Tooele Water Reclamation Facility Upgrade- Phase 1B
UPDATE - October 2012. Water & Wastes Digest just honored this project by naming it among its TOP PROJECTS for 2012! Congratulations to all who worked so hard on this project to make it such a success.
Alder Construction began work at the Tooele WRF in mid-2011. Construction went smoothly as Alder crews completed construction of a new 65' cast-in-place concrete sludge holding tank, a new UV disinfection building housing a new Ozonia Aquaray 3x, and numerous miscellaneous upgrades to outdated equipment and structures. The main component of this project was was the construction of the 49,000 square foot solar drying facility and new dewatering facility. This facility, the first of its kind in the United States utilizes a Huber Solar Active Dryer system that dries the sludge in a greenhouse taking full advantage of free solar energy that is so abundant in the Utah desert. This special system spreads and turns the sludge as well as transports it from one end of the greenhouse to the other. At this point, the sludge has dried to the point where it has no odor, the volume has been reduced by over 75% and is easy to handle as a soil conditioner. The reduction of solids is a huge benefit to the owner of the facility as well as the local community. Alder is very proud to have been a part of this project, adding yet another "industry first" to our resume.
According to the Huber website, “At Tooele the sludge is dried with solar power alone, this gives of course the best eco-balance. The energy consumption of the system is so low that it can be disregarded in the total cost balance.”
