LAB Filterpresses: Industrial Filtration on a Laboratory Scale

This video introduces the Autemi LAB filterpress range and explains how filterpresses perform solid-liquid separation (dewatering) by transforming a slurry into filtered liquid and a dewatered solid cake. It also provides a clear overview of the differences between the various LAB200 and LAB300 models and configurations, helping users identify the most suitable solution for their application.

Unlike simplified laboratory equipment, Autemi LAB filterpresses use the same filtration technology, options and process principles found on industrial filterpresses, allowing realistic testing and process optimization on a smaller scale. Ideal for R&D departments, universities, pilot plants and small-scale production, these systems can process batches from a few liters up to approximately 200 liters per cycle. The video also explains the importance of high-pressure feeding pumps, the factors affecting cake dryness, and the differences between stand-alone filterpresses and complete skid-mounted filtration stations. Watch this video to understand which model and configuration best fits your filtration and dewatering requirements.

LAB200-EFS – Factory Acceptance Test (FAT) Procedure

In this video, we explain the standard Factory Acceptance Test (FAT) procedure performed on our LAB200-EFS laboratory filterpresses before shipment.

The purpose of the FAT is to verify the correct operation of the machine under no-load conditions (“dry” testing) and to ensure that all mechanical, hydraulic, pneumatic and electrical components are functioning properly before delivery to the customer.

During the FAT, particular attention is given to the automatic pressure control logic of the feeding pump. The test confirms that the pump correctly starts and stops according to the pressure conditions inside the filterpress, simulating the normal behaviour that occurs during a filtration cycle as the pressure gradually increases.

The FAT also includes verification of the hydraulic closure system, pressure gauges, valves, piping, safety devices and general machine operation. Since no actual slurry is used during this procedure, the FAT is intended to validate the functionality and integrity of the equipment rather than the filtration performance itself.

This test ensures that the LAB200-EFS is delivered fully assembled, inspected and ready for commissioning, providing the customer with confidence that all machine systems operate as designed before installation and process testing.

LAB300-CEFS/TOP – General Overview

In this video, we take a general overview of the LAB300-CEFS/TOP and examine the main components that make up this advanced laboratory filtration station.

The LAB300-CEFS/TOP is not simply a laboratory filterpress, but a complete miniature filtration plant designed to reproduce, on a pilot and laboratory scale, all the main process phases typically found in industrial filterpress installations.

The station is equipped with a filterpress, an electric slurry feeding pump, a pneumatic cake washing pump, a slurry preparation tank complete with mixer, a clean water tank, and a filtrate collection tank. In addition, the unit includes a membrane squeezing system for cake compaction, a cake drying system, and a cake washing system, allowing users to evaluate and optimize the entire filtration process from start to finish.

Thanks to this comprehensive configuration, the LAB300-CEFS/TOP enables researchers, process engineers and plant designers to perform realistic pilot tests, investigate different process parameters, and generate reliable scale-up data before moving to industrial production.

Throughout this video, we will review each section of the station and explain its function within the filtration cycle, providing a complete understanding of how the system operates and how the various components interact to achieve efficient solid-liquid separation.

LAB200-PFS/TOP – Calcium Carbonate Filtration Tests

In this video, we present a series of filtration tests carried out using one of our LAB200-PFS/TOP filterpresses for the dewatering of a calcium carbonate slurry.

The objective of these tests was to evaluate the performance of different filtration configurations and, in particular, to compare standard high-pressure filtration with advanced filtration techniques incorporating membrane squeezing and cake blowing.

The results clearly demonstrate the benefits of membrane technology when combined with cake blowing. By applying additional compression to the filter cake after the filtration phase, the membrane system is able to remove a significant amount of residual liquid trapped within the cake structure. The subsequent cake blowing phase further improves the final dryness by displacing part of the remaining moisture with compressed air.

Throughout the video, it is possible to observe the differences in cake appearance, consistency and compactness obtained under the various operating conditions. The tests show the expected improvements in cake structure and handling characteristics when membrane squeezing is applied.

For this particular calcium carbonate slurry, the use of membrane technology resulted in an increase in dry solids content of approximately 6 percentage points compared with conventional high-pressure filtration alone, demonstrating the effectiveness of membrane squeezing for applications where maximum cake dryness is required.

