Water Filtration Systems
Filtration removes suspended solids from water. Various types of water filtration systems are available, with selection depending on the raw water make up (particle size and distribution) and quality requirements of the product water.
Filtration is commonly used as ‘pre-treatment’ of raw water, to remove suspended solids, prior to desalination via Reverse Osmosis (RO). Typical RO pre-treatment systems include Micro Filtration (MF), Ultra Filtration (UF) and Multi-Media and Cartridge Filtration.
Other forms of filtration are used to remove excess ‘hardness’ (generally calcium & magnesium) which have the potential to cause scaling of plumbing and other undesired effects. Typical softening processes involve Ion Exchange, whereby calcium and magnesium ions are replaced with sodium ions, or Nano Filtration (NF).
