To concentrate effluent generally evaporation technic is used. During evaporation plant operation, due to inorganic & organic contents in effluent, fouling occurs on surface of tubes after some duration. This reduces the capacity of plant & need to be cleaned by Cleaning In Place (CIP). If we find the suitable Non-fouling metallic surfaces / coatings for tubes, we can reduce the CIP chemical & water consumption & down time of cleaning. This can give benefit for plant operation and water saving.
During various unit operations vapors are getting generated for separation of water, which are then condensed. While handling the effluents, process mixtures, the volatile acids are coming out along with vapors and then in condensate, which is generally colorless. For recycle & reuse of this separated water, we have to treat this to remove volatile acids (main component Acetic Acid). If we innovate / develop techno-economic solution for removal of such volatile acids, lot of water will be reused
In nature we can see lot of Biomass & which can be used for various applications. But for processing this biomass for particular use, we need to do size reduction. At present there is equipment available which can do this, but the power consumption for unit operation is very high. This increases the operating cost of that plant. If we can design / develop size reduction equipment with low power consumption, then it will benefit all biomass based industries.
