I actually work in steem power plant too, well its just making so much polution, such as fly ash, waste water and waste material. It doesn't mean that we dont do treatment, we do !! But the thing is, the amount of polution is just increasing along with operation time, in the end the desain of the plant or waste water plan or dust collector plant don't really mean anything, its just the marketing value that really matters in bussines now days, they don't care about the enviroment, just provit.
i really hope that what you post that can make some bussines man out there or soon tobe bussiness man realise and care about enviroment. Over all good post my friend
