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 mostly within the Coca-Cola standards. The trials were conducted at Dasna for reduction of WUR which was above 2 for the month of February. It was observed that it is the behavioural change which plays a major role here as most of the facilities present could substantially bring down WUR from crossing 2.Most of the plants maintain a WUR less than 2.Wastewater parameter studies on Dasna showed that DO in aeration tanks are low and needs to have a diffused aeration system as proposed in its ETP upgrade plans.
The study on Sewage treatment plant is only groundwork data collection and further capacity evaluation against the design has to be carried. Also, the data collection has been made on sludge handling and cost for all the plants. Efficient handling and standard practises can be devised and a standard can be derived for plants.
