FlowVexa is a Canadian company based in Calgary, Alberta. Our international experience, built over more than 25 years in water, wastewater and desalination, including about ten and a half years in Saudi Arabia's Eastern Region, now supports new projects and our work to digitize the assets that make plants run. Digitizing an asset well starts with knowing how it behaves in service.
FlowVexa operates from a Canadian base, backed by hands-on international experience in the Saudi Arabian water industry. Our founder, Hassan Elsheikh, has more than 25 years of experience in water and wastewater, and a significant part of that career was spent in the Kingdom.
That includes about ten and a half years with WETICO / Saudi Berkefeld in Khobar, where he served as Sales Manager, Eastern Region. A regional sales role in water treatment is a technical job as much as a commercial one. It means qualifying a requirement, choosing a process that fits the water and the site, shaping a proposal that an evaluator can compare fairly, and keeping a relationship alive through a project cycle that can run for years.
We bring that experience to every engagement. It shapes how we read a specification, how we explain technology options to a client, which assets we suggest digitizing first, and how we think about the people who will operate the plant after the contractors have left.
Founder & Technical Consultant
How water projects in the Kingdom are initiated, evaluated and procured, and which stakeholders shape each decision, from end users to consultants and contractors.
Proposals that respond to the specification, state their assumptions and show how performance will be demonstrated, clear enough for an evaluator to compare fairly.
Matching the process to the feed water, the quality target and the operating context, and weighing energy, chemicals, maintenance and local support alongside capital cost.
Water projects run for years. Long-standing professional relationships with clients, consultants, contractors and suppliers make that journey smoother.
Areas of expertise
Our wider professional experience covers water treatment, wastewater, desalination and digital transformation. Three areas of work in Saudi Arabia are worth singling out, because they show the range between process engineering and day-to-day plant operation. That operating knowledge is what makes digitalization work in real plants: an asset is digitized well only by people who know how it fails.
Greywater is the relatively light wastewater from sinks, showers and laundry. Treated properly, it can be reused for non-potable purposes such as irrigation, which reduces demand on freshwater supplies. Our experience includes greywater treatment plants in Saudi Arabia, where reuse is a practical way to stretch scarce water.
Crops and nursery stock are sensitive to the salinity of their irrigation water. Where the available source is brackish, desalination turns it into water that crops can tolerate. Our experience includes desalination systems for agricultural and nursery applications in Saudi Arabia.
An RO plant rewards the people who maintain it: membrane cleaning, pretreatment upkeep, pump and instrument care, and trend-based troubleshooting. Our experience includes maintenance activities across multiple desalination facilities in Saudi Arabia, which gives us a practical view of how plants perform after commissioning, and of which signals are worth digitizing.
These highlights describe the type of work our experience covers. They are not a list of named projects. Verified case studies will be added as client approvals are confirmed.
Filtration, chemical dosing and pumping for potable and process water, with the instrumentation to prove the water leaving the plant is on specification.
Municipal and industrial treatment, including biological processes, where steady operation depends on knowing what is happening inside the plant.
Treatment of process effluent so that industrial sites can meet discharge requirements or reuse water on site.
Membrane systems for brackish, process and seawater feeds, from pretreatment through membranes to product-water quality.
SWRO plants face high salinity, variable feed quality and heavy pretreatment demands. Our experience also underpins the Port Sudan initiative below.
BWRO systems turn brackish groundwater into usable water for industry, agriculture and communities, at lower energy intensity than seawater plants.
Compact treatment trains for sink, shower and laundry water, aimed at safe non-potable reuse. An experience highlight from Saudi Arabia.
Desalination matched to irrigation and nursery needs, where salinity targets are set by the crop rather than by a drinking-water standard.
Routine and corrective maintenance across multiple desalination facilities, with attention to membranes, pretreatment, pumps and instruments.
PLC-based control and instrumentation that keeps treatment processes stable and gives operators clear status and alarms.
Supervisory systems that bring field data to the control room, with trends, alarms and reports built around how the plant is actually run.
Existing infrastructure digitized, with dashboards, KPIs and analytics layered on top, so operational data becomes something people can act on.
