10 Ton/Day Two-Stage Seawater Desalination Unit

10 Ton/Day Two-Stage Seawater Desalination Unit
Product Introduction

I. Product Overview

This unit is an integrated, two-stage reverse osmosis seawater desalination system with a daily pure water output of 10 tons. It employs a dual-stage purification process—combining primary coarse desalination with secondary fine desalination—to deliver water purity far superior to that of standard single-stage systems. Featuring an ultra-compact, integrated skid-mounted design, the unit offers a minimal footprint, simple installation, low energy consumption, and fully automated operation. It is custom-engineered for fishing vessels, yachts, island cabins, coastal construction sites, small outposts, and compact overseas projects; its key advantages are its space-saving design, high-purity output, and low power consumption.

III. Process Principles (Core Advantages of Two-Stage Design)

1. First-Stage Seawater Reverse Osmosis
Performs initial deep desalination of seawater, rejecting the vast majority of salts, sediment, colloids, and microorganisms. The output water quality is stably maintained below 500 ppm, making it suitable for general domestic use and cleaning purposes. 2. Second-Stage Precision Reverse Osmosis Purification
The permeate from the first stage undergoes further deep filtration and desalination to remove residual trace salts and metal ions. The final output consistently maintains a level of ≤10 ppm, meeting high-purity water standards suitable for direct consumption, high-standard domestic use, and equipment feed water.

This dual-stage stacked process overcomes the common drawbacks of standard seawater treatment systems—such as salty-tasting output, poor water quality, and unsuitability for direct drinking—enabling even compact units to achieve ultra-high water purity. IV. Equipment Configuration Highlights

- Ultra-compact integrated design: A tiny 1.6-meter footprint; requires no infrastructure and fits into corners—ideal for space-constrained environments.
- Low power consumption: Total system power is only 7 kW, ensuring low electricity costs for continuous or intermittent 24-hour operation.
- Dual-stage precision desalination: Produces both domestic-grade water (Stage 1) and purified water (Stage 2); dual-purpose functionality allows for water selection based on needs.
- Fully automated, unattended operation: Automatically starts water production and flushes membrane elements upon shutdown to prevent scaling and membrane fouling.
- Corrosion-resistant configuration: Designed specifically for high-salinity marine environments; features corrosion-resistant pump bodies, piping, and a stainless steel frame for a long service life.
- Real-time water quality display: Dual-channel conductivity monitoring with independent displays for Stage 1 and Stage 2 water quality, making quality visible at a glance.

V. Output Water Quality Standards

- Stage 1 Output: ≤500 ppm
Meets standards for daily washing, vegetable cleaning, and general domestic use.
- Stage 2 Output: ≤10 ppm
High-purity desalinated water; tastes sweet with no salty aftertaste; meets the standard for direct-drinking purified water.

VI. Applicable Scenarios

- Island guesthouses, small island campsites, and offshore aquaculture platforms.
- Domestic water supply for fishing vessels, yachts, and offshore workboats.
- Small coastal construction sites, temporary project offices, and border defense outposts.
- Small-scale overseas desalination projects and island water supply initiatives in Southeast Asia.
- Water purification upgrades in areas with high-salinity or brackish water.

VII. Product Advantages Summary

1. Smallest footprint: Most compact dimensions on the market for this output capacity; saves space and facilitates easy transport.
2. Superior water quality: Dual-stage process produces ultra-pure water (10 ppm), far exceeding the performance of standard seawater equipment.
3. Lower energy consumption: Low total power of 7 kW results in minimal operating and maintenance costs.
4. Simplest operation: Fully automated, "plug-and-play" style operation; requires no professional personnel on-site.
5. High adaptability: Compatible with both seawater and brackish water; highly resistant to fouling and salt spray.
