pH Optima

pH Optima is a high purity calcium carbonate lime produced for dependable pH correction, buffering and neutralisation in a wide range of industrial applications. It is developed to deliver rapid and accurate pH adjustment in demanding environments such as effluent treatment plants, acid gas scrubbers and sludge conditioning systems. Its refined composition with calcium carbonate levels of not less than ninety five per cent gives a clean and predictable reaction profile that supports consistent performance across both continuous and batch operations.

Benefits

pH Optima provides a combination of purity, consistency and operational convenience that improves the reliability of industrial treatment systems.

  • High purity ensures reliable pH control
  • Consistent reactivity reduces dosing variation
  • Helps precipitate metals and neutralise acids
  • Supports compliance with discharge standards
  • Improves sludge dewatering and handling
  • Compatible with automated dosing systems

Overall, users gain a stable and predictable treatment solution that supports efficient plant operation.

Uses

pH Optima is used across environmental and water treatment operations where accurate pH modification is essential.

  • pH correction in effluent treatment plants
  • Acid neutralisation in gas scrubbers
  • Conditioning of sludge for improved handling
  • Application across environmental and water treatment sectors

In essence, pH Optima serves as a dependable agent for pH stability in systems that demand consistent and repeatable results.

Production

The product is produced in different kiln configurations to meet varied industrial needs. Standard PFR kilns supply material in the fifty to one hundred millimetre range while rotary kiln options provide ten to thirty millimetre material. Traditional kilns offer sizes above one hundred millimetres. Custom grading is available between ten and one hundred millimetres to allow the product to be matched precisely to user requirements.
