Automatic Sea Water Purification System with Reverse Osmosis Membranes for Coastal Fresh Water Supply
240TPD SWRO System | Large Seawater Desalination Plant for Industrial & Municipal Freshwater Supply
Introduction
A 240TPD SWRO System is a large-capacity seawater reverse osmosis desalination solution designed to produce approximately 240 tons of freshwater per day from seawater sources. The large seawater desalination plant is widely used in island water supply projects, coastal industrial zones, offshore infrastructure, tourism developments, mining operations, government water projects, marine engineering facilities, and remote coastal communities requiring continuous high-volume freshwater production.
By integrating advanced seawater pretreatment systems, energy-saving high-pressure pumps, SWRO membrane technology, intelligent PLC automation, and modular skid-mounted or containerized structures, the 240TPD seawater desalination system provides reliable freshwater production with stable operation and optimized energy efficiency.
What Is This 240TPD SWRO System?
A 240TPD SWRO System is a large-scale seawater desalination unit engineered to convert seawater into usable freshwater through advanced seawater reverse osmosis membrane technology.
The system removes dissolved salts, suspended solids, marine contaminants, microorganisms, algae, organic matter, and impurities from seawater to produce fresh water for municipal supply, industrial utility water, island drinking water systems, resort freshwater production, offshore accommodation facilities, marine engineering operations, mining camp water supply, and emergency water infrastructure.
The 240TPD seawater desalination system generally includes seawater intake system, raw water transfer pump, multi-media filtration system, activated carbon filter, chemical dosing system, cartridge filter, high-pressure pump, SWRO membrane pressure vessels, energy recovery device, PLC control cabinet, online conductivity monitoring, freshwater tank, UV sterilization system, and containerized or skid-mounted structure.
This large seawater desalination plant is designed for stable desalination efficiency, reliable operation, and long-term durability under marine environmental conditions.
