According to a research report published by Spherical Insights and Consulting, the global algae treatment chemical market size was worth around USD 3.27 Billion in 2024 and is predicted to grow to around USD 5.81 Billion by 2035 with a compound annual growth rate (CAGR) of 5.36% from 2025 and 2035. The market for algae treatment chemical has a number of opportunities to grow due to environmental regulations, increasing water scarcity issues, and demand for cost-effective, green wastewater solutions.  

 

Market Overview

The global industry of algae treatment chemical encompassing substances used for controlling, removing, and preventing harmful algae blooms (HABs) in water bodies. Algae treatment chemicals (also called algaecides) are compounds designed to kill, control, or prevent the growth of algae in water bodies like pools, ponds, and industrial systems. Some of the common examples include copper sulfate, copper chelates, chlorine/shock, peroxides/hydrogen peroxide, chelating agents/flocculants, and organic acids. Rising pollution, stringent environmental regulations, and demand for safe drinking/industrial water are propelling the demand for algae treatment chemical.
