KD-6 Ammonia Nitrogen Removal Filter Media Specifications:
(1) Purification Method: Adsorption, catalysis, biological regeneration, and ion exchange.
(2) Operation: Upward water flow and upward regeneration.
(3) Filtration Speed: 5 m/hour; media layer height of 1.6 m or more, with a maximum of 2.8 m.
(4) Maximum Operating Range: 10,000 mg/L.
(5) Working Adsorption Capacity: 25,000-35,000 mg/L, depending on initial water concentration, interfering ions in the water, and pH level. Higher initial water concentration increases adsorption capacity; greater interference from coexisting ions reduces performance.
(6) Regeneration: 10% saline solution, with a solution volume approximately 1.2 times the media volume. Inject into the exchange tower, soak for 4 hours, then discharge.
(7) This is the purification method for drinking water; for industrial use, reference can be made to quartz sand and manganese sand.
II. Long-Term Ammonia Nitrogen Removal Media Usage
KD-6 Long-Term Effective Ammonia Nitrogen Removal Media Specifications:
1. Working Method: Adsorption, exchange, membrane decomposition, and biological regeneration.
2. Operation: Upward water flow and upward regeneration.
3. Filtration Speed: Dosage based on 40-60% of the hourly filtered water volume.
4. Maximum Operating Range: 5000 mg/L.
5. Working Adsorption Capacity: Unlimited.
6. Operating Cost: Zero; easy to use and effective for over 5 years.
7. Aeration Equipment: Installed before the filter tank or pool; aeration level adjusted according to ammonia nitrogen concentration.
8. Optimal Working Temperature: Above 20°C; efficiency decreases below 5°C.
9. Regeneration: Not required.
KD-5 Heavy Metal Removal Filter Media Specifications
(1) Bulk Density: 1.1. Purification Method: Adsorption, catalysis, and ion exchange.
(2) Operation: Upward water flow and upward regeneration. Filtration speed: 4-8 m/hour, adjusted based on heavy metal concentration. For 1 mg/L iron and 0.4 mg/L manganese, use a filtration speed of 7 m/hour.
(3) Media Layer Height: 1.5 m or more, with a maximum of 2.8 m. For concentrations above 3 mg/L, multi-stage treatment is recommended.
(4) Working Adsorption Capacity: 25,000-30,000 mg/L, depending on ① initial water concentration ② interference from coexisting ions ③ pH level. Higher initial water concentration increases adsorption capacity; more interfering ions reduce efficiency. Optimal pH range is 7-9, with higher adsorption at higher pH levels within this range.
(5) Regeneration: Soak in a saturated saline solution for 4 hours, then discharge the solution before resuming operation.
Water Treatment Filter Media Applications
Our series of activated modified zeolite filter media products are widely used in drinking water, industrial process water, industrial wastewater, and various filtration systems, including quick filter pools, sewage filters, mechanical filters, multi-media filters, and integrated water purifiers.
For small and medium-sized boiler water softening, it effectively removes calcium and magnesium ions, reducing scale formation in boilers and extending boiler life.
Using activated zeolite as filter media, it can achieve a COD removal rate of 86%-92%, BOD removal rate of 99%, and color removal rate of 77%-79% in textile wastewater, due to its larger specific surface area compared to sand media, high ion exchange capacity, and suitability for microbial attachment. The media facilitates the conversion of NH4+ to nitrate by promoting the growth of nitrifying bacteria.
In steel, non-ferrous metal, chemical, and other industries, it can remove phosphorus, lead, and hexavalent chromium from industrial wastewater. Used zeolite can be regenerated using concentrated saline reverse flow for reuse. It effectively removes turbidity, color, and odors, and adsorbs and exchanges harmful heavy metals (e.g., chromium, cadmium, nickel, lead, zinc, mercury, iron ions) and organic substances (e.g., phenols, nitrogen compounds, ammonia nitrogen, phosphate ions), enabling the removal of micro-pollutants without toxic leaching, providing notable removal efficacy for iron, manganese, fluoride, arsenic, and ammonia nitrogen in water.
Corporate Commitment
Our company follows a high-tech, pollution-free development strategy, utilizing rich natural non-metallic mineral resources. In partnership with institutions such as Harbin Institute of Technology, Tongji University, and the Chinese Academy of Agricultural Sciences, we are committed to developing environmentally friendly materials for drinking water purification, wastewater treatment, air pollution control, health-related air products, soil improvement, and remediation of heavy metal contamination in soil, earning recognition as a nationally prioritized eco-friendly material provider.
