✔️✔️what is sludge and how is it treated?
⭕️Semi-solids such as faeces that settle down during wastewater treatment are called sludge.
⭕️ sludge is removed using a scraper and then transferred to a tank where it is decomposed by anaerobic bacteria to produce biogas.
⭕️ This biogas is used as a low-cost fuel for heating, cooking, etc.
⭕️ It is also used to produce electricity.
✔️✔️what exactly happens to the sludge after the treatment is done ?
⭕️Sludge is passed through a digestion chamber where it is decomposed by anaerobic bacteria which results in liquefaction.
⭕️ After this the digested sludge is disposed by drying and then landfilling.
