In complex industrial processes, filtration is never just a mechanical operation.
It is a process-critical step that directly affects recovery, operability, chemical compatibility and long-term reliability.
Autemi designs filtration systems starting from the process, covering laboratory, pilot and industrial scale.
In sectors such as precious metals, leaching and chemical processing, filtration systems must cope with:
– aggressive or corrosive liquids
– fine, compressible or reactive solids
– variable slurry composition
– demanding operating cycles
– strict requirements on material compatibility
Standard filtration equipment often struggles to deliver stable and repeatable performance under these conditions.
Autemi supports filtration projects at every development stage:
Laboratory filterpresses are used to evaluate the filtration behaviour of the slurry under controlled conditions.
They allow the assessment of solids compressibility, cake formation, filtration rates and achievable dryness.
Different filter media, pressures and operating strategies can be tested using limited material quantities.
This phase is essential to understand whether filtration is technically feasible and which parameters drive performance.
Pilot filterpresses bridge the gap between laboratory tests and industrial operation.
They allow filtration to be tested under representative hydraulic and mechanical conditions, closer to real process constraints.
At pilot scale, cycle times, washing efficiency, cake discharge behaviour and process stability can be validated.
This step significantly reduces uncertainty when defining the industrial design and operating window.
Industrial filterpresses are engineered for long-term, repeatable and stable operation within the process.
Design focuses on mechanical robustness, material compatibility, automation logic and integration into the overall plant layout.
Operating parameters are defined based on laboratory or pilot data, not assumptions.
The result is a filtration system that delivers predictable performance over time, even in demanding chemical environments.
This approach allows filtration performance to be validated before moving to full-scale equipment, reducing technical and investment risk.
Each filtration system is engineered based on a detailed understanding of the process, including:
The origin of the slurry strongly influences its filtration behaviour.
Chemical composition, pH, temperature and the presence of reagents or dissolved metals directly affect cake formation and permeability.
In many processes, slurry characteristics are not constant but vary over time or between batches.
Understanding this variability is essential to design a filtration system that remains stable under real operating conditions.
Filtration performance depends on how solids behave under pressure.
Fine, compressible or deformable particles can lead to rapid cake compaction and declining flow rates.
The filtration mechanism must be clearly identified.
This allows correct selection of filter media, chamber geometry and operating strategy.
Maximum pressure alone does not define filtration performance.
Cycle efficiency depends on how pressure is applied over time and how the cake responds to compression.
Unrealistic pressure targets often result in marginal gains and higher mechanical stress.
Defining achievable operating pressures and cycle times ensures stable performance and protects equipment over its service life.
A filterpress must be designed as part of the process, not as an isolated machine.
Feed conditions, upstream equipment, discharge handling and downstream operations all influence filtration stability.
Layout constraints, maintenance access and operational sequencing must be considered from the start.
Proper integration improves operability, reduces downtime and avoids bottlenecks within the plant.
For applications in precious metals, leaching and chemical processing, Autemi designs filterpresses with chemically resistant wetted parts, including:
– polypropylene (PP)
– PTFE-lined components
These solutions are suitable for harsh chemical environments, where material compatibility, safety and durability are essential for continuous operation.
Autemi filtration solutions are applied in processes such as:
– leaching residues and metal recovery
– precipitation and separation of metal hydroxides
– precious and base metal processing
– recycling of metallurgical and chemical residues
– cellulose and fibrous slurries
– process water and effluent solid-liquid separation
Each application is evaluated individually, because filtration performance is always process-specific.
Autemi designs filterpresses for stable and repeatable filtration performance in demanding industrial processes.
Each machine is engineered for continuous operation, with layouts that simplify inspection, maintenance and long-term reliability.
Material selection and automation logic are defined according to the process requirements, ensuring compatibility with aggressive fluids and controlled operation.
Filtration systems are designed to fit the process, not adapted from standard configurations.
If you are evaluating a filter press for an industrial application and need a solution engineered to match your specific process requirements, Autemi can support you with a structured, engineering-driven approach.
From laboratory and pilot testing to full-scale industrial design, we help define realistic and reliable filtration solutions.
