Applications：

The PGR Grit and Debris ®£Traveling Bridge is widely used ingrit chambers≈λ∏ &aerated grit chambers'≤ in municipal WWTPs.The trav§'&'eling bridge applies pump suction toeffectiv↑♥εely elevate grits toth≤§e waste collection trough and us↑$es vortex grit classifier to sepa-rate and di★•αscharge the grits.In situation✔≤εswhere the densityofg≠↑ritsis high,comprehensive air floatationtechnoπ≥logy is applied.
