Prefiltration is crucial
Desalination by Reverse Osmosis (RO) has been a reliable technology for over 20 years. Ensuring the correct performance of these systems requires a thorough evaluation of the influent water quality. It's essential to propose the most suitable prefiltration method that aligns with the client's space, temperature, and financial conditions.
At Norwegian Greentech, we take pride in our expertise in prefiltration and offer comprehensive solutions to our customers. Our knowledge and experience enable us to tailor our systems to meet the specific needs of each client, ensuring optimal performance and efficiency.
Maintaining clean seawater is crucial for optimising the performance and extending the lifespan of RO membranes upstream of the filtration unit. A well-engineered system is essential to minimise troubleshooting and ensure efficient operation.
Prefiltration systems effectively remove larger particles and debris, safeguarding the RO membranes.
