An effluent before it is to be discharged has to be treated to kill its hazardous effects. If an effluent is acideic , than it has to be neutralized using some base like hydroxides to make it neutral and if its too basic then Sulphuric acid is added to make it neutral. ALso floculants and co-agulants are also used to remove the impurities and solid wastes present in the liquid.After that many pH test,conductivity tests and its concentration is examined before it is discharged. All this is carried out in ETP plant.

What safety precautions should be taken before cleaning a heat exchanger?
Prior to cleaning a heat exchanger, one should be sure to use hand, body, and eye protection. One should not conduct acid and bleach flushing simultaneously, as this produces a noxious gas which can be lethal if inhaled for an extended period of time.
What precaution should be taken carrying experiment using pH meter?
wash the pH probe with distilled water and then dry it clean with tissue paper before and after testing the pH.
What is the recommended iron content in the refinery water?
The recommended iron content in refinery water typically should be below 0.1 mg/L to prevent corrosion and fouling in refinery processes. However, this limit can vary based on specific refinery operations and local environmental regulations. Maintaining low iron levels is crucial for ensuring the efficiency and longevity of equipment and for meeting discharge quality standards. Regular monitoring and treatment may be necessary to achieve these levels.
