How do I know what the water hardness is in my area?
Although tap water looks clean it actually contains a lot of dissolved chemicals and minerals. The amount will vary from area to area (Hard & Soft water regions). It is these minerals (mainly calcium and magnesium) that leave white residues on glass.The type of Pure Water System that you will require is dependant on the area in which you fill the machine with water from the mains pipe. From the map below you can determine the water hardness of the area you live in. Then you can select wether you need a DI (De-Ionised) or RO (Reverse Osmosis) Pure Water Fed Pole System.
So, DI or RO. De-Ionised or Reverse Osmosis?
Both machines have Pros and Cons but generally the DI machine is used in Soft or low use Hard Water areas. The RO machine is used in Moderately Hard to very Hard Water areas.
These machines are designed to turn tap water in a Soft Water area into de-ionised water which is used to clean glass. The DI machine uses a special extracting resin to remove 100% of the minerals, which becomes de-ionised water.
PROS CONS Quick filling Cost of resin high in hard water areas Cheaper machines Best for soft water areas or low use hard water areas Simpler
RO (Reverse Osmosis)
The RO machine is designed to be used in a Hard Water area and extracts 95% of all minerals before the water passes through the resin as in the DI, leaving 100% Pure water in you tank. PROS CONS Resin costs as low as 5% of the DI machine Slower filling More expensive
“Select the right products for your business” What type and size of Pure Water Machine will I require?
Ok, so you have identified what type of machine you will need based on the water hardness in the area where you live. You then need to work out what size of a tank you will require and how many operators will be working the system. The systems we supply come in a variety of sizes and can be operated by one or two persons.
