Chemical cleaning, commonly known as Clean-in-Place (CIP), is an important maintenance procedure for seawater reverse osmosis (SWRO) systems when membrane performance declines due to fouling, scaling, or other deposits. Knowing when to clean is just as important as knowing how to clean. Operators typically evaluate changes in normalized permeate flow, salt passage, feed pressure, differential pressure, and other operating data before initiating CIP. A suitable cleaning sequence, compatible chemicals, controlled temperature and pH, adequate circulation, and proper rinsing can help restore membrane performance while reducing unnecessary cleaning frequency and membrane damage.

Concentration polarization is an important transport phenomenon in seawater reverse osmosis (SWRO). As water passes through the RO membrane, salts and other rejected substances can become more concentrated near the membrane surface than in the bulk feedwater. This concentration boundary layer increases local osmotic pressure and can reduce the effective driving force for water transport. This article explains how concentration polarization develops, how feed flow, membrane flux, salinity, recovery, and spacer design influence the phenomenon, and why proper pretreatment and operating control are important for maintaining stable SWRO membrane performance.

Offshore oil platforms and supply vessels require reliable freshwater sources for crew living, equipment operation, drilling support, cleaning, and daily industrial activities. Because these facilities are located far from shore, transporting freshwater by ship can increase operating costs and create supply risks. SWRO seawater desalination systems provide a practical solution by converting surrounding seawater into freshwater directly offshore.
This article explains how SWRO systems are designed for offshore applications, including platform space limitations, seawater intake, pretreatment, high-pressure RO operation, corrosion-resistant materials, energy supply, automation, maintenance, and integration with offshore facilities. It also discusses containerized and skid-mounted desalination units for offshore oil platforms, FPSO vessels, and marine support vessels.

Brine is the concentrated stream remaining after water is separated from seawater or industrial wastewater during desalination. How this stream is handled can affect energy consumption, environmental management, operating cost, and the overall design of a water treatment project. Conventional brine discharge may use controlled marine outfalls where site conditions and regulations permit. Zero Liquid Discharge (ZLD) takes a different approach by further concentrating the liquid stream and recovering water while minimizing or eliminating liquid discharge. Mineral recovery can go one step further by selectively recovering useful salts or minerals from concentrated brine. The appropriate strategy depends on feedwater chemistry, recovery targets, site conditions, discharge requirements, energy availability, and the potential value of recovered materials.

Seawater desalination equipment operates in an environment where high chloride concentration, dissolved oxygen, temperature changes, pressure, and chemical exposure can accelerate corrosion. Material selection therefore has a direct influence on equipment service life, maintenance requirements, leakage risk, and long-term operating stability. Stainless steels, duplex stainless steels, super duplex stainless steels, nickel-based alloys, titanium, FRP, and selected engineering plastics may all be used in different parts of a desalination system. The appropriate material depends on seawater quality, pressure, temperature, chemical conditions, component function, fabrication requirements, and project budget. Understanding where each material is suitable helps engineers design more reliable seawater desalination equipment.
