The cause of blue-green algae
It is important to state that algae and BGA are not inherently harmful to water and wildlife. After all, they are naturally occurring phenomena. But certain conditions (including unnatural conditions caused by human activity) can cause excessive BGAs - what we call "blooming". It is these blooms that can affect the health of inland waters. Therefore, we can use blue-green algae sensors for online monitoring, which will allow you to better understand the specific conditions of water quality.
Algae are caused by a type of bacteria called cyanobacteria, which consist of single-celled species and others whose cells consist of colonies and filaments. These cyanobacteria thrive in warm, nutrient-rich water -- and if there are too many nutrients, harmful algal blooms can form. The most common causes of high nutrient levels are:
Wastewater (sewage, storm overflow)
Each of these pollutants contributes to the entry of large quantities of nitrogen and phosphorus into UK waters, whether by intentional dumping or otherwise. Then begins the process of eutrophication, where mats of algae starve other plants of wildlife and nutrients, and eventually, the plants decompose and produce carbon dioxide. In turn, the pH of the water decreases and it becomes essentially uninhabitable.
As we mentioned before, blue-green algae are easy to spot, and they often form a floating mat or scum on the surface of the water. They also make water appear paint-like, and water may appear green, teal, white, yellow, brown, red, or even purple.
But you might not always be able to spot BGAs on surfaces—sometimes they grow on rocks or the bottom of bodies of water. So you can get a pretty good guess at what's a BGA and what's not by looking at them (if they're visible), but monitoring equipment is needed to gauge the extent of the growth and its effect on the water.
Chlorophyll | Blue Green Algae-Water Quality Analyzer
The chlorophyll (blue-green algae) water quality analyzer uses the characteristic that chlorophyll (blue-green algae) has absorption peaks and emission peaks in the spectrum, and emits monochromatic light in the spectrum absorption peak of chlorophyll (blue-green algae) to irradiate the water , The chlorophyll (blue-green algae) in the water absorbs the energy of monochromatic light, and releases a monochromatic light with another wavelength emission peak.
The light intensity emitted by chlorophyll (blue-green algae) is proportional to the content of chlorophyll (blue-green algae) in the water. Proportional.The chlorophyll/blue-green algae water quality analyzer is widely used in sewage treatment plants, drinking water, aquaculture, chlorophyll detection, blue-green algae, industrial production and other fields.
Blue-green algae Analyzer Features:
（1）Automatic cleaning: effectively eliminate bubbles and dirt to reduce the influence of dirt on the measurement.
（2）Temperature compensation function: automatic temperature compensation, automatic calibration data with high accuracy and precision.
（3）Double-standard fixed thread: The prefabricated thread is more convenient to install and fix, and the double-standard prefab can meet the different needs of use.
（4）Automatically hang in the water: the product comes with a stainless steel plug that can hang in the water all the time, and the data is accurate. The product line core is made of high-precision copper, and the outer skin is flexible and resistant to bending, tensile and wear resistance. The longer the product line length, the deeper the depth in the water.
（5）Fluorescence detection: Use the fluorescence that reflects the characteristics of the substance, which can reflect the characteristics of the substance when the substance is in an excited state after being irradiated by ultraviolet light, to detect blue-green algae in the water. Detect blue-green algae when there are many algae in the water.
