Need information on wastewater treatment in India - Is aerobic or anaerobic treatment more popular?

Hi

I am an Indian student studying a bachelor degree in environmental studies at NHL University in the Netherlands. As part of my studies, I am doing a research about anaerobic wastewater treatment of industries like paper, food and beer in India.

I would like to get the following information

1)What is more common in India- Aerobic or Anaerobic wastewater treatment?

2)Why is that kind of wastewater treatment more popular?

3)Are Indian companies in various industries interested in anaerobic wastewater treatment?

Your knowledge and information will be very useful for my research.

Thank you so much.

Kind regards,
