Treating Blue-Green Algae Subscribe to our monthly newsletter to stay up to date with the latest news on algal blooms. Research over decades has shown that starving algae is one way to curb algae increases in lakes and this is done by carefully controlling the availability of nutrients on which algae depend to grow and increase. Here in Wisconsin, most of the state relies on groundwater, rather than surface water, for drinking water. Therefore, I assume the reason for control is a physical one rather than a nutritional reason. Must cover the entire surface of the lake.

Use phosphorus-free fertilizers and detergents to limit nutrient-rich runoff. A: Blue green algae, or cyanobacteria, can multiply quickly in lakes with high nutrient levels, particularly when the water is warm and the weather is calm. It is proven effective for green and blue-green algae. Some of the phytoplankton species are single cell algae which is about one tenth as thick as human hair and most scientists believe that they grow through the process of photosynthesis but there are some that are questioning that theory. The main categories of algae are blue-green, green, brown, and red. 4 Their toxins can affect cells, liver, and nervous systems. Algae can adapt during seasons within the same lake. It is generally more effective in deep reservoirs (mean depth >15 m). Effect of blue-green algae on humans and animals. The explanation of blue green algae used in this video sounds more like macro-algae (seaweed or moss). Water reservoirs often lack circulation, so the water is stagnant. Blooms are large colonies of algae that become visible without a microscope. Found inside – Page 108A wastewater treatment lagoon in Camden, South Carolina, used six microscreens to remove algae. ... If the microscreen openings were larger, water could be filtered at a faster rate, while still removing colonial blue-green algae. The microscopic visual difference is a thicker cell wall than Microcystis. This population explosion causes “blooms” of blue-green algae that turn the water green, often with floating layers of scum. Specific frequency programs must be used to ensure efficiency. People can suffer illnesses, paralysis and potentially liver cancer associated with algae contamination. 3 Blue-green algae colonize rapidly and can produce toxins that can harm humans and animals.
