Haigh’s range of ACE Screeners® cover inlet flows from 2-150 l/s and are designed specifically for use in waste water and sewage treatment works. Installation flexibility is a key attribute, allowing project designers to use an ACE Screener® in virtually any situation, including retrofit into existing civil structures, new build channels, or as pipeline sections.

Screenings are an unavoidable but unwanted by-product of sewage. The ACE Screener® produces the minimum screenings residue by putting as much of the organic material back into the flow. The small amount left over is then dewatered, compressed and dried. The original screenings volume is reduced by 94% so bin and skip use as well as odour are considerably reduced.

The ACE Screener® requires no wash water whatsoever. Often the cost of potable or piped-in water is not included in the whole life cost of an installation and up to 70 tonnes of water are used by some products per day. On this basis the capital cost of a Screener® can soon be recovered.

Used in conjunction with a Carriskip this system removes the dependence on individuals to manually empty a bin and gives far greater health and safety security when handling screenings. The Carriskip provides a man-portable bin that can be sealed, stored and transported easily. Individual Carriskips will be lined with a standard plastic bag, once full the bag can be tied closed sealing the screenings in. The tops of the Carriskip can be folded over to keep everything secure.

Carricell is a system of multiple Carriskips designed for larger sites where single Carriskip boxes would fill quickly and for remote sites which are difficult to monitor.
