Applications
Swimming Pool Water Treatment with Ozone Technology
Traditional chlorine treatment leaves odor, irritation, and harmful by-products. Ozone provides a cleaner, safer alternative for pool water.
Our ozone systems for swimming pools ensure crystal-clear water, free from chloramines and pathogens. Unlike chlorine, ozone destroys bacteria, viruses, and resistant microorganisms without leaving harmful residues. The result is sparkling, odor-free water that enhances swimmer comfort and meets global health standards. From residential pools to municipal aquatic centers, our systems reduce operating costs while ensuring sustainability.

Why Governments and Industries Prefer Ozone?
Governments, municipalities, and public health institutions as well as many industries are increasingly adopting ozone technology as a safer, more sustainable alternative to traditional chemical treatments.
Chlorine-Free & Safer for Public Use
Ozone eliminates pathogens and contaminants without leaving behind chlorine by-products or chemical residues. This means healthier drinking water, safer swimming pools, and cleaner air for public spaces.
Eco-Friendly & Sustainable
As a natural oxidant, ozone reverts to oxygen after use, leaving no harmful impact on the environment. This makes it a sustainable choice for large-scale municipal projects and public institutions.
Cost-Effective in the Long Run
By reducing chemical purchases, storage, and handling, ozone significantly lowers operating costs. It also minimizes corrosion and extends the lifespan of equipment in public facilities like water plants and hospitals.
CPCB & WHO Compliant
Our systems are designed to meet or exceed Central Pollution Control Board (CPCB) and World Health Organization (WHO) guidelines, ensuring compliance with national and international regulatory frameworks.
Croissance has been a trusted partner for government hospitals, municipal corporations, and institutional clients across India, delivering solutions that combine safety, sustainability, and cost-efficiency.
