Tuke and Bell offer a complete range of rotary scrapers for primary and secondary settling tanks, for sewage works and water treatment plants. The range is manufactured to standard designs but can be specially adapted to suit individual requirements.
After the initial screenings and grit extraction of crude sewage, the effluent is settled to remove further solids as sludge – this is known as primary settlement. After biological treatment the sewage is settled again to remove humus sludge – this is known as final settlement.
Settlement is typically carried out in concrete tanks with a scraper mechanism used to collect the sludge for easy removal.
Refurbishment and Replacement of Existing Equipment
Tuke & Bell can refurbish and/or replace any other settlement tank equipment manufacturer’s equipment into their respective existing tank.
