هزینه احداث واحد خنثی سازی فاضلاب صنعتی چقدره؟؟؟
درضمن اگر فاضلاب داری غلظت 1 مولار سدیم هیدروکسید باشه بهترین روش خنثی سازی چیست؟؟؟ و هزینه روزانه چقدر خواهد شد؟؟؟؟
Excuse me for expressing that, but this is a very very general question and does n`t look like to be an acceptable way of searching for a graduate student to look for the answers of these types of question in a general forum like this, instead of searching through papers and google scholars etc
However as you requested I am going to give you a few guidelines for that. Coming back to your question regarding the cost, it is highly dependent to the capacity of treatment plant and deficit to normal level(pH adjustment level) as well as the type of system which is used and safety factors
Usually its a kind of building and tanks and dosing pumps for chemical injection and that's all, very simple so, having calculated the chemicals required, you will come up with the idea of total number and power of pumps for injection and civil works which would be the easier parts would also be added to the marginal costs, then you have to add operational costs including maintenance and PM(if any) and electricity and chemical usage in life period to have the total cost using one of economical estimation tools such as current value method
For the second part of your question please note that
Sodium Hydroxide (NaOH)Also known simply as caustic, is the most widely used alkaline neutralizing chemical in use in industry today. So its kind of chemicals used for neutralization itself and in case you overdose that or simply have a basic sewage, you might add some kind of acetic agents for neutralization depending on molarity of the acid and neutralization equilibrium that you will find many available commercial agents to deal with.for instance sulphoric or hydrochloric acid might be used.
There are many available sources through the internet and I wonder how you were unable to find them, however just as an example, take a look at this site for further review:
