For Screenings, Grit and Sludge

Longopac Fill bagging system

A closed bagging system for grit, screenings and sludge. The handling of screenings, grit and sludge is a well known environmental and health problem in all sizes of sewage treatment plants. Even with improved ventilation in most screening and press buildings, a high concentration of bacteria and fungus spores can develop. Longopac Fill solves your problems in both a practical and efficient way.

The handling of screenings, grit and sludge is a well known environmental and health problem in all sizes of sewage treatment plants. Even with improved ventilation in most screening and press buildings, a high concentration of bacteria and fungus spores can develop. These factors can produce poor air quality; this can lead to an unhealthy working environment and result in increased probability for chronic asthma, allergies and diseases in the pulmonary tissues and the intestinal tract. Longopac Fill solves this problem in both a practical and efficient way. Longopac Fill consists of a closed bag system, which can easily be connected to the discharge point of your machine.

The screenings, grit or sludge is deposited into the continuous Longopac bag, which will also provide odour containment and help control spillage associated with the collection of wet screenings and grit. The Longopac is easy to seal and the material and odours are trapped inside the Longopac bag. LONGOPAC FILL ADAPTER AND HOLDER The cassette holder is manufactured in ABS plastic and the adapter is manufactured in stainless steel. It is designed to fit on any discharge chute with an outside diameter up to 460 mm. Longopac BAG CASSETTE The cassette is a continuous liner, manufactured in environmentally sound polythene that can be incinerated without any hazards. Each cassette bag is 90m respective 45m long.
