Clean water, engineered to flow.
FLOW AQUA designs, builds and runs water and wastewater treatment plants for industry and municipalities, from raw materials to after-sale support.


Built by water treatment specialists.
FLOW AQUA B.V. was founded by experienced water treatment professionals. Our headquarters is in Leeuwarden, the Netherlands, and our engineers in Amman design and produce our products for the Middle East and North Africa.
We follow every step ourselves, from raw materials to after-sale support, because that is how we guarantee quality.
MissionMake life easier for professionals and companies through knowledge, innovation and know-how applied to the evolution of our technologies and processes.
One line from sketch to operation.
Every plant follows the same six stages, handled by one team. Scroll and the line fills as the work moves forward.
- 01
Design
Process selection, mass balance and layout from your water analysis.
- 02
Engineering
P&IDs, hydraulic sizing, electrical and control philosophy.
- 03
Manufacturing
Skids, panels and tanks built and tested before shipping.
- 04
Installation
Mechanical, electrical and civil interfaces completed on site.
- 05
Commissioning
Start-up, performance testing and operator training.
- 06
Operation & maintenance
Running contracts, spares and chemicals for the plant's life.
Consultancy runs alongside every stage: feasibility studies, plant audits and upgrade plans.
Treatment for every stream.
For every water treatment problem we design the most suitable solution, technically, ecologically and economically.
Industrial wastewater
Aerobic plants remove organic load, nitrogen and phosphorus. When organic load is high, anaerobic treatment produces energy-rich biogas for steam or power. Our track record counts more than 400 industrial references.
Municipal wastewater
Biological plants for towns and communities, from pre-treatment through sludge and odour treatment, producing water safe for discharge or irrigation. Also supplied as compact and containerized units.
Drinking water
Compact plants combining cascade aeration, coagulation, flocculation, lamella settling and sand filtration, or UF and RO membrane plants for brackish, sea, ground and surface water.
Process water
Our membrane filtration produces tailor-made process water from any source and closes the water loop, turning biological effluent into potable and process quality.
Water reuse
We combine wastewater, process and drinking water technologies so treated water returns to production, irrigation, groundwater recharge or even drinking water.
Desalination
RO membrane technology for efficient, economical drinking and process water from brackish and sea water, with more than 50 BWRO references in industry.
Disinfection systems
UV systems, ozone and chlorine dioxide generators, salt and gas chlorinators, supplied with all safety, measuring and control instrumentation.
Equipment for every treatment step.
Sixteen product families, from inlet screens to final disinfection. Open any one to see the full range.
Photos show supplied equipment and installations. Two families use illustrative renders.
Plants built and running.
Twelve reference plants in Jordan, Qatar and Saudi Arabia, from a 25 m³/day sewage unit to a 26,000 m³/day industrial plant.
Capacity by project, m³/day
Bar length on a log scale, so small and large plants both stay readable.
