Technical Specifications and Applications for Softening Filter Media, Bioactivated Zeolite, and Silver-Loaded Zeolite
Softening Filter Media:
Our softening filter media is ideal for use in groundwater, drinking water, hotel water, bathing water, and industrial water softening applications. It can also be used as a pre-treatment for boiler water resin softening. This media is heat-resistant and releases beneficial trace elements for the human body. It is particularly suitable for boiler water softening, combining filtration and softening capabilities. Effective in reducing water hardness from 1000 mg/L to around 40 mg/L, it offers excellent softening performance, high cost-efficiency, and simple operation. It resists interference from other ions, backwashes easily, and can filter impurities while softening the water—delivering a versatile and cost-saving solution. It is fully regenerable, restoring 100% of its functionality.
Bioactivated Zeolite:
Our bioactivated zeolite is a proactive solution in wastewater treatment, surpassing conventional activated sludge methods. It not only adsorbs suspended solids and other contaminants but also removes significant quantities of phosphorus and nitrogen. The bioactivated zeolite has an enhanced bacterial load capacity—over five times that of activated sludge—and offers 2-3 times the adsorption efficiency and removal rate.
Silver-Loaded Zeolite Filter Media:
This nano-assembled inorganic antibacterial agent is created using advanced nanotechnology to produce a fine powder with antimicrobial properties. It combines antibacterial metal ions and clusters within nano-scale pores, creating a stable, efficient, long-lasting, and broad-spectrum antimicrobial agent. Compatible with various resin emulsions, it forms a functional inorganic antimicrobial agent that enhances antibacterial activity without affecting other properties or processing.
Antibacterial Mechanism:
1. The antibacterial components interact with microbial cell surfaces or release antibacterial ions that react with essential microbial enzyme proteins (thiol -SH and amino -NH3 groups), leading to protein precipitation or deactivation, effectively halting microbial energy production and respiration.
2. Nano antibacterial components exhibit advanced catalytic abilities, producing reactive oxygen species (H₂O, H₂O⁺, O₂⁻) through interaction with water and oxygen. These active agents have potent oxidative capacity, destroying microbial cells and bio-molecules, rendering them inactive.
Performance Indicators:
- Antibacterial Efficacy: Minimum inhibitory concentration (MIC) for E. coli: 0.1% W/V, Staphylococcus aureus: 0.025% W/V; minimum bactericidal concentration (MBC) for E. coli: 0.5% W/V, Staphylococcus aureus: 1% W/V; antibacterial rate of 97% against E. coli and 95.9% against Staphylococcus aureus.
- Physical Properties: Appearance as light green or white powder; particle size distribution with 90% < 2 µm and 100% < 10 µm; average particle diameter of 0.8 µm; density of 2.75 g/cm³. It is stable and insoluble in water, acid, alkali, and organic solvents, with thermal stability. Harmful element content: Pb < 100 ppm, Hg < 0.001 ppm, As < 100 ppm.

Zinc-Loaded Zeolite Technology and Applications
Zinc-Loaded Zeolite Technology:
Zinc-loaded zeolite shares antibacterial properties with silver-loaded zeolite, though its bactericidal strength is slightly lower. However, zinc-loaded zeolite is significantly more cost-effective—up to dozens of times cheaper than silver-loaded zeolite—making it highly suitable for widespread application.
- Feed Additive Application: Zinc-loaded zeolite can be used as a feed additive for pigs, enhancing immunity and promoting growth. When combined with acetic acid and nano zinc oxide in specific ratios, it helps prevent foot-and-mouth disease in pigs.
- Coatings Application: Zinc-loaded zeolite, ground to a 300-mesh powder, can be added to coatings, forming a zinc layer that protects against mold in humid environments. This zinc-rich coating has immense application potential in metal paint.
- Paint Additive: Ultra-fine zinc-loaded zeolite powder can be added to paint, enhancing its corrosion resistance and antibacterial properties.
Water Treatment Filter Media Applications:
Our zeolite series products are widely used in various water treatment applications, including:
- Drinking Water: Effective in purifying drinking water.
- Industrial and Wastewater Treatment: Suitable for industrial wastewater and general filtration systems, such as quick filter pools, sewage filters, multi-media filters, and integrated purification systems.
- Boiler Water Softening: Ideal for softening small and medium-sized boiler water, removing calcium and magnesium ions to reduce scaling and corrosion, extending boiler life.
- Textile Wastewater Treatment: Zeolite achieves COD removal rates of 86%-92%, BOD removal rates of 99%, and color reduction of 77%-79%, thanks to its large specific surface area, strong ion exchange capabilities, and suitability for microbial attachment.
- Industrial Wastewater in Steel, Non-ferrous Metals, and Chemical Sectors: Effective in removing phosphorus, lead, and hexavalent chromium. Deactivated zeolite can be regenerated with concentrated saline backwash for reuse, making it cost-effective and efficient.
Zeolite also removes turbidity, color, odor, and heavy metals (e.g., chromium, cadmium, nickel, zinc, mercury, iron ions) and organic pollutants such as phenols, nitrogen compounds, ammonia, and phosphate ions. Its adsorption-exchange properties are particularly effective for reducing micro-pollutants in water without leaching toxic substances, offering superior removal of iron, manganese, fluoride, arsenic compounds, and ammonia nitrogen.
Our company follows a high-tech, pollution-free development strategy, leveraging rich natural non-metallic mineral resources. We collaborate with institutions like Harbin Institute of Technology, Tongji University, and the Chinese Academy of Agricultural Sciences to create nationally promoted eco-friendly materials for water purification, wastewater treatment, air pollution control, health-focused air products, soil improvement, and heavy metal soil remediation.
