Technical Specifications for KD-7 Arsenic Removal Filter Media for Industrial and Drinking Water:
1. Purification Method: Utilizes adsorption, catalysis, and ion exchange processes.
2. Operation Mode: Upflow water circulation with upflow regeneration.
3. Filtration Speed: Multi-stage series filtration, typically 3 stages, increasing stages if contamination exceeds five times the standard. Filtration speed is 3-4 m³ per hour, with a filter bed height of 1.6-2.8 meters. Optimal water purification rate per ton of filter media is 0.5 tons per hour, with a maximum of 1 ton per hour. This design allows flexibility in the exchange tower's dimensions—whether short and broad or tall and narrow.
4. Working Adsorption Capacity: 2000–3000 mg/kg.
5. Regeneration: A 7% regenerant solution is applied, with a total volume about 110% of the filter media. Slowly introduced into the exchange tower, the media is soaked for 100 minutes (no longer than 2 hours). After soaking, the solution is drained without needing rinsing, readying the media for the next cycle.
6. Bulk Density: 1.1.
7. Enhanced Filtration: Adding a chemical dosing box at the inlet improves filtration performance, extending the regeneration cycle by 5-10 times.
8. Chemical Dosing: Add either Chemical 1 or Chemical 2 at the inlet.
