Home Water Treatment for Scale Inhibition

Scale deposition is an indicator of hard water. Hardness of water is defined as the amount of dissolved calcium and magnesium in the water. Hard water is water with high hardness that contains very high amounts of calcium and magnesium. Groundwater typically has higher hardness as compared to surface water sources mainly because as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply. One of the effects of hard water is the inability to form soap lather. In the presence of hard-water the soap reacts with calcium and magnesium to form soap scum. This can result in using more soap or detergent to clean things that could be hair, laundry, or dishes. Using hard water can cause stains on dishes and silverware. More importantly, hard water can leave residue/ scale deposits of calcium carbonate in home appliances such as hot water heaters, coffee makers, etc. and subsequently cause an increase in maintenance cost or reduce life of the equipment. Hard water can also clog household plumbing networks due to calcium-carbonate scale buildup. 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

Scale inhibitor water treatment systems provide an effective solution to these issues.

Residential water-heaters and several other home appliances can be severely affected by the characteristics of water supplied to these appliances. Use of hard water containing high contents of calcium and magnesium can cause scale buildup and corrosion of the plumbing network decreasing the lifespan of the appliances and increasing maintenance cost. The 3M™ High Flow Series Replacement Cartridge, Model HF8-S Scale Inhibition Water Treatment System provides a great solution to all the issues caused due to scale buildup from hard water.
