Services across the plant lifecycle

Analysis, redesign, restructuring, AMC, operation, chemicals and optimisation, from one engineering team.

Detailed analysis and redesign

We do not guess why a plant is underperforming. We measure it, find the cause and design the fix.

Brief and dataDesign basis, as-built drawings, operating logs, consent conditions
Site auditTanks, equipment, aeration, hydraulics, sludge handling, electrical and controls
Sampling and analysisSamples at each stage of the train, with laboratory analysis
Load and flow reviewActual load and flow against design basis and future need
Energy and chemicalsPower use of blowers and pumps; chemical consumption and dosing
Findings and optionsRoot causes, options, benefits and trade-offs
Redesign and costingProcess and equipment redesign, scope, cost and schedule

Deliverable: a written report with findings, photographs, data tables, the recommended redesign and a costed scope.

Restructuring existing plants to standard

Many plants can meet the current norm without being replaced. Our team restructures existing STPs and ETPs to the standard that applies to them: we keep what works, correct what does not and add what is missing.

Typical issueWhat we do
High BOD or COD in treated waterProcess correction, aeration and biological stage redesign
High suspended solidsClarifier correction, filtration or UF polishing
OdourAeration, layout and process changes
Sludge handling issuesSludge system correction, dewatering upgrade
High power useEnergy audit, efficient blowers and drives, automation
Capacity shortfallMBBR media, membrane or equipment additions to raise capacity in the same tanks
Not meeting current normsUpgrade with tertiary treatment and monitoring, to the applicable standard
Plant not reusing its waterAdd UF, RO or disinfection to bring treated water to reuse quality

We report a before-and-after comparison of treated-water quality, power and chemical use, so the improvement is visible.

AMC contracts

Keeps the plant within its approved performance.

  • Planned preventive maintenance
  • Scheduled inspections
  • Fast breakdown support
  • Scope written to your plant and the standard it must meet

Plant operation and maintenance

AFD operators run your plant, with escalation to our engineers.

  • Daily checks: flows, levels, aeration, pumps, alarms
  • Process control: dissolved oxygen, sludge, recirculation, dosing
  • Routine sampling and records
  • Monthly performance reports
  • Records for consent and audit

Chemical supply

Matched to your process and delivered on schedule.

  • Coagulants and flocculants
  • Polymers for clarification and dewatering
  • Disinfectants
  • Antiscalants and membrane cleaning chemicals
  • pH correction chemicals
  • Biological additives where the process needs them

Chemical optimisation

Chemicals are a running cost that is easy to overspend. We review how they are dosed against the water they treat and adjust dosing to the real load, while keeping treated-water quality within target.

BaselineCurrent chemical consumption and treated-water quality
Dosing reviewPumps, calibration, dosing points and control logic
TrialsJar tests and controlled dose adjustments
Set new dosingFixed dose rates, automatic dosing where it pays
TrackMonthly consumption and quality report

The aim is stable quality at a controlled chemical cost. We report what changed and why.