These tests highlight how laboratory and pilot-scale filterpresses can be used to accurately evaluate process performance and determine the most suitable filtration technology before scaling up to industrial production.

LAB200-PFS – Wine Lees Filtration Test

In this video, we present a filtration test performed on wine lees using our LAB200-PFS pilot filterpress.

The objective of the test was to evaluate the dewatering performance of this challenging slurry and to demonstrate the advantages of high-pressure filtration combined with variable-flow pumping technology.

Wine lees are typically characterized by a low-compressibility solids structure, making them particularly difficult to compact during filtration. As a result, achieving high cake dryness can be challenging when conventional filtration methods are used.

Throughout the video, the filtration cycle is shown in detail, highlighting the behaviour of the slurry as pressure gradually increases and the filter cake forms inside the chambers. Particular attention is given to the operation of the variable-flow feeding pump, which continuously adapts the slurry flow rate to the filtration conditions, maximizing filtration efficiency while maintaining the required pressure profile throughout the cycle.

The test clearly demonstrates how high-pressure filtration can significantly improve the dewatering of low-compressibility slurries, while the variable-flow pumping system helps optimize cake formation and reduce the overall filtration time.

This video provides valuable insight into the filtration characteristics of wine lees and illustrates how pilot-scale testing can be used to evaluate process performance, optimize operating parameters and predict the results achievable on industrial-scale filterpress installations.

LAB200-PFS – Waste Cooking Oil Filtration Using Diatomaceous Earth

In this video, we demonstrate how a LAB200 series pilot filterpress can be successfully used to filter waste cooking oil through the use of diatomaceous earth as a filtration aid.

The test illustrates a typical process adopted to remove suspended solids and impurities from used vegetable oils before their subsequent conversion into biodiesel. Due to the characteristics of waste cooking oil, achieving efficient filtration requires a combination of proper process conditions and correct filterpress configuration.

Particular attention is given to the heating phase of the oil. By increasing the oil temperature, its viscosity is reduced, significantly improving filterability and allowing the filtration process to proceed more efficiently. The video also highlights the importance of selecting the appropriate filter cloth and filtration parameters to maximize solids retention while maintaining an acceptable filtration rate.

The diatomaceous earth acts as a filtration aid, creating a porous filtration layer capable of trapping fine suspended particles that would otherwise be difficult to remove. Through the combined action of temperature control, filtration aid dosing and optimized filtration conditions, a substantial reduction of suspended solids can be achieved.

The resulting filtered oil exhibits a significantly improved clarity and can then be used as a suitable feedstock for biodiesel production or for further refining processes, depending on the final application requirements.

This test demonstrates how pilot-scale filtration equipment can be used to develop and optimize filtration processes before industrial implementation, reducing technical risks and providing valuable process data for scale-up activities.

LAB200-TRAVEL/COMPACT – Filtration of High-Viscosity Gypsum Slurry

In this video, we demonstrate the filtration of an extremely high-viscosity gypsum-containing slurry using our entry-level LAB200-TRAVEL/COMPACT pilot filterpress combined with a variable-flow pneumatic piston pump from the HORUS range.

This application highlights the capability of the system to handle particularly difficult slurries characterized by high solids content, elevated viscosity and challenging flow behaviour. Such materials often present significant difficulties during pumping and filtration, making the correct selection of both the feeding technology and filtration equipment essential for achieving satisfactory dewatering results.

The video shows the complete filtration process, from slurry feeding through cake formation and final discharge. Particular attention is given to the performance of the HORUS pneumatic piston pump, whose variable-flow operating principle allows the filtration pressure to increase progressively while automatically adapting the flow rate to the resistance generated by the forming filter cake.

This pumping technology is particularly suitable for highly viscous slurries because it combines the ability to handle difficult materials with the capability of reaching the high pressures required for efficient filterpress operation. As filtration progresses and cake resistance increases, the pump naturally reduces flow while maintaining the pressure necessary to continue dewatering.

The test demonstrates that even the most compact LAB200-TRAVEL/COMPACT configuration can successfully process demanding industrial slurries when combined with the appropriate feeding system. The resulting filtration cycle provides valuable information regarding cake formation, filtration behaviour and achievable dewatering performance.

This video offers a practical example of how pilot-scale filtration testing can be used to evaluate the feasibility of challenging applications and to optimize process parameters before moving to industrial-scale equipment.
