Why is FilterClear the leading solution for low phosphorus consents across the UK water industry?

During AMP6 and the CIP2 phosphorus removal trials, the focus was on identifying those tertiary solids removal (TSR) technologies that could achieve the stringent phosphorus consent requirements demanded in AMP 7 and beyond. FilterClear was one such technology that proved capable of meeting even the most stringent consents across the UK.

But stopping there would be doing a disservice to our clients and the public who rely on the safe and reliable provision of water & treatment and discharge of wastewater.

?Both the trials and real-world experience has highlighted that the key to achieving consistently reliable results is upstream optimisation and TSR maintenance.

The market now knows which technologies can hit the consents; knowing those that not only hit them but continue to perform under challenging operating conditions and over a long period of time is critical. After all, a failure leading to a pollution incident is a failure nevertheless; past performance counts for nothing.

Breaking the routine

FilterClear’s extremely efficient backwashing regime eliminates the need for routine out of service mechanical and chemical media cleans associated with other TSR technologies. Backwashes are initiated automatically triggered by differential pressure or elapsed time. Manual initiation of a backwash is also a simple task via the HMI. Importantly operators are not exposed to wastewater for cleaning operations.

However, we recognise that sewage treatment works can have mechanical breakdowns, instrument failures, blanket spills or other events which can cause some fouling in any TSR process.

In the rare event that remedial action is required to remove any unwanted fouling from the media, simply soaking the filter media with alkali during a backwash quickly restores normal operation.

An “alkali soak” function has been incorporated into FilterClear’s software. This procedure eliminates the need for expensive specialist cleaning services or manual cleaning by Operations staff. The Operator simply activates the “alkali soak” function on the control panel and the cleaning process proceeds automatically, eliminating manual handling and contamination risks.

When prompted, the Operator adds alkali pearls to the vessel via the top hatch. The air scour blower mixes the alkali and agitates the filter media. After soaking for 1 – 2 hours, the alkali breaks down the fouling and it is flushed from the system, just like a regular backwash.
