Optimising RGF Performance Through Regular Cleaning
Are your Rapid Gravity Filters (RGFs) losing efficiency, driving up costs, or requiring frequent maintenance?
The PM cleaning system is a proven solution that restores filter performance, extends filter life by up to 2.5 years, and reduces operational costs. Backed by over a decade of research and successful application across 30+ filters, our PM77 cleaning system is a game-changer for water utilities looking to optimise their filtration systems.
Let’s Dive In: Key Insights on RGF Filter Cleaning
Boost Flow Rates & Reduce Pressure
The PM77 cleaning system has been researched, trialed and perfected since 2014, delivering consistent improvements in underdrain pressures and backwash flow rates. Filters cleaned between 2021 and 2023 saw an average recovery of 18.3 mbar in underdrain pressures and a 156 L/s boost in backwash flow rates.
- Improve filter efficiency: Restore your filters’ performance to optimal levels without costly replacements.
Extend Filter Performance by Up to 2.5 Years
Our cleaning service extends the performance of RGF filters by up to 2.5 years, avoiding expensive media replacements and structural repairs. Since 2018, more than 30 filters have been cleaned using PM77, with measurable improvements in both filter longevity and performance.
- Save on maintenance costs: Prolong filter performance and avoid the expense of frequent repairs and replacements.
Prevent Costly System Failures
Poor backwashing performance due to blocked underdrains and filter floors can lead to structural failures, media loss, and compromised water quality. Regular, low-intervention cleaning prevents major system breakdowns, saving your plant from costly emergency repairs.
- Avoid damage: Reduce the risk of filter floor failures caused by high backwash pressure or poor filtration performance.

Long-Term Results
The Results Speak for Themselves
Underdrain Pressure Recovery
Filters cleaned between 2021 and 2023 saw an average reduction of 18.3 mbar in underdrain pressure, relieving stress on your system and improving flow.Boosted Backwash Flow Rates
Post-cleaning, backwash flow rates improved by 156 L/s, maintaining optimal filtration for extended periods.Extended Filter Performance
The cleaning process has extended filter performance by up to 2.5 years, minimising the need for disruptive and costly media replacements.Sustained Efficiency
Filters maintained higher-than-previous flow rates for up to 2 years, helping facilities operate efficiently without interruptions.Over 30 Filters Cleaned
Since 2018, more than 30 filters and counting have been restored using our RGF cleaning system, proving its reliability across various sites.Restore Both Media and Filter Floors
Initially, we focused on cleaning clogged media to avoid replacements. However, we discovered that natural material build-up in both filter floors and underdrains is a major cause of poor backwash performance, leading to media deterioration.
Our cleaning process targets both the media and the filter floors, ensuring optimal backwash efficiency and improving the performance of your entire filtration system.
