Vaucluse Water Treatment Works

A 42 Ml/d municipal drinking-water works: raw-water intake, coagulation, three ultrafiltration skids, UV and chlorine disinfection, clearwell storage and pressure-managed distribution.

The Vaucluse Water Treatment Works process overview in Djinious: raw-water pumps, intake valve, three ultrafiltration skids, UV reactor, chlorine dosing, clearwell and three distribution pumps, with live flows on every line.

What the platform models here

Each family has a behavioural model that the live simulator and the proving twin share, so a dry-run behaves the way the plant does.

THE STANDING PROBLEM

A fouled membrane skid is a compliance problem, not a maintenance ticket

UF-03 runs at a fouling index of 61 %, holding transmembrane pressure at 1.60 bar — past the 1.35 bar backwash limit. Take it out of service naively and the works loses a third of its treated-water capacity during peak demand. Leave it fouled and permeate turbidity climbs toward the membrane-integrity limit.

THE PROCEDURE

Ultrafiltration Backwash & Load Transfer

uf-backwash-recovery

Recover a fouled ultrafiltration skid without losing treated-water output: take UF-03 off duty and backwash it, transfer its load to UF-01 and UF-02, and confirm with the treatment supervisor before the change is applied.

  1. 01Reduce UF-03 flux → 40 %
  2. 02Backwash UF-03
  3. 03Raise UF-01 flux → 96 %
  4. 04Raise UF-02 flux → 96 %
  5. 05Treatment-supervisor confirmation
  6. 06Notify control room

THE PROOF

UF-03 Fouling Excursion

UF-03 enters the shift already fouled and continues to foul while the other two skids run at normal flux.

Baseline fails both assertions. With the procedure, four commands are intercepted on the isolated twin and both hold.

IN THE PRODUCT

What the control room sees

The Djinious operator dashboard scoped to the water works: asset counts, availability, active alarms, a live trend of works output and distribution flows, and the plant status grid by equipment family.
The dashboard adapts to the plant. No generation here, so the KPI row is assets, availability and alarms — and the hero trend is the works' own signals.
The Djinious alarm list showing ISA-18.2 priorities, states and acknowledgement controls.
ISA-18.2 alarm management. UF-03's transmembrane pressure alarm is a real threshold crossing on a real tag.

The procedure as the platform holds it: BPMN, validated, with its required capabilities and authority class.
