Retrofit lagoons or aeration technologies with a Waterloo Biofilter to improve system performance
Retrofitting lagoons that are underperforming or at-capacity, and failing aerobic treatment units with a Waterloo Biofilter system is a cost effective way of meeting effluent limit criteria without the need for total system replacement. Pre-treated effluent such as that from lagoon or ‘suspended sludge’ systems can be loaded at very high rates to a Waterloo Biofilter treatment unit due to the lower organic and suspended solids loading.
Waterloo Biofilter treatment units can be configured to reduce the stress on existing systems by receiving a portion of the pre-treated effluent and recirculating it back into the system headworks. The Waterloo Biofilter can also be installed as the final component of the treatment train, intercepting and polishing all pre-treated wastewater prior to disposal.
The Waterloo Biofilter technology is very compact, robust, and contains few moving parts. Our filtration medium has the highest surface area-to-volume ratio of any attached growth trickling filter media used in the industry. Retrofitting existing wastewater treatment plants with a Waterloo Biofilter system is a cost effective way of improving treatment levels and extending the service life of existing onsite systems.
Our experienced design staff will take into account the daily flow rates, pre-treated effluent characteristics, desired final effluent criteria, and the site characteristics when designing a polishing system that will rejuvenate old or failed decentralized wastewater systems with minimal site disturbance required.
