Oils and fats should not be released in the drain to prevent clogs and water pollution. The steps to clarify water from wastewater involve several treatment stages. Sludge is the solid material in wastewater that undergoes treatment processes for disposal or reuse.
Oils and fats should not be released in the drain because they can cause clogs in pipes and contribute to water pollution. When oils and fats solidify in pipes, they can trap other debris, leading to blockages and potential sewer backups.
The steps involved in getting clarified water from wastewater include pretreatment (screening and removal of sand and gravel), primary treatment (settling or floatation to remove organic solids, fat, and grease), secondary treatment (aerobic bacterial decomposition of organic solids), tertiary treatment (bacterial decomposition of nutrients and filtration), and disinfection.
Sludge is the solid material that settles out in wastewater treatment. It is treated through processes like digestion to break down organic matter, dewatering to reduce its volume, and sometimes incineration or landfill disposal for ultimate treatment.
