PTFE Lined Pipes in the Water Treatment Industry

On average, a human uses a whopping amount of around 80-100 gallons (302- 378 litres) of water daily. Once water has been used, it must be treated before releasing back into the environment. Hence, the water treatment industry is one of the most important industries in the world which not only keeps the environment clean, but also providing us with clean drinking water. Ensuring the effectiveness and usability of piping systems in water treatment plants is important in maintaining constant supply of fresh and clean water.

During the water treatment process, different types of chemicals are used to neutralise the pH of wastewater, such as Ferric Chloride, Urea, Phosphoric Acid etc. These chemicals are highly corrosive and would require the piping systems to be changed once every few years. In such cases, PTFE/PFA Lined Pipes would be a better choice as PTFE and PFA are corrosion resistant. Here are a few benefits of using PTFE/PFA lined pipes when such chemicals are used:

Extended time between maintenance and rebuilds

Maintenance of treatment plants are necessary, but time between rebuilds can be increased when PTFE/PFA lined pipes are used. Being a corrosion resistant material, it ensures the longevity of piping systems when in contact with highly corrosive chemicals. The impact of downtime in the water treatment industry may result in tremendous cost.

Increases efficiency

Increasing efficiency is important for every chemical plant, and the low friction coefficient of PTFE and PFA allows chemicals and substances to pass through more smoothly. This in turns reduces the buildup of sludge and unwanted sediments that could potentially cause minor blockages in piping systems.

ALMARC Engineering strives to manufacture and produce the best PTFE/PFA Lined Systems for the water treatment industry. We have a wide range of product selection to fit your needs:

Piping Systems, Hoses and Fittings

We have a range of PTFE, PFA and PP lined piping systems with sizes ranging from 1/2″ to 12″ for pipes, and 1/4″ to 6″ for hoses, depending on the size required.
