Biological Filtration Done Right!
Robin’s Nest is a leader in Biological Filtration in New England. Their 25 years of experience, hard work, and intuitive design and engineering will leave you with a smile on your face and enjoying every moment next to, in, and around your new water garden, swim pond or natural waterfall.
Pond Biological Filtration (Bio-Filtration) uses a pump, plants filter area and usually a waterfall return to filter and aerate existing or new earthen or lined ponds. Some refer to it as a sort of bog filter.
Using an energy efficient pump, proper plumbing, and native plant and stone material, a client can expect something very functional and beautiful at the same time. We like to think of it as a reward to the client for doing the right thing for his property, water and the environment.
Bio Filter Construction
Constructed bio-filters, often referred to as bog filters are very similar to leach fields for septic systems, with a few exceptions:
- Bio-filters are open on top and planted heavily with filtering plants.
- Bio-filters pump water from the pond, through the filter, and returning back to the pond via a man made water fall and/or brook.
- Beneficial bacteria are introduced to substantially reduce organic matter and break it down.
- Cleaning the filter is done by thinning the plants and back-washing it annually.
