10. FAQ: Technical Terms Explained
- Q1: What is the meaning of mesh size (100/200/325 mesh) in diatomite powder?
- A: Mesh size indicates the number of openings per inch in a sieve through which the particle passes. 325 mesh diatomite has finer particles (~44μm) suited for high-clarity filtration, while 100 mesh (~125μm) is used for coarse filtering or filler.
- Q2: What is SiO₂ content and why is it critical?
- A: SiO₂ (Silicon Dioxide) is the main component of diatomite, providing chemical inertness and filtration porosity; higher values (≥91%) ensure better purity and stable performance.
- Q3: What are typical application standards for diatomite earth in water filtration?
- A: Applicable standards include ANSI/AWWA B603 for potable water, EN 12902 for chemical filtration, and FDA (21 CFR 182.1400) for food-contact safety.
- Q4: How does diatomite compare with perlite filter aid?
- A: Diatomite offers higher micro-porosity and finer particle retention (down to 2μm), vs. perlite's 4–10μm range. Diatomite is preferred in pharmaceutical and beverage clarity.
- Q5: What is the expected service life of diatomite filters?
- A: With proper operation (backwashing, replacement cycles), diatomite filter media can be used up to 12–18 filtration cycles before requiring a full recharge.
- Q6: Are there any special storage requirements?
- A: Store in dry, ventilated areas in sealed, moisture-proof packaging; avoid direct sunlight to preserve granularity and performance.
- Q7: How is product batch consistency ensured?
- A: Every batch is sampled and tested according to ISO 3262-22 and EN 12913 for particle size, SiO₂ content, and impurity levels; results and certification are included with shipments.
