Tech Brief: Chemica’s Water Purification Technology comprises specially-designed ligands tethered to a fabric-like material. The base material adsorbs common contaminants while the ligands efficiently "snatch up" organic/inorganic toxins; including arsenic, mercury, lead, cadmium and a broad spectrum of organic chemicals. The adsorbent is robust, lightweight, flexible, scalable and regenerable.


Value Proposition: Chemica's adsorbent quickly and sufficiently removes a broad range of toxic organic compounds (TOCs), including polyaromatic hydrocarbons (PAHs), and toxic inorganic chemicals (TICs), including metals/metalloids, with a simple-lightweight system. In hostile/chaotic environments, including the battlefield, it is possible that some sources of drinking water could be contaminated with unknown toxins, which are not easily identified. Unfortunately, standard water purification technologies that remove a broad range of toxic compounds are quite heavy and composed of several components, and further, are expensive to operate and maintain. Most sorbents used to purify drinking water are unable to adsorb a broad spectrum of toxins with high efficiencies. By utilizing Chemica’s adsorbent, health problems caused by exposure to TOCs and TICs in drinking water can be minimized. Unlike competing technologies, Chemica's adsorbent is highly robust, can withstand shock, vibration, static/dynamic, high heat and freeze/thaw events. Being lightweight, our material is highly portable with no energy or high-pressure requirements. It can be used over several months and regenerated. These features will facilitate a transportable system for use on the battlefield, in remote locations and in emergency scenarios.
