Energy Recovery Solution from the Wasted Grey Water - Case Study
Energy Recovery Solution from GREY Wasted Water in Large Condos or Hotels, or in WTP or from City Sewage pipes flowing under the street.
The Energy Recover Solutions are Patented Technology with Major Benefits in different markets
A practical solution to save Wasted energy. Return On Investment possible within 1 year.
INNOVATIVE APPROACH IN HEAT RECOVERY
USING DDI Patented “Rectangular, Square, Cube” R, Very LARGE GAPS
METHODOLOGY
Failed attempts to modify existing Spiral, and Shell and Tube Heat Exchangers for Heat Recovery application due to PLUGGING or BAKING, led to the development of new breed of DDI “Rectangular, Square, Cube” R Large Gap Heat Exchangers that provide worry free, NON PLUG operation, despite presence of stringy and sticky materials in municipal sludge or Grey Water flow.
The Energy Recover Solutions are Patented Technology with Major Benefits in different markets:
1- In Waste Water Treatment Plants,
ROI is less than 1 year.
Due to DDI’s DIRECT-Sludge-to-Sludge Heat Recovery from the Hot Wasted Digested Sludge, to the Cold Raw Sludge. Low risk of plugging due to the very large gaps, and low risk of baking to the surface due to the controlled fast flow of the sludge.
2- In Wasted GREY / BLACK Water,
ROI is 1-3 years depends on buildings size.
Save 10-30% on building’s or Hotel’s heating costs.
DUE to DDI’s Rectangular channels which allow complying with the law requirement of DOUBLE Walls efficiently.
3- In Recovering Energy DIRECTLY from the CITY SEWAGE which flows below the building,
ROI is 1-2 years depends on buildings size.
Save 20-30% on building’s heating and cooling costs.
DUE to DDI’s Rectangular channels which allows for Direct flow of the City Sewage to the DDI Heat exchanger.
Without holding tanks or screens or macerators costs.
4- In “Yes Pasteurization” tm
ROI is about 1 year, depends on the WWTP size.
Due to DDI’s DIRECT-Sludge-to-Sludge Heat Recovery from the Hot Wasted Digested Sludge, to the Cold Raw Sludge. Low risk of plugging due to the large gaps, and low risk of baking to the surface due to the controlled fast flow of the sludge.
All systems are:
- Easy to install.
- Nearly maintenance free.
- Virtually clog free, no more down time from clogging.
- Savings on your energy cost
- Green promotion with new technology utilization.
