In this work, the investigation of the potential of acidity and basicity (pH) and amount of synthetic wastewater affecting the efficiency of the fat oil and grease adsorption and the filtration of the suspended solid was carried out using cattail flowers, sugarcane bagasse and water hyacinth as adsorbents. The synthetic wastewater used in the study was similar to community wastewater. The pH of the synthetic wastewater used in the study was adjusted to 4, 5, 6, 7, and 8. Twenty grams of adsorbent was used to adsorb oil and grease in two liters of the wastewater. The results indicated that the pH of the wastewater was 7 with the cattail flowers as an adsorbent that were suitable for adsorbing fat oil and grease. The efficiency of fat oil and grease adsorption and the percentage of removal suspended solid were 99.54 and 80.61 %, respectively. The results showed that when synthetic wastewater increased to 3, 4, 5, 6 and 7 liters, the ability of the fat oil and grease adsorption in the synthetic wastewater decreased. The cattail flowers (20 grams) could adsorb the oil and grease of 4 liters. The synthetic wastewater, the fat oil and grease remaining in the synthetic wastewater did not exceed the standard of the community effluent. In addition, the results pointed out that the filtration of the suspended solid decreased if the synthesis wastewater increased.
