Reliable access to safe water depends on effective treatment processes and a secure supply of critical chemicals. Through its Water Care business, Protea Chemicals combines local manufacturing, technical expertise and regional reach to support water treatment operations across South Africa and the broader African continent.

As a member of the Omnia Group, Protea Chemicals has a long history of supplying speciality chemicals across multiple industries. In recent years, the company has undergone a strategic restructuring to improve efficiency and prepare for future growth. This included bringing certain businesses into the broader Omnia Group to benefit from shared manufacturing, logistics and technical resources, while strengthening Protea Chemicals’ ability to serve its key markets and expand its specialised offerings.

This process positioned Protea Chemicals Water Care as a distinct and strategically important operation within Omnia’s Chemicals segment.

“Water treatment is an essential service that supports municipalities, mining operations and industrial customers, and we see significant opportunities to expand our contribution to water security across the continent. Protea Chemicals is a strong and profitable business, and we are focused on supporting its continued growth in the years ahead,” says Joyce Jabane Bauwens, general manager, Protea Chemicals Water Care.

Moving beyond product supply

Historically, water treatment chemicals have often been viewed as commodities. Protea Chemicals believes this approach overlooks the complexity of modern water treatment and the critical role chemistry plays in achieving treatment objectives.

“The chemicals are one part of the solution. We believe in providing the expertise, technical support and security of supply needed to ensure safe, reliable and compliant water services,” says Bauwens.

Effective treatment depends on selecting the correct chemistry for each application, optimising dosing programmes, monitoring system performance and ensuring compliance with increasingly stringent regulatory requirements.

Strengthening local manufacturing

A key differentiator for Protea Chemicals is its investment in local manufacturing capacity. The company manufactures its Zetafloc coagulant range at its Mobeni facility in Durban and ferric sulphate at its Blackheath facility in Cape Town. Both products play a vital role in water treatment processes. In addition, Protea Chemicals operates a chlorine packaging facility in Sasolburg.

This local manufacturing footprint provides customers with greater security of supply, reduced reliance on imported products and shorter lead times. It also allows Protea Chemicals to maintain close oversight of product quality, respond more rapidly to changes in customer demand and provide technical support backed by local production capabilities. In an environment where global supply chains remain vulnerable to disruption, local manufacturing helps ensure the consistent availability of critical water treatment chemicals.

“Local manufacturing has become increasingly important in an environment where global supply chains remain vulnerable to disruption, largely driven by geopolitical tensions. By producing critical treatment chemicals locally, Protea Chemicals helps reduce its reliance on imports, which ensure security of supply for customers,” states Bauwens.

According to Bauwens, the benefits extend beyond operational resilience. “Local production also supports economic development in a key sector through employment creation, skills development and investment in South African manufacturing capabilities.”

Serving a diverse customer base that spans municipalities, industrial facilities and mining operations, Protea Chemicals supplies chlorine and serves customers in every province in South Africa. The company also exports to regional markets including Angola, Namibia, and Zambia, while maintaining a broader footprint across East and West Africa. This extensive reach underscores the scale of its operations and its significant role in supporting water treatment and industrial processes across the continent.

Supporting water security

Chlorine remains one of the most important chemicals used in drinking water treatment, providing the final barrier against waterborne disease. “Protea Chemicals plays a significant role in ensuring reliable chlorine supply through its packaging facility and national distribution network,” says Bauwens.

However, the company believes supply alone is not enough. Demand forecasting, logistics planning and technical support are equally important in helping municipalities maintain treatment performance and comply with water quality regulations.

This is particularly relevant as programmes such as Blue Drop Certification continue to place greater emphasis on performance accountability and compliance within municipal water systems. Across the region, customers are increasingly looking beyond upfront chemical costs and focusing instead on total treatment cost, performance and lifecycle value.
Bauwens cautions that selecting treatment chemicals based purely on price can result in poor treatment outcomes, equipment damage, compliance failures and ultimately higher costs.

“Water treatment is not about purchasing the cheapest chemical. It is about selecting the right chemistry for the application and ensuring it is applied correctly to achieve reliable, compliant and cost-effective treatment.”

Growing opportunities across Africa

The company sees significant opportunities for African-manufactured water treatment solutions as countries increasingly prioritise localisation, infrastructure development and supply chain resilience.

“At the same time, success in African markets requires solutions tailored to local conditions. Water quality characteristics, infrastructure maturity, technical skills availability and financial constraints vary significantly across the continent. Our regional footprint and technical expertise position us well to develop fit-for-purpose solutions that address these realities while delivering sustainable treatment outcomes,” explains Bauwens.

Despite the challenges facing the sector, Protea Chemicals remains optimistic. “As part of the Omnia Group, Protea Chemicals benefits from the scale, resources and expertise of a business with more than 70 years of experience across the mining, agriculture and chemicals sectors. This gives customers confidence in our ability to provide a reliable supply of products, backed by technical support and practical industry knowledge,” she adds.

Bauwens believes that the greatest opportunities are expected to come from municipal water treatment, industrial water optimisation, and water reuse and recycling initiatives as water scarcity and environmental pressures continue to intensify.

“Reliability of supply, treatment performance and operational efficiency are becoming increasingly important considerations. At the same time, growing water scarcity is driving greater interest in water reuse, with municipalities and industries increasingly viewing wastewater as a resource rather than a waste stream. As investment in sustainable water management increases, demand for practical, fit-for-purpose treatment solutions is expected to continue growing across Africa.”

Investing in water treatment and effective chemical management is not an optional expense; it is essential for protecting public health, maintaining regulatory compliance and ensuring the long-term reliability of water and wastewater services.

“The chemicals are one part of the solution. We believe in providing the expertise, technical support and security of supply needed to ensure safe, reliable and compliant water services.”
