Industry solution
Filtration for pigments, intermediates and fine chemical solids
Fine, often coloured solids where filtrate clarity, cake washing and cloth selection decide the result.
What makes this duty different
Three constraints that shape the specification
- 01
Fine particles blind cloth and stretch cycle times.
- 02
Cake washing must be even to meet product specification.
- 03
Colour carry-over between batches contaminates product.
Fine chemical solids are slow to filter and quick to blind a cloth. The press is specified around cake washing, filtrate clarity and clean discharge, with plate material chosen for the solvent and pH in use. Closed filtrate handling and wash connections are common requirements on these lines.
Slurry conditions to confirm
Indicative ranges. Replace with the values from your process sheet.
| Typical solids content | 5 – 25 % |
|---|---|
| Particle size | 1 – 60 µm |
| pH | 2 – 12 |
| Temperature | 20 – 80 °C |
| Target cake | Washed, low residual liquor |
Recommended configuration
