The global Algae Online Monitoring System market size is predicted to grow from US$ 182 million in 2025 to US$ 314 million in 2032; it is expected to grow at a CAGR of 8.3% from 2026 to 2032.

The online algae monitoring system is a comprehensive solution that involves deploying multi-point monitoring equipment (online algae monitor + multi-parameter water quality sensor) at key sections or water areas. Through fixed stations, buoys, or integrated shore-side cabinets, it continuously collects, automatically transmits, and centrally analyzes algae indicators such as chlorophyll-a and phycocyanin, as well as water quality data such as temperature, turbidity, dissolved oxygen, and pH. The system typically consists of field sensor terminals, power supply and communication modules (mains power/solar power + 4G/5G/BeiDou/wired), data acquisition and edge computing units, a cloud platform, and a large visualization screen. It enables real-time display of algae concentration curves, early warning of exceeding standards, algae bloom risk assessment, and coordinated control with water plant processes, dam scheduling, and aeration/chemical dosing systems. It is one of the core infrastructures for water source protection, lake and river management, refined aquaculture management, and environmental regulatory departments early detection, early warning, and early response efforts. In 2025, sales volume was 410,000 units, with an average price of $425, total production capacity of 500,000 units, and a gross profit margin of 35%.

From the demand side, online algae monitoring has upgraded from buying a few instruments to building a system. The driving force behind this is no longer just checking algae concentration, but rather overall risk control centered around water safety and aquatic ecosystems. On one hand, there are drinking water sources, reservoirs, regulating lakes, and South-to-North Water Diversion/inter-basin projects. Algal blooms are directly linked to odor complaints, water outages, and emergency chemical treatment costs. Water utilities and river basin management agencies are no longer satisfied with manual sampling + weekly/monthly reports, but hope to support scheduling and process coordination through multi-point monitoring stations + online data + risk indices. On the other hand, there are lake water environment management, aquatic ecological restoration demonstration projects, and high-value aquaculture water bodies. Under the long-term pressure of policies such as the River Chief System, Lake Chief System, Water Ten Measures, and Black and Odorous Water Body Treatment, algal changes are regarded as leading indicators of eutrophication and cyanobacterial bloom risks. In the feasibility studies and performance evaluations of many projects, whether an online algal monitoring system is included has been written as a mandatory clause or a deduction item. Overall, online algal monitoring systems are no longer accessories in scientific research projects, but rather one of the basic configurations in water source safety, water environment performance evaluation, and smart water/smart fisheries projects. From a supply and business model perspective, competition in this sector has clearly shifted from selling sensors and standalone devices to selling systems, services, and closed-loop capabilities. Individual equipment manufacturers that only offer a few probes and a set of software are easily caught in price wars during bidding processes. Conversely, manufacturers that can package algae monitoring + multi-parameter water quality + meteorological/hydrological data + platform algorithms into watershed water environment monitoring platforms, smart water management platforms, and smart fishery cloud platforms have a better chance of winning overall projects for a watershed, an entire lake area, or a group of aquaculture bases. More importantly, homeowners are no longer satisfied with just curves and alarms, ??but are asking: Can this system guide me on when to increase oxygen in advance, when to reduce load or shut off water in advance, and when to conduct emergency water storage?Whoever can truly embed algae data into scheduling rules, model predictions, and operation and maintenance SOPs, proving that they can help reduce the number of algal blooms, the number of emergency medications needed, and the number of water outages and fish deaths, will be able to charge long-term fees based on system construction + annual operation and maintenance services + data services, turning what was originally a one-time project revenue into a sustainable digital operation business for the water environment over 5-10 years.
