Presentation: Municipal Lagoons – Wastewater into Revenue
Presenter: Peter Christou, President & Founder
~ Abstract ~
Municipal wastewater treatment facilities around the world are facing challenges with respect to capacity, structural integrity, and environmental compliance due to aging infrastructure, population growth, increasingly obsolete technologies, and external factors. In Alberta alone, more than 400 lagoons will require upgrades or repairs within the next 5 years. The conventional lagoon upgrade devices, including mixers, aerators, and biofilm units, are typically marred by high CAPEX, inconsistent effluent quality, and/or high footprint.
The Swirltex Lagoon Unit (SLU) is a portable, housed unit that consists of a micro-diffuser and a tubular membrane. Wastewater contaminants are encapsulated in air, increasing their buoyancy, while the centrifugal force of the vortex flow in the membrane tubes ensures the contaminants are contained in the centre of the membrane. This greatly reduces fouling, maintenance costs, and down-time. Another advantage of the SLU is the recovery of a clean effluent stream, which can be sold to industry to offset their fresh water consumption. The air and flow pattern also serve to mix and hyper-oxygenate the wastewater, enchaining bacterial activity of the stream returning to the lagoon.
Swirltex has demonstrated the efficacy of its technology in multiple field demonstrations, two of which in Alberta. In these demonstrations, the SLU exceeded expectations in terms of TSS and BOD removal, as well as power consumption.
Swirltex would like to partner with Albertan municipalities whose lagoons are at capacity, struggling to meet environmental regulations, or where water is an increasingly scarce resource. The partnership would be low-risk to the community, as Swirltex assumes full responsibility for the maintenance and operation of its units, and charges per volume of treated wastewater rather than the cost of an entire SLU. Swirltex is poised to deliver long-term value in its communities of practice, by triggering economic development through wastewater re-use opportunities, and collaborating with educational institutions to develop lagoon operator courses. Swirltex takes great pride in the fact that its technology reduces wastewater discharge into the environment, reduces water diversion from sensitive ecosystems, and promotes water re-use in a world where water is an increasingly scarce resource.
