PTG’s systems provide significant cost savings and performance advantages for municipal wastewater treatment facilities of all sizes from as low as 0.1 MGD to over 150 MGD.

The Problem:
Wastewater treatment facilities are faced with the storage and usage of toxic chlorine, expensive UV lights, high electricity costs and the probability of releasing untreated water into streams, rivers and oceans.

  • Massive cost savings from reduced electricity and chemical costs
  • No chlorine or chlorinated by-products (no toxic chemicals)
  • No UV (no costly electricity usage)
  • Renewable generation of electricity
  • Use biogas, natural gas or available biomass
