Challenge

Hydro International were asked by United Utilities to look at a range of options for improving phosphates removal at its Congleton and Saddleworth wastewater treatment works.

One of the criteria, apart from meeting the set limits, was to expand the range of technologies that United Utilities was using so as to have a more diverse range of solutions.

Solution

Phil Algawi, Project Manager for Nomenca: “Before recommending the Hydro solution to United Utilities, we examined the operation of a DynaDisc® at an established site elsewhere in the country and were very impressed with its operation. Hydro worked with us very professionally to achieve an installation that met the specifications of a compact site and satisfied the requirements of United Utilities.

The DynaDisc® installations have been successfully completed at both plants in a project to supplement secondary trickling filter beds treatment. Nomenca Ltd, the specialist Mechanical, Electrical, Instrumentation, Control and Automation (MEICA) contractor, also installed new dosing systems and integrated the new equipment with existing instrumentation systems as part of United Utilities’ AMP5 investment programme.

Both DynaDisc® units are capable of treating 100% of the final effluent flow, but will normally operate at 50% duty with standby to ensure continuous service. The DynaDisc® mechanical disc filtration system from Hydro International offers high efficiency microscreen filtration which can be precisely tailored to wastewater composition, flow and discharge requirements. As part of the filtration process the removed solids and backwash are returned through the site systems for treatment.

Outcome

Phil Algawi: “We found DynaDisc® easy to install, connect to the existing site systems and commission. Following the installation we conducted a successful fourteen day trial.”
