Can pumps be used other than bladder pumps and do submersible centrifugal pumps affect DO?
Can pumps other than bladder pumps be used and do submersible centrifugal pumps affect DO?
Other pumps can be used. The best way to answer the question is that any pump that has a flow rate that can be controlled so that you can maintain a specific drawdown level in the well will work effectively. That could be a peristaltic pump, it could be an electric submersible centrifugal pump, it could be a bladder pump, it could be a piston pump. There are many different types of pumps that would work as long as you can adjust the flow rate to the appropriate flow rate desired for that well. That being said, the second half of your question, do electrical submersible pumps affect DO concentration, yes, they can. It depends on what's going on, you have one or two things that can happen. You can either lose dissolved oxygen due to agitation. Or more commonly, you can gain DO using an electrical submersible pump, especially when it’s open-faced type impeller pump. In the case of those pumps, in a gas charge system, we get cavitation. We can see a significant increase in DO in samples. So the answer of the question is depending on your groundwater chemistry, there are variety of different pumps that can be used as long as the flow rate can be adjusted. But electrical submersible pump in some situations can change the DO value.
