Multi-media water filter systems are ideally suited for use where stringent water quality standards are required or where higher levels of suspended solids are present. These applications can include re-use applications, water pre-treatment applications for reverse osmosis and deionization systems or as a pre-treatment system prior to disposable bag or cartridge filters.

What Is Water Softening?
Water softening is a key step in treating hard or raw water. Without this step, minerals and materials in raw water such as calcium, magnesium and various others can build up to damage the water treatment equipment; specifically the membranes used to clean water. Removal of these materials can be achieved by ion exchange.

What Is UV Sterilization?
In the world of water purification and treatment, having an Ultraviolet or UV sterilizer can make your water healthier and prolong the life of water that has been treated and processed. What a UV sterilizer does is it further cleans the water and kills any of those nasty little bacteria and microorganisms that can still infest water even after it has been treated.

What Is Sea Water Desalination?
The Desalination industry is relatively small; however it is a growing market. While water is plentiful, over 97% is too salty for human consumption. Desalination companies utilize the unlimited supply of seawater and through Reverse Osmosis or distillation, create potable water by removing the salts.

What Is RO Antiscalant?
Antiscalant chemicals are used to prevent the scaling & fouling of the RO membranes. Scale may consist of mineral fouling such as calcium sulfate, calcium carbonate, barium sulfate, silica, calcium fluoride, and strontium sulfate. The Antiscalant dosing should be done before reaching the RO membranes to break up sulfate precipitates, calcium carbonate, and other mineral fouling.

2.1 billion people lack safe drinking water
12 JULY 2017 | GENEVA | NEW YORK – Some 3 in 10 people worldwide, or 2.1 billion, lack access to safe, readily available water at home, and 6 in 10, or 4.5 billion, lack safely managed sanitation, according to a new report by WHO and UNICEF.

WHO Drinking water quality guidelines
WHO produces international norms on water quality and human health in the form of guidelines that are used as the basis for regulation and standard setting world-wide.
The Guidelines for drinking-water quality (GDWQ) promote the protection of public health by advocating for the development of locally relevant standards and regulations (health based targets), adoption of preventive risk management approaches covering catchment to consumer (Water Safety Plans) and independent surveillance to ensure that Water Safety Plans are being implemented and effective and that national standards are being met.
Reverse Osmosis and Removal of Minerals from Drinking Water
Reverse Osmosis will generally remove salt, manganese, iron, flouride, lead, and calcium (Binnie et. al., 2002). Most mineral constituents of water are physically larger than water molecules and they are trapped by the semi-permeable membrane and removed from drinking water when filtered through a RO (AllAboutWater.org, 2004). Meanwhile, consumers are concerned about the removal of minerals from their drinking water.
