Process fit
Stability under variability, failure modes under upset, and recoverability after excursions. We look at how options behave when the plant is not in textbook conditions.

Technology & Equipment Fit
Consulting & Design · Baseline → Requirements → Fit → Procurement → Delivery support
On paper, many technologies look suitable. The main question is whether they fit your site conditions, available space, operator capacity and performance goals.
This stage checks that early, before suppliers are compared in detail or design work moves too far ahead.
We set the operating range each option must handle, the site limits it must fit within, and the supplier information needed for a fair comparison. That gives you a shortlist based on what can actually be built and run, not just what looks good on a datasheet.

Technology & equipment fit
We translate performance targets and site constraints into a clear shortlist, setting connection points, supplier checks and operator needs so vendors design, price and respond on the same basis.
SET key constraints
SET connections + ranges
CHECKS performance criteria + supplier information
DE‑RISK “brochure fit” outcomes
Where projects fail
Shortlists can miss physical and operating limits, such as footprint, headloss, connections or maintainability, and the chosen package becomes hard to build or run.
What we set
- Fit constraints, including space, headloss, access and shutdown periods.
- Operator capacity (simplicity, spares, maintenance load).
- Supplier checks, including KPIs, sampling points and performance criteria.
How it changes delivery
Vendors price to the same boundaries and performance criteria. Comparisons become fair, connection points are clearer, and commissioning checks are set early.
Scope boundary
We define the process-side fit criteria for selection, including the operating range, site limits, operator capacity, and the information suppliers must provide to show that a proposed solution is suitable for the duty.

