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.

EC Solutions is a specialized consultancy focused on electrochemical technologies for water and wastewater treatment. We believe electrochemical processes, and electrocoagulation in particular, are among the most promising technologies in the water sector today. As a rule of thumb, anything that can be treated with conventional coagulation–flocculation can be pretreated with electrocoagulation, without adding chemicals. That means less chemical handling, lower sludge complexity, and more controllable treatment outcomes. We help industries evaluate, pilot, and implement electrocoagulation as a robust pretreatment or core process for color removal, heavy metals, TSS, emulsified oils, and complex industrial effluents. If you’re dealing with a difficult water challenge and want a cleaner, smarter alternative to chemical treatment, EC Solutions is built for that.
