4Earth is an Atlanta-based technology company specializing in advanced water treatment solutions. Founded in 2020 by CEO Jahanzeb Khan, a Georgia Tech-educated engineer, the firm designs, manufactures, and operates smart, modular water treatment systems aimed at enhancing water sustainability.
The company's core offering consists of pre-built, containerized "microplants" that feature a plug-and-play design for easy installation and scalability. These systems utilize a combination of advanced technologies, including membrane filtration, advanced oxidation processes (AOPs), and optimized coagulation to remove a wide range of pollutants. The technology is capable of treating harsh industrial wastewater and removing contaminants such as heavy metals, pharmaceuticals, pesticides, and PFAS. A key feature is the integration of modern UI, advanced analytics, and machine learning to automate and optimize the treatment processes, which helps reduce energy consumption, chemical usage, and operational costs while monitoring for equipment failures.
Khan's background as a former MMA fighter fueled his desire to address the global water crisis, a mission he pursued more directly after studying at Georgia Tech. He identified a dual need in the market: sustainable, user-friendly technologies for developed nations and decentralized infrastructure for developing regions. 4Earth serves clients in both industrial and municipal sectors, with applications ranging from drinking water treatment to industrial wastewater reuse. The company is expanding internationally into markets in Mexico, the MENA region, Africa, and Europe. 4Earth was part of the inaugural cohort of the Cox Cleantech Accelerator in 2025.
