Frequently asked questions
Water Treatment questions and answers.
1. What is the role of Sulphur Dioxide (SO₂) in water treatment? Answer:
Sulphur Dioxide (SO₂) is primarily used for dechlorination—the process of removing residual chlorine from treated wastewater before it’s discharged into the environment. This helps meet environmental compliance standards and protects aquatic ecosystems from harmful chlorine exposure.
2. Why should I use Carbon Dioxide (CO₂) instead of traditional acids for pH control?
CO₂ offers a safer, more precise, and eco-friendly way to control pH compared to traditional acids like sulphuric or hydrochloric acid. It reduces the risk of chemical burns, minimises corrosion in equipment, and contributes to a lower carbon footprint when sourced sustainably. Visit our CO2 page to find out more.
3. What is Ammonia (NH₃) used for in water treatment?
Ammonia is used in chloramination, where it reacts with chlorine to form chloramines—a stable disinfectant that provides long-lasting protection in water distribution systems. It’s especially valuable for municipal water supplies and large industrial cooling systems.
4. Is CO₂ safe to handle?
Yes, CO₂ is much safer to handle than strong acids. It doesn’t produce harmful fumes, reduces the risk of chemical spills, and eliminates the danger of acid burns. However, proper ventilation is essential in confined spaces to prevent CO₂ buildup.
5. How does SO₂ improve wastewater treatment efficiency?
SO₂ reacts quickly with chlorine, making the dechlorination process faster and more efficient than traditional methods. It also requires smaller dosages, reducing chemical costs and minimising the impact on downstream processes.
6. Does using CO₂ reduce operational costs?
Yes, using CO₂ can lead to significant cost savings by:
- Reducing equipment corrosion (lower maintenance costs)
- Improving pH control efficiency (less chemical wastage)
- Enhancing process stability (reduced downtime)
In some case studies, companies have reported cost reductions of up to 35% after switching to CO₂.
7. Is Ammonia safe to use in water treatment?
Ammonia is safe when handled correctly and in controlled environments. It’s commonly used in the water industry and poses minimal risk when proper storage, handling, and safety protocols are followed.
8. How does using Ammonia improve water disinfection?
Ammonia helps create chloramines, which:
- Provide longer-lasting disinfection than chlorine alone
- Reduce the formation of harmful disinfection by-products (like trihalomethanes)
- Improve taste and odour in drinking water
This makes ammonia an excellent choice for municipal water supplies and long distribution networks.
9. Do you offer bulk supply options for CO₂, SO₂, and Ammonia?
Yes, we offer flexible supply options tailored to your needs, including bulk deliveries for large-scale operations and smaller quantities for specialised applications. Our robust logistics network ensures consistent, on-time supply across the UK.
10. How do I know which water treatment chemical is right for my business?
Choosing the right chemical depends on your specific process requirements, including water composition, treatment goals, and regulatory compliance needs. Our expert team will work with you to assess your system and recommend the most efficient, cost-effective, and sustainable solution.
