Band Screens

Jacopa offer two types of band screens from their J+A and Brackett Green design product ranges.

The Brackett Green® CF100®  and CF200®  band screens are just two of a line of successful proprietary products in Jacopa’s range and are specifically designed for water & wastewater treatment screening applications with flows from 25 to 5000l/s with varying channel depths and screening apertures of  2mm, 3mm, 5mm or 6mm.

Jacopa has an exclusive licence for Brackett Green products for Municipal Markets in the UK and Ireland.

Utilizing Brackett Green’s decades of experience, Jacopa is the world leader in screening technology. Whether your requirement is for new or old treatment works or to optimize an outdated screen, we can provide the right solution for you. Brackett Green® screens have been tested at the National Screen Evaluation Facility in the UK, with excellent results. The Brackett Green CF200® and CF100® band screens proved screen capture rates of 80% based on 6mm screening apertures and in some cases with small apertures up to 93% SCR, with virtually no wear after an extensive testing period.

Brackett Green screens are fully W.I.M.E.S compliant and all Brackett Green band screen products are manufactured to ISO9001 standards and are subjected to rigorous internal quality audits, ensuring that only the best quality screens are delivered to our clients.

CF200 and CF100 screens adopt a central flow pattern, i.e. water enters the centre of the screen first. Jacopa’s research has proved that the central flow pattern is the most efficient means of removing suspended solids for wastewater applications. This pattern also eliminates the problem of “carry over” found in more traditional straight-though and step type screens. Wastewater enters through the centre of the fine screen and flows outwards through a moving band of heavy duty polymer mesh panels to the outside of the screen chamber. Screenings are retained on the inside of the screen panels, and are discharged by low pressure water jets at deck level during the cleaning cycle. Water jets are mounted onto a jet pipe inside the screen head section. During the cleaning cycle these jets continuously clean the panels as they pass the discharge point above the debris hopper. A removable end cap is fitted to the jet pipe for flushing. If wash water is unavailable, a pressure switch prevents screen operation.

Brackett Green CF200 and CF100 band screens are fitted with tapered or parallel holes in thick polymer mesh panels (9mm thick). Unlike steel or other metallic mesh and plates, the panels actively discourage hair-pinning. These highly effective screens do not require brush cleaners, removing a source of constant problems found on alternative machines.
