All sections

The complete table of contents. If you are new, the guide overview is a better starting point — it has the three pages to read first and a route by task.

Drawing and templates

• Drawing — the P&ID editor. Creating a drawing · drawing and connecting · client standards · comments and markers · server-side validation · continuation states · background images · touch and pen · tips and troubleshooting
• Bringing drawings in — importing a P&ID, reviewing recognition results, identifying hotspots. CAD import is deterministic — blocks and layers map to symbols through a mapping table you control. Recognition of a scanned drawing is assisted, not automatic: it proposes symbols for you to confirm, and the review pages above are part of the job rather than an optional check.
• Drawing Templates — parametric, code-described P&ID building blocks. Overview · pumping stations · instrumentation arrangements · intermediate pumping station worked example · template language reference · engine internals
• Plant Templates — the library of pre-built plant configurations (a separate thing from drawing templates above).

Simulation

• Simulation overview · building a flowsheet · calculation modes · steady-state · dynamic · model selection · controllers in a flowsheet · biogas production
• Biokinetic models — ASM1, ASM2d, ASM3, ADM1, Sumo2N
• Mass balance — COD fractionation, nitrogen, phosphorus
• Settling — Takács settling model

Process units

Every documented unit, by category. The two naming schemes below are a known duplication in this tree — see documentation coverage.

Category	Pages
Preliminary treatment	9 units — screens, grit, grease · also screens, grit removal, flow measurement
Primary treatment	circular, rectangular, lamella · also primary clarifier, CEPT
Biological treatment	activated sludge, biofilm systems, anaerobic, zones — 24 pages
Secondary treatment	clarification · also activated sludge, MBR, MBBR, SBR, trickling filter
Tertiary treatment	filtration, disinfection, membranes
Sludge treatment	thickening, digestion, dewatering — 16 pages
Chemical dosing	no pages yet — see coverage

Design and engineering

• Design Calculations — flow and load · primary tanks · biofilters · humus tanks · sludge production · chemical dosing · alkalinity balance · parameter help
• Controllers — control types (cascade, ratio, deadband, switch, time on/off, continuous P, feedforward) and the loops they serve (aeration, DO, RAS/WAS, SRT, pH and alkalinity)
• Hydraulics — steady-state pipe-network solution with Hazen-Williams or Darcy-Weisbach head loss, drawn back onto the drawing
• Safety Analysis — HAZOP (guideword deviations, with a deterministic Auto-analyze) · FMEA (live RPN and AIAG-VDA action priority) · SIL (PFD_avg per voting architecture) · LOPA (independent protection layers and required SIL) · DSEAR (hazardous-area zones and ATEX category)

Delivery and commercial

• Bill of Materials — how the BOM stays in sync with the drawing, the detail view, statuses, export
• Planning — the Gantt and critical path, levelling, baselines, earned value · schedules
• Carbon Footprint — using the Carbon tab · GHG emissions · Scope 1/2/3 · biogas production · energy recovery · reporting
• Collaboration — live editing and offline sync · notifications
• Workflows — routing work for review · building a template
