Residential Water Treatment:
Terms & Definitions

Water Quality and Composition

Water Hardness: A measure of the amount of calcium and magnesium in the water. Hard water can cause scale buildup in pipes and appliances.

Mineral Content: The amount of minerals, such as calcium, magnesium, and iron, present in the water.

Total Dissolved Solids (TDS): The total amount of minerals, salts, metals, and other particles dissolved in water.

Water Conductivity: How well water can conduct electricity, which depends on the amount of dissolved salts and minerals in it.

pH Balance: A measure of how acidic or basic the water is on a scale from 0 to 14, with 7 being neutral.

Contaminant Removal: The process of eliminating harmful substances from the water to make it safe to drink.

Water System Issues

Scale & Limescale: Hard, chalky deposits that form on pipes and appliances due to hard water.

Corrosion: The gradual destruction of materials (usually metal) by chemical reactions with the environment, often leading to rust.

Buildup: The accumulation of minerals, scale, or other materials inside pipes and appliances over time.

Biofilm: A thin, slimy layer of bacteria that can form on the surfaces of pipes and water systems.

Biofouling: The unwanted buildup of microorganisms, plants, algae, or small animals on wet surfaces, especially underwater surfaces.

Chlorine: A chemical commonly added to water to kill harmful bacteria and other microbes.

Bacteriostatic: A property of some substances that stops bacteria from reproducing, helping to control bacterial growth.

Water Treatment Processes

Flocculation: A process where chemicals are added to water to make small particles stick together into larger clumps so they can be easily removed.

Activated Carbon: A material used in water filters to remove contaminants and impurities through chemical absorption.

Reverse Osmosis: A method of purifying water by pushing it through a special membrane that removes larger particles and contaminants.

Sediment Filter: A type of filter that removes particles like dirt and sand from water.

Water Softener: A system that removes minerals that cause water hardness, usually by using salt.