Digitizing pumps, meters, tanks and analyzers for remote monitoring, including long-range LoRaWAN links for distributed assets.
In development / Proposed
FlowVexa is involved in the development of water-sector opportunities in Sudan, including a proposed 50,000 m³/day seawater reverse osmosis (SWRO) project in Port Sudan. The initiative builds on earlier professional involvement in Port Sudan water infrastructure.
This is a proposed project. It is not a delivered plant, and nothing on this page should be read as a statement that construction or commissioning has taken place.
Intake design, feed temperature and the quality of the raw seawater drive every downstream decision. Measured feed data, not assumptions, should set the design basis.
Higher salinity raises osmotic pressure, which affects feed pressure, recovery and specific energy use. It also tightens the margin on membrane and materials selection.
Suspended solids, organics and biological activity foul membranes. The pretreatment train is chosen from the seawater quality and the intake type, and it protects both output and membrane life.
Targets follow the end use and the applicable standards. Permeate usually needs post-treatment, such as pH adjustment, remineralization and disinfection, before it enters supply.
Process design, hydraulic and electrical basis, and the technical documentation that lets others evaluate and build the plant.
Sourcing major equipment and materials against specification, with attention to lead times, spares and local support.
Pumps, membranes, vessels, instrumentation and control equipment selected for the duty and the environment.
Mechanical, electrical and instrumentation installation, coordinated so the plant can be tested in logical stages.
Start-up, performance verification and operator handover, so the plant is proven against the quality and capacity it was designed for.
The works around the plant that make it usable, such as intake and outfall, power connection, storage and pumping to the network. Scope is confirmed as the project develops.
For a coastal city, the sea is the one large water source that does not depend on rainfall.
Cities on arid or semi-arid coasts often have limited freshwater, brackish groundwater and surface supplies that vary with the seasons. Seawater desalination gives them a supply that is independent of rainfall, which matters for public health, hospitals, hotels, industry and the port itself.
It is not free of trade-offs. Desalination uses energy, produces a concentrate stream that has to be managed responsibly, and depends on trained operators and a dependable supply of spare parts and membranes. That is why we treat a plant of this kind as a long-term operating asset rather than a one-time equipment package, and why monitoring, maintenance planning and operator training belong in the conversation from the start.
The aim of the Port Sudan Water Initiative is to support reliable, sustainable water infrastructure, building on earlier professional involvement in the city's water sector.
Large desalination plants move through a recognizable sequence of phases. The Port Sudan initiative is at the development end of that sequence.
The phases below describe a general project-development sequence. They are not a schedule, and no dates are implied.
Define the need, the target capacity and the rough shape of the solution.
Test the concept against site, feed-water data, energy supply, environmental considerations and funding.
Develop the process and engineering design, and fix the specification and performance guarantees.
Select suppliers and contractors, and place orders for long-lead equipment.
Build the civil works, install the equipment and complete the supporting infrastructure.
Start up, verify performance and quality, and hand over to operators.
Run the plant, monitor performance, maintain membranes and equipment, and keep the people trained.
Successful water projects need more than good technology. They need someone to find the real opportunity, understand the client, shape the solution and carry it through to a credible proposal. That is why FlowVexa can act as both a technical partner and a business-development partner in the same conversation.
Find the project and understand the client.
Turn the need into a clear technical direction.
Build a proposal that stands up to evaluation.
Keep the project moving once it is awarded.
FlowVexa is based in Calgary, Alberta, with an international perspective built on experience in Saudi Arabia and the wider water sector.
We intend to serve Canadian municipalities, water and wastewater utilities and industry, where the same questions arise: how to digitize aging or distributed infrastructure so its data can be reached remotely, how to extend existing control systems, and how to train the people who run them. We are not claiming Canadian project references here. We are describing where we want to work and what we bring to it.
We also aim to connect Canadian innovation and technology capabilities with water and infrastructure opportunities in international markets.
Tell us what you are working on, in Canada or abroad. We will give you an honest view of the technology options, what is worth digitizing, the market and the next sensible step.
