How water treatment works, in plain words.

Three short, simplified explainers, and the words you’ll meet when you choose a system.

How reverse osmosis works

Water passes. Most salts don’t. Raise the pressure and watch the flow turn round.
How a softener works

Tiny resin beads swap the minerals that cause scale for sodium.

Words you’ll meet

Reverse osmosis (RO): A very fine membrane that holds back most dissolved salts while water is pushed through it under pressure.
TDS: Total dissolved solids: the amount of minerals and salts dissolved in water.
GPD: US gallons per day: how much treated water a unit or a plant can make in a day. Ask us about the amount you need.
Softener: A unit that swaps the minerals that cause scale for sodium, on tiny resin beads.

Osmosis: Water moving through a membrane towards the saltier side.
Membrane: A very thin sheet that lets water through and holds back most dissolved salts. In a purifier it is rolled up inside a cartridge.
Pre-treatment: The first stages, which catch sand and particles so the membranes last longer.
Concentrate: The water that carries away what the membrane holds back, through the drain line.
Scale: The hard, chalky layer that hard water leaves in pipes, heaters and appliances.
Resin: The tiny beads inside a softener that catch the minerals that cause scale.
