METEOR

Wastewater treatment systems in the nature of biofilm carriers comprised of high-density polyethylene cylinders that circulate freely in activated sludge for bod reduction, nitrification, denitrification, or total nitrogen removal, used in a wastewater treatment system

Wastewater treatment systems, namely, plastic water purification units providing high surface area to volume ratio for the purpose of high-density biofilm growth, operating in wastewater treatment tanks
