200TPD Seawater Desalination System with 98% Desalination Rate and 75 kW

Manufactured by Howann, the 200TPD Industrial RO Seawater Desalination System is engineered to meet the critical freshwater demands of coastal cities, island communities, offshore drilling platforms, and marine shipping fleets facing severe natural water scarcity. Designed to process high-salinity raw seawater with a Total Dissolved Solids (TDS) level under 40,000 mg/L, this heavy-duty plant delivers a continuous output of 200 tons of fresh water per day, completely eliminating dependency on unpredictable rainfall or expensive freshwater barging.

Constructed upon a heavy-gauge, corrosion-resistant structural steel frame, the Howann desalination station integrates multi-stage pre-treatment (quartz sand filtration, scale inhibitor dosing, and reducing agent injection for chlorine removal), 8-inch high-rejection RO membrane assemblies, and an intelligent automated PLC control panel. By overcoming high osmotic pressure through powerful 3–5.5 MPa high-pressure pumping, the system effectively strips out 98% of dissolved salts, heavy metal ions, bacteria, and micro-pollutants, ensuring effluent quality that strictly complies with international drinking water standards.

• High-Yield 200 Tons/Day Output: Engineered to provide a stable, uninterrupted daily supply of 200T of fresh water for medium-to-large coastal communities and industrial facilities.
• Outstanding 98% Desalination Rate: Advanced reverse osmosis membrane technology removes up to 98% of dissolved sodium, chloride, and mineral ions in a single pass.
• Robust 75 kW High-Pressure Architecture: High-torque industrial pumps generate the 3–5.5 MPa pressure necessary to overcome natural seawater osmotic resistance.
• Intelligent PLC Automation: Automated control system manages raw water boosting, anti-scalant dosing, membrane flushing cycles, and system safety cut-offs.
• Comprehensive Pre-Treatment Safeguards: Quartz sand filters, reducing agent dosing, and precision cartridge filters protect sensitive RO membranes from suspended solids and chlorine fouling.

• Raw Water Boosting: The raw water pump draws in seawater, providing stable initial pressure to feed the multi-medium filtration train.
• Quartz Sand & Chemical Pre-Treatment: Water passes through quartz sand beds to trap turbidity, followed by scale inhibitors and reducing agents to neutralize residual chlorine and prevent mineral scaling.
• Precision & High-Pressure Filtration: Fine 5-micron security filters remove micro-particles before the 75 kW high-pressure pump elevates water pressure to 3–5.5 MPa.
• RO Seawater Separation: High-pressure seawater forces water molecules through 8-inch semipermeable RO membranes, separating pure fresh water from concentrated brine.
• Ultraviolet Sterilization & Delivery: Purified water undergoes UV disinfection to eliminate remaining microorganisms before entering storage tanks for distribution.

• Coastal Municipalities & Island Communities: Centralized municipal drinking water plants converting ocean water into safe public tap water.
• Seaside Resorts & Tourism Hubs: Independent freshwater generation for hotels, villas, and commercial hospitality complexes on remote islands.
• Marine Shipping & Offshore Rigs: Reliable freshwater provisioning for cargo ships, cruise liners, and offshore oil platforms.
• Seawater-Cooled Power & Industrial Plants: Producing high-purity process and cooling makeup water for thermal and nuclear power stations located near the coast.

• Containerized Mobile Enclosures: Fully pre-assembled ISO shipping container housing (20ft or 40ft) for rapid plug-and-play deployment in remote coastal areas.
• Energy Recovery Devices (ERD): Optional turbochargers or pressure exchangers to slash electrical energy consumption by up to 40%.
• Solar & Hybrid Power Integration: Off-grid photovoltaic solar arrays designed to power auxiliary pumps in remote island locations.
