Project Overview

This project is equipped with two sets of 50m³/h boiler feed water membrane deoxygenation systems, serving the heating boiler water supply treatment of a local enterprise in Uzbekistan. The system takes RO permeate as inlet water, efficiently removes dissolved oxygen in water through professional membrane deoxygenation technology, and meets the high-standard water supply requirements of heating boilers.

Core Treatment Index

• Inlet Dissolved Oxygen: 7000 ppb (7 ppm)

• Outlet Dissolved Oxygen: 50 ppb

• Oxygen Removal Rate: Up to 99.5%

Inlet Water Quality Conditions

The inlet water is qualified RO produced water with stable water quality, free of strong oxidizing substances, surfactants, organic solvents and other interfering substances. The specific parameters are as follows:

• Water Temperature: 5–40℃

• Surface Tension: ≥65 mN/m

• Suspended Solids (SS): ≤1 ppm

• COD: ≤50 ppm

• Inlet Pressure: ≤0.6 MPa

• ORP: ≤100

• Oil Content: ≤3 mg/L

• Particle Size: ＜4 μm

• Residual Chlorine: ＜1 ppm

System Operation Parameters

• Installed Power: 22 kW

• Operating Power: 10 kW

• Specific Water Energy Consumption: 0.2 kWh/t

Project Advantages

The membrane deoxygenation system features low energy consumption, stable operation and high deoxygenation efficiency. It operates stably within a wide temperature and pressure range, with low failure rate and simple daily maintenance. It effectively avoids boiler corrosion and scaling caused by dissolved oxygen, greatly extending the service life of boiler equipment, and is an efficient and energy-saving solution for heating boiler feed water treatment.
