Low-maintenance horizontal drum screens debut at Ozwater '21

CST Wastewater Solutions introduced its horizontal in-channel rotary drum screening technology at Ozwater’21 in May.

According to the company, horizontal drum screens have a number of advantages over incline systems, including an efficient engineering concept and thorough detail engineering, which combine to produce low whole-of-life costs when compared with most other screens, with servicing required only every 4–6 years.

CST’s Australian-manufactured horizontal drum screens are capable of 5 mm or finer screening on flows up to 2000 L/s. They are suited to municipal inlet works; pre-membrane systems; pulp and paper mills; food and beverage, including abattoirs; manufacturing; tanneries; and a broad range of industrial and municipal applications.

Advantages of horizontal drum design include: 5 mm or finer screening on flows up to 2000 L/s; low fluid head loss at peak flows for increased solids removal efficiency; robust stainless steel construction; simple maintenance — all parts located above wastewater flow; all routine servicing without removing the drum; robust engineering, design and construction; long typical service life of 7–10 years.

Advantages over inclined drums include: lower maintenance and downtime with improved seal and brush replacement cycle times; inclined drums tend to have high levels of recycling back to inlet, which is not suitable for MBR protection — horizontal drum designs avoid this issue; more flexible operation — with inclined systems, the front bearing collects screening and rags, which can foul with the seal and cause early failure; integral lifting screws are located above the wastewater flow for easy maintenance and general housekeeping.
