What are the effects of hydraulic jump?

The use of hydraulic jump in hydraulic engineering is not uncommon and the creation of such jumps has several purposes:

(i) Its main aim is to perform as an energy-dissipating device to reduce the excess energy of water flows.

(ii) The jump generates significant disturbances in the form of eddies and reverse flow rollers to facilitate mixing of chemicals.

(iii) During the jump formation, considerable amount of air is entrained so that it helps in the aeration of streams which is polluted by bio-degradable wastes.

(iv) It enables efficient operation of flow measuring device like flumes.

Do we use this phenomenon to mix chemicals???
or some other machines are there?
