ULTRASTERIL®
a high-tech alternative to chlorine and hypochlorite for water disinfection
WATER WITHOUT RISK
Today, the use of chlorine and hypochlorite for water disinfection remains common due to their long-lasting residual effect.
However, modern environmental standards, stricter regulations, and economic pressures require the adoption of safer technologies—solutions that minimize chemical risks, remain effective against microbiological threats, and reduce operating costs as well as dependence on transporting hazardous reagents.
ULTRASTERIL®
is a system that generates a concentrated oxidant mixture (at least 1 g/L in terms of active chlorine) for efficient and eco-friendly on-site water disinfection.
INNOVATION IN WATER DISINFECTION
High Efficiency
Elimination of pathogens with no risk of resistance
Long-lasting residual effect
