Unlike disposable filters (service life 1-2 weeks), it is reusable and corrosion-resistant, with service life up to 2-5 years. It achieves filtration precision from 1μm to 200μm and handles flow rates up to 50m³/h, complying with FDA 21 CFR Part 177 for food contact, suitable for water treatment, food processing, and pharmaceuticals.
High Filtration Precision: Precision ranges from 1μm to 200μm with ±5% tolerance, achieved via laser drilling or electroforming. The 1μm variant removes 99.9% of 2μm+ particles (water treatment), while 200μm suits industrial wastewater pre-filtration.
In-To-Out Flow Design: Filter cake accumulates on the inner surface, enabling backwashing (10-20 bar) to restore 95% of initial flow. A food plant reduced filter replacement costs by 80% vs. disposable cartridge filters.
Corrosion & Temperature Resistance: 316L stainless steel resists acids (pH 2-13) and oils, with corrosion rate < 0.01mm/year; 304 stainless steel for neutral media (pH 5-9). Operates stably at -20°C to 200°C—suitable for hot beverage filtration (100°C).
High Flow Capacity: Open area up to 50% of total surface, minimizing pressure drop to < 0.2MPa. A 100μm filter achieved 30m³/h flow in a brewery, increasing production efficiency by 25% vs. standard filters.
Water Treatment: Drinking water and wastewater filtration. A municipal water plant used 5μm 316L filters, removing 99% of sediments and bacteria—tap water turbidity reduced from 5 NTU to 0.5 NTU (meets WHO standards).
Food & Beverage: Juice and beer clarification. A Brazilian juice plant adopted 20μm in-to-out filters, removing pulp and particles while retaining nutrients—juice clarity increased by 40% and shelf life extended by 7 days.
Pharmaceuticals: Sterile filtration of drug solutions. An Indian pharmaceutical company used 1μm electroformed filters, achieving USP <788> compliance (99.99% particle removal) and reducing product rejection rate by 5%.
Q: Which material fits acidic liquids (pH 3)?
A: 316L stainless steel is ideal, with corrosion rate <0.01mm/year. 304 stainless steel corrodes at 0.1mm/year in pH 3 media, failing in 6-12 months. For strong acids (pH <2), use Hastelloy C276 (cost 3x 316L).
Q: How often to backwash the filter?
A: Backwash when pressure drop reaches 0.2MPa (typically every 1-2 weeks). For high-sediment media (e.g., river water), backwash weekly; for clear liquids (e.g., drinking water), every 2 weeks. Backwashing takes 5-10 minutes.
Q: Can it handle high-viscosity liquids (e.g., syrup)?
A: Yes, choose 50-200μm precision and increase backwashing frequency to every 3-5 days. The in-to-out design prevents viscosity-related clogging—flow rate for syrup (1000 cP) is 10m³/h (half of water, but stable).
Q: What’s the maximum operating temperature?
A: 316L stainless steel filters operate up to 200°C; 304 up to 150°C. For higher temperatures (200-300°C), use Inconel 625 filters (cost 4x 316L). Avoid temperatures above 200°C for 316L—causes material fatigue.
