HUBER Belt Screen EscaMax®

HUBER Technology recently completed the installation and commissioning at Melton Mowbray STW
By: Huber Technology
Published: October 6, 2024

HUBER Belt Screen EscaMax® installation at Melton Mowbray STW

Melton Mowbray STW is a medium sized activated sludge works, treating a PE approx. 68,000. The works treats a combination of both domestic and trade effluents. The new Melton Mowbray STW is designed to cater for increased treatment flows equating to a design horizon population equivalent of 123,328 (82% growth) and a tightening of the phosphorus and ammonia permits. A significant proportion of the influent is from trade waste. Huber Technology was heavily involved in the design and planning of the new inlet works with MWH and Severn Trent Water to replace the two existing 6mm screens with three 6mm screens and installation of wash compactors.

Early involvement with MWHT, through site visits and meetings enabled a proven solution to be designed for both screenings and screenings handling requirements. Severn Trent should hopefully see the huge benefit this technology brings to the downstream process very quickly.

Huber was involved in part of the innovative solutions to ensure the re-use of the existing inlet structure in lieu of a new structure. The existing two HUBER screen installation with centre by-pass channel was designed to be replaced by three new HUBER Belt screens EscaMax® and two HUBER Wash Press WAP® L compactors. This was further complicated as the refurbishment had to fit the existing inlet works. This was achieved by the provision of a new bypass pipe outside the inlet works structure and the use of the existing centre bypass channel to house the third screen. Huber worked collaboratively with MWHT to ensure that this was achieved.

Objective & Solution

The main objective was the efficient refurbishment of the inlet works with installation of three new HUBER screens and two HUBER wash compactors on a phased changeover at the inlet. HUBER completed the mechanical installation over three stages with commissioning being completed in stages (in between the install stages) before the next machine was installed as the site needed to have at least one EscaMax® running throughout the installation process.

David Foster McBride (Area Sales Manager) commented on the project:

“Early engagement with the customer allowed for a suitable innovative solution to be selected to handle the design parameters and be successfully delivered within the existing inlet works limitations. The project was delivered on time and to budget and is an excellent demonstration of close involvement with Severn Trent Water and MWHT.”
