Incorrect Operation and Improper Maintenance

Sudden generation of effluents shock loads on the ETP) during mechanical trials of equipment and machinery by not following careful methods for the trials. 

Frequently stopping and restarting the plant during commissioning stage itself leading to generation of off-spec products or process waste  

Frequent product change over due to pressure from marketing department— requires frequent washing of process reactors and this can generate effluent streams  

Plant overloading beyond rated capacity—can result in escape of unreacted inputs, acid mist, unabsorbed gases, etc.  

Choked spray nozzles in scmbbers—these cannot deliver sufficient scrubbing liquor or can spray only on one side and cause channelling
