Scale Deposits

Scale deposits are a typical indicator of hard water

Scale deposits from hardness buildup affects fixtures and appliances found throughout the entire home or business - for this reason, hardness is typically addressed with treatment of water for the whole house or building rather than just at a specific faucet

The Water Quality Association (WQA)

Hard water (or water hardness) is a common quality of water which contains dissolved compounds of calcium and magnesium and, sometimes, other divalent and trivalent metallic elements. 

The term hardness was originally applied to waters that were hard to wash in, referring to the soap wasting properties of hard water.

Hardness prevents soap from lathering by causing the development of an insoluble curdy precipitate in the water; hardness typically causes the buildup of hardness scale (such as seen in cooking pans).

Dissolved calcium and magnesium salts are primarily responsible for most scaling in pipes and water heaters and cause numerous problems in laundry, kitchen, and bath.

Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent.

What is Soft Water?

Soft water is defined by American National Standards NSF/ANSI 44 and NSF/ANSI 330 as water containing <1 grain of hardness per gallon (or <17.1 mg/L hardness).

Symptoms of Hard Water include:

·         Stiff, dingy laundry

·         Mineral deposits on dishes and glassware 

·         High soap usage & need for fabric softeners 

·         Extra work to remove soap curd on bathtubs & shower stalls 

·         High energy costs, possibly due to scale build-up in pipes and on appliances

·         Scale build up in sinks, tubs, faucets & appliances

Water treatment can improve hardness issues.

Scale deposits from hardness buildup affects fixtures and appliances found throughout the entire home or business.

For this reason, hardness is typically addressed with treatment of water for the whole house or building rather than just at a specific faucet.

Hardness minerals can be reduced in water for the whole house to make it “softer” by using one of the following means:

·         Chemical softening — lime softening, hot and cold; lime-soda softening

·         Membrane separation softening — Nano filtration

·         Cation exchange softening — inorganic, carbonaceous, or organic base exchangers

The Water Quality Association (WQA) is a not-for-profit association for the residential commercial, and industrial water treatment industry. WQA represents more than 2,500 member companies around the globe. Our membership is comprised of equipment manufacturers, suppliers, dealers and distributors of water quality improvement products and services. 

WQA proudly serves as an educator of water treatment professionals, certifier of water treatment products, public information resource and voice of the water quality improvement industry.
