The Waterloo Biofilter
system is a compact, reliable and low maintenance
septic system, fully approved in Massachusetts.
While conventional septic systems use a tile bed to treat and dispose of septic tank effluent, the Waterloo Biofilter system uses a highly efficient, patented filter medium to provide a consistent and high level of treatment making disposal in the soil easy.
This system is especially effective for difficult sites such as small lots, heavy clay soils, shallow or exposed bedrock, and high water table, such as the New England coastal areas.
HOW DOES IT WORK?
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 90-98% BOD, 90-99% TSS, 50-60% TN and 98-99% coliform bacteria.
