Revolucionando o tratamento municipal de água: A potencial mudança do Brasil para a tecnologia de dióxido de cloro.

In the bustling urban landscape of Brazil, municipal water utilities produce potable water through numerous water treatment plants (WTPs), some mega plants supply a staggering 2 billion litres of water daily.
However, the relentless march of population growth has encapsulated these facilities within dense urban environments, complicating their operations significantly.

The triple threat of water pollution, increasing populations, and climate change have exacerbated the contamination of water supplies, presenting a formidable challenge to maintaining water purity.

Traditionally, the use of Chlorine Gas (Cl) for disinfection, despite its efficacy, has posed significant risks due to the necessity of transporting and handling this hazardous material through populated areas. The limitations of chlorine technology have rendered the achievement of World Health Organisation (WHO) water quality targets an elusive goal. Addressing these multifaceted issues, Scotmas has emerged with a pioneering solution through its Chlorine Dioxide (ClO2) technology, offering a beacon of hope.

This innovative approach promises a tenfold reduction in the chemical quantities required for water treatment and heralds significant operational cost savings. More importantly, it ensures the delivery of highly effective and compliant water disinfection, simultaneously eliminating the unsafe transportation of chlorine gas across populated zones.

The Advent of Chlorine Dioxide Technology

For water utility conglomerates in Brazil, the transition to Scotmas’ Chlorine Dioxide technology is not merely a change in chemical usage but a comprehensive overhaul involving advanced dosing equipment, profound application expertise, and a wealth of experience. This holistic package empowers water utilities to seamlessly transition towards a more efficient, safer, and environmentally friendly disinfection process.

The Mechanism Behind the Innovation

The core of this revolutionary technology lies in the synthesis of Chlorine Dioxide through the mixing of two precursor chemicals, sodium chlorite (NaClO2) and hydrochloric acid (HCl), to produce an aqueous ClO2 solution. Remarkably, this process eschews the need for auxiliary utility inputs, relying solely on dilution water and electricity to power the essential components such as pumps, instruments, and control panels.

The Multifaceted Benefits of Chlorine Dioxide

Chlorine Dioxide stands as a formidable replacement for Chlorine Gas in pre-oxidation and disinfection. Its precursor chemicals are markedly less hazardous, mitigating the risks associated with transportation and usage.

Unlike Chlorine, ClO2 does not partake in chlorination, nor does it yield chlorination by-products (CBPs) like trihalomethanes (THMs) and haloacetic acids (HAAs), which pose significant health hazards.

The efficiency of ClO2 means that less of it is required to achieve the same level of disinfection as chlorine, underscoring its economic and environmental advantages.

A Recognised Advantage

The United States Environmental Protection Agency (USEPA) has recognised ClO2‘s superior efficacy against a broad spectrum of pathogens, including bacteria, viruses, and protozoa, outperforming traditional chlorination technologies. This endorsement highlights ClO2‘s effectiveness and reinforces its potential to set new benchmarks in water treatment standards.

Chlorine Dioxide – The Way Ahead

The adoption of Scotmas’ ClO2 technology by Brazil would represent a monumental leap forward in water treatment, promising a future where clean, safe, and sustainable water is accessible to all, even in the face of urban expansion and environmental challenges.

This potential transition exemplifies innovation and sets a precedent for water utilities worldwide, heralding a new public health and environmental stewardship era.
