Which type of waste is commonly managed in water treatment plants?

• A. Solid waste from food processing
• B. Chemical waste from labs
• C. Sludge and other by-products of water treatment
• D. Household trash

Answer: (C)

The management of sludge and other by-products of water treatment in water treatment plants is essential for ensuring environmental compliance and operational efficiency. During the treatment process, various materials are removed from the water, including sediments, organic matter, and microorganisms. This material, collectively referred to as sludge, must be processed or disposed of properly to avoid pollution and public health issues. In many water treatment facilities, sludge undergoes further treatment steps such as thickening, digestion, and dewatering, which can reduce its volume and prepare it for safe disposal or beneficial reuse, such as in agriculture. The handling of sludge is an integral part of the wastewater management cycle, making it a primary focus for water treatment operators. Other options listed involve waste types that are typically not managed directly by water treatment plants. Solid waste from food processing, for example, is generally handled by solid waste management facilities. Chemical waste from labs may require special hazardous waste management procedures outside the scope of standard water treatment practices. Similarly, household trash falls under municipal waste management services and is not part of the water treatment process.
