Often treatment of water bodies is directed at eradicating a symptomatic condition (e.g. eliminate unsightly algae).  Frequently, this is by chemical means and no attempt is made to address the underlying cause of the eutrophic condition which prompted the problem situation to develop in the first place. Penergetic w works to naturally re-establish the ecological equilibrium in an aquatic environment in order to return it to a healthy state, so that any previous detrimental conditions are overcome and avoided in the future.

In some cases it has taken a pond, dugout or lake years to reach the “tipping over” point – meaning the point where eutrophication sets in and it is no longer able to support itself in a natural balance.  Each situation is unique.  In some cases, it will also take time for the water body to re-establish itself – realistic expectations are warranted.

Factors that may potentially influence the effectiveness of penergetic w

  • Water body already in a highly advanced stage of eutrophication
  • Sludge (including organic matter on bottom) exceeds 50% of total volume of water body
  • Uncontrolled exposure to nutrients from an external source (e.g. runoff from fertilizer application, animal wastes or other sources)
  • The complete absence of aquatic plants in the littoral shore zone (upper 2 metres) of the water body
  • If treatment is initiated during summer period of stagnation after water body circulation has been stratified

PRODUCT FORM - Product Type

Penergetic w for water remediation is available in three different forms, serving three specific purposes:

A) Penergetic w for surface water / stabilization

  • Re-establishes oxygenation and pond microorganism activity
  • use during vegetation phase at water temperature above 8'C
  • best applied in the Spring / early Summer, when full water layer circulation/mixing evident

B) Penergetic w for waste water / mud reduction

  • promotes natural decomposition of organic material
    (e.g. bottom debris)
  • provides aquatic resource with self-cleaning capabiilities
  • use during vegetation phase when water temperature is not more than 12'C
  • best applied in early Spring or in the Autumn – once full water layer circulation/mixing is re-established

C) Penergetic w for groundwater

  • for wells and cisterns
  • can be applied at any time
  • may be used in conjunction with AquaKat for water vitalization


Applied between Spring and Autumn
Initial application (based on surface area)

up to 10 m²   (110 sq. ft.) 5.0g/m²
up to 100 m²   (1,100 sq. ft.) 3.0g/m²
up to 1000 m²   (11,000 sq. ft.) 2.0g/m²
up to 2000 m²   (22,000 sq. ft.)  1.5g/m²
over 2000 m²   (22,000 sq. ft.) 1.0g/m²

Subsequent Applications

Use 1.0 g per m² for all further applications

Volume Based Application Measurement
In cases where the average depth of the water body is >2.0 m and there is little or no vegetation in the littoral (shore) zone, an application rate based on the volume (m3) may be more suitable to use.

Frequency of Use
Following the initial application, subsequent applications should be every 3 to 4 weeks until the water body stabilizes.

Other Tips

  • following a heavy rain, top up dosage by 1g/m²
  • in hot weather reduce time between applications.
  • self-cleaning process can be accelerated by pouring a bucket of water and sediment from a healthy pond into the water to be treated.


Surface Water Treatment

Treatment should be carried out according to the time of year and the specific problem to be addressed.  The initial dose should be applied as specified above. To more precisely calculate the dosage refer to the penergetic w logarithmic table (dosage to water surface area).  If treatment with penergetic w (for surface water), at the normal application rate, does not reduce algae to normal levels, penergetic w (for mud reduction) can also be used as a supplementary agent.

Sludge Deposits

In mid-Autumn (October to beginning of November – depending on location) the water should be treated with 2 g of penergetic w (for mud reduction) per m².**  Sludge and accumulated organic matter in natural bodies of water are broken down naturally at the lower temperatures which prevail during the cooler time of the year (including over the winter).  Treatment with penergetic w (for mud reduction) will result in the accumulated biomass to be processed more quickly and the sludge broken down.  Then in the Spring, treat with penergetic w for surface water every 2 to 4 weeks should commence.

