Title: Denitrification delivery channel in activated sludge treatment plant - empties waste-water into one of several aeration basins, using quick-opening penstock
Inventor: GROENEWEG JOOST
IPC: C02F1/00
Filed: 1991-05-24
Abstract: In activated sludge plant, esp. one with denitrification, a number of aeration basins are fed with wastewater from a common horizontal delivery main or channel located above the top water level in the basins.
