The Country Pond Filter is a biological system that will help reduce nutrients in your pond. Nutrients that impact water quality may enter your pond from external sources like fertilizer runoff and when organic materials on the bottom are re-suspended or digested by microbial action.
• No excavation is needed if a level pond bank is available.
• The recirculation pump for the filter uses less than 100 watts of electricity.
• This process removes nutrients during winter conditions when other biological products and shallow water plants are dormant.
• Filter components for a half acre pond are packaged in a box and can be easily assembled.
• Larger filters can be constructed by increasing the liner size and media volume.
The Country Pond Filter uses an active media material that supports the growth of select unicellular algae after inoculation. When pond water is pumped into the filter basin it slowly flows across the media and then returns to the pond. This allows direct completion for phosphorus, nitrate and other trace nutrients during the recirculation process.
The size of a filter is determined by calculating the surface acreage of the pond and measuring the amount of nutrients that are in the water. Filters up to one acre in size can be constructed with one piece of liner material. If additional filtration is required, units can be connected or positioned where needed.
Our research work and field observations support the idea that all aquatic plants and animals are subject to some form of competition for nutrients. If a particular organism is more adept at using nutrients like phosphorous or nitrogen, it will prosper and possibly dominate the aquatic environment. Think about zebra mussels or duckweed. We worked with a university graduate program to identify and select types of unicellular algae that could be used to compete for nutrients at the most elementary level. After this work was accomplished we focused on testing submersible pumps and selecting suitable materials for constructing basins. One goal that drove our research was how to make a filter without needing to bring excavation equipment to the site. We figured out how supply our customers with the components to make a filter for a pond up to one half acre that can be cost effectively shipped in a box. We have been building filter for more than twenty years now and are still finding ways to make improvements.
