Energy recovery scheme for a water distribution network.

Energy recovery scheme for a water distribution network.

Energy recovery scheme for a water distribution network.

(OP)
Hello All,

 My name is oscar and I am designing an energy recovery scheme for a water distribution network. The scheme involves clean water transfer from treatment works by gravity to a reservior .There is an existing pressure reducing valve at the inlet into the reservior and discharge is not at atmospheric pressure.
Head duration Curve(HDC)
27%----84m
63%----52m
10%--- 0m


flow duration curve(FDC)

95%----0.12m3/s

I have attached the HDC,Flow duration Curve and other curves.

My questions are:

---what type of turbine might be suited for this scheme?
---is it going to be variable speed turbine or constant speed?
---- What design head might be suitable for such a scheme
Thanks


 

RE: Energy recovery scheme for a water distribution network.


The Zeropex company is already commercializing (Norway, UK and US)a patented combined product of the type you are looking for: reduction unit, el. generator and patented control for el. output.

Altough there is limitations to the use and a very sketchy reference to the real technical side of the unit, a contact might help you.
