Piggery wastewater refers to the liquid waste generated from pig farming operations. It comprises various components, including dung and urine from the pigs, as well as water used for cleaning the hog housing facilities. This wastewater is characterized by its high concentration of ammonia, which is a byproduct of the breakdown of nitrogenous compounds in pig waste. Piggery wastewater poses environmental challenges due to its potential for groundwater contamination and the release of odorous gases. Effective management and treatment of piggery wastewater are essential to minimize its impact on surrounding ecosystems and maintain a sustainable and hygienic pig farming environment.
