Reduce Annual Filter Expenditure with Smarter Consumable Filtration Management

Reduce Annual Filter Expenditure with Smarter Consumable Filtration Management
Consumable filtration, including cartridge filters, bag filters, and pre-treatment systems, represents a significant recurring cost in water and process filtration systems. While individual filters may seem inexpensive, inefficient use, suboptimal replacement schedules, or poorly designed filtration systems can dramatically increase annual expenditure and operational downtime. Optimising consumable filtration is therefore a key strategy to reduce costs while maintaining reliable system performance.

Why are filtration expenses rising year after year?

  • Frequent replacements due to poor system design: Incorrect sizing, high differential pressures, or mismatched flow rates can cause filters to reach end-of-life faster than expected.
  • Excessive fouling from variable feed conditions: Changes in water quality, solids loading, or suspended contaminants accelerate filter exhaustion.
  • Unplanned downtime and emergency replacements: Last-minute procurement of filters often incurs premium costs and interrupts operations.

BHF always looks at the “Cost of Filtration,” which is very different from the “Cost of a Filter.” The cost of filtration considers every stage of the filtration process and is impacted by the number of change-outs, labour time, disposal costs (both financial and environmental), chemical costs from re-sanitisation, and the cost of production downtime.

“It’s not uncommon to quadruple filter life by choosing a better quality filter. It may have 1.5 or 2× the price, however the outcome is far better,” said Deven Wesley, BHF National Sales Manager ANZ.

What are the benefits of an optimised filtration program?

1. Reduced Annual Filter Costs

Optimising filter selection, sizing, and change-out frequency ensures filters are used to their full operational life. Proactive planning avoids unnecessary early replacements and reduces annual expenditure.

2. Improved Operational Reliability

Proactively managing filter life prevents sudden pressure drops, flow restrictions, and system disruptions. Regular, optimised filter changes help maintain consistent system performance and reduce the risk of unplanned downtime.

3. Reduced Chemical and Water Usage

Efficient consumable filtration reduces fouling and scaling downstream, lowering the frequency of cleaning cycles and chemical dosing. Less aggressive cleaning extends the lifespan of membranes and associated equipment while reducing costs and environmental impact.

4. Predictable Maintenance and Inventory Planning

Monitoring differential pressure, flow rates, and water quality indicators allows operators to plan filter changes rather than react to emergency failures. Data-driven replacement schedules support efficient inventory management and minimise premium rush orders.

Implementing a Data-Driven Filtration Strategy

  • Monitoring system parameters: Differential pressure, flow rates, and turbidity provide insight into filter condition and life expectancy.
  • Analysing historical filter usage: Patterns of premature exhaustion or under-utilisation inform sizing and replacement strategies.
  • Tailored replacement schedules: Using operational data, replacement plans can maximise filter life while maintaining system reliability.
  • Continuous optimisation: Ongoing review ensures filtration strategies adapt to changing feedwater conditions, seasonal variability, and operational requirements.

Optimising consumable filtration is a cost-effective strategy that delivers both financial and operational benefits. By selecting the right filters, implementing data-driven change-out schedules, and tailoring maintenance programs, operators can significantly reduce annual expenditure, minimise downtime, and enhance system reliability.
