The WET™ system anchored by HUBER ThermWin® technology
With over 150 years of operating history and 54,000 installations around the world, HUBER Technology is a recognized leader in the wastewater industry. HUBER specializes in the production of high-quality machines, plants and stainless-steel equipment for municipal and industrial water, wastewater and sludge treatment.
The HUBER ThermWin® technology combines the proven ROTAMAT RoK4® screen that separates solids and manages sludge at the sewer level with the self-cleaning RoWin® heat exchanger that facilitates the safe and reliable transfer of thermal energy to and from wastewater. The 6mm perforated basket and auger assembly of the RoK4® ensures that only sieved brown water is pumped to the RoWin® heat exchanger. Inside this reimagined, shell-and-tube heat exchanger, an automated, internal trolley system scrapes-off any biofilm build-up on the tube bundles to ensure that the transfer of thermal energy is not impeded. Odours are contained, manual cleaning is avoided and wastewater consistency unaltered.
HUBER ThermWin® technology anchors Noventa’s WET™ systems which are configured to accommodate the unique thermal energy needs and spatial limitations of each customer. We tie directly into the customer's HVAC system and provide thermal energy that improves efficiency and system performance, saving energy costs and reducing carbon emissions.
HUBER ThermWin® technology - Energy from wastewater
Our innovative WET™ systems overcome the challenges inhibiting the decarbonization of our dense urban centers. They are primarily inconspicuous and built with little or no interference to a customer’s business activities. They typically include the following material components:
The Wetwell
A Wetwell constructed perpendicular to a sanitary or combined sewer through which wastewater is accessed. The typical Wetwell is a vertical shaft, having a diameter of ~20ft and a depth of ~ 60ft or 10ft deeper than the bottom of the sewer. A manhole at grade provides access. A pipe connected to the sewer at about “5 o’clock” allows wastewater to flow via gravity to the bottom of the Wetwell that contains the patented HUBER ROTAMAT® RoK4 pumping station which screens solids larger than 6mm. Sieved wastewater is then pumped up through the Wetwell to the HUBER RoWin® heat exchangers in the Energy Transfer Station. Any sludge that passes through the fine-screen basket of the RoK4®, is carried up through the Wetwell by a slow-moving auger to a point where spent wastewater returning from the HUBER RoWin® heat exchangers flushes the sludge back into the sewer through another pipe downstream that taps into the sewer at about 2 o’clock.
Underground Distribution Networks
An Underground Distribution Network comprised of high-density polyethylene (“HDPE”) distribution pipes that circulate the screened wastewater between the Wetwell and the HUBER RoWin® heat exchangers.
Energy Transfer Station
An Energy Transfer Station (“ETS”) that houses the patented, self-cleaning, Huber RoWin® heat exchangers and Trane heat pumps or chillers that work together to accomplish the thermal energy transfer between the wastewater and the buildings. Noventa typically constructs the ETS above grade but, these can also be designed to sit below ground.
Energy Supply Loop
An Energy Supply Loop (“ESL”) also comprised of HDPE pipes that circulates thermally modified water between the heat pumps in the ETS and the building’s HVAC system.
For every 1KW of electric energy put into a heat pump, Noventa’s WET™ system can produce over 6KW of eco-friendly energy to heat and cool buildings.
