Aquatic Eco-Systems’ Lakes Department has introduced the Mobile Alum Injection Device (MAID) to address various problems connected with high levels of pollutants or dissolvable nutrient loads in reservation ponds and storm water runoffs.
MAID at Lake Apopka Restoration Area
The MAID unit comprises an automatic remote monitoring system, a high capacity air compressor, liquid aluminum sulfate (alum) up to 5,000 gallons and a liquid dosing pump. The system injects flocculants to clear away materials from the water column and thus solves problems connected with pollutants and soluble nutrient loads in retention bonds and storm water. Technological advancements let the MAID system to fill a pond with required amount of alum depending on rainfall as well as flow data gathered by the MAID’ environmental monitoring equipment.
A liquid injection mixing appliance, as portion of the MAID unit, is utilized to add and distribute liquid alum all over the pond. The MAID system has the capacity to identify how much and when alum has to be injected using an automatic remote monitoring system that works jointly with in-pond mixing apparatus and the liquid dosing system to expedite injection. This procedure allows the submerged injector in the retention pond to scatter the injected matter property all over the water column. Flow rate and dispersal amount of the injection system gets adjusted automatically through shoreline controls.
The MAID system is safe to be used in counties and cities for construction discharge monitoring and wastewater compliance. It does not create unusable byproducts when using alum to refine the storm water runoff or retention pond. The pollutants and soluble nutrient loads that subside to the ground of the pond are finally removed, shifted and used in wastewater management facilities and wetlands.
Aquatic Eco-Systems is functioning along with the Orange County Environmental Protection Division at the Lake Apopka Restoration Area to help start a method for lessening pollutants in retention ponds and storm water runoffs.
