Diammonium Phosphate (DAP)

Value Proposition

Provides a dual-nutrient boost that stabilizes microbial activity. Its high solubility ensures immediate availability for bacteria, preventing “sludge bulking” and ensuring a healthy, settling biomass.

Applications

• Commercial

  • Maintenance of decentralized sewage systems

Technical Specifications

• Ammoniacal Nitrogen: Min. 18%

• phosphate: Min. 18%

Process Description

DAP is typically dissolved in a dosing tank and fed into the biological stage. The phosphorus acts as an energy carrier (ATP) for the microbes, while the nitrogen supports growth.
