Salt Water Softener

Supplier From Pyramids, Giza, Egypt
Product name: Salt Water Softener
HS Code: 250100
Packing: 25,50 kg bags

When we talk about â??hard water,â?? weâ??re not talking about ice. Weâ??re talking about water that contains high amounts of minerals like calcium and magnesium. Hard water isnâ??t harmful, but it has plenty of bothersome side effects, including:

Impact water taste
Dry out skin
Leave residue in hair
Clog up your pipes
Affect your water's ability to lather in the shower, sink, washing machine and other devices
A water softener is the only way to remove minerals from your water and prevent problems like these. After the water softener has been used over and over again, the filter needs to be recharged with more salt to continue working effectively.

When you need to put your water softener through a regeneration cycle, youâ??ll need water softener salt, or sodium chloride. You can only use salt that is designed for water softeners, not table salt or deicing salt. Water softener salt is specially designed to work for your water softener and make it efficient.

Water softener salt comes in forms like crystals, blocks or pellets, which enable more effective regeneration. You already know you need salt for your system, but did you know not all salt is created equal? The right type of salt can help your water softener perform better and prevent damage to your appliances and water softening system. Hereâ??s a look at various types of water softener salt and what to consider with each one.
