Waterloo Biofilter
The Waterloo Biofilter ® is a patented trickle-filter type treatment system which uses an innovative filter medium to treat residential and industrial wastewater.
Waterloo Biofilter
Wastewater is sprayed intermittently onto the medium and is allowed to drain through by gravity. Organic biomass grows quickly within the medium after start-up, oxidizing organic material and nitrifying ammonia in the wastewater as it passes over the biomass layer. Because the Biofilter medium is contained in a tank it is effective under all soil or drainage conditions and substantially outperforms its nearest rival the sand filter bed. Existing facilities are treating flows of less than 1000 L/day to more than 300,000 L/day (250 to 90,000 gal/day). The Waterloo Biofilter ® is a great improvement to the conventional septic system and can have optional add-ons to remove nitrogen, phosphorus and pathogens.
The Waterloo Biofilter ® system is a single-pass aerobic biofilter designed for the biological treatment of wastewater. The patented process utilizes an absorbent synthetic filter medium designed to optimize the biological degradation of wastewater. Natural microbial action in the filter medium is enhanced by its high porosity, large available surface area, excellent air flow characteristics and ease of microbial attachment. The filter medium has optimized flow characteristics which allow for high loading rate and compact size. Allowable loading rates are typically 10 times greater than sand filters or soils. The Biofilter typically removes 90-95% BOD, 85-98% TSS, 20-50% TN and 90-99% coliform bacteria.
The compact nature of the Waterloo Biofilter ® reduces the impact of the septic system on the surrounding environment and preserves the natural landscape, waterfront, and minimizes tree-cutting.
Dense clay soils, bedrock areas, high water tables, and space limitations/lot size are domestic wastewater problems that the Waterloo Biofilter ® can easily solve.
The quality of the treated effluent is high enough that large and space-consuming traditional tile beds are not needed. Discharge of treated effluent typically can be discharged into a short shallow trench in sand or clay.
The system can be easily scaled for different sized applications (1,500 L/day to >100,000 L/day) by increasing medium depth and by adding Biofilter modules.
Benefits
Waterloo Biofilter ® is robust, compact, efficient and cost-effective.
Easy to operate, low maintenance and primarily passive.
Suitable for cold weather (-40°C) and seasonal operation.
The system is very effective for communal applications such as campgrounds, resorts, and rural sub-divisions.
Both underground and above ground configurations are available.
Functions
The system can also effectively treat industrial and municipal wastewater including but not limited to:
- on-site treatment and disposal of landfill leachate
- sewage lagoon effluent polishing
- nitrification and polishing of municipal wastewater
- food processing wastewater
- reducing BOD5 levels in industrial sewer discharges
The Waterloo Biofilter ® is a proven technology that is becoming accepted by regulators and health departments in Canada and the United States. Years of detailed monitoring of field units by independent agents have proven the system to be effective and reliable.
HDPE Tank Biofilters
Ideal for small lots, increased nitrogen removal and barging to islands & difficult access sites because of its lightweight design. The system is completely below-ground and out of sight.
Flat Bed Biofilters
Ideal for small lots, and high water table and bedrock. Minimizes tree removal on the property and the raised mounding on the property.
Cedar Shed Biofilters
Ideal for very small lots, high water table & bedrock, and preserving trees on the property. Sheds are clad in attractive stained cedar siding to blend in with a cottage setting.
Basket Biofilters
Ideal for clay soils & small lots and increased nitrogen removal. System is completely below-ground and out of sight.
Client Testimonials
"I would be happy to recommend Canadian Shield Consultants Agency and I would hire them again if the need arose."
Madeleine Nadon - Homeowner -
"In my opinion, the true test of a good business is whether or not you would use their services again. In the case of Canadian Shield Consultants Agency, Gerry and his crew, the answer is we still are using their services and we consider them our "Go To" guys!"
Wayne Johnson - Manager - YMCA-YWCA of Winnipeg
"Throughout the entire month long project CSCA did not veer from the original goal and made MRWs time in St. Charles a positive experience."
John Sikorski - Engineering Technologist - M.R. Wright and Associates Co. Ltd.
"We are very thankful for all that Gerry and his company have done for us up to now...their expertise and assistance has facilitated the process of purchasing a good quality septic system that meets the Ministry of Environment's standards."
Ms. Réjeanne de Bois - Owner - Minakwa Lodge and Trailer Park
"We were very impressed with your heavy duty machinery, and realized we were not dealing with a start-up company. All workmen on the site knew their jobs and performed all labour with such care and skill. I must add a personal comment that the workers were very amicable, answered all our questions and did not mind the interruptions when we asked for clarification as to what they were doing"
Jean McConnell - Former Manager of Recreational Arenas and Swimming Pools - City of Greater Sudbury
