12mm 19mm pitch Nitrifying bacteria culture honeycomb filter block

waste water treatment Biological Block PVC filter block is a modular PVC corrugated media that is specifically designed for fixed film biological treatment applications. With a minimum void to volume ratio of 95%, PVC filter block allows for uniform redistribution of wastewater and air while maximizing contact between the biomass and the wastewater. PVC filter modules are composed of thermoformed PVC sheets that are UV protected and resistant to rot, fungi, bacteria, acids, and alkalines commonly found in wastewater. The PVC compound is non-toxic to microorganisms and specifically formulated to resist long-term creep and cracking under continuous loading. Available in cross flow (XF) and vertical flow (VF) designs, Lanyu PVC filter media includes a full range of modular PVC media geometries for wastewater treatment including complete secondary treatment, nitrification, denitrification, industrial roughing filters, submerged fixed beds and anaerobic treatment systems.

PVC sheet media for trickling filters, submerged fixed beds, and other wastewater treatment applications including oil/water separators. This is a self-supporting PVC sheet media capable of withstanding loads in excess of industry standards. 0.25mm-0.5 Thermoformed PVC sheets Non-toxic to microorganisms and immune to rot Resistant to degradation by UV light, fungi, bases, acids and other wastewater compounds
