Key Features of Volcanic Rock Products:
Volcanic rock biofilter media exhibits a unique physical microstructure characterized by a rough surface with numerous micropores. This makes it ideally suited for microbial growth and reproduction, facilitating the formation of biofilms. Volcanic rock filter media enables aeration biofilters to treat not only municipal wastewater but also biodegradable organic industrial wastewater, domestic sewage, and mildly polluted source water. It can also be used as a filter medium in water treatment, replacing materials like quartz sand, activated carbon, and anthracite. Furthermore, it can be used for advanced treatment of effluent from wastewater treatment plants after secondary treatment, achieving water quality that meets the standards for reuse. Due to its unique properties, volcanic rock is now widely used in various environmental applications, including bio-deodorization and constructed wetlands.

Advantages of volcanic rock products:
Microbial chemical stability: Volcanic rock bio-filter media is corrosion-resistant and inert, and does not participate in the biochemical reactions of biofilms in the environment. Surface charge and hydrophilicity: The surface of volcanic rock bio-filter media carries a positive charge, which promotes microbial adhesion and growth. It also has strong hydrophilicity, resulting in a large amount of biofilm and rapid adhesion. Impact on biofilm activity: As a biofilm carrier, volcanic rock bio-filter media is harmless and has no inhibitory effect on the microorganisms it supports. Practice has proven that it does not affect microbial activity. High porosity and large surface area facilitate biofilm formation and microbial growth. Cost-effective: Excellent corrosion resistance, high porosity, energy-saving and environmentally friendly, low cost, lightweight, and easy to install and disassemble.

Packaging and storage methods for volcanic rock:
Packaging: 25KG, 50KG, or ton bags (custom packaging available). Transportation: Available via truck, train, or sea freight. Storage: Avoid moisture; store in a well-ventilated, cool, and dry place.
