Colloide install rotating half bridge scraper systems at Earlston WwTW

Earlston Wastewater Treatment Works (WwTW) General Project Overview

 

 

Colloide were awarded the design, supply and delivery of 3no. rotating half bridge scrapers for one 11.8m Primary Settlement Tank (PST) and 2 Humus Settlement Tanks (HST) at Earlston Wastewater Treatment Works (WwTW) in collaboration with ESD or Scottish Water.

Earlston WwTW is located on the bank of the Leader Water in the Scottish borders, local to the town of Earlston. Earlston WwTW is a traditional biofilter works with an inlet screen, storm storage, 1 No primary settlement tank, 2 No. biofilters and 1 submerged aerated filter, and 2 humus settlement tanks. The primary settlement tank and existing humus settlement tank required the removal and complete replacement of the half bridge scraper arrangement system, including all associated ancillaries. A newly built humus tank on site also required an 8.76m rotating half bridge scraper in order for the works to cope with current demand.

The following installation had to be carried out in a manner that did not cause any deterioration to the existing plant’s consent performance.
