Pulp & Paper
Fournier Rotary Press excels in handling sludge from diverse range of raw materials, from fresh fiber to recycled board and paper, meeting the varied needs of Pulp, Paper, and Board mills.
Liquid-solid separation processes for the future.
For the Pulp & Paper industry, the liquid-solid separation or dewatering process faces many of challenges. A wide mix of raw materials, sludge consistency, work-processes and stock preparation adds to challenges such as removing impurities, recycling valuable fibers or maintaining process-water in the production loop. Add to this the ever increasing cost of energy and stricter emission rates, the demand for higher effiency, lower polymer usage and better working enviroment will be necessary to ensure sustainably operation in the years to come.
Optimizing the dewatering process can yield an increase in output of valuable and recyclable fibers, allow for higher recycling of process water in the production loop and also help minimize wear and tear on pumps, piping and other equipment due impurities in the liquid.

Fournier Rotary Press™
With it's small installation footprint, slow rotation and low noise-level, installations can be accommodated without additional changes to site and work-area, meaning little need for extra investment and time before production-start.
The FOURNIER Rotary Press™ offers versatile models for solid-liquid separation, suitable for high-fiber sludges (CVP) and biological sludges (CVH). Modular and expandable systems allow for future capacity increase - simply bolt-on another channel.
The technology operates effectively across various slurry types and waste streams. With slow rotation, it achieves high cake total solids percentage and superior filtrate quality at low total suspended solids content. The system handles inlet consistencies between 0.5% and 10%, potentially replacing prethickening and main dewatering equipment.
Recognized for operational flexibility and low operating expenses due to high efficiency and low power consumption, the system features an enclosed design that prevents odour emissions and maintains a clean machine environment. Add to this a high level of automation and operational reliability that minimizes operator attendance and intervention times and futher saves OPEX.
Performance data is supported by lab sludge testing and full-scale pilot tests with a containerized pilot unit at an industrial scale.
Highly effective dewatering at lower OPEX.
The FOURNIER ROTARY PRESS™ has many advantages over other dewatering technologies and offer substancial saving in running operation costs.
The slow rotational speed and the high efficiency of the Fournier Rotary Press™ provide at higher %TS in the cake - yielding a high dryness cake.
By efficiently reducing the moisture content of paper sludge, the Fournier Rotary Press™ enhances its calorific value and makes it more suitable for alternative applications. This could open up new avenues for repurposing and recycling the process wastes, and so opening up for increased recycling fibers and a more sustainable waste management.
Lange Lyche Teknisk offer pilot testing with moblie containerized Rotary-press pilot test units, enabling full scale pilot testing with your unique sludge - giving a reliable read on expected production figures and filtrate quality. Contact us for more information about pilot testing.
