Evaluation and improvement of the WWTP performance of an agricultural cooperative by adsorption on inert biomaterial: case of orthophosphate, nitrate and sulfate ions

Abstract The study is carried out at the wastewater treatment plant (WWTP) of an agricultural cooperative that operates according to activated sludge process. Dairy industry enlisted as one top-most industries in food industry. a big issue dairy releases high amount chemical oxygen demand, inorganic and organic particles, biological nutrients. But, these processes partly degrade containing fats nutrients wastewater. aim this was evaluate purification performance qualitative analysis decanted raw (DRWW) purified (PWW) shows concentration orthophosphate, nitrate sulfate ions slightly higher. Such contaminated water if not handled appropriately, it pollutes bodies largely affects our ecosystem biodiversity. Hence, proposal improve WWTP performances by using adsorption process onto dried Carpobrotus edulis inert biomaterial. This recognized best techniques, more works are oriented towards search for new materials, cheaper having good adsorbent potential. opens path use natural abundant local material remove C. particles shred. surface micromorphology biomaterial investigated scanning electron microscope; while element composition analyzed energy dispersive X-ray infrared spectroscopies. found results DRWW about 57% orthophosphates, 67% sulfates 73% nitrates ions. For PWW, percentage removal be 62%, 84% respectively. These indicate plant, environmentally friendly could recommended mineral pollutants. In conclusion, can integrated into after identifying optimal hydraulic loads, associated sizes, shapes continuous operations.
