Headworks Packaged System (H-PAC®)

Lakeside’s H-PAC® system combines our Raptor® or Hydronic T Screening product line with our SpiraGrit Vortex Grit Chamber in an elevated pre-engineered headworks system. The modular design allows you to choose the proper Raptor® Screen for your application. The Raptor® Screen will remove, wash, compact and dewater the captured screenings and the SpiraGrit Vortex Grit Chamber will remove grit in a mechanically induced vortex environment. The Hydronic T Screen is also available for screenings removal with cost savings at higher flow rates. The H-PAC®’s self-contained system is capable of handling flows as high as 12 mgd. With its compact design the H-PAC® requires less space and costs less than other packaged screen/grit systems.
