Nereda® technology from Royal HaskoningDHV offers sustainable wastewater treatment solutions for municipal and industrial water. The natural sewage treatment process purifies water with minimal or no chemical usage by using the patented aerobic granular sludge technology. Compared to activated sludge technologies, the biological treatment power of the technology is much larger, while saving up to 50% on energy costs, delivering high quality effluent for low costs and requiring only a quarter of the area of conventional activated sludge installations. Biomass in the process develops as fast settling aerobic granular sludge. These granules have excellent settling properties, so the process does not require a separate time-consuming decant phase like conventional SBR’s. All the biological treatment processes take place simultaneously in the granules, requiring only one tank. The technology is very versatile; it can be developed as a new build or used to retrofit existing conventional CAS or SBR plants. The benefits of the technology include: Excellent treatment results and settling properties: Compared to activated sludge technologies, the biological treatment power of the technology is much larger as a considerably higher concentration of biological active mass is applied that in addition has a much higher content of microorganism that are crucial for biological nitrogen and phosphate removal. Sustainable: Compared to conventional wastewater treatment processes, the technology not only has significantly lower energy consumption and associated greenhouse gas emission, but also produces, commonly without the use of waste generating chemicals, a remarkably high effluent quality. Cost effective: The technology results in construction costs that are lower than for conventional technology as for example, tank volumes are up to four times smaller and less equipment is required. Small physical footprint: Its footprint at sewage treatment plants is reduced due to the full nutrient removal process taking place in one single reactor. Easy to operate: It has proved in operation to satisfy the most stringent purification requirements. Thanks to the nature of the technology, plant operation is easy and process performance robust. The technology is proven and applicable for even the largest applications. Currently, there are over 70 wastewater treatment plants in operation or under construction all over the world

Liquid X is a water technology consultancy and commercialization platform focused on accelerating the deployment of next-generation filtration solutions, with a core emphasis on graphene-based water treatment. Founded to address the gap between breakthrough innovation and real-world implementation, Liquid X operates at the intersection of advanced material science, water infrastructure, and market deployment. While significant advances in water technologies exist globally, many remain confined to laboratories or early-stage ventures. Liquid X bridges this gap by identifying, validating, and commercializing high-impact solutions—particularly graphene-based filtration systems—within the GCC and wider MENA region. Our consultancy model is built around a full lifecycle approach: from technology scouting and technical evaluation to pilot design, validation, and scaled deployment. We work with asset owners, governments, and enterprises to translate emerging technologies into practical, site-ready solutions. This includes designing pilot programs with measurable performance metrics, enabling data-driven decision-making, and ensuring that innovations are proven under real operating conditions before scale-up. A key focus of Liquid X is the commercialization of graphene-based water filters. Graphene, a two-dimensional material with exceptional strength, permeability, and adsorption capacity, has the potential to fundamentally transform water treatment. Its nano-scale structure allows precise separation of contaminants while enabling faster water flow and lower energy consumption compared to conventional systems. Through strategic partnerships with innovators, researchers, and manufacturers, Liquid X is actively working to bring graphene filtration technologies from concept to market. These systems are being developed to address some of the most critical water challenges, including the removal of PFAS and emerging contaminants, heavy metals, dissolved solids, and industrial pollutants—while significantly reducing waste and energy intensity associated with traditional technologies such as reverse osmosis. Our role extends beyond technology development. Liquid X supports the full commercialization journey, including: Technical due diligence and performance validation Pilot implementation and third-party verification Integration with existing infrastructure Development of scalable deployment models Coordination with EPC contractors, facility managers, and regulators Ongoing monitoring, compliance, and optimization By operating as a vendor-agnostic platform, we ensure that solutions are selected based on performance, suitability, and long-term value—not vendor bias. The MENA region faces some of the world’s most acute water challenges, including scarcity, high desalination dependence, and rising energy costs. Liquid X is positioned to introduce more efficient, decentralized, and sustainable alternatives through advanced filtration technologies. Graphene-based systems, in particular, offer the potential for lightweight, modular, and energy-efficient treatment solutions that can be deployed at scale across residential, commercial, and industrial applications. At its core, Liquid X is not just a consultancy—it is an enabler of the next generation of water infrastructure. By combining deep regional expertise with global innovation networks, we are helping transform how water is treated, distributed, and consumed. Our mission is to accelerate the transition from legacy, resource-intensive systems to smarter, more sustainable water solutions—unlocking the full potential of graphene and other advanced materials to build a more water-secure future.
