What are the advantages of WWTP in Sugar manufacturing units?
One of the most widely utilized essentials in practically every household today is sugar. Due to its taste-improving properties, it is used to brew tea, coffee, and other delicacies. Along with other foods and beverages, sugar is utilized in soft drinks, ice cream, candy, and pastries. The majority of sugar mills in India are found in rural areas, and run for four to eight months right after the sugarcane harvest.
Producing so much sugar leads to wastewater generation! Isn’t it? So, do you want to discover the advantages of wastewater treatment in the industries that process sugar?
Categories of sugar manufacture
These are the several categories for sugar manufacturing:
1: Manufacturing of gud and raw sugar.
2: Khandsari produces unrefined, inferior sugar.
3: Process of double carbonation and double sulphitation.
Description of the Sugar Industry's Processes:
The following are the various steps involved in the manufacturing of sugar:
1. Purchasing sugarcane.
2. Sugarcane milling.
3. Making of juice.
4. Juice Focus.
5. Crystallization and Syrup Processing.
6. Molasses handling, drying, packaging, and sugar crystal separation.
7. Making use of bagasse.
How is sugar produced?
The sugarcanes are broken into pieces and crushed in a succession of rollers, in the "mill house" to extract the juice. After all the colloidal and suspended contaminants have coagulated, the milk of lime is added to the juice and cooked. Much of the colour is also gone during this process.
The sludge is subsequently removed from the coagulated juice by clarification. The clarifier sludge undergoes additional filtering in filter presses, before being disposed away as solid waste. Sulphur dioxide gas is used to treat the entire batch of clarified juice, after the filtrate is recycled back into the process, by Sulphitation. It entirely bleaches out the juice's colour.
Wastewater produced from sugar manufacturing
Sugar is produced from sugarcane, which contains a lot of water. A lot of effluent is created throughout the production. This is not the end of the procedure, though! For carrying out further processes, more water is needed. As a result, wastewater discharge harms the environment. Additionally, it makes people more dependent on other clean water sources.
Therefore, in such a case, wastewater recycling treatment proves to be of great benefit. Do you know why local sugar producers are developing wastewater treatment facilities? It is happening in order to produce freshwater for later use.
Other advantages of Wastewater Treatment in the Sugar Industry
1: Firstly, the water generated can be used to wash raw sugar of its colour, using wastewater treatment. The treatment involves the Reverse osmosis or ultrafiltration procedure, and the clean water that is created may aid in the crystallization of purified juice.
2: Secondly, combining the nitrification and de-nitrification processes during wastewater treatment, aids in eliminating nitrogen molecules from the water. Finally, the produced product might be applied to additional sugar production operations.
3: Lastly, membrane solution generated by wastewater treatment in the sugar industry is useful for extra tasks, like clarifying and adjusting juice concentration. Reverse osmosis and ultrafiltration are two processes the wastewater goes through, before being transformed into pure water that can be used further.
