Wastewater Plant Design Pro is a professional engineering platform for the design, validation, and benchmarking of wastewater treatment plants. Built with deterministic, audit-ready logic, it integrates process engineering, compliance validation, and sustainability modeling into one package — making it a practical alternative to multi-thousand-dollar desktop software. 🔑 Key Features Influent & Plant Inputs – Define site-specific flow, temperature, pH, BOD₅, COD, nutrients, and solids. Microbiology & Risk Analysis – Quantify E. coli, coliforms, and helminth eggs, with real-time microbial risk heatmaps. Regulatory Design Criteria – Benchmark against EPA (US), EU Urban Waste Water Directive, WHO, ISO 30500, and regional/custom standards. Treatment Train Builder – Configure complete systems: screening, clarifiers, DAF, lamella, MLE, A²O, MBBR, MBR, sand/membrane filtration, and disinfection (UV, chlorine, ozone). Sludge & Energy Models – Predict sludge production, dewatering volumes, anaerobic digestion, struvite recovery, and energy recovery vs. demand balance. Mass Balance & Unit Sizing – Real-time removal efficiencies, graphical mass balance plots, and automated sizing of clarifiers, aeration tanks, and DAF units. Compliance Dashboard – Instant permit readiness scoring, sensitivity analysis, and effluent target validation. Cost & Carbon Accounting – Detailed OPEX estimates (energy, chemicals, sludge, maintenance) and carbon footprint with benchmarking (kg CO₂/m³). Scenario Comparison – Compare alternative treatment strategies (A vs B) for planning and regulatory submissions. Reporting – One-click export of permit-ready PDF summaries including design, compliance, and sustainability results. 🎯 Designed For Environmental and civil engineers designing WWTPs and retrofits. Regulators validating compliance with international discharge/reuse standards. Consultants and ESG professionals quantifying carbon intensity and sustainability impacts.
