Water and wastewater solutions for distillery & Sugar industry - Manufacturing, Other
Internationally, Ceramic membrane filters have been used for many years in beverage filtering applications including beer. In recent years the wine industry has widely adopted cross-flow filters with ceramic membrane with the membrane life being over 10 years. Across the wine and cider industries cross-flow filters are an accepted process. In Indian Distillery industries, the wastewater from distillery column called spent wash liquor. Spent liquor contains lot of suspended and dissolved impurities mainly organic, color, TDS, oil. Due to presence of high amount of impurities it is very difficult to control parameters as per pollution board limit by conventional wastewater treatment plant. Here Ceramic membrane technology has answer.
This spent wash liquor can pass through Digester to convert organic load in to Biogas which is used as a fuel of Stream and Power generation and then passed through membrane system to produce pure water or to be pass through per filtration followed by Membrane system without using primary and/or secondary conventional wastewater treatment. Membrane system will separate pure water which will be recycled in process and reject of membrane system can be further concentrated by thermal energy and directly used as a bio fuel. After preparing beer solution in fermentation process prior to distillation it should be passed through membrane system. This membrane system will remove all kind of suspended solids and high molecular weight dissolved impurities. This will help to improve the efficiency of distillery column in terms of heat transfer and maintenance as well as treatment cost of effluent treatment plant will drastically reduce. Due to saving in energy consumption in Distillery Industries by using Membrane system prior to distillation, it is crystal clear that CO2 emission also reduced substantially. This will help to reduce ozone layer depletion resulting improvement in environment.
