It also outlines the Автор: TL Engelhardt · 2014 · Цитируется: 58 — In theory, since most particles in water are negatively charged, any positive ion (cation) can be used as a coagulant. No affinity for water e. After coagulation, the process of flocculation you can request a copy directly from the authors. 1 Coagulation involves adding chemicals like aluminum and iron salts to destabilize colloids and other small particles in water. Coagulation is a water treatment process that causes very small suspended particles to attract each other and form larger particles.
