50,000 GPD Seawater Reverse Osmosis System with 1,200 PSI and Duplex SS 2205

Manufactured by Howann, the 50,000 GPD Industrial Seawater Reverse Osmosis System is engineered to meet the extreme freshwater demands of coastal cities, island communities, marine shipping fleets, and offshore energy platforms facing severe water scarcity. Designed to process raw ocean water with Total Dissolved Solids (TDS) reaching up to 50,000 ppm, this commercial plant delivers a dependable, continuous output of 50,000 gallons (190 cubic meters) of purified fresh water per day.

Because marine environments are notoriously corrosive due to aggressive chloride ions, the Howann desalination station utilizes premium metallurgy—including Duplex Stainless Steel 2205 and high-grade FRP pressure vessels—to prevent pitting and stress corrosion cracking. Integrated with high-capacity 8-inch seawater RO membranes, precision pre-treatment filtration, and an intelligent PLC control architecture, the system effortlessly overcomes natural osmotic pressure to strip out 99% of dissolved mineral salts and biological pathogens.

• High-Yield 50,000 GPD (190 m³/Day) Output: Engineered to provide an abundant, uninterrupted daily supply of fresh potable water for mid-to-large coastal enterprises and communities.
• Aggressive 1,200 PSI High-Pressure Pumping: Robust industrial booster pumps generate the extreme hydraulic pressure required to force water molecules through semi-permeable membranes against natural seawater osmotic drag.
• Duplex SS 2205 Corrosion Resistance: Specialized marine-grade stainless steel and super-duplex alloys prevent premature pitting and structural failure caused by high chloride concentrations.
• Outstanding 99% Salt Rejection: Advanced thin-film composite membranes separate pure water from concentrated brine, which is safely flushed back into the ocean.
• Intelligent PLC Automation: Automated control system manages raw feed boosting, chemical scale inhibitor dosing, and automated membrane rinsing cycles to minimize manual oversight.

• Raw Seawater Intake & Pre-Treatment: Ocean water is drawn through deep-sea intake wells or open-sea screens, passing through multi-media quartz sand and carbon filters to remove suspended solids, turbidity, and algae.
• Scale Inhibitor Dosing: Anti-scalant chemicals are automatically injected to prevent calcium carbonate and sulfate scaling on the membrane surfaces.
• High-Pressure RO Separation: The 1,200 PSI industrial pump pressurizes the pre-treated water through 8-inch seawater RO modules, splitting the stream into pure permeate and concentrated brine.
• Post-Treatment & Distribution: Purified fresh water is routed to storage reservoirs, where pH balancing and disinfection prepare it for safe human consumption or industrial processes.

• Coastal Municipalities & Island Resorts: Decentralized municipal drinking water plants converting ocean water into safe public tap water for island hotels and townships.
• Offshore Drilling & Marine Vessels: Reliable freshwater provisioning for cargo ships, luxury yachts, and offshore oil exploration platforms.
• Industrial Coastal Manufacturing: High-purity process and cooling water supply for seaside power stations, refineries, and chemical plants.
• Agricultural Irrigation in Arid Coasts: Desalinated water supply for specialized coastal farming and greenhouse hydroponic systems.

• Energy Recovery Devices (ERD): Optional pressure exchangers or turbochargers to recover hydraulic energy from high-pressure brine waste, slashing electrical power consumption by up to 40%.
• Containerized Mobile Enclosures: Fully pre-assembled 20-foot or 40-foot ISO shipping containers equipped with air conditioning, lighting, and internal plumbing for plug-and-play field deployment.
• Solar & Hybrid Power Integration: Off-grid photovoltaic arrays designed to power auxiliary booster stages in remote locations.
