Abstract: Water is extensively used in most process industries for a wide range of applications. The stringent environmental regulations are applicable to these water-intensive industries today and are thereby forcing these industries to adopt more efficient and advanced treatment facilities. This study was carried out to analyse the wastewater characteristics of the effluent treatment plant of a beverage industry and thereby explore the opportunities for improvement in terms of compliance, capacity and or capability. The parameters of prime importance in wastewater characteristics like BOD, COD are within the Coca-Cola standards. The trials were conducted at Goblej plant for segregation of high TDS streams and the possibility of treating it with Rainmaker was explored. The utilities wastewater which has a high TDS could be segregated along with the high TDS streams of Dealkalizer regeneration.
Streams from the utilities like boiler blowdown and cooling tower blowdown contributing 5500 and 10,500 mg/L can be segregated and sent to Rainmaker. The quantities of both would increase approximately 100m3 of wastewater per day to the Rainmaker which is currently handling 500m3 of wastewater. The design capacity of Rainmaker being 720m3, it should be all right to handle this utilities wastewater. The other streams with lesser than 2000mg/L TDS streams should not be a concern to the ETP.
The regeneration trials were observed to be carried out in a haphazard manner and following a standard procedure could save a lot of water for the manufacturing plants. The operators are to be trained extensively and monitored closely for this. This study also shed some light on the extent of compliance on the consent conditions mentioned in the PCB consent maintained at the plant level. A more comprehensive file shall be maintained which would support the compliance with evidence adding credibility to this file.
