What Is This Automatic Seawater Purifier?

An Automatic Watermaker is a fully automatic seawater desalination system that uses reverse osmosis membrane technology to remove salt, dissolved minerals, bacteria, algae, and impurities from seawater.

Unlike conventional manual desalination equipment, the automatic seawater purifier integrates intelligent control systems to automatically manage system operation, pressure adjustment, flushing procedures, alarms, and freshwater production.

A complete automatic watermaker system generally includes seawater intake system, raw water feed pump, pretreatment filtration system, cartridge filtration, automatic chemical dosing, high-pressure pump, SWRO membrane system, PLC automatic control cabinet, automatic membrane flushing system, online TDS monitoring, and freshwater storage and distribution.

The automatic control system continuously monitors pressure, conductivity, flow rate, and system performance to maintain stable operation. It can automatically start, stop, flush membranes, monitor alarms, and protect the system from low pressure, high pressure, or abnormal operating conditions.

Technical Specifications

Features & Advantages

1. Fully Automatic Operation

The automatic seawater purifier supports one-button startup, automatic flushing, alarm protection, and intelligent operating control.

2. Stable Freshwater Production

The automatic watermaker continuously produces stable low-TDS freshwater suitable for drinking water and industrial applications.

3. Intelligent PLC Control System

PLC and HMI systems monitor conductivity, pressure, flow, and membrane performance in real time.

4. Automatic Membrane Flushing

The system automatically flushes membranes after operation to reduce fouling and extend membrane service life.

5. Reduced Labor Requirements

Automatic operation minimizes manual intervention and simplifies daily system management.

6. Compact and Space Saving Design

The skid-mounted structure is suitable for yachts, fishing boats, offshore platforms, and compact equipment rooms.

7. Corrosion Resistant Construction

Marine-grade materials including SS316L improve durability under seawater and offshore operating conditions.

8. Energy Efficient Operation

The automatic seawater purification system reduces operating costs through optimized pressure control and energy-efficient process design.
