The aeration waterjets are devices used for oxygenation and mixing of wastewater in biological treatment processes, as well as in the biological reconstruction processes of all types of water where aeration of the medium is required. By creating a strong stream of a mixture of liquids and air bubbles, the power jets create particularly favorable conditions for oxygen transfer and prevent sedimentation.
S1 spotlights can be divided into three versions:

  1. S1 – straight for tanks below 4.5m depth
  2. S1P – straight with raised discharge pipe for tanks from 4.2-5.5m
  3. S1S – slanting for tanks 5.5-7-5m deep
