I need a full technical design package for a seawater reverse-osmosis (SWRO) plant that will supply industrial-grade water at a moderate purity level. Target production is in the 1,000–10,000 m³/day range, and the system must incorporate a pressure exchanger (PX) for energy recovery. Here is what I expect: • Process & instrumentation diagram (P&ID) and overall process flow diagram sized for the stated capacity • Mass and energy balances that clearly show the impact of the PX device and the resulting specific energy consumption • Equipment sizing and datasheets for high-pressure pumps, membranes, pressure vessels, PX unit, chemical dosing, and post-treatment • Operating philosophy, start-up/shutdown sequence, and control logic narrative • Bill of materials with indicative specifications ready for vendor inquiry • Brief technical memo summarising projected permeate quality, recovery rate, and expected operating costs Acceptance is based on consistency across all documents, adherence to industrial water quality targets, and demonstration of energy savings through the PX configuration. AutoCAD (or similar) for drawings and any recognised RO design software such as IMSDesign/ROSA/WinFlow are fine; please state the tools you use so I can easily review native files. Send any clarifying questions early so the design can move forward quickly.

Having designed several industrial-scale SWRO systems ranging from 500 to 5,000 m3/day, I understand the critical balance between energy recovery efficiency and membrane longevity in high-salinity environments. My previous work includes delivering comprehensive process flow diagrams and rigorous mass balance calculations for coastal facilities, ensuring strict compliance with environmental discharge regulations for brine management. I am ready to translate your specific capacity requirements into a robust, scalable engineering package using industry-standard simulation tools and validated thermodynamic process modeling. My technical approach begins with a detailed chemical analysis of the feed water to determine the optimal pretreatment sequence, likely incorporating ultrafiltration to minimize the Silt Density Index (SDI) and protect the downstream high-pressure components. I will utilize DuPont WAVE or LG Q+ software to model the membrane array, selecting high-rejection SWRO elements while integrating Energy Recovery Devices (ERDs) like isobaric chambers to reduce operational power consumption by up to 40%. The final package will include a comprehensive P&ID, detailed equipment specifications for high-pressure pumps and Duplex steel piping, and a precise chemical dosing strategy to prevent inorganic scaling and organic biofouling during continuous operation. To tailor the design, what is the specific Total Dissolved Solids (TDS) concentration and temperature range of the source water? I’d also like to know if you have a preferred vendor for the PLC/SCADA integration or if you’d like me to recommend a high-reliability, vendor-neutral control architecture. Let’s connect for a brief chat to align on the technical milestones and delivery timeline—I am available to discuss the specifics via message or call whenever you’re ready.

I am a Process Engineer currently working in industrial water treatment, specifically in chemical dosing and reverse osmosis systems. My daily work involves mass and energy balances, RO performance evaluation, and technical development of process documentation. For your SWRO plant (1,000–10,000 m³/day), I can deliver a fully consistent technical design package including PFD, P&ID (AutoCAD Plant 3D), detailed mass and energy balances, and equipment sizing based on Winflows (Veolia’s RO design software). This ensures realistic membrane projection, recovery optimization, and accurate specific energy consumption calculations incorporating the PX energy recovery device. Because I work directly with RO systems in real industrial environments, my designs prioritize operability, chemical control strategy, energy efficiency, and vendor-ready documentation. I can structure the work in clear milestones and begin with a confirmed design basis to ensure alignment before developing the full package. I’m available to clarify seawater characteristics, permeate targets, and recovery assumptions to move forward efficiently. Best regards, Kevin Segovia
