Ⅲ Tier: Large-Scale Coastal Resort Estate | 100–260 Guest Rooms

(Integrated Island Resort with Beach, Swimming Pool Complex, and Dining Facilities)

Total Daily Water Consumption: 120–220 m³/day

1. Seawater Desalination

Two 40-ft containerized SWRO seawater desalination units operate in parallel, with a combined production capacity of 130 m³/day (5.4 m³/h). The system features a modular skid-mounted design, allowing individual units to be started, stopped, or serviced independently while maintaining continuous water supply.

2. Pretreatment + Whole-Property Water Purification

• Main Pre-Filter: 15 m³/h, DN65 high-flow stainless steel pre-filter

• Multimedia Pretreatment: 12 m³/h

• Central Water Purification: 8 m³/h, dual-tank parallel configuration

• Central Water Softening: 8 m³/h, three-tank intelligent parallel system for 24-hour continuous softened water supply

3. Drinking Water System

Centralized purified water station: 2 m³/h

Purified drinking water is distributed throughout the resort via a centralized water supply network, providing convenient access to treated drinking water for guest rooms and other designated areas.

Ⅱ. Island-Specific Upgrade Options

(Value-added configurations and key selling points for overseas resort projects)

1. Customized Corrosion Protection

The entire system piping can be upgraded to 316 stainless steel, designed for high-salt-spray and high-humidity island environments to improve corrosion resistance and support long-term equipment operation.

2. Smart Control and Remote Monitoring

The complete system is equipped with a PLC + HMI control system, with optional remote Wi-Fi monitoring. Overseas hotel operators can remotely monitor equipment operating status and perform routine system management.

3. Off-Grid Solar-Powered Version

The desalination system can be integrated with a solar photovoltaic power supply package, making it suitable for remote islands and off-grid resort projects without reliable municipal electricity.

4. Water Reuse

Simple reclaimed-water filtration can be configured for suitable sources such as swimming pool water and shower wastewater. Treated reclaimed water can be reused for landscape irrigation and garden watering, helping reduce overall freshwater consumption.
