Our rotary press demonstrates Fournier's commitment to continuous improvement. The result of many years of research and development, this state-of-the-art, proven technology has revolutionized the dewatering process.

The performance of a Fournier Rotary Press stands out; it typically uses less electricity and requires minimal operator attention compared to equipment like belt filter presses or centrifuges, often resulting in lower operational costs and better dewatering efficiencies.

The rotary press from Fournier Industries uses two slowly rotating screens to create a 2-inch-wide channel that the sludge passes through as it dewaters. A pressure restrictor on the press outlet allows the operator to vary the degree of cake dryness in the final product. The unit has few components and is designed for ease of maintenance and unattended operation.

How can a rotary press help them achieve those benchmarks? MJ: The capture rate of a rotary press is the highest of the dewatering devices that we have had over the years. Capture rate is the number of particles removed on the first run through a rotary press — and it's 98 to 99%. Compare that to a belt press at 75–80%.

A rotary press dewaters sludge using a cylindrical vessel housing two slowly-rotating (at < 2 RPM) circular permeable screens which are sandwiched together.

The ROTARY PRESS is at the heart of the dewatering process, completed by sludge and polymer feed systems. The principle of operation is simple. Sludge is fed into a rectangular channel, and rotated between two parallel revolving …

Rotary press dewatering relies on gravity, friction, and pressure differential to dewater sludge. Sludge is dosed with polymer and fed into a channel bound by screens on each side.

A pilot test is the most effective way to decide a sludge's dewatering potential with the Fournier Rotary Press TM. It is important to underline that the Fournier Rotary Press TM channels on the pilot unit are full-sized, giving accurate …

How screw presses work. A screw press (SP) provides sludge dewatering by conveying the sludge along the inside of a permeable cylinder. It is based on a slowly-rotating (~5 RPM) Archimedean screw within a cylindrical screen (otherwise termed drum filter/screen or basket).It is normally inclined by ~20° to the horizontal to assist with the draining of water into …

PRIME ROTARY FAN PRESS® 2.0 patented Revolutionary. All the benefits of the original Rotary Fan Press, plus: • Designed for sludge that releases moisture at a slower rate. • Ultra-advanced, simplified low-shear dewatering device with a patented internal mixing element. • Drier cake solids with higher throughputs at a lower cost. SPECS

This document summarizes Fournier Industries' rotary press sludge dewatering technology. It provides an overview of the company and the rotary press process. Key points include: - Fournier Industries has been building rotary presses since 1989 and has over 488 installations worldwide. - The rotary press is a fully enclosed, continuous screw-type dewatering device with few moving …

This case study from the Glasgow (Kentucky) Wastewater Treatment Plant shows how a Fournier Rotary Press helped it increase its dewatering capacity and save money February 19, 2024 Filed Under

The Prime Solution Rotary Fan Press is an easy-to-use, cost-effective dewatering solution that produces very dry cake with minimal oversight and maintenance. Watch the video to see how the Rotary Fan Press works.

Volute Dewatering Press CONCEPT The PWTech® Volute* Dewatering Press is a unique product, originally developed in Japan, that offers many advantages over current sludge management practices. Patented world wide, the Volute Dewatering Press is presently used in over 2,800 installations. The key to the process is the "dewatering drum." This drum

Rotary drum thickeners Dewatering Dewatering processes mechanically remove a significant proportion of the sludge water to produce a 15-45% cake product. Belt filter presses Centrifuges Drying beds Filter presses Lagoons Rotary press Screw presses Drying

But what sets the rotary press apart is its ability to offer high-performance dewatering with a simplified plug and play installation, and an energy-efficient, and less-labor-intensive operation. The continuous low-speed operation reduces wear and tear on parts, the energy needed to operate the press and the amount of operator oversight necessary.

The principle behind the Fournier Rotary Press TM is straightforward. Sludge is fed into a channel at low pressure that rotates between two parallel slow revolving (0.2 to 2 rpm) stainless steel filtering elements (screens).As free water passes through screens, the sludge continues to dewater as it travels around the channel.

A set of four rotary press units, each equipped with six modular dewatering chambers, were selected and delivered in 2020. Following the initial startup, the presses have been running six or seven hours, five days per …
