SHIZ Smart Wastewater Treatment Plant Designer

Engineering-Grade Process Synthesis & Mass-Balance Simulation Engine

Welcome to the SHIZ Smart Process & Membrane Sieve-Logic Studio (v7.5)—an advanced, interactive process design platform engineered for municipal and industrial wastewater treatment plant (WWTP) preliminary design. Moving beyond superficial rule-based selection tools, this studio features a fully integrated Mass-Balance Sizing Engine that tracks true pollutant loading rates and models dynamic boundary state transformations across every step of your treatment train.

Dynamic Treatment Train Interlocks

Automated Primary Selector: Evaluates influent grease and particulate matrices in real time. Dissolved Air Flotation (DAF) systems for heavy FOG ( $>100\text{ mg/L}$ ) and immense TSS ( $>400\text{ mg/L}$ ) profiles.
Divergent Biological Kinetics: Differentiates treatment volume demands based on process selection, using true kinetic and yield properties to vary hydraulic retention time (HRT) and biomass inventory requirements across CAS ( $3,500\text{ mg/L}$ MLVSS), MBBR ( $2,000\text{ mg/L}$ biofilm bulk), and MBR ( $8,000\text{ mg/L}$ core array) systems.
Advanced Desalination & Selective Softening: Evaluates ionic chemistry thresholds to choose between low-energy, monovalent-permeable Nanofiltration (NF) or strict solution-diffusion Reverse Osmosis (BWRO), complete with membrane salt leakage and concentrate reject flow modeling.
Oxidant Mitigation Loops: Identifies toxic trace chlorine variables before they reach downstream high-pressure skids, choosing between space-saving Sodium Metabisulfite (SMBS) chemical quenching or Granular Activated Carbon (GAC) adsorption arrays based on organic matrix fractions.

Real-Time Compliance & Secondary Waste Diagnostics

The studio terminates at a rigorous 4-Point Boundary Auditor. This engine assesses system compliance against your exact targets for $\text{BOD}$ , $\text{COD}$ , $\text{TSS}$ , and $\text{TDS}$ simultaneously, preventing false positives and ensuring true process compliance. Additionally, the system continuously monitors internal transformations to provide active operational forecasts, including total Dry Solid Sludge Production ( $\text{kg/day}$ ) and Brine Stream Reject Volume ( $Q_{\text{reject}}$ ) to assist with downstream zero liquid discharge (ZLD) asset planning.

This environment applies generalized chemical and environmental engineering design equations. Rather than applying fixed assumptions for arbitrary values, the system evaluates the thermodynamic and mechanical gaps between your influent characteristics and effluent standards to optimize assets dynamically.