** Warning: Caution should be exercised in using penergetic w (for mud reduction) in water containing fish.  If fish are raised for food and are to be harvested, they should be removed before using “w” for mud reduction. However, if at the owner’s discretion it is decided to use penergetic w (for mud reduction) with fish in the water body, in order to reduce organic matter content, it should be used at a reduced dosage of  0.5 g/m².  A higher dosage may lead to an oxygen deficiency for the fish as a result of the stimulated sludge breakdown process, especially if a hot spell occurs.  [Penergetic w (for surface water) is save, even beneficial, for fish as it acts as a catalyst increasing the water’s oxygen supply.]

Additional Support for Water Remediation (for Larger Bodies of Water)

For larger bodies of water – with a surface area greater than 1.0 ha (2.5 acres) the aquatic regenerative effects of penergetic w may be supplemented by using a submersible XXLarge AquaKat® specifically designed for water remediation.  In some cases, a Penergetic Water Module (or water unit) – containing two XXL AquaKats in it – may be used instead.  This is a more powerful form of treatment than the single XXL AquaKat.  Should an XXLarge AquaKat® or water unit be used the calculated quantity of penergetic w powder(s) may be reduced (by up to 50%).

Furthermore, in specialized situations – where there is a particular aquatic condition needing to be addressed – Penergetic can custom-design an application to re-balance the water body’s ecology.  For more details on the applicability of the XXLarge AquaKat, water module and customized approaches to water remediation contact Penergetic Canada directly.



Practical Example: Lake Bad Balyersoien, Bavaria, Germany

Size: 200,000 m2 (50 acres) part in a nature reserve

Nature of Problem: Excessive plant growth in the lake, unaesthetic appearance & hazardous for swimmers.

History of past attempts at eradication: A boat mounted mower was used to cut the aquatic plant/weeds in the lake and the Village contracted to have a swimming channel dredged through the weed growth in the lake.  Very expensive and the problem always returned.

Penergetic Solution:  Two (2) AquaKat water modules and 160 kg of penergetic w per year.

Result:  Lake regained its natural ecological balance. Plant growth in the lake is now controlled naturally. The Village and swimmers are both happy.  The focus has now shifted to treating upland sources of nutrient loading with other penergetic products.


Groundwater Treatment

Water wells, springs, cisterns and drinking water reservoirs can often lack a self cleaning ability to  biologically-convert various potentially-contaminating substances; in which case they can be characterized by:

  • Poor water quality
  • Nutrient contamination (i.e. ammonium, nitrite, nitrate)
  • Presence of iron or manganese
  • Contaminated with harmful bacteria
  • Lack vitality

Penergetic w (for groundwater):

  • vitalizes groundwater
  • supports the natural decomposition and self-cleaning capacities in the groundwater
  • biologically stabilizes the water supply
  • activates the natural life processes in the water
  • assists in metabolizing various nutrients and contaminants in the water
  • addresses issues related to nitrogen build-up

** For maximum effectiveness where water is to be used for domestic water supply, for livestock or other uses requiring a high quality of water, penergetic w (for groundwater) should be used in conjunction with an AquaKat®.

Application Rates: depended on the nature and type of water source, volume of usage and initial versus subsequent rates of application.  Contact your Penergetic distributor for details.

Wastewater Treatment

Due to the presence of an anaerobic condition in the system and an inability of the wastewater to establish its own self cleaning capacity, sewage lagoon and sewage treatment facilities can often have problems associated with: odours, excessively high BOD and COD values, low microbial activity, poor treatment efficiency, high sewage processing costs, sedimentation build-up, poor aesthetic appearance and standard level of quality of effluent for submission into receiving waters.

Penergetic w (for waste water):

  • supports the natural decomposition and self-cleaning capacity in sewage
  • stimulates an aerobic process and activation of microorganisms
  • reduces the quantity of organic matter and nutrients
  • moderates and controls BOD and COD levels
  • stabilizes the system’s microbiology
  • curtails odour occurrences
  • creates a more homogenous wastewater

**   In addition to municipal (local government) systems, the penergetic approach to wastewater treatment can also be used in commercial or industrial settings where there is a lagoon or wastewater stream requiring treatment. 
**   Can also be used in toilet systems (e.g. parks, rest areas, recreational property) to reduce odour and activate decomposition process.
