Return on Investment (ROI)
Proven economic and operational benefits
Operational Cost Reduction
Savings on chemical products (coagulants, flocculants) and lower sludge generation compared to conventional treatments
Extended Operation Cycles
Longer intervals between regenerations due to high purity (80-100% clinoptilolite), reducing downtime and brine costs
Removal Efficiency
Ammonia removal proven by independent column adsorption studies (Tosun, 2012)
Regulatory Compliance
Guaranteed compliance with applicable discharge limits and potability standards under local regulations
Applications in Water Treatment
Solutions for different treatment systems
Industrial Effluent Treatment
Removal of ammonia (NH₃/NH₄⁺) from effluents of chemical, petrochemical, textile and food industries. High-purity clinoptilolite (80-100%) adsorbs ammonium by cation exchange with efficiency exceeding 95% in column adsorption (fixed bed) — the typical configuration for continuous effluents; in batch mode removal is lower. Reduces chemical costs and meets applicable discharge limits (NH₃ less than 20 mg/L under local regulations).
Municipal Water Treatment
Final polishing in water treatment plants for removal of ammonia, heavy metals (Pb, Cd, Hg) and residual turbidity. The high CEC (150-190 meq/100g) enables operation cycles 30-50% longer than low-purity zeolites, reducing regeneration frequency.
Heavy Metal Removal
Selective adsorption of Pb²⁺, Cd²⁺, Hg²⁺, Cr³⁺, Ni²⁺ and Zn²⁺ from contaminated water. Studies demonstrate adsorption capacity of 15-40 mg/g for Pb²⁺ (Velarde et al., 2023). Applicable in groundwater remediation, landfill leachates and mining effluents.
Removal of Cs⁺ and Sr²⁺ Ions
Selective adsorption of cesium (Cs⁺) and strontium (Sr²⁺) ions from aqueous solutions by cation exchange. Natural clinoptilolite has high affinity for these cations: studies report removal of ~99% Cs⁺ and ~92% Sr²⁺ (Senila et al., 2023). Applicable in batch or column effluent treatment containing these ions.
