WCS Environmental Engineering (WCSEE) will showcase the game-changing Flocell XFM phosphorus-reducing filtration solution at the Water, Wastewater and Environmental Monitoring (WWEM) event - part of the Environmental Services and Solutions (ESS) Expo, taking place on 17th–18th September at the NEC, Birmingham.

Flocell a business division of Evolution Aqua Group partnered with WCSEE to adapt its proven technology, originally developed for the aquaculture fish keeping pond filtration, for the demands of the wastewater treatment sector.

Proven Technology, Adapted for Wastewater

With over two decades of success in the aquaculture sector, the Flocell technology has been modified to meet the requirements of tertiary solids and phosphorus removal in municipal and rural wastewater treatment applications.

Field-Proven Performance

The adapted Flocell system was successfully trial at United Utilities’ Appleby rural wastewater treatment works (WwTW) and has since been deployed by leading UK water utilities including United Utilities, Severn Trent, Dŵr Cymru Welsh Water, Southern Water, and South West Water.

In the United Utility trial, the system achieved phosphorus concentrations significantly below 0.25 mg/l when combined with chemical dosing. Over 1,000 samples were analysed for particle size distribution and total suspended solids (TSS), confirming the system’s robust and consistent performance.

Single-pass and multi-pass ‘dialysis’ mode configurations

The units can operate under both pumped and gravity flow and support single-pass and multi-pass ‘dialysis’ mode configurations, offering flexibility across a wide range of site layouts. The multi-pass ‘dialysis’ mode enables recirculation to the Final Settlement Tank (FST), creating a loop that enhances overall system protection by providing additional buffering capacity.

The open-cell media is designed to efficiently reduce tertiary solids and soft, difficult-to-manage flocs, retaining particulates without increasing pressure within the filter or reducing flow.

Unique Filter Cleaning Cycle

The filtration system features a distinctive Air Clean technology, which replaces the traditional backwash cycle commonly used in filtration systems. During the cleaning process, low-energy blowers gently agitate the media pack to dislodge and remove trapped solids. This air-based method allows the filter to be drained rather than backwashed, significantly reducing water loss.

With no moving parts or hydraulic pressure within the filter, the Flocell also achieves lower energy consumption and operates without the need for process water, offering a simple, efficient, and low-maintenance cleaning process.
