Abstract:Treating sewage on-site at commercial sites is challenging due to presence of high-strength organics and use of chemical cleaners. When the treated sewage is reused immediately for toilets or truck washing, excellent treatment must occur and it must be sustainable. Designs and operational data for two busy truck stops are presented that incorporate exterior grease traps, septic tanks, absorbent trickle filter aeration, and UV disinfection. A ‘dead-end’ tank for off-site treatment of anti-septic chemicals is used at one site to ease treatment, and filtration-ozonation and chlorine addition is used at the other site for colour removal and interior dual plumbing. Analytical results of both facilities are well within regulatory objectives, including colour and odour aesthetics, enabling regulatory agencies to decrease monitoring costs and encourage more reuse.
