"Tosho DAP" serves as a nutrient for activated sludge microorganisms to maintain ideal metabolic functions. Specifically, it consists of nitrogen [N] and phosphorus [P], which are essential for the cell nucleus and enzymes that are the foundation of microbial life. The standard product of "Tosho DAP" is sold in the appropriate nutrient balance for sludge treatment at a ratio of "BOD (Biochemical Oxygen Demand): N: P = 100: 5: 1," but nitrogen [N] and phosphorus [P] can be adjusted to the necessary ratios based on the analysis results of the raw water (wastewater). [Benefits] ■ No need for dissolution equipment ■ Streamlining of processes ■ Simple management in handling ■ Suitable for balancing nutrient sources *For more details, please download the PDF or feel free to contact us.
