Description
According to a research report published by Transpire Insight, the algae treatment chemical market size is projected to grow from USD 3.87 billion in 2026 to USD 5.47 billion by 2035, at a CAGR of 5.03% during the forecast period 2027-2035. The market grows due to the increasing need for water purification in municipal wastewater, the growth of aquaculture facilities, the deterioration of harmful algal blooms because of climate change, and strict regulations for municipal wastewater treatment.
Introduction
As industries, municipalities, and agricultural sectors turn to more efficient ways to control biofouling and HABs, the Algae Treatment Chemical Market is rapidly expanding. Enhanced nutrient pollution in water bodies due to increasing urbanization and industrialization has led to the need for specific chemical treatment. As regulations increasingly focus on environmental safety, today's treatment chemistry is rapidly moving toward eco-friendly, biodegradable, and non-toxic algaecides to help maintain aquatic environments in a healthy and safe manner and to provide clean water for the world.
Recent Development News
January 2026: Solvay introduced a new line of eco-friendly, peroxide-based oxidizers designed for use in large freshwater reservoirs to remove toxic algal blooms without the generation of hazardous chemical residues in water for drinking purposes.
May 2026: BASF SE partnered with advanced water technology organizations to apply chelated copper and quaternary ammonium products that are formulated specifically for industrial cooling towers and commercial aquaculture ponds.

Regional Growth and Demand Analysis by Transpire Insight
North America's market is the biggest market, as its water quality rules are among the strictest in the world. The EPA-imposed U.S. Clean Water Act places treatment obligations on treatment facilities and industrial operators, leaving municipal utilities, recreation officials, and lake managers on constant treatment plans. Suppliers have responded by providing new products. SePRO's SeClear is an EPA-registered algaecide that also complexes phosphorus, the nutrient that can cause future blooms. The company also provides AI-driven satellite monitoring, providing continuous insights into waterbody health.
Pollution regulation, industrial water requirements, and urban infrastructure development are growing in tandem, driving the highest growth in Asia Pacific. There is increasing usage of algaecides in aquaculture and surface water treatment, and with increasing public health awareness, commercial aquatic centres are adding to the demand for algaecides. Consumers are also increasingly choosing brands that offer milder chemistries such as peroxide-based, copper-free granular algaecides certified for use in drinking water by SePRO. Regional operators are continually being driven towards sustainable and effective industrial wastewater treatment solutions.
Top 15 Trends in the Algae Treatment Chemical Market
Warmer temperatures and nutrient runoff are intensifying harmful algal blooms, pushing utilities, lake managers, and aquaculture operators toward more frequent, proactive algaecide applications across regions.
Operators favor peroxide-based, copper-free algaecides because they oxidize algae and cyanotoxins while avoiding copper accumulation in sediments, making them suitable for sensitive drinking water reservoirs.
Products like SeClear combine algae control with phosphorus binding, addressing the nutrient driving regrowth, lengthening treatment intervals, and reducing follow-up applications needed by lake managers.
Satellite imagery and AI models deliver continuous insight into waterbody health, helping operators detect blooms early and schedule targeted treatments before algae reach nuisance levels.
Tightening water quality and nutrient-pollution rules, including the U.S. Clean Water Act, require treatment facilities and industrial operators to control algal growth, sustaining demand.
Desalination plants in water-scarce regions need algae pre-treatment to prevent biofouling, protect costly membrane filters, and create new demand for specialized algae-treatment chemical solutions.
