Effect of wastewater depth to the performance of short

Nov 01, 2020 · The parameter of pH was not significantly affected by the changing in wastewater depth and the utilization of plants. DO measurements showed that 35 cm wastewater depth gave a better aerobic condition (up to 6.97 ± 0.35 mg/L) as compared to the 45 cm (maximum only 5.64 ± 0.28 mg/L), resulting in higher removal of BOD 5 and COD.

As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.

In primary treatment, what are the pH process controls for

The starting and ending pH values in large part determine the treatment procedure. The pH adjustment requires residence or contact time during the wastewater treatment for the pH to change as needed. Traversing a very narrow pH range (i.e., 7.0 to 8.0) requires less contact or residence time compared to a wider pH range (i.e., 7.0 to 10.0).
