Liquid Waste Management includes the creation, collection and disposal of non-hazardous liquid waste like storm water to prevent the discharge of pollutants into the drainage system or water bodies. It follows following steps:
- Primary treatment
- Secondary treatment
- Tertiary treatment
Liquid Waste Management
As the name suggests, Liquid Waste Management includes the creation, collection and disposal of non-hazardous liquid waste like storm water to prevent the discharge of pollutants into the drainage system or water bodies.
- Sewage Treatment Plants (STP) – STP treats the incoming sewage water and converts it into reusable and treated water which is ready for disposal.
- Fecal Sludge Management (FMS) – Human feces are collected in septic tanks and other onsite sanitation systems. This waste is then collected, transported and treated in an FMS.
- Effluent Treatment Plants (ETP) - The principle of operation of ETP is Physico-Chemical treatment followed by Polishing Treatments like –Sand Filtration, Activated Charcoal treatment (Adsorption), Ozonisation (Chemical Oxidation), Ultra Filtration (UF), Reverse Osmosis (RO) and evaporation (If required).
- Physical Treatment, Chemical Treatment and Biological Treatment are the three steps followed in liquid waste management. Machineries required in physical treatment are Screen, Grit Chambers, Clarifiers, Chemical Reactors, Trickling filters, Activating Sludge plant, Rotating Biological Contactors, Digestors
