There is hardly any difference in the design or the cost. We provide a single system where MAST technology uses a combination of microbes and algae to treat the wastewater. While the selection of the microbes and algal species will differ for either of the applications, the other difference could be the HRT (Hydraulic Retention Time). While India has a tighter requirement in municipal sewage for BOD5 which calls for an additional treatment using Multistage Fixed Film System to treat the sewage. So the CAPEX and OPEX will go up. 

I cannot give a comparison in terms of cost for Pakistan as I am not aware of the discharge guidelines adopted by the Pakistani Government. 

Our MAST technology is a self sustaining system that generates profits and revenue for the customer and therefore while there would be an initial capital investment this can be recovered in 5-8 years time. The operating expenses are recovered from the revenue generated by products produced by the MAST technology wastewater system.

In case of pharmaceutical effluent it is important to treat the endocrinal disruptors and the process of treatment will require more detailed study.
