Frequently Asked Questions

Questions about our products & services help NUVAC focus on specific details.  Please, don't hesitate to submit your questions, our team will be happy to find the right answers.   


What are the regulations for your products? 

Nuvac's products are not controlled under the MDDEP or certified by the BNQ as only wastewater treatment systems, such as aerated ponds & residential systems, are certified & controlled.  However, our products' formulations comply with Environment Canada's Domestic Substances List (DSL). In fact, Canadian manufacturers making products with microorganisms must use strains of microorganisms that have been tested & confirmed as non-pathogenic and safe for humans, wildlife & the environment.  


Do your bacteria affect the piping system (cement, PVC, copper, etc.)? 

Bacteria in our products do not attack inorganic material, such as plastic and products made with mineral material.  Nuvac's bacteria only degrade organic matter such as human or animal defecation, greases & oils, as well as bacterial biofilms.   


What is the difference between a Bacterium and an Enzyme

An enzyme is a protein able to degrade a specific complex molecule into two smaller single molecules. It is not viable as it is unable to reproduce itself. The efficiency of an enzyme can last from 24-48 hours and can only react on one specific type of component (i.e.:  lipase ⇒ greases, protease ⇒protein, amylase ⇒ starch). In other words, the enzyme is able to degrade accumulations of organic matter into a "soup".  As for a bacterium, it can reproduce itself because it is viable.  Bacteria produce and release enzymes that degrade complex molecules into single molecules.  Then, the bacteria absorb the single molecules allowing them to grow and reproduce themselves.  By-products resulting from degraded single molecules are mainly CO2 & water. Thus, the effect of a bacterial & enzymatic product is faster and lasts longer than bacterial or enzymatic products alone. Nuvac's products consist of a combination of enzymes that degrade a specific type of organic matter (faeces, greases, oils, etc.).


What is the difference between bacteria released from humans (in the sewer system) and NUVAC's bacteria? 

Bacteria typically found in sanitary sewer systems or residential septic installations come from humans. These bacteria work and grow at an ideal temperature of 37oC. They produce and release a limited amount of some types of enzymes, and must be in optimal conditions (in the human body, requiring oxygen and high temperatures). Once in the sewer system or septic installation, the water temperature is usually around 10oC and there is almost no oxygen. Nuvac's selected bacteria are able to grow with or without oxygen, but they grow faster with oxygen. Our bacteria are also selected for their ability to produce and release a significant amount of enzymes. Furthermore, their specialized enzymatic production, such as lipases degrading greases & oils, influenced our selection.  


What benefits do we get from using your products in sewer systems? 

  • Less time & lower cost for the maintenance of the sanitary sewer system or septic tank. 
  • Higher efficiency of the wastewater treatment process.
