How to Clean Industrial RO Membranes?

Industrial RO plants serve as the basis for water treatment in companies, ensuring that water employed for production is clean. The most important aspect of an industrial RO plant that removes impurities, salt, and contaminants is the industrial RO membrane. With time, foulants such as organic waste, minerals, and biological growth foul industrial RO membranes, making them less efficient and effective. For keeping the plant operational and extending the life of the membranes, industrial RO membranes need to be cleaned regularly. Here, we are going to tell you why Industrial RO Membrane cleaning is important, step by step procedure followed, and how Netsol Water—the leading Industrial RO Plant manufacturer—can help you optimize your system.

Why is Cleaning Industrial RO Membranes Important?

Industrial RO Membrane cleaning is to maintain your Industrial RO Plant in the best possible way. When membranes become fouled by contaminants, filtering will be longer, thus leading to low water production, higher energy use, and higher operating costs. In severe cases, ongoing fouling can result in irreversible damage to the membranes at a great replacement cost.

The reasons behind cleaning having to be implemented are as follows:

• Flow Rate Restoration: Fouling clogs up the pores in the membranes, and that reduces the flow and efficiency of water. Cleaning revives the original flow rate.
• Improvement of Water Quality: Regular cleaning prevents the impurities from accumulating on the membranes, and that keeps the treated water quality to remain high.
• Extending Membrane Life: Cleaning as a maintenance process can extend your Industrial RO Membranes’ life with less replacement cost.
• Decreasing Energy Consumption: During fouling, the system must operate harder to push water through the membranes. Cleaning eliminates fouling, maximizes efficiency and saves energy.

When Do You Clean Industrial RO Membranes?

Cleaning depends on the quality of water, system design, and operating conditions. As a thumb rule, it is advisable to clean Industrial RO Membranes when:

• A Decline in Performance: Observe an excessive decline in permeate flow rate or rising pressure, and the plant might need just a good washout session.
• Increased Energy Consumption: More energy consumption within the plant might indicate fouling of the membranes.
• Water Quality Decline: Observe a reduction in quality for water being treated, or observe excess turbidity and conductivity, clean time is near.
• Pressure Differential: High differential pressure across membranes typically indicates fouling, which is to be cleaned.

Industrial RO Membrane Cleaning Processes

Two processes that are most often utilized for Industrial RO Membrane cleaning are: chemical cleaning and clean-in-place (CIP).

Chemical Cleaning

Chemical cleaning is the most prevalent method to clean Industrial RO Membranes. Chemical cleaning is a combination of chemicals as an attempt to drain the foulants like salts, organics, bacteria, and scales. Cleaning chemicals to use vary by fouling type, and the process usually proceeds step by step as follows:

• Preparation: Preparation of the cleaning solution is done according to the type of fouling (acid for scaling and alkaline chemicals for organic fouling).
• Circulation: Circulation of the cleaning solution through the system is done in a manner that the fouling on the membranes is dissolved by the chemicals.
• Rinsing: There is complete rinsing after cleaning for removal of chemical residues toxic to the membranes.
• Testing: The performance of the membrane is tested last in order to guarantee that cleaning restored the ideal quality and flow rate that they originally achieved.

Clean-In-Place (CIP)

CIP is a highly automated process, which is applied very extensively in Industrial RO Plants to achieve the cleaning of the membrane without taking down the system. It involves passing a cleaning solution through the system with undisturbed membranes. It is relatively simpler and quicker than regular cleaning processes and involves very little human intervention.

CIP typically includes:

• Preparation of Cleaning Solution: A cleaning solution is blended with desired chemicals.
• Circulation: The solution is passed through the system for a set duration of time in order to free the impurities.
• Rinsing: The system is then rinsed using clean water once circulation has been performed in order to remove the cleaning chemicals.
• Performance Check: The system is inspected for efficiency after cleaning has been carried out.

Tips for Effective Cleaning of Industrial RO Membranes

Use Proper Cleaning Chemicals: Utilize cleaning chemicals appropriate for the fouling type. Toxic chemicals to the membranes can be formed if improper chemicals are applied.

• Control pH: Keep the pH level within the specified parameter for the cleaning solution to prevent membrane damage.
• Maintenance Schedule: Periodically inspect the membranes for excessive wear. Preventive maintenance can prevent the membranes from being over-cleaned.
• Optimize Cleaning Interval: Over-cleaning causes damage to the membrane. Optimize the interval by cleaning as required.
• Check Scaling or Biofouling: Different fouls (scaling, organic, or biofouling) require different cleaning methods. Check the cause of fouling prior to cleaning.
