Dynamita DYNAMIZU v26.0: Professional Wastewater Treatment Plant Simulator (ASM)

Dynamita DYNAMIZU is the world’s most advanced wastewater treatment plant simulator, implementing all major Activated Sludge Models (ASM1, ASM2d, ASM3, ASM2d + BioP, ASM2d + Anammox, ASM3 + BioP) plus secondary settling tank models (Takács, 1D), biological nutrient removal (BNR), and industrial pre-treatment. Version v26.0 continues Dynamita’s mission of delivering rigorous, mass-balance-based process simulation for engineers, researchers, and operators. Unlike simpler empirical models, DYNAMIZU uses fundamental biokinetics (Monod expressions) and physical transport to predict effluent quality (COD, N, P, SS), oxygen uptake rate (OUR), sludge production, and greenhouse gas emissions (N₂O). Whether designing a new membrane bioreactor, optimizing an existing nutrient removal plant, or researching Anammox for sidestream treatment, DYNAMIZU delivers the accuracy and flexibility that modern water quality engineering demands.

⚡ Key Features & Capabilities

???? Activated Sludge Models (ASM)

Processes:

• Hydrolysis, growth, decay, storage, fermentation

• Aerobic, anoxic, anaerobic zones

• pH and alkalinity limitation

• Temperature correction (Arrhenius, default θ)

???? Secondary Settling & Clarifier Models

Clarifier Models:

• Takács (1D) – 10 layers, hindered/compression settling

• Otterpohl & Freund, less common models

• Flocculent settling (dynamic)

???? Sidestream & Pre‑Treatment

• Primary clarifiers (BOD/COD removal, TSS removal)

• Thickening, dewatering, centrate return, reject water

• Anaerobic digestion (biogas production – optional module)

????️ Aeration & Oxygen Transfer

• Specific oxygen uptake rate (SOUR), OUR, oxygen transfer efficiency (OTE)

• Clean water vs. process water correction (α, β, F)

• Fine bubble / coarse bubble aeration

???? Energy & Greenhouse Gas (N₂O)

• N₂O emission – nitrifier denitrification, AOB pathway

• Pumping & mixing energy (scales with flow)

• Carbon footprint reporting

???? Dynamic vs. Steady‑State

• Steady‑state (design / conceptual)

• Dynamic (time series: diurnal, storm, wet‑weather) – influent load variations, control loop tuning

???? Calibration & Sensitivity
