Avoid costly mistakes when running your MBR system

Membrane Bioreactor (MBR) systems offer numerous advantages, but they are a significant investment so it's important to consider factors such as initial capital costs and maintenance requirements when considering if they’re suitable for your wastewater treatment plant, or indeed if you are already running an MBR system on your site.

We've highlighted the benefits and the risks on the infographic below, and go on to explain how to mitigate some of the risks to ensure optimal performance of your MBR system and maximise the return on your investment.

As experts in the operation, maintenance and recovery of MBR systems, we've explained how to avoid the potential risks of ineffective management of these complex systems.

1. Complexity of Operation

MBR systems can be more complex to operate and maintain than conventional treatment processes. Ensuring your team has the right training, skillset and support is essential for optimal system performance.

2. Membrane Fouling

Fouling (where substances accumulate on the membrane surface) can reduce filtration efficiency and increase energy consumption. Regular preventative maintenance and cleaning are necessary to avoid issues. Read our case study to discover the devastating effect fouling can have on performance and cost, and how we recovered and extended the membrane lifespan for a leading UK plant-based F&B manufacturer.

3. Energy Consumption

MBR systems that incorporate tubular membranes may require significant energy inputs, especially for aeration in the biological treatment process and pumping of water through membranes. Escalating energy costs can be prevented by close monitoring of performance and proactive cleaning and maintenance to prevent build-up.

4. Sensitivity to Shock Loads

MBRs can be sensitive to sudden changes in influent characteristics or shock loads, which may affect system stability and efficiency. Close monitoring of pre-treated effluent, communication with the production team and swift reaction to changes can minimise the effects and disruption.

5. Membrane cleaning costs

Ineffective Cleaning in Place (CIP) and maintenance can cause build-up which could lead to an increase in cleaning chemical costs or the requirement of one-off cleans. Close monitoring, combined with proactive cleaning and maintenance keeps costs to a minimum. We recently helped Bakkavor save 76% on cleaning chemical costs by making improvements to the process and changing the chemicals used (and supplier).

6. Membrane Replacement Costs

Over time, membranes may need replacement due to wear and tear. The cost of membrane replacement can be a significant factor in the long-term operation and maintenance budget – however expert proactive and preventative membrane maintenance can increase their lifespan by years to deliver extra value to the bottom line.ls used (and supplier).

Engaging an expert, such as Alpheus to operate and maintain your MBR plant may save you money versus operating the plant yourself. We've written a guide to the benefits of outsourcing and how it could reduce operating costs.
