Process water
Neutralization and pH control.
Calcium carbonate for neutralizing acidic water and process streams, from fertilizer and mineral processing to municipal treatment. Match the material to your chemistry, contact time and process.
Control starts with the material. Municipal and industrial water-treatment operations use calcium carbonate for pH adjustment, buffering and selected treatment processes.
Match the grade to your system chemistry, contact time and target conditions.
Particle size affects the surface area available for reaction. Treatment conditions determine dissolution and performance; our team can help you compare grades and obtain samples for plant trials.
Quality & analysis
Analysis for incoming-material control. Request the current calcium-content and heavy-metal analysis to evaluate the material against your process and discharge requirements.
Certificate of analysisWith every load
- O1pH adjustment and buffering
- O2Particle sizing for your treatment system
- O3Analysis for incoming-material control
- O4Samples for process validation
Consistent sizing and documentation support purchasing, quality-control and compliance records. Calcium carbonate has also been studied for metal removal from contaminated water. Results from a particular research system do not establish performance in every plant; validate treatment efficiency in your own process.
Start with your specification. Bring the requirements of your operation. We’ll help you assemble the material information for a considered decision.
- O1System chemistry & contact timeShare incoming chemistry, target conditions and available contact time. These determine how the material should be evaluated.
- O2Material analysis & sizeRequest chemical and particle-size analysis for the grade under consideration, with measured results and reporting limits.
- O3Validation in your own plantEvaluate a sample under your treatment conditions before establishing a specification or operating dose.
The same stone, at work in four more places.
Fertilizer & mineral processing
Feed-phosphate production, acid purification and neutralization. The same grades serve manufacturing.
Livestock & feed
Calcium for dairy, beef, layer and breeder rations and mineral blends.
Crop nutrition
Lime for acidic soils, crop nutrition and seed coating.
Turf & landscape
Lime for turf soil pH, plus crushed landscape rock and decorative grades.
