Technical Specification Overview 

Size: 8-inch diameter 

Effective membrane area: Approximately 440 square feet (about 41 square meters) 

Water production under standard test conditions: approximately 12,000 gallons per day (about 45.4 cubic meters per day). It should be noted that the actual water production may vary depending on factors such as the TDS (total dissolved solids) of the incoming water, temperature, operating pressure, and recovery rate. 

Maximum operating temperature: 45°C 

pH range (continuous operation): 2 - 11; under chemical cleaning conditions, the pH range is 1 - 12. 

Desalination rate: Generally, the desalination rate can reach over 99%. The specific value depends on the actual application conditions such as the quality of the incoming water. 

Operating pressure: Due to its design for extremely low energy consumption applications, it can operate at relatively low pressure, which helps to reduce energy consumption.
