PolyAluminium Chloride (PAC)

The effective technology for water purification: PolyAluminium Chloride (PAC)
PolyAluminium Chloride (PAC)

Description

PolyAluminium Chloride production is one of the most exigent process for glass-lined equipement due to its high corrosive and abrasive effect.

That's why, the experience and the qualification of De Dietrich Process Systems allow to meet qualitatively those process requirements.

Over 30 years, we have ever supplied hundreds of glass-lined reactors running for PAC production, which represent the heart and the main critical point of the PAC process. Through this great experience, we have acquired deep knowledge and compétences concerning the PAC process requirements and its characteristics.

The PAC  synthesis occurs under high pressure and high temperature. PolyAluminium Chloride is the product of the batch reaction between solid Aluminium Hydroxide (AL(OH)3) and liquid Hydrochloric acid (HCI).

The De Dietrich Process Systems enamel is completely dedicated to the highly corrosive and abrasive process and we have also developped specific solutions for the PAC reactor:

  • De Dietrich enamel 3009 HA - Visual signal with a great resistance against acid environment (HCI)
  • Visual detection of the corrosion through different colors of enamel layers
  • Adapted Impeller agitator with a special geometry

De Dietrich Process Systems solutions for PAC Process:

  • Dedicated reactor
