1. Single pit technology:
Advantages: Simple technology, low (but variable) capital cost
Disadvantages: Flies and odors are normally noticeable, low reduction of pathogens with possible contamination of groundwater, costs to empty may be significant compared to capital cost, and sludge requires secondary treatment and/or appropriate discharge
2. Double pit technology:
Advantages: longer life than the single pit, easier emptying, significant reduction in pathogens, flies and odors significantly reduced, and product can be used as soil conditioner
Disadvantages: Manual removal of humans is required, possible contamination of groundwater, higher capital costs than single pit but reduced operation costs if self-emptied.
3.Anaerobic technologies:
3.1 Septic Tank
3.2 Anaerobic Baffled reactor (ABR)
3.3 Biogas reactor
4. Aerobic technologies:
4.1 Free-water Surface Constructed Wetland
4.2 Horizontal Subsurface Flow Constructed Wetland
4.3 Vertical Flow constructed Wetland
Dear E T.
Pl take time and study in detail the details given in my research developmnt paper on DEWATS..
This describes all the devices given by you, starting with Anaerobic process till Constructed Wetland using plants.
Here you may introduce Algae as media for process and take up Algae and effluent for re use to get maximum potential of the wwt plant in use.
The research paper is attached here.
Well wishes
Dear Prof. Ajit Seshadri
Thank you so much.
It sounds really interesting and I can find my answer here.
1. Distribution of sample site should be equally distributed.
2. sample from different industrial units.
3. sample from well, tube well, river, and lake

In large rural properties that breed animals in confinement in Brazil, there is currently a strong trend towards the integration of biodigesters into wastewater treatment systems. In addition to numerous environmental advantages, there are economic and social and relevant benefits. I think the system is here to stay.
Dear Prof. Viníciu Fagundes Bárbara
Thanks for your response, and it is good to hear that.
Carbon filtering removes remaining contaminants and impurities by chemical absorption onto activated carbon. Filtration through sand (calcium carbonate) or fabric filters is the most common method used in municipal wastewater treatment.
