After -1 -1 -1 optimizing, 2 g L moringa SP, 40 mL L SAE and 20 mg L of alum alone or in combination were evaluated.
Moringa SP was more effective than SAE and its combination to decrease EC and maintenance of pH of treated or untreated sewage water.
Moringa SAE was more effective than SP or their combination...
