Dear Ahmad Abo Omar,
Wastewater aeration is the process of adding air into wastewater to allow aerobic bio-degradation of the pollutant components. It is an integral part of most biological wastewater treatment systems. Unlike chemical treatment which uses chemicals to react and stabilise contaminants in the wastewater stream, biological treatment uses microorganisms that occur naturally in wastewater to degrade wastewater contaminants.
Probably a pre- aeration treatment chemical like H2O2 or other oxidants like, ozone, c hlorine dioxide injected at headworks, equalization tank, to Then you will have to look at cost effectiveness.
Best way try adding Algal or Spirulina cultures instead of chemicals
