Dagaz Environmental - Surface Water Management Services
For 26 years, the Little River Pond Mill® circulators having been assisting in the improvement of surface waters including dugouts, lakes and ponds. Eutrophic lakes and other surface waters suffer from high nutrient and carbon loading, high primary productivity, and in many cases oxygen deprivation, the growth or excessive growth of undesirable/harmful organisms, and other undesirable characteristics. The Little River Pond Mill® circulator floats on the surface of the water and becomes an effective ecosystem management tool that addresses many issues of proper surface water management which include the reduction or elimination of odours, BOD (biological oxygen demand or biochemical oxygen demand), COD (chemical oxygen demand), TSS (total suspended solids or suspended solids), pollutants, algal and milfoil blooms, and the increase of DO (dissolved oxygen), organism diversity and competition, etc.
Services Details
The circulator action encourages the organisms, producers and consumers, in the aquatic environment (lake, pond, sewage lagoon) to increase their overall productivity (biostimulation). The introduction of oxygen, at the atmosphere (air)-water interface, in conjunction with the powerful circulation, provides an environment that enhances or improves the natural diversity in the aquatic system by upscaling the rate and the efficiency of the naturally occurring biogeochemical cycle (the rate and the efficiency at which energy, nutrients, oxygen, etc. are cycled).
With the addition of the Little River Pond Mill® circulator, the ecosystem is now more balanced meaning that the organisms within the aquatic environment are now synchronized with the nutrients, oxygen, energy and circulation available to them and 'excesses', i.e. algae bloom, odours, etc., should no longer pose a problem.
Prior to the introduction of circulation and surface re-aeration, using the Little River Pond Mill® circulator, nutrient rich organic matter settled to the bottom where anaerobic decomposition took over. Anaerobic decomposition produces potentially toxic and foul-smelling gases - both undesirable and potentially lethal to people, other organisms, and to our atmosphere. Some of the byproducts of anaerobic decomposition also prevent or deter the growth of the more sensitive, yet desirable, fish, mammal, and other animal (vertebrate and non-vertebrate) species.
The circulation and aeration component introduced not only allows more organisms to survive in the same amount of space, and promotes the creation of crucial biofloc and biofilm microbial communities, but it also promotes an increase in both species diversity and population density. This ecosystem enhancement reduces the negative components typically observed in stagnant aquatic ecosystems.
Some of the observed benefits include a reduction/elimination of/in:
- noxious odours and potentially harmful gases (including greenhouse and acid rain gases)
- biological (BOD) and chemical (COD) oxygen demands
- suspended solids
- pest/undesirable/harmful weed and organism species (Eurasian Watermilfoil, mosquito larvae, e.coli)
- pollutants (hydrocarbons)
Various factors are working together to create the improved ecosystem effects. These factors include the presence of circulation, competition for food, predation, the presence of oxygen, elimination of a desired habitat, tying up of a required nutrient element(s), exposure to sunlight (UV rays), and other factors (known/unknown).
The Little River Pond Mill® circulator is an effective ecosystem enhancement tool that can be used to 'tailor-make' solutions in surface water. Whether your desire is to enhance or maintain fish populations in a lake, increase the survival rate and health of shrimp in a pond, or clean up a polluted aquatic environment, the Little River Pond Mill® circulator is an effective tool in aquatic environment management.
