Case Study
 
The Challenge:

A leading petroleum refinery was facing acute water scarcity as the local municipal bodies were unable to meet the customer’s requirement of water. Shortage of water also led to temporary closure of the refinery resulting in huge financial losses. This was the situation when the refinery was in the process of expanding its operation and thus needed to ensure self reliance for water. Also, waste water generated from the facility would have to be treated to meet stringent effluent discharge norms set by the pollution control board.
 
The Solution:
After carefully studying the effluent from the entire facility, we recommended the innovative INDION  Ultra Filtration system followed by a cost effective INDION Reverse Osmosis System operating at high recoveries.
 
 

Inlet Condition

Outlet Condition
TDS = 1860 ppm
TDS = 40 ppm

BOD = 20 ppm

BOD = BDL (below deductible limit)

COD = 250 ppm

COD – BDL (below deductible limit)

Inlet Flow = 969 GPM

Outlet Flow = 824 GPM
 
Results:
  • Assured availability of 824 GPM water  of consistent quality for process
  • Reduced requirement of fresh water resulted in a saving of US $ 2 million/year
  • Compliance with pollution control board norms.
