What is Water Pretreatment?

Water pretreatment removes suspended impurities, solids, colloids and living organisms from raw water. Water pretreatment processes ensure that your water quality is not influenced by seasonal changes, extreme weather or industrial pollution. Conventional water pretreatment refers to the processes applied to the treatment of water or wastewater prior to feeding a membrane separation process (MSP).

Water Pretreatment Technologies

Our water treatment technologies have been developed by technical, industry experts who ensure that these versatile systems meet increasingly stringent demands. Flocculation and coagulation processes are typically used in water pretreatment in order to remove particles which cannot be removed by sedimentation or filtration. Filtration, ultrafiltration, microfiltration and nanofiltration processes along with reverse osmosis are used to filter out various sizes of particles along with ions, allowing purified water to flow through.

Water Pretreatment Benefits

Here are some of the key benefits provided by water pretreatment:

  • Extends the life of subsequent reverse osmosis (RO) plant membranes
  • Ensures that the water delivered to the RO or EDI (electrodeionisation) system meets the required quality standard
  • Supports the delivery of a continuous and dependable water supply
  • Maximises the overall water processing plant lifecycle, thus reducing costs
