INTRODUCTION Filtration experts, over the years, have discussed and debated filter presses and have indicated that soon they would be a thing of the past; the last filler press would be replaced by more modern equipment. Given that filler presses were amongst the oldest mechanical dewatering devices, this was a fairly plausible suggestion. However, now. almost half a century later, any chemical engineering exhibition shows that filter presses are alive and well and are going to be around for years to come. True, they look different from the ones in the 1950's, but essentially they are still the same device. Their continued presence is a tribute to the filler press manufacturers who embraced new materials and upgraded the mechanics and configurations. However, the basics are still the same and much of the issues surrounding filler presses remain valid.

This article discusses the perceived shortcomings of the filter press as well as batch or continuous filtration alternatives to them based upon the process conditions and requirements of the chemical operation. HISTORICAL PROBLEMS WITH FILTER PRESSES

Lethbridge WTP Residuals Management Upgrades – Improves its Environmental Impact

Waste’n WaterTech is proud to have been involved in the City of Lethbridge Water Treatment Plant Residuals Management Upgrade where three 8-channel Fournier Rotary Presses were installed and commissioned in March of 2020 to dewater up to 1,000 dry kilograms per hour of waste residuals generated by the plant, thus avoiding these being discharged back into the river. The Fournier units are being fed sludge by three of our PL300 Boerger Rotary Lobe Pumps. It was a pleasure working with Maple Reinders, MPE, and...

London’s Greenway WWTP chooses Flottweg

Located along the Thames River, London Ontario’s Greenway wastewater treatment plant takes in sludge from six other city treatment facilities. Upon arrival, sludge dewatering is achieved using three C7E Flottweg centrifuges. The plant currently treats approximately 17,000 dry tons of sludge per year. After it is burned, left over ash is hauled to a nearby landfill. “Odour control was an issue,” said Angelo Marcoccia, maintenance manager at the Greenway plant. “With a centrifuge, everything...

Advantages of multi disc screw press in treating food sludge wastewater

Food has a wide range of industrial raw materials and a wide variety of products, and the amount and quality of discharged wastewater vary greatly. The sludge of the food factory has the characteristics of high moisture content and high organic content in the sludge. Therefore, the adjustment and modification of sludge is a key point.There are many methods for modern food wastewater treatment, and the common methods currently belong to physical treatment, chemical treatment and biochemical treatment. Bioetp's...
