Liquid waste refers to any unwanted or discarded liquid material that is produced by households, industries, or agricultural activities. This type of waste can include sewage, wastewater from factories, and runoff from farms. Proper management of liquid waste is essential to prevent pollution and protect public health. Liquid waste can contain harmful substances, such as chemicals, pathogens, and nutrients that can contaminate water sources. Treatment processes, such as those used in wastewater treatment plants, help to remove these harmful components before the water is released back into the environment or reused.
