Good Hydrophilicity: No oil adsorption, easy to absorb water, and fast settling.
High Capacity: Special wall structure with abundant biofilm capacity for synchronized nitrification.
Low Sludge Volume: Long sludge retention time and minimization of residual sludge.
The volume ratio before and after expansion is approximately 1:2.2.
Each unit is individually wrapped and placed in sturdy cardboard boxes. For larger orders, units are palletized and shrink-wrapped. We offer shipping via air, sea, or ground transportation with trusted partners.


A: PCG offers a larger surface area, better oxygen transfer, and faster biofilm growth due to its hydrophilic properties.
