Substance filtered out: calcium sulfate; Temperature: 95–100°C; pH: 3–9; Filtration using ordinary fast-filter paper in the laboratory does not result in leakage; the manufacturer stated that the pore size of such paper is 30–50 μm. In production, filter bags made of 750B filter fabric were found to have leakage issues. Questions: 1. Recommendation for an appropriate filter cloth selection; 2. What is the pore size of the 750B and 750A filter cloths?
