Phosphorus removal using DAF meets tight watercourse discharge permit for UK drinks manufacturer

24 April 2023

MSE Systems has overcome significant on-site space challenges and a limited timeframe to deliver an enhanced phosphorus reduction pre-treatment solution to a major UK drinks manufacturer. In a matter of days, MSE Systems installed a mobile DAF unit into a tight footprint at the customer’s site, delivering almost instant results for reducing Phosphorus levels in the wastewater. The new ‘plug and play’ DAF system enables the drinks’ manufacturer to meet the stringent permit limit of < 1 mg/l Total Phosphorus for the final treated effluent to watercourse.

The mobile DAF unit now provides an enhanced phosphorus reduction pre-treatment step using chemicals, whilst still retaining enough phosphorus to supplement the subsequent biological treatment process at site.

Phosphorus is an important trace nutrient required for optimum biological treatment; chemical removal must be carefully controlled to ensure that it does not create a phosphorus deficient wastewater that could reduce the biological treatment efficiency.

The rapid deployment of a mobile DAF unit, the majority of which was manufactured off-site, also ensured minimal downtime during the on-site installation.

The small footprint available at the site was overcome using one of MSE Systems’ mobile DAF units and dosing container, which were both crane lifted into position. The units were connected into the existing system, powered up, and fully working within days.

Ahead of the installation, MSE’s lab technicians worked closely with the customer conducting jar tests to identify the optimum chemical dosing regime required for the smooth running of the process.

Huw Thomas, Director of MSE Systems explained: “The jar tests we conducted ahead of the installation gave us a head start when the unit was installed on site and enabled us to get the system fully operational more quickly. Doing the pre-tests also enabled us to establish the optimum process of physiochemical pre-treatment on the DAF unit required to reduce the levels of phosphorus in the system.”

Huw added: We’re very proud of the high level of automation that we have been able to build into this unit which includes a level of remote monitoring.”

A dedicated service back-up team supplied by MSE will now ensure the units continue to deliver optimum results at all times.
