Edulab Blog Water Purifiers: An Introduction

Water purifiers are a convenient way of filtering any biological contaminants, unwanted chemicals, suspended solids or gases from contaminated water. This may be useful in many different experiments in a variety of chemistry, biology or physics disciplines.Here at Edulab, we sell 3 different types of purifier:RO UnitsGenerally, RO purifiers such as the ISG Fusion work using a variety of technologies to purify water. These include:Pre-treatment;Reverse osmosis - The water is passed through a semipermeable membrane to help filter out any ions, molecules or any larger particles;UV photo-oxidation;Ion exchange - The water is then passed through an electrolyte complex to help further remove any ions that may still be in the water. (We also offer EDI technology instead of ion exchange if you'd prefer); Sub-micron filtration - And finally, this helps purify out lead, mercury, asbestos, cysts and several types of bacteria.While many water purifiers tend to only do one of two of these things, our ISG Fusion RO Units do them all. We also offer two other types of water purifier in our online store:DeionisersWater deionisers are a great choice if you are on a tight budget. Where RO Units incorporate several purification technologies, deionisers utilise only one: When water is pumped into it, the liquid is passed through a specially-designed resin cartridge which changes colour when ions are filtered out from the water.StillsThe other option for water purification is water stills: These units use an internal heating element to help filter out any bacteria or biological matter from the water. They are also another great budget option for when working with tight budgets.
