Water is the intrinsically linked cord of the process industries – from food & beverage to energy and mining to manufacturing. It’s an important part of manufacturing and production processes that demand innovation in both sustainability and efficiency.

Environmental companies within the UK and throughout the world are looking to boost productivity while also meeting stricter regulations and environmental sustainability goals. 

For plant managers and sustainability officers, keeping up with the newest industrial water treatment technologies can seem complicated. However, understanding innovation in sustainable water treatment technologies for the process industries is essential for water recycling efforts, long terms cost savings and the promotion of sustainable wastewater management.

I. Overview: Why Innovation Matters in Water Treatment

In sectors such as food & beverage, energy, mining and manufacturing there are several applications in which water is used. These processes include, production, washing, boiler feed and cooling towers among other uses. However, these same industries often face notable challenges ranging from microbial contamination and high mineral content to the presence of trace heavy metals and organic compounds.

Efficient and effective water treatment is an important factor in mitigating environmental issues, safeguarding product quality and supporting sustainable production processes.

II. Unique Challenges Across Sectors

Each industry sector has its own water treatment challenges to deal with:

• Food & Beverage: Requires high-quality water meeting stringent quality standards for the production of its products.
• Energy: Demands reliable boiler feed and cooling water treatment as well as effective wastewater recycling dealing with varying water quality parameters. 
• Mining: Must address high mineral loads, heavy metal contamination and suspended solids concentrations.
• Other Process Industries: Often face diverse water contaminant profiles and fluctuating process volumes that require specific treatment solutions to address particular contaminants.

Understanding these issues is the first step toward analysing and adopting innovative treatment technologies that can meet both regulatory requirements and company sustainability goals.

There has been several improvements to biological treatment processes recently – the membrane bioreactor market reached US$3.44 bn in 2018 . These improvements include enhanced bioreactors with impregnated flexible media and microbial fuel cells that use specific bacteria to generate electrical power. Furthermore, breakthroughs in biofilm management are being bolstered by unique microbubble and nano bubble aeration technology.

These technologies utilise micro and nanometer size bubbles to dramatically increase oxygen transfer rates, enhancing microbial treatment activity and thus improving overall treatment efficiency.

The result of integrating these unique technologies is a more robust biological process that not only treats water more effectively but also can harness energy from waste streams if appropriate.

D. Adsorption Technologies & Sustainable Bio Polymers

Adsorption is an important way for removing water contaminants. There has been ongoing improvements in several areas:

• Activated Carbon Enhancements