Select by operating range, KPI and supplier information
Keep selection independent: define operating ranges and KPI expectations first, then compare options and vendors against the same rules.
Fit logic
Match needs to technologies - not technologies to needs
Technology selection is often treated like a shortlist exercise. We treat it as a fit problem: which options survive your operating range, constraints, residuals and verification requirements.
Before we talk about specific technologies, we clarify how the plant has to behave across flows, loads, seasons and operating scenarios. That behaviour becomes the reference point for technology fit.
Barrier fit
Where reuse is involved, we test upstream stability, fouling and scaling risks, and how performance will be verified at the barrier.
Operational fit
Control complexity, operator workload, maintainability, spares and response time to upsets. We ask what it will actually feel like to run the plant day-to-day.
Integration fit
Connections, footprint, hydraulics, odor / vent handling, residuals handling and constructability. This is where technology decisions are aligned with your site conditions.
Evaluation
A comparable evaluation approach (so bids are not marketing competitions)
We build scorecards that force comparability on the things that drive outcomes: performance commitments, OPEX assumptions, automation scope, commissioning plan and documentation.
The goal is not to over-engineer the tender. It is to make sure that when you compare options, you are comparing like-for-like operating ranges, not just headline CAPEX or marketing claims.
Comparable assumptions
Energy price, chemical regime, cleaning frequency, sludge disposal route and other key operating assumptions are normalised before bids are scored.
Performance commitments
What is guaranteed, under what operating range and for how long. This keeps outcome and compliance at the centre of the decision, not just installed hardware.
Commissioning commitments
Stabilisation plans, test periods, operator preparation and handover expectations are made explicit, so they can be priced and scheduled rather than assumed.
Documentation commitments
Control description, I/O list, O&M manuals, spares and as-builts - logged as deliverables so they do not disappear when projects get busy.
Technology families
Technology families we work with
We do not promote a single proprietary technology. Instead, we work across a set of proven families and combinations that can be configured for STP, ETP, greywater, vehicle wash, laundry and biosolids streams.
- Group technologies into families instead of single products, so options stay open while decisions stay practical.
- Focus on proven, reference-backed combinations that work for STP, ETP, greywater, vehicle wash, laundry and biosolids.
Chemical treatment & enhanced pre-treatment
Chemically enhanced pre-treatment, pH correction and batch treatment blocks that support heavy metals removal, colour reduction or other specific industrial contaminants.
Biological treatment - MBBR-based and hybrids
MBBR / IFAS-type systems combined with activated sludge or clarifiers, used for STP and many ETP upgrades where compact, robust biology is needed with stable performance.
Solid-liquid separation - DAF, lamella, clarifiers
Dissolved air flotation, lamella settlers and clarifiers for primary or secondary separation in industrial ETPs, retrofits or where better solids capture is required.
Filtration - dead-end and crossflow
Media, cartridge and other dead-end filters used for polishing before reuse, and crossflow filters supporting UF / NF / RO where higher pressures and fouling control matter.
Membrane-based reuse & desalination
UF, NF and RO treatment lines for reuse and desalination, including high-TDS segments that must be coordinated with brine and ZLD logic rather than treated in isolation.
Evaporators & ZLD systems
Mechanical vapour recompression (MVR) evaporators, concentrators and crystallisers used where brine or high‑TDS streams must be reduced to a manageable solid or near‑zero liquid discharge, coordinated with upstream RO and chemical treatment.
Advanced oxidation and polishing
Advanced oxidation and polishing steps (AOP, ozone, UV and similar) used where the risk profile, reuse class or contaminant mix genuinely justifies the additional complexity.
Biosolids dewatering & thickening
Decanter centrifuges, belt presses, screw presses and filter presses for taking sludge from liquid handling to cake, lowering volumes and preparing material for drying, composting or further treatment.
Drying, composting & fertiliser enhancement
Low‑rate and high‑rate dryers, composting lines and enhancement steps that turn stabilised sludge into organo‑mineral fertiliser or biofertiliser products with defined quality and routes to market.
Operating ranges
Technology operating ranges for site streams
For each type of plant and stream, we outline viable technology families and where they fit in the process - biological, physical-chemical, membrane-based and biosolids pathways.
- Map where each family performs reliably in terms of flows, loads, TDS and variability.
- Show how treatment steps line up with compliance, reuse and, where relevant, ZLD or brine-handling needs.
Liquid treatment lines
Combinations of headworks, biological treatment (e.g. MBBR hybrids, conventional activated sludge), clarification, filtration, disinfection and, where needed, membrane and advanced polishing steps.
Biosolids and side-streams
Dewatering, drying, composting and fertiliser / biofertiliser routes for sludge and biosolids, and appropriate handling for concentrates, brines and high-strength side streams.
Equipment blocks
Equipment blocks and configuration
We then break proposed treatment lines into practical equipment blocks that vendors recognise - making it easier to compare offers later without losing sight of the process logic.
- Translate process logic into equipment blocks and packages that vendors recognise and can price.
- Highlight which blocks are essential today and which can be staged or made future-ready.
Core process units
Screens, grit and grease removal, DAF and clarifiers, filters, membrane racks, reactors and contact tanks sized for flows, loads and the variability we have already mapped.
Dosing, disinfection & ancillaries
Chemical dosing systems, disinfection units, blowers, pumps, mixers and storage tanks, linked to realistic control philosophies and maintenance expectations.
Sludge and biosolids handling
Thickeners, dewatering presses, dryers and associated conveying, storage and loading equipment sized to support chosen biosolids pathways and logistics.
Site streams
Streams we typically work with
Across all our specialist design work, we focus on operating plants and facilities handling:
STP - Municipal / domestic sewage
ETP - Industrial / trade effluent
GWTP - Greywater treatment
VWRP - Vehicle wash water
LWRP - Laundry wash water
Biosolids & sludge to resource recovery
Selection criteria
KPIs, operating checks and selection criteria
For each major block and treatment line, we define the KPIs and operating checks that matter - so technology and equipment choices can be compared fairly and transparently when you go to market.
- Turn process and compliance needs into a handful of measurable KPIs and target ranges.
- Define simple, transparent selection logic so vendor proposals can be compared on more than just unit price.
Performance and operational KPIs
Effluent quality criteria, recovery percentages, specific energy and chemical use, uptime, cleaning frequency and operator attention requirements agreed upfront.
Pre-sourcing selection logic
Criteria to screen technology and equipment families before detailed vendor engagement, keeping options open where useful but avoiding unmanageable complexity.
Example systems
Example specialist systems we often design
To make the technology families more concrete, these are typical system configurations we help owners develop. They are not products - they are examples of how we combine blocks to solve practical problems.
Preparing for vendor-facing specifications
By the end of this focus area we have a clear, documented view of which technologies and equipment blocks make sense, and how their performance will be judged. This becomes the bridge into vendor-neutral specifications and the sourcing advisory work.
Compact MBBR-based STP upgrade with TSE reuse
For municipal or campus plants with limited space and rising reuse demand. Headworks → MBBR bioreactor → clarifier / DAF → filtration → disinfection, delivering stable compliance and defined TSE classes for landscaping or cooling.
Industrial ETP with DAF + MBBR + membranes
For food & beverage or light industrial sites. Equalisation → DAF / lamella → MBBR → clarification → filtration / UF → reuse or safe discharge, reducing surcharges and improving sludge handling.
Greywater treatment package (GWTP)
For residential or mixed-use buildings and campuses. Screening → biological treatment → filtration → disinfection to supply non-potable uses such as flushing and irrigation, reducing fresh water demand.
Vehicle wash water reuse skid (VWRP)
For fleets, depots and car washes. Solids removal → oil separation → filtration → partial reuse, lowering water purchase and discharge volumes while keeping layout compact.
Laundry water recycling (LWRP)
For commercial laundries and hospitals. Equalisation → filtration → membrane treatment → partial reuse in washing stages, with careful attention to chemistry and fabric care constraints.
Biosolids to compost / biofertiliser
For STPs or combined plants. Dewatering → drying / stabilisation → composting or organo- / biofertiliser processing, reducing disposal costs and enabling beneficial use where feasible.
Procurement support
Support through procurement without duplicating the vendor's role
Our role is to keep the decision basis intact through procurement: preserve comparability, prevent scope drift and ensure the commissioning obligations remain in the contract package.
Bid alignment workshops
Walk vendors through the operating range, requirements and verification expectations so that misunderstandings are identified before award.
Contract-ready performance clauses
Target ranges, documentation deliverables, operator preparation and verification reporting obligations are translated into language that can fit cleanly in your contracts.
Outputs & deliverables
What you receive from the technology-fit pathway
The outcome of this pathway is a structured view of which technology families and equipment configurations can truly work on your site - with a clear paper trail that can be handed straight into sourcing or implementation.
Fit & options memo
Shortlist with rationale against constraints, operating range, residuals and verification needs. Captures why options stay in or out.
Vendor scorecard
Comparable scoring criteria with weightings and a basis for recommendation that can be reused across future tenders.
Clarifications & bid Q&A pack
Structured questions that expose hidden scope and incompatible assumptions, so bidders respond inside the same operating picture.
Risk / assumptions register
Assumptions logged with verification actions and owner / vendor responsibilities, so there is a home for uncertainty instead of it being ignored.
Next step
From design targets to technology fit and integration
This view comes between requirements and integration. Once reuse logic, regulatory drivers and value opportunities are translated into design targets, we use technology fit to narrow in on credible technology families and equipment blocks that can actually meet those targets on your site.
The next step is Integration & automation, where operating ranges, KPIs and information requests are carried through into how packages connect, how control and monitoring are set up, and how vendor proposals are structured so delivery partners can execute reliably.
