Efficient Wastewater Management with Fournier Rotary Press

In the quest for sustainable waste management solutions, the Fournier Rotary Press stands out with its performance and efficiency. Tailored to meet the demands of municipal and commercial wastewater treatment plants, our technology confronts the challenges faced by industries across Europe.

Our Rotary Press offers a pragmatic approach to managing high energy costs, legislation compliance, and the imperative to reduce fresh water usage. This solid-liquid separation solution features a range of CVH model sizes, from a single dewatering channel up to eight, adaptable to both small and large sludge volumes. The press operates across all sludge types, including primary, septic, and both aerobically and anaerobically treated slurries.

The handling of dewatered sludges is traditionally marred by high transportation costs. Rotary Press Technology redefines this narrative by maximizing dewatering efficiency, reducing sludge volume, and consequently cutting down on transport expenses.

Navigating Tight Regulations

Legislative demands, often complex and stringent, require a precision-oriented approach to compliance. With the Rotary Press, businesses can achieve higher capture rates and cleaner discharge, surpassing regulatory thresholds. This not only shields businesses from compliance risks but also establishes their reputation as environmentally responsible entities.

Increase dewatering output with

Fournier Rotary Press™

With it's small installation footprint, slow rotation and low noice, 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.

With it's high efficiency and low power consuption, the FOURNIER Rotary Press  is recognized for operational flexibility and low operating expenses, it features an enclosed design that prevents odour emissions and maintains a clean machine environment. A high level of automation and operational reliability minimizes operator attendance and intervention times.

Enhancing Solid-Liquid Separation Efficiency

Highly effective dewatering at lower OPEX.

Traditional dewatering equipment may fall short of today's efficiency needs. The Rotary Press stands out with its superior solid-liquid separation capabilities, minimizing water content in the sludge and elevating the overall process efficiency to meet and exceed industry standards.

The FOURNIER ROTARY PRESS™ has many advantages over other dewatering technologies and offer substancial saving in running operation costs.

Focusing on operational efficiency, our Rotary Press technology achieves high cake dryness percentages and excellent filtrate quality with low total suspended solids (TSS) content. This performance is maintained with varying inlet consistencies, from 0.5 to 10%, demonstrating its robustness and versatility.

The modular design allows for tailored capital expenditure and capacity expansion without compromising on efficiency. With the best-in-class operational flexibility and the lowest operating expenses across its life cycle, the Rotary Press is designed for low operator attendance, thanks to its high automation and reliability.
