Using CPVC for Reverse Osmosis in the Desalination Plant

Desalination is experiencing a rapid rise in popularity worldwide, as populations continue to soar. The plant activity has particularly stepped up in coastal regions, the Middle East being among the most prominent.

Running a Desalination plant is a highly hazardous and toxic process, particularly using traditional, thermal methods. Reverse osmosis has emerged as the cost effective, efficient alternative to thermal desalination; here's why.

  • Membrane technology allows desalination at lower pressures
  • Reverse osmosis requires less energy than thermal
  • Cost effectiveness allows desalination plant activity in more regions than ever before

Running a seawater desalination plant is always going to be an energy intensive and expensive process. However, with the ongoing improvement of water distribution technology, such as Corzan CPVC pipes and fittings, reverse osmosis is becoming even more accessible.

Why Reverse Osmosis for desalination plants?

Reverse osmosis removes salt and other impurities from water, drawn from the sea. A semipermeable membrane allows only water molecules to pass through, while the salt and other impurities including various pathogens are rejected. The result is fresh water, plus a highly saline residual solution, or brine.

As membrane technology improves, so too does the efficiency of reverse osmosis. Here in 2022, reverse osmosis desalination plants are producing a healthier balance of fresh water to brine than ever before.

However, in Saudi Arabia and across the Middle East, thermal desalination plant technology has been relied upon a great deal until the recent past, and with a high concentration of seawater desalination plant activity taking place, these traditional plants are having a significant effect on the environment as the challenge of producing adequate fresh water continues.

Distributing water for the future of the planet

So how can the desalination plant industry move towards better efficiency and smarter cost management in the future? It is not only our water supply that depends on it; it also has a deep effect on the climate.

Let's look at what takes place before the membrane technology comes into play. If highly corrosive sea water for the plant is distributed the most efficient way, it could mean even lower running costs and even greater efficiency.

Why CPVC for Reverse Osmosis desalination?

Efficient desalination plant construction

Corzan CPVC is a more efficient and straightforward material to assemble and install than its metallic counterparts. It is also lighter, despite its industry leading strength and pressure bearing capabilities. Extrusion into smaller sizes allows for smarter use of space and a reduction in costs to the overall facility.

In recent times, it has become necessary to construct temporary desalination plants globally. in this climate, where water crises are prevalent, time efficiency is a life saving factor.

Reliable high pressure water distribution

Corzan CPVC has several advantages over other materials in the processing of highly corrosive, hazardous substances. Its durability and chemical resistance is critical to the high demand of a typical desalination plant in a coastal environment. Corzan CPVC can process water from the sea and distribute it to the osmosis membranes without the threat of corrosion, scaling, chemical leaching or UV degradation.

Access better desalination today

The trend for desalination is definitely towards smaller and more efficient plants, which is good news for coastal communities and industries that are struggling with water shortages. As technology improves, the cost of reverse osmosis will continue to drop, making this process an increasingly viable option for those looking to address their water needs.
