12 June – Training Course: GETTING THE BEST PERFORMANCE FROM SOLID/LIQUID FILTERS

The course is a practical review of solid/liquid filtration with the aim of providing information and ideas to help you to get more out of your filtration processes. The presenters will use their extensive experience and in-depth knowledge of industrial applications to point to ways to improve the performance of filters and improve their profitability in an industrial process.

Attendance the previous day at The Solid/Liquid Separation Process is not a pre-requisite for attending this course. This course will be of interest to engineers, scientists, managers and other technical personnel involved in solid-liquid separation in the process and related industries, who will find the course informative, regardless of whether they design, purchase, research or use filtration and separation equipment. Plant engineers, technicians and operators will find the course materials directly applicable, and graduate students will value the expert introduction to the technologies.

Scope of the course:

  • Introduction – Practical and operational aspects of solid/liquid separation; overview of the course.
  • The Economic Importance of Filtration – Using case studies that illustrate the economic importance of filtration:
    • Mining/metallurgy: (i) Mineral concentrates; (ii) Alumina – residue, polishing, interaction with gravity thickening; (iii) Copper – mining (cake filtration) to electro-refining (polishing).
    • Food/biotech/pharma industries: (i) Starch – waste, product losses, environmental aspects; (ii) Pharma – API isolation and washing.
    • Other applications: TiO2 manufacturing and flue gas desulphurisation.
  • Getting Filtration Data – Obtaining necessary data to select and size solid-liquid separation equipment: laboratory tests (leaf tests, pilot scale tests, jar tests) and their relevance to process scale filters.
  • Process Optimisation – Key concepts: optimising the process and assessing the success. Considerations: cost (energy, raw material, throughput, product quality, HSE) and their quantification (including thermal drying, transportation, wash results, …). Optimising drum and disc filters: speed versus throughput, the effects of wearing parts on capacity.
  • Selection and Simulation of SLS Equipment with Computer Software – Generic equipment types, approaches to selection and simulation, use of computer software (methodology, selection charts, and data analysis) showing simple and advanced procedures.
  • Filter Operation and Filter Media Life – Operational regime, including slurry approach velocity, frequency of cloth exposure, rotational speed of drum and disc filters, filter press fill speed. Cleaning/regenerating filter media, including assessing the importance of blinding and cleaning with chemicals. Repairing filter media – patching, sewing, welding.
  • Experience from the Field – Case study focussed on optimisation and trouble shooting from a users point of view (or alternative case studies).
  • Testing and Standards for Liquid Filtration Media – Test methods and standards that apply to filter media, liquid filtration, and filter applications.

The course will be held at the National Motorcycle Museum in the West Midlands.

6 November – Conference and Exhibition: FILTER MEDIA 6

The filter medium is the critical component that determines whether a filter process will perform adequately to give the desired separation efficiency. One of the key roles of a filter medium is to create a clear separation of particulate from a fluid or gas with the minimum consumption of energy.

This one day conference and exhibition will bring together people interested in advances in new filter media that are being applied in industry. From tightening legislation to the growing number of finer, more demanding, filter processes, new filter media developments are constantly being driven by customer requirements. It has been 2 years since the last filter media one-day meeting organised by the Society. Since then new developments have taken place in media for both gas and liquid applications. This meeting will feature key elements of these developments, including the role of design of media, recent products grown from industrial R&D, and different modern filter media technologies in successful applications case studies. The continued development of filter media is key in many filtration processes and will be of particular interest to process engineers, designers, technical and R&D staff, research institutes and decision makers.
