INDUSTRIAL RO PROJECT CASE STUDY
5,000 LPH Industrial Reverse Osmosis Systems for Boiler Projects
This industrial RO system for boiler water was supplied for an Australian industrial plant. Rated at 5,000 LPH, the system treats groundwater with a feed-water TDS of 986 ppm and produces purified water for stable boiler supply.

Project Overview
Start with the customer's real production requirement
This case study is based on a 5000 liters/hour reverse osmosis project in operation in Australia. The system was configured according to the client’s production requirements, a feed water TDS value of 986 ppm, and the plant’s 380V/50Hz three-phase four-wire power supply.
Customer Requirement
For use in factory boiler supply
Rated product water treatment capacity: 100 tons/day
Daily operation: 20 hours
Electrical design compatible with Australian factory power systems
Roller-mount design for easy relocation
Easy maintenance and simple consumable replacement
Engineering Focus
The total dissolved solids (TDS) content of the influent alone is insufficient to determine a complete treatment solution. When determining pretreatment, recovery, and membrane configuration, hardness, alkalinity, silica, iron, chlorine, microbial status, and the required final water quality standards should also be considered.
Furthermore, a comprehensive evaluation is necessary, incorporating existing water quality testing information, as well as factors such as water color and taste.

Treatment Process
Treatment Logic for 986 ppm Feed Water
The RO section is designed around the complete water chemistry, required product-water quality, operating hours and production demand—not TDS alone.
Pretreatment
Based on the complete feed water analysis results, a suitable process was selected to protect the reverse osmosis membrane. The final configuration included quartz sand filtration and activated carbon adsorption for pretreatment of the client's water.
Activated carbon: Reduces discoloration and odor in water, as well as some metal ions.
Fine Filtration
Reduce particulate load before the high-pressure pump and membrane section. The selection of filter cartridge ratings and housing sizes is designed to protect downstream equipment. Furthermore, an antiscalant system is added to reduce the risk of membrane fouling.
Reverse Osmosis
This method can reduce dissolved salt content, etc., and is ultimately used for the plant water required for boilers. Five VONTRON ULP-8040 series membranes are arranged in series.
For medium and large-scale reverse osmosis systems, 8040 membranes will be used compared to 4040 reverse osmosis membranes. 8040 membranes have a larger water treatment capacity per unit and can reduce the number of membranes required.
Storage / Supply
Balances production demand and supplies the downstream jam-production process. Tank volume, material, level control and distribution pressure are selected for the operating schedule.
System Configuration
What the 5,000 LPH System Should Document
In this project, the core component brands and materials used in the reverse osmosis system
01
Raw Water Pump
A SHIMAGE brand stainless steel centrifugal pump is used. The appropriate influent flow rate is matched to the required throughput of the RO system. Here, a 10 cubic meter per hour pump is used.
02
Pretreatment System
The quartz sand and activated carbon filtration system effectively reduces water turbidity and removes unpleasant colors and odors.
03
Placed before the precision filter, the scale inhibitor reduces the risk of rapid fouling of the downstream membrane module.
04
Cartridge Filter
Equipped with a 40-inch 5-micron precision PP cotton filter element and a stainless steel filter housing.
05
High-Pressure Pump
A SHIMAGE brand reverse osmosis pump is used, matched to the 5,000 L/h permeate requirement and the calculated RO operating pressure.
06
RO Membranes
Choose the VONTRON 8040 ULP series module, which is equipped with 5 RO membrane modules in a series configuration.
07
Product-Water Tank
Select appropriate capacity and materials based on peak production periods and hygiene requirements. (Customer prepares these materials themselves.)
08
Control & Monitoring
Equipped with an automatic control valve, it enables automatic flushing and monitoring and alarm functions for conductivity, pressure, flow rate, and liquid level control.
