What it is
Limestone formulated for controlled, consistent neutralisation in effluent treatment systems, where pH stability directly governs precipitation behaviour, sludge conditioning, and discharge compliance.
What it does
- Maintains stable pH within the required operational envelope
- Governs precipitation behaviour for reliable heavy metal removal
- Supports effective sludge conditioning and downstream treatability
- Reduces chemical dosing variability across treatment cycles
- Ensures consistent discharge quality and compliance performance

What makes pH Optima the specified choice for effluent neutralisation compliance?
pH Optima's ≥95% CaCO₃ purity delivers the controlled neutralisation response that governs precipitation behaviour, sludge conditioning, and discharge quality — making regulatory compliance a process outcome, not a variable.
How does pH Optima reduce treatment risk across continuous and batch ETP systems?
Its engineered PSD eliminates dosing variability cycle to cycle — giving operators a stable pH envelope that protects heavy metal precipitation efficiency and downstream treatability, regardless of influent fluctuation.
Why is pH Optima the preferred calcium input where discharge standards are non-negotiable?
Because in environmental and water treatment, input precision defines output certainty. pH Optima's multi-grade sizing and ≥97% NV ensure consistent reactivity — translating directly into reliable, compliant discharge performance at every stage.
