NitROE - Model WWTS -Waste-Water Treatment System

Unlike a conventional septic system, a NitROE^® WWTS significantly reduces nitrogen compounds (and phosphorus, if required). A primary application for nitrogen removal is in locations where total nitrogen compounds in septic tank discharges are excessive, causing negative environmental impacts. Based on the currently active installations, NitROE^® WWTS have been shown to consistently achieve average nitrogen levels below 10 mg/L, after the initial startup period. In addition to being discharged into a leach field or pit, the discharge from the NitROE^® WWTS with disinfection may also be discharged to a surface water body, depending on the particular state regulations, or it can be beneficially reused for non-potable purposes, such as non-food crop [or lawn] irrigation.

The KleanTu NitROE^® WWTS consists of a conventional septic tank (may be existing septic) and one or more NitROE^® treatment tanks based on the daily volume of wastewater being treated. The NitROE^® tank (or multiple tanks) is the same size and construction as a conventional septic tank, but it contains the treatment components to remove organic matter and nitrogen. The WWTS can be designed for single-family up to multiple unit residential or commercial properties with design flows of 200 to 2,000,000 gallons per day (GPD).

Gravity moves wastewater through the tanks so that the only piece of mechanical equipment is an air pump, which quietly operates from beneath a faux rock. The KleanTu^® NitROE^® upgrades conventional septic systems so that there is always a minimum of septic system treatment even in a power outage.

Installation for smaller units can be done within days, with little disruption to the homeowner, and the final area can be landscaped with no obtrusive parts, no odor and minimal noise. For new construction, KleanTu^® can work with your contractors to perform the installation according to the project schedule.

KleanTu has been operating NitROE^® systems in Massachusetts since early 2017. These systems have consistently shown 90% reduction or greater in total nitrogen after the initial startup period. The graph below illustrates the total average nitrogen in and out of each of the active NitROE^® installations in December 2020. KleanTu^® continues to optimize treatment to obtain even lower nitrogen concentrations, taking into consideration variations in nitrogen influent concentrations, cold weather/water temperature and seasonal use that may affect the efficiency of removal. The system can also include treatment of phosphorus or disinfecting, if needed.
