Myth or Fact?


Debunking the Myth of a Wastewater Recovery Threat

With the development of any new product come those who fear potential risks. In the case of the Eco-Safe Digester, many worry about the extra burden of adding 100 gallons of liquefied nutrient-neutral grey water per day to the sewer system and the impact that this new waste disposal strategy will have on Water Resource Recovery Centers (formerly known as Wastewater Treatment Facilities). Despite these concerns, the actual implementation of the Eco-Safe Digester will not have any negative effects on these facilities nor add any extra burden to their process.

The Eco-Safe Digester does add more “waste” to the entire system; however it is in the form of a pre-filtered, pre-processed liquid effluent containing no solids – resulting in a quicker output of energy and potable water.

Once the effluent from the Eco-Safe Digester goes down the drain to the water resource recovery centers, it has to go through the same 6-step process as the rest of the wastewater.  It all begins with a preliminary step, where the water is pre-screened to remove large items – since the effluent is already void of any large items it quickly moves through this step.  The water is then transported by gravity into primary settling tanks, where some of the grit and scum is separated to form primary sludge. The water then moves on to the aeration step where the water is exposed to air by means of fine bubble diffusers, removing the dissolved gases (this is the step in which energy is removed from gases emerging from the water).  Then, the wastewater moves on to sedimentation tanks, where more of the organic portion of the sludge is removed and processed in digestion tanks. After removal, sludge solid is kept in heated tanks for 30 days resulting in the creation of fertilizer. Finally, the solid-free water is released into a ‘chlorine contact’ tank, intended to kill off the remaining bacteria. As the bacteria dies off, the chlorine is eliminated, resulting in safe, potable water. After this step, the water is then released into lakes or oceans, or is able to go back to the faucets of the public. It is this robust process that has worked for many years turning sewage waste into NEW water.

If not for the recycling actions of these water resource recovery centers, there would be excessive amounts of soiled water concentrated in towns and cities, contaminating soil and ruining ecosystems. If not for the Eco-Safe Digester, more and more food waste would continue to pile up in landfills, contributing to the release of harmful gases such as methane into the atmosphere.

Both businesses work in harmony to recycle our garbage into a reusable and useful product, protect both the environment and ensure the public’s health/safety.  Therefore, there would be no logical reason as to why technology like the Eco-Safe Digester would work to undermine the Resource Recovery Centers.
