Industrial Reverse Osmosis Equipment: Custom Pure Water Treatment System Solution

Industrial reverse osmosis equipment serves as core pure water production facility for global manufacturing plants. We supply turnkey RO systems equipped with Dow Filmtec RO membrane, compatible with low energy RO membrane and high rejection membrane elements. Our service covers RO equipment retrofit, system capacity expansion, zero liquid discharge RO concentration system, as well as industrial RO equipment rental. Custom design for industrial pure water stations meets diverse feed water and purification standards across industries.

Product Description

Industrial reverse osmosis equipment is a fully integrated skid-mounted water purification system designed to remove dissolved salts, heavy metals, colloids, microorganisms and organic pollutants from raw water. As the mainstream membrane separation water treatment device for industrial pure water preparation, this set of equipment can be flexibly matched with high rejection RO membrane and low energy RO membrane including  BW30 Series membrane elements according to raw water salinity and production targets. Beyond new system manufacturing, we also provide supporting services including existing RO system capacity expansion, RO equipment retrofit/upgrade, industrial RO equipment rental/leasing, and complete design service for industrial pure water stations. For projects with strict wastewater emission standards, the equipment can be combined with a zero liquid discharge RO concentration system to realize water resource recycling. All units adopt modular layout, support automatic operation and optional RO equipment remote monitoring system, greatly lowering daily labor management difficulty for factory operators.

Working Principle

The core working theory of industrial reverse osmosis equipment relies on reverse osmosis membrane separation technology. Natural osmosis drives water molecules to flow from low concentration solution to high concentration solution across a semipermeable membrane. The equipment applies stable hydraulic pressure higher than raw water osmotic pressure on the feed water side of the RO membrane. Under pressure driving force, pure water molecules penetrate the polyamide semi-permeable membrane to form product pure water, while dissolved solids, suspended impurities and bacteria are intercepted on the feed side and discharged as concentrated brine.

The complete workflow contains multi-stage links: raw water pretreatment → security filtration → high-pressure boosting → membrane separation by RO elements → pure water storage. The pretreatment unit eliminates suspended solids, residual chlorine and scaling substances to prevent membrane fouling, which extends the service life of membrane elements. Operators can set recovery rate and flushing cycle through the control cabinet to balance water yield and membrane protection.

Technical Features

1. Flexible Membrane Matching: 

Supports configuration of multiple brands of RO membrane elements. Users can select high-salinity resistant brackish water membranes, seawater desalination membranes or low energy RO membrane to cut high-pressure pump energy consumption.

2. Intelligent PLC Automatic Control: 

Equipped with conductivity online monitoring, automatic membrane flushing, high/low pressure interlock protection, and optional remote data access via the RO equipment remote monitoring system.

3. Modular Skid Frame Structure: 

Standardized stainless steel frame assembly, convenient for transportation, on-site installation and later expansion. It can directly connect to the pipeline of the zero liquid discharge RO concentration system.

4. Customized Recovery Rate Design: 

Engineers adjust system structure according to local raw water quality to achieve reasonable water recovery rate and reduce brine discharge volume.

5. Complete Safety Protection: 

Built-in low-pressure protection for feed water, high-pressure protection of membrane pipeline, automatic shutdown alarm when abnormal conductivity occurs, avoiding accidental damage to core components.

Product Advantages

1. Outstanding operational economy:

Compared with traditional ion exchange demineralization technology, industrial reverse osmosis equipment does not require frequent acid and alkali chemical regeneration, greatly reducing chemical procurement costs and wastewater treatment workload. When matched with low energy RO membrane, the overall power consumption of the high-pressure system can be decreased significantly for long-term operation.

2. Flexible business solutions for different project cycles:

Apart from selling brand-new equipment, we supply industrial RO equipment rental/leasing for short-term production peak or equipment overhaul transition periods. We also provide RO equipment retrofit/upgrade service for aging original production lines. Instead of purchasing a whole new set, factories can upgrade control systems and replace membrane elements to restore production capacity.

3. Stable and consistent effluent quality:

The system continuously monitors pure water conductivity, effectively removing over 97% of dissolved salts. It meets standard requirements for process pure water in most industrial sectors.

4. Convenient maintenance and strong scalability:

The modular design allows customers to carry out existing RO system capacity expansion without large-scale transformation of factory buildings. Standardized components are convenient for global spare parts procurement and after-sales maintenance.

FAQs

Q1: Which type of RO membrane should be selected for my industrial reverse osmosis equipment?

A1: Selection depends on raw water TDS, target pure water conductivity and energy budget. For conventional brackish water,  BW30 Series high rejection RO membrane is widely adopted. If you aim to cut power consumption, you can choose low energy RO membrane. We provide raw water quality analysis to recommend matched membrane elements.

Q2: Can you carry out RO equipment retrofit on our existing aging reverse osmosis system?

A2: Yes. Our technical team can evaluate your original frame, pipeline and high-pressure equipment. We offer schemes including control system upgrading, membrane element replacement and existing RO system capacity expansion, avoiding high investment for complete equipment replacement.

Q3: When do we need to connect the zero liquid discharge RO concentration system with industrial RO equipment?

A3: If local environmental regulations restrict brine discharge, or factories hope to maximize water reuse rate, the concentrated water produced by industrial reverse osmosis equipment can be further concentrated by the ZLD RO system to improve water recovery and reduce wastewater discharge.

Q4: What pre-treatment devices need to be matched with industrial reverse osmosis equipment?

A4: Standard supporting pre-treatment contains multi-media filter, activated carbon filter and security filter. Proper pretreatment can effectively slow down fouling of high rejection RO membrane and low energy RO membrane. We can design an integrated pre-treatment + RO all-in-one skid according to your raw water conditions.

Q5: What effluent water quality indicators can your standard industrial reverse osmosis equipment reach?

A5: Equipped with qualified RO membrane elements, the system can remove more than 97% of dissolved solids. If higher purity water is needed, we can add polishing mixed bed or EDI after the RO unit, to meet ultra-pure water requirements of electronics and new energy industries.
