Dean Trevaskis pumps and hauls commercial greasetrap, residential septic, portable toilet and wine lees near the foothills of the Sierra Nevada Mountains in Northern California.

In 1999, with several disposal sites closing or raising their discharge fees, Trevaskis opened a private processing plant to dewater over 3.5 million gallons of sludge a year.  The plant turns a profit, and Trevaskis sees a lot of potential for growth and may one day move away from pumping and concentrate solely on the processing business.

Trevaskis was excited to share what he’s learned by hosting an open house this past October (2011) in conjunction with a wastewater sysmposium held by COWA and NAWT.  Sierra Septic showcased their 12-year-old ALAR system consisting of a Rotary Auger Strainer, Super Sack Unloading System and Auto-Vac AV690 Rotary Vacuum Drum Precoat Filter.

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.
