Flokkulointikemikaalit, or flocculants, are chemical agents used in water treatment processes to facilitate the aggregation of suspended particles into larger clumps called flocs. These flocs are then more easily removed from the water through sedimentation or filtration. This process is crucial for clarifying water by removing turbidity, color, and other suspended impurities.

Commonly used flocculants include inorganic salts like aluminum sulfate (alum) and ferric chloride, as well as various organic polymers. Inorganic flocculants work by neutralizing the negative charges on suspended particles, allowing them to come together. Organic polymers, on the other hand, often bridge between particles, physically binding them into larger flocs. The selection of a specific flocculant depends on factors such as the water's pH, temperature, and the nature of the suspended solids.

The application of flocculants is a vital step in many water and wastewater treatment facilities, including municipal water purification plants, industrial process water treatment, and sewage treatment. By effectively aggregating fine particles, flocculants significantly improve the efficiency of subsequent solid-liquid separation processes, leading to cleaner and safer water. The dosage and type of flocculant must be carefully controlled to optimize performance and minimize chemical costs.
