I. System Overview
(I) Core Capabilities and Technical Foundation
Centered on reverse osmosis technology—the mainstream technology worldwide—this system is specifically designed for desalinating seawater and brackish water, capable of producing pure freshwater that meets drinking water standards. Its daily production capacity ranges from 60 to 1000 tons (equivalent to 15,000 to 260,000 gallons), which can adapt to diverse water consumption scales, from small communities to large-scale projects.
(II) Core Advantages of Containerized Design
The system adopts a fully integrated container design, integrating four core modules—pretreatment, reverse osmosis (RO), chemical cleaning, and chemical dosing—into a standardized container. The advantages are remarkable:
