Description
Features
- Often used in:
- Commercial Applications – Used in hotels, restaurants, and laundries to protect plumbing and equipment.
- Industrial Water Treatment – Helps prevent scale and corrosion in boilers, cooling towers, and heat exchangers.
- Municipal Water Supply – Sometimes added to public water systems to reduce corrosion in distribution pipes.
- Household Water Systems – Prevents scale buildup in pipes, geysers, kettles, and appliances.
- Usage guidelines:
- The standard dosage depends on water hardness and flow rate.
Typical dosing range: 2 – 5 ppm (parts per million) of Siliphos in water.
A common rule is 1 kg of Siliphos can treat approximately 100,000 liters (100 m³) of water.
Replenishment is usually needed every 3 – 6 months, depending on water consumption and hardness. - Siliphos spheres have been shown to offer the following benefits in the treatment of potable and process water systems:
Stabilize the hardness constituents in cold and hot water systems (up to 80ºC)
Prevent precipitation/formation of scale on internal surfaces
Sequester the heavy metal ions e.g. iron & manganese
Minimise the occurrence of red water caused by dissolved iron
Prevent pipe corrosion by forming a protective layer of phosphates
Enable the gradual removal of existing scale - Siliphos is a scale inhibiting or sequestering agent in the form of soluble, sodium hexametaphosphate spheres.
- The formation of scale on surfaces in potable water systems is due to the crystallization of carbonates or sulfates of magnesium or calcium from solution.
- Siliphos works be releasing low levels of polyphosphates into the water which interfere with crystal growth, as well as by forming a protective layer of Iron-Calcium-Phosphates along the inner surfaces of pipes, water tanks, elements etc. which deters the deposition and formation of scale.
- Siliphos is introduced into water systems via a treatment media filter housing that holds the spheres, which are slowly dissolved away as water flows over them.
