1. Technical Origin The FOF project research originated from the research achievements of the French National Center for Scientific Research (CNRS), which is the largest basic research institution in Europe and also the birthplace of the project. Over the past 40 years, scientists from the Scale and Corrosion Research Laboratory have innovatively invented a new material capable of completely preventing scale formation and delaying the corrosion of various metals. They named this new material FOF. Since 2005, with the assistance of the FOF research team, our company has conducted research for seven years and successfully synthesized the first FOF product in the world, which has been successfully applied to various water fields. The successful synthesis and mass production of FOF have injected new blood into the global water treatment industry, marking the arrival of the era of scale-free water systems.

2. Introduction to the Technical Principle of FOF. The formation of scale crystals is divided into two stages: nucleation and crystal lattice formation, encompassing six processes in total, namely the formation, growth, and maturation of nucleation, and the formation, growth, and maturation of the crystal lattice. Traditional scale inhibition technologies or products focus on interfering with the growth and maturation of the crystal lattice during the second stage (i.e., the crystal lattice formation process) through dispersion, dissolution, and other methods. In contrast, FOF technology intervenes in the form of ions from the initial stage of nucleation, preventing various scaling factors from combining with carbonate and hydroxide ions, thereby completely eliminating the formation of insoluble salts and nipping scale in the bud. The scale inhibition rate can reach over 99.5%. Thanks to its leading mechanism of action, FOF technology exhibits significant scale inhibition effects on water with high hardness and high alkalinity, and also possesses the following advantages: (1) ultra-low phosphorus content, effectively promoting environmental protection. (2) scale inhibition effect reaching over 99.5%, basically achieving scale-free conditions. (3) effectively improving metal corrosion conditions. (4) capable of achieving high-temperature scale inhibition, with stable physicochemical properties of the product (currently tested at water temperatures up to 200℃).

3. FOF-Faou Water Quality Treatment Technical Services Our services originate from and are loyal to our customers, and are based on them. (1) During the early stage of system water quality analysis, we will conduct on-site inspections at the customer's location and collect water samples for testing and analysis to understand the operating status of the system. Water sample analysis includes system operating water quality analysis, makeup water quality analysis, softened water quality analysis, scaling rate and corrosion rate analysis, and a water quality testing report will be issued; (2) Selection and design of FOF water quality treatment agents Based on the system type, usage conditions, and water quality testing results, we select the appropriate FOF water quality treatment agent for the system, and then conduct tests using makeup water and system water to ensure optimal agent selection and usage. The tests include: GB/T 16632-2008 Determination of Scale Inhibition Performance of Water Treatment Agents - Calcium Carbonate Deposition Method GB/T 18175-2014 Determination of Corrosion Inhibition Performance of Water Treatment Agents - Rotating Coupon Method
