Can our water filter bottle really do that?\u003c\/p\u003e\n\u003cp\u003eDon't be surprised: it's simply science.\u003c\/p\u003e\n\u003cp\u003eThe Baytiz water filter bottle owes its high filtering power to the design of its straw, built as a multi-stage filtration system.\u003c\/p\u003e\n\u003cp\u003eInside, we've integrated the world-renowned \u003cstrong\u003eUF Membrane\u003c\/strong\u003e ultrafiltration technology. We explain how it performs below.\u003c\/p\u003e\n\u003cp\u003eThis technology is paired with a filter barrier made of \u003cstrong\u003eactivated carbon\u003c\/strong\u003e, all reinforced by several microparticle filters.\u003c\/p\u003e\n\u003cp\u003eEach stage has a very specific role. Let's take a look together.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eUltrafiltration (UF) Membrane\u003c\/h2\u003e\n\u003cp\u003eUltrafiltration is a filtration method based on membrane separation. It uses semi-permeable (permselective) membranes capable of retaining solutes or particles contained in a solvent.\u003c\/p\u003e\n\u003cp\u003eThe principle is simple: the pores of our ultrafiltration membrane are around \u003cstrong\u003e1 nanometre\u003c\/strong\u003e. That's too small to let bacteria, yeasts and most viruses through (a bacterium measures on average around \u003cstrong\u003e3 nanometres\u003c\/strong\u003e).\u003c\/p\u003e\n\u003cp\u003eThe thickness of the membrane also plays a decisive role in increasing permeability, as shown by Poiseuille's law (cf. [J 2 790]).\u003c\/p\u003e\n\u003cp\u003eIn short, water molecules (H\u003csub\u003e2\u003c\/sub\u003eO) pass through the membrane, while bacteria, viruses and other microparticles are blocked.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eActivated carbon\u003c\/h2\u003e\n\u003cp\u003eWe've all heard of activated carbon: its properties are impressive.\u003c\/p\u003e\n\u003cp\u003eOften used in medicine, nutrition and cosmetics, it owes its popularity to its great capacity for \u003cstrong\u003eadsorption\u003c\/strong\u003e (not to be confused with absorption).\u003c\/p\u003e\n\u003cp\u003eAdsorption is a molecular reaction: activated carbon, in its solid state, binds molecules through Van der Waals forces.\u003c\/p\u003e\n\u003cp\u003eIt can adsorb many chemical molecules, such as:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003echlorine\u003c\/li\u003e\n\u003cli\u003emercury\u003c\/li\u003e\n\u003cli\u003elead\u003c\/li\u003e\n\u003cli\u003ebenzene\u003c\/li\u003e\n\u003cli\u003einsecticides\u003c\/li\u003e\n\u003cli\u003eherbicides\u003c\/li\u003e\n\u003cli\u003edetergents\u003c\/li\u003e\n\u003cli\u003esolvents\u003c\/li\u003e\n\u003cli\u003eand more than a hundred other substances…\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003c\/h2\u003e\n\u003ch2\u003ePP cotton barriers\u003c\/h2\u003e\n\u003cp\u003ePP cotton is mainly used to purify large quantities of water.
