FM AQUA

Molecular media is essential for effective molecular filtration solutions. At First Molecule,we offers a range of proven impregnated activated carbons designed to target a broad spectrum of odours, irritants, toxic, and corrosive gases.

FM AQUA

Water Treatment FM AQUA is a premium Granular Activated Carbon (GAC) specifically developed for the rigorous demands of liquid-phase purification. Sourced from the finest raw materials, its unique activation process creates a highly microporous structure with an exceptional surface area. This design allows it to adsorb a broad spectrum of dissolved organic contaminants, including chlorine, chloramines, disinfection byproducts like Trihalomethanes (THMs), and a myriad of taste and odor compounds. Its consistent particle size ensures optimal hydraulic performance and minimal pressure drop in fixed-bed systems.

Beyond conventional municipal water treatment, FM AQUA is extensively used in industrial process water, wastewater reclamation, and in-home filtration systems, where its high capacity and longevity provide a cost-effective solution for ensuring clean and safe water.

Technical Evaluation & Competitive Advantage

Superior Adsorption Capacity: Our Iodine Number (a measure of micropore volume for small molecule adsorption) consistently exceeds industry standards, often by 10-20%. This means FM AQUA can process a significantly larger volume of water before requiring replacement or regeneration, leading to lower operational expenditures.

Exceptional Attrition Resistance: With an attrition hardness of over 95%, FM AQUA generates far fewer fines during backwashing and transport than competitor products. This translates directly to less material loss, reduced filter bed fouling, and a longer overall service life for your media.

Certified Purity: FM AQUA is produced under strict quality controls to ensure minimal ash content and to meet NSF/ANSI standards, guaranteeing it will not introduce unwanted impurities into the water stream.
