SYNOPSIS
SCALEBAN PROJECT AT 80 KLD GRAIN BASED DISTILLERY PLANT OFGULSHAN POLYOLS FOR OPTIMIZING WATER CONSERVATION & ZLDOBJECTIVES ON A SUSTAINABLE BASIS.
Gulshan Polyols have implemented “SCALEBAN” technology at ethanol distillery division, Chhindwara, MP for their 80 KLD grain based distillery plant to utilize their wastewater directly at distillation & evaporation plant cooling towers to stop operation of wastewater RO and Multi Effect Evaporator.
Background of “SCALEBAN” Project
Gulshan Polyols Ltd is India’s leading manufacturer of ethanol/bio-fuel, grain and mineral based specialty products. At their distillery plant at Chhindwara350-400 m3/day wastewater is generated which is presently being treated through available conventional technologies like wastewater RO and Evaporator (MEE) for achieving ZLD
Challenges for Gulshan:
Due to high operating cost of wastewater RO and Evaporator (MEE) to treat RO reject besides their operational difficulties, Gulshan management was searching for a sustainable solution to stop operation of these conventional technologies.
Gulshan Approach:
While searching right solution for their problem, Gulshan management came across “SCALEBAN” technology and after verifying the performance with our existing clients in India.
In the first phase, Gulshan management awarded contract to “Scaleban” to implement “SCALEBAN” technology at their distillation and evaporation plant cooling towers to utilize 200m3/day treated wastewater (wastewater RO Feed)in place of fresh water to reduce load on wastewater RO and Evaporator (MEE)to treat RO reject. This project was implemented in the month of August 2022and till date we are successfully using their wastewater in cooling towers at high COC and achieved zero scale, corrosion and bio-fouling free operation of the entire cooling tower circuit and stopped operation of wastewater RO &MEE. We implemented “SCALEBAN” equipment at the inlet of all the condensers/coolers of Distillation plant including at the inlet of surface condenser of Evaporation plant.
