinfection procedure can easily be controlled by using potassium Iodine testers for measuring the available active chlorine before, during and after disinfection.
• Provided that it is used in the right way and with the correct dosage, chlorine is not toxic for human beings, animals or nature in general: the chlorineis completelyused up in the reaction with organic material andthe sodiumis reversed into harmless salt.The other molecules are quickly bio-degradable by micro-organisms. In other words, the natural balance in waste water systems, sewage systems or nature itself will not be harmed.

 Advise for cleaning and disinfecting water tanks (normal circumstances)

Even in ordinary circumstances, you need to clean and disinfect your empty water tanks and distribution system in cars, ships or aircraft (and water reservoirs in houses and living areas) on a regular basis. This may vary from once a week in case of a higher risk level (e.g. during an epidemic) to once a year (e.g. before leisure use of motorhomes and boats).

1. First, clean the tank. Water systems can be polluted by limestone and other mineral scale that may harbor bacteria. Remove these sediments with acid cleansers, for instance a cleaner with phosphoric acid (Texarin). Always rinse after cleaning.
2. Then, use Halamid or Actisan for disinfection. This disinfection solution needs some time (approximately 15 minutes) to be effective. Afterwards, rinse with clean water.

Advise for water treatment (heavily polluted water; after calamities)

Drinking water is not always available or reliable. In case of calamities, disaster or the highly contaminated water, take the following steps:

1. Filter the water to obtain optically clean water.

2. Chlorinate the water and double the normal dosage and contact time. For instance, if the preventive dosage is 5 ppm and the contact time is 30 minutes, you need to apply 10 ppm and wait an hour for the water to become potable. 

Dosages, contact time in case of disinfecting drinking water

Calculating the correct dosage

Use this formula to calculate the number of tablets you need:

(W x N)/(% active chlorine)= Y mg active (free) chlorine;

Number of tablets= Y/(weight of the tablet minus inert additives)

Example for Halamid tablet 550 mg (500 mg of chloramine-t)     

W =  litres of water to be disinfected: 1000 litres

N = 5 ppm

Y = (1000 x 5)/0,25 = 20000 mg

You need 20000/500= 40 tablets
