  • How are alum and ferric chloride used in water treatment?
  • As every water treater knows, coagulants are used in the first step of water treatment; they destabilize the water so micro flocks can begin to form. This is followed up by a polymer, which turns it into a larger flock by creating a bigger charge.
  • Should aluminium coagulant be used in water treatment?
  • However, the use of aluminium-based coagulant has become under scrutiny. Besides the large amount of sludge produced, high level of aluminium remaining in the treated water has raised concern on public health.
  • What is a good substitute for alum & ferric chloride?
  • Proprietary products, instead of commodities, may offer a better solution. For example, a few products from ATS Innova’s ATS 800 line are excellent substitutes for alum and ferric chloride: ATS 835 is a great replacement for alum because it does an amazing job, but with a much, much smaller dose.
  • What are alum and ferric chloride?
  • Alum and ferric chloride are two widely-used “commodity chemical” coagulants that have been around for a long time. Why are alum and ferric chloride so commonly used?
  • Some water treaters simply aren’t aware of alternative products.
