Calcium Nitrate 32 Percent Solution
calcium and nitrate ions and is designed for industrial, water-treatment, wastewater-treatment and process applications requiring a convenient liquid source of calcium nitrate.
Application & Uses
Applications & Uses
Calcium Nitrate 32% Solution is particularly useful in wastewater and sewage treatment, where nitrate can be used in appropriate treatment programs to help control anaerobic conditions and associated hydrogen sulphide (H₂S) generation and odour problems.
It may also be used for:
- Industrial wastewater treatment
- Sewage and effluent-treatment systems
- H₂S and odour-control treatment programs
- Process-water applications
- Calcium supplementation in suitable industrial processes
- Concrete and construction chemical formulations, subject to formulation requirements
- Chemical manufacturing
- Specialty water-treatment formulations
- Industrial nitrate and calcium source
Wastewater & H₂S Control
In wastewater systems, prolonged anaerobic conditions can encourage sulfate-reducing bacteria to generate hydrogen sulphide. Calcium nitrate solution can be dosed as part of a properly designed nitrate-treatment program to help maintain conditions that suppress sulfide formation.
Typical applications include sewer networks, wastewater collection systems, pumping stations, holding systems and industrial effluent systems.
Dosage & Directions for Use
Dosage should be determined from wastewater characteristics, retention time, sulfide loading, temperature and the desired treatment objective rather than using a universal fixed dosage.

Product Description & Chemical Profile
Calcium Nitrate 32% Solution
Product Description
Calcium Nitrate 32% Solution is a clear, water-soluble liquid containing approximately 32% w/w calcium nitrate [Ca(NO₃)₂]. It provides readily available calcium and nitrate ions and is designed for industrial, water-treatment, wastewater-treatment and process applications requiring a convenient liquid source of calcium nitrate.
The liquid form provides advantages over solid calcium nitrate where accurate dosing, continuous injection, rapid mixing and automated chemical-feed systems are required.
