Great question! Thank you for asking the question! The basic principles of sludge drying beds ( SDB) involve dewatering sludge through a combination of drainage and evaporation. Typically, a drying bed consists of several layers: Drying is facilitated by percolation/draining through the layers of sand and gravel and evaporation due to sun and wind from top sludge layer ( Generally not more than 20 cm ). At the bottom it consist of sand and gravel to facilitate the percolation of water. The drying process for the lower sludge layer is dependent on many factors including the type of sludge, weather conditions, and bed design. Drying the remaining wet portion of the sludge cake often involves a combination of techniques like additional air circulation, extending the drying period, or using mechanical dewatering methods. To address the challenge of frequent rain in Eastern India, covered drying beds , adjusting the drying time or using alternative dewatering technologies can help overcome them. I hope you got your answer. Keep watching and learning. Pls share the channel link with other students also. Thanks. Best wishes.

@061_HemanginiGoyal Thank you so much mam😊

The incineration process generally takes 1-2 hours, depending on several factors such as Type and quantity of waste: Dry, combustible waste (e.g., paper, wood) burns faster. Wet or high-moisture waste takes longer. Incinerator design and efficiency: Modern incinerators are more efficient and reduce burn time. Temperature (850°C or higher): High temperatures ensure complete combustion and reduce harmful emissions. Air supply (oxygen): Proper oxygen levels speed up the process. Combustion time: 30-90 minutes. Cooling and ash removal: 30-60 minutes. The total cycle time is approximately 1.5-2 hours, including preparation and post-combustion steps.

As per Notification for the post of executive engg and deputy executive engg only final year students are eligible for prelim exam and has to compulsory produce B.E. Degree certificate before appearing in Main exam. In other 3 post clearly mentioned B.E. Degree. Still you visit website and thoroughly read all educational qualification. Best wishes

It is already there in play list of env engg. Refer the following playlist ua-cam.com/play/PLSypi7-ZWdxb4mJ5jNpEaoj3nmO9alDEe.html&si=1Tp4TJyP542D0iCw

No I am not doing any coaching for any subjects . As a teacher, I would like to share my knowledge with all the students on UA-cam for free. With that motive only I have created this UA-cam channel & hope to reach maximum students. If any specific topic you want to learn and if its possible for me to make video I would definitely like to share it with all . Thanks for watching & commenting . Do share the link of my channel with other students too.

Thanks

Thank you so much. Keep learning and motivating me.

Happy new year!!
