What is water purification?


Water purification is the process of removing unwanted, or unsafe chemicals, impurities, biological contaminants, solids and gases from contaminated water, in order for it to be consumable and to remove any threat to your health. Even if water looks clear, it can contain microscopic contaminants that can cause great harm. Here are RM Supply we provide high-quality water purification products to buyers across Scotland, the UK and even globally, including:



How do water purification products work?


Water purification meters can be used to test the quality of your water. Water purification tablets will then make it safe for drinking, cleaning teeth, washing wounds, washing fruit and vegetables etc. This is achieved by killing the water-borne organism that causes stomach disorders such as diarrhea, cholera and typhoid. Our water purification products are manufactured to an effervescent formulation containing sodium dichloroisocyanurate (NaDCC). This is an organic chlorine donor with a superior disinfection capacity to sodium hypochlorite, a near-neutral pH and a simple, easy-to-understand closing system for added safety.


Effervescent chlorine tablets are recommended by various aid organisations, including the World Health Organisation, who include them in their Interagency Health Kit.  To use, you simply add one tablet to one-liter of suspect water for rapid disinfection – after several minutes your water will be safe to consume, wash in or clean with.


Who should buy water purification products? 


Water purification products are not just for use by big businesses, but can be used on holiday, when travelling on business, while camping or in emergencies when the only water nearby is of questionable quality.
