Hank and Shane VanVeen of Wessuc located in Brantford, Ontario, Canada expanded their wastewater treatment and pumping services into a long-term municipal biosolids management.

When land-application of the sludge is unavailable, Wessuc turned to dewatering and composting practices. The VanVeen's tried to dewater the liquid sludge using centrifuge and belt press technologies. The equipment could not handle variances of thick and thin loads, and it wore out and choked on grit, sand, hairballs, and plastic.

Wessuc found greater success with a trailer-mounted ALAR Auto-Vac rotary vacuum drum filter. "It gives us a great competitive advantage. It uses less power, and we get very high effluent quality. The water we return to the digest contains roughly 16 to 20 mg/l of total suspended solids", says Hank VanVeen.

Wessuc, a customer of ALAR's since June 2005, has an Auto-Vac Model 6120 at their facility.
