Their effectiveness in a wide pH range and compatibility with high-volume treatment operations make them the preferred choice for large-scale processes.
Despite the growing interest in bio-based and organic alternatives, the established performance of inorganic coagulants ensures their continued dominance in primary treatment stages. Suppliers are focusing on developing low-sludge, high-efficiency formulations to reduce operational costs and environmental impact.
Environmental Regulations and Concerns Over Chemical-Based Water Treatment
The flocculant and coagulant market faces growing regulatory scrutiny due to the potential environmental impact of synthetic chemical agents. Some coagulants, such as aluminium and metal salts, can result in sludge production, a change in the acidity of the water, and environmental harm.
Governments across the globe are tightening the regulations on the use of hazardous coagulants in their countries, where industries are looking for sustainable alternatives. Tight regulations such as the Safe Drinking Water Act (SDWA) in the USA and EU Water Framework Directive, along with strict industrial wastewater discharge standards, are enforcing limits on toxic chemical effluent, further fuelling demand for biodegradable and non-toxic alternatives.
Moreover, coagulation sludge generates disposal costs for municipal and industrial clients are not finding easy to overcome as treatment plants will add equipment to handle the sludge and dewater it. Focusing towards the heavy metal content in a coagulant raises questions of long-term contamination potential for both aquatic environments and groundwater stores.
This leads to focusing on the research for alternatives in formulations to less sludge generation and more efficient water treatment without harming the environmental safety.
Emergence of Green and Bio-Based Coagulation Technologies
Rise of plant-based polymeric flocculants and natural coagulants to protect the environment globally. Water treatment industries are ever-searching for solutions that are non-toxic, which is eco-friendly alternatives including chitosan-based and starch-derived flocculants are gaining traction.
