TOTAL WATERDESIGN SUITE
Part of the Total Water Design Suite
Reverse osmosis design beyond the conventional array.
Conventional RO, True Batch RO, Semi-Batch RO, and eligible energy-recovery configurations from one membrane basis.
Sign in to open Total RO Design →Conventional RO, True Batch RO, Semi-Batch RO, and eligible energy-recovery configurations from one membrane basis.
Flow, temperature, pH, ionic analysis or TDS-only basis, membrane data, arrays, pressure limits, pump/ERD data, and batch or recirculation inventory assumptions.
Stage and element performance, recovery, permeate/concentrate quality, pressure/flux profile, pump and recovered power, SEC, warnings, cycle profile and report snapshot.
Selected membrane and vendor data, stated operating duty and discrete quasi-steady increments for batch modes; full chemistry is needed to review high-recovery scaling.
Engineering review, codes, vendor curves, pretreatment strategy and project-specific verification remain required. TDS-only mass balance does not certify chemistry feasibility.
INTEGRATION ROLE AND MATURITY
Available application in the Suite foundation; automatic whole-train handoffs are not implied.
3–9 h conventional projection; 8–22 h advanced multi-configuration study
Illustrative planning assumption—not a measured customer outcome or guarantee. Actual time depends on project complexity, data quality, current tools, alternatives, review requirements and user experience.
Sample-report library: conventional RO, True Batch, Semi-Batch and brackish ERD examples are version-identified when published. Validated, sanitized sample artifacts are currently unavailable; publication is planned. No downloadable evidence is implied.
RO MODE AND ERD MATURITY
Current: conventional one- to four-stage RO in Total RO Design v0.30. Engineering preview / under validation: True Batch RO, Semi-Batch RO, isobaric exchange, turbo, Pelton and interstage ERD paths. Planned: advanced optimization. Availability does not make every mode or ERD path current.
| Mode | Inventory behavior | Fresh make-up behavior | Engineering boundary |
|---|---|---|---|
| Conventional RO — current | Continuous feed-to-concentrate flow through staged membrane arrays. | Continuous feed forms the operating stream. | Steady operating condition with stated hydraulic, membrane and chemistry assumptions. |
| True Batch RO — preview | Initially charged inventory concentrates as permeate leaves. | No continuous fresh-feed mixing into the concentrating inventory during productive concentration. | Transient inventory with converged quasi-steady increments; not valve dynamics, CFD or fatigue modelling. |
| Semi-Batch RO — under validation | Concentrate recirculates and loop inventory stays approximately constant during recirculation. | Fresh make-up enters while permeate is produced; displacement, recirculation and purge are a complete sequence. | Full chemistry is needed to review high-recovery scaling feasibility. |
Preview paths evaluate brackish-water ERD configurations only where useful concentrate pressure remains available, including multistage isobaric exchange, turbo, Pelton and interstage alternatives. Pump and ERD vendor curves require confirmation.
Entitlement is not engineering eligibility. Feature access does not declare an ERD feasible: pressure, flow, device range, topology and operating constraints must also be satisfied.
