River Clean-Up / Hydro Power

Goodwin submersible slurry pumps can often provide the perfect solution to assist with silt removal at River Water Intakes / Hydro Power generation plants.

 

Due to their nature rivers have variable flows depending on the amount rainfall in their catchment area. After a heavy rainfall the river flow will increase and it will hold a lot more sediment, after its peak flow following a rainfall the flow will decrease, the water velocity will be lowered and the suspended sediment settles out.

 

At Hydro Power stations and River Water Intakes the effect of sediment deposition is amplified as normally a river will be dammed to create the head of water required to generate the power / have a supply of water. As the river water enters the reservoir behind the dam its velocity decreases and the sediment it is holding is deposited.

 

Normally the silt removal process is very timely and expensive – and may involve dredging. When dredging is performed, all activity near the place of sediment removal is stopped – which maybe a Hydro Turbine or a Water Intake station.

 

 

By using a Goodwin submersible slurry pump in most instances it is not necessary to stop the process of generating power or taking water from the river, because all the sediment (that is turned into a slurry by the hydraulic shock-wave of the pumps agitator) is pumped away (normally to just downstream of the reservoir).

 

By doing this our customers have prolonged the life of their turbines, as by keeping lower levels of sediment, less enters the turbine wearing it away. In addition to this it allows them to keep the turbine on-line generating power when previously they would have to shut it down when the sediment is cleared.

 

Goodwin submersible slurry pumps can pump up to 800m3/hr, up to 65% solids by weight, up to 60m head and up to 1000m in distance.

 

With all of the applications that are described, the reason this is such a successful pump is because it will improve your plant running time, reducing your maintenance costs and making you more money.

 

There are a host of additional features that contribute to the reliability of this Submersible Slurry Pump in the most demanding environments, some of which are shown on other application examples, to see all of them please contact us so that we can send a full brochure and arrange to come and visit you.
