Wastewater Management

Remediation of Waste Water


For 23 years, the Little River Pond Mill® circulators having been assisting in the improvement of waste water systems globally by enhancing both biological and natural chemical processes in aquatic (water based) environments (biostimulation).

One of the primary problems associated with wastewater reservoirs and holding facilities is the excess of one or more nutrients, and/ or other chemicals, causing an imbalance within the system. Anoxia, or low to no oxygen status, is typical within this unbalanced state. These conditions, combined with potential environmental toxins, create pollution/ toxic waste or a pollution/ hazardous waste hazard.

The Little River Pond Mill® circulator floats on the surface of the wastewater and addresses many of the issues of proper waste water management which include the reduction or elimination of odours, biological oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS), pollutants, alga and cyanobacteria blooms; and the increase of dissolved oxygen, organism diversity and competition, and breakdown of organic and synthetic substances.

Prior to the introduction of circulation and surface re-aeration, using the Little River Pond Mill® circulator, primarily anaerobic decomposition took place. Anaerobic decomposition produces potentially toxic and foul-smelling gases - both undesirable and potentially lethal to people, other organisms, and to our atmosphere.

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 including such as waste water lagoons.

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 organisms (e.coli)
  • pollutants (hydrocarbons)
  • chemical use/quantity of chemical required
  • energy consumption to treat waste water and liquid effluent
  • recalcitrant xenobiotic substances (exact nature of breakdown conditions has yet to be scientifically documented)

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)
  • changes in chemistry (e.g. pH)
  • 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 aquatic environments such as waste water lagoons.  Whether your desire is to reduce or eliminate odours and solids in a waste water lagoon, or clean up a hydrocarbon contaminated aquatic environment, the Little River Pond Mill® circulator is an effective tool in aquatic environment management.

Wastewater Management Conclusions


The circulation action, combined with the passive and active aeration and UV exposure, promoted by the Little River Pond Mill® circulator, helps to create a healthier aquatic environment. This effective aquatic ecosystem management tool is both efficient and economical in reducing the effects of pollution in a world where waste and mismanagement have unfortunately become acceptable practice.

The benefits of the biogeochemical cycling process and the highly efficient circulation created by the Little River Pond Mill® circulator can be seen in such parameters as:

  1. Reduction of potentially toxic and/or harmful odorous and nonodorous gases
    • improve human safety
    • improve environmental safety
  2. Reduction in BOD, COD, SS, turbidity
    • improves the functionality and life span of the waste water pond
    • potentially reduces the cost of any secondary treatment requirements
  3. Increase biotic species diversity and population densities
    • improves the treatment process
  4. Reduction in the growth of pest/harmful/toxic aquatic species (e.g. e.coli)
    • improve human safety
    • improve environmental safety
    • potentially reduces the cost of any secondary treatment requirements
  5. Reduction in nutrient availability
    • improve environmental safety
    • potentially reduces the cost of any secondary treatment requirements
  6. Highly efficient circulation component
    • reduced energy consumption when compared with other circulators
    • reduced requirement for chemicals, when chemicals are required in secondary treatment, due to increased exposure potential
    • reduced secondary treatment costs due to reduced energy requirement and more efficient chemical use

The environmentally friendly remediation of surface waters (aquatic ecosystems) through use of the Little River Pond Mill® circulator, a biogeochemical cycle remediation facilitator and effective aquatic ecosystem enhancement and management tool, provides many benefits.  It provides environmental, economic, and social benefits to the environment, the industrial/commercial producer of the wastewater, and the surrounding community. It can reduce environmental, economic, and social costs associated with waste water management.
