Shade Balls for evaporation problems
The Shade Balls have been around for quite a while, either known by different names or to serve different purposes. They've been around for quite some time, but they haven't been used to prevent water from evaporation.
Initially, they’ve been used to cover the open reservoirs in LA since back in 2008 because at that time the Ivanhoe Reservoir registered high amounts of bromate. Bromate is a carcinogen substance that forms as the result of a chemical reaction between bromide, chlorine, and sunlight, so then, they had to separate the water from the sunlight so they had to separate the water from the sunlight.
They also serve as an air-water separation mechanism and keep the air-born dust, dirt and grime out of the water, which is another advantage of using the Shade Balls. If there is a lower amount of water or a lower amount of turbidity that has to be filtered, they ultimately save a lot of money out of pumping cost. Because all that water from a reservoir has to be filtered somewhere along the line and the cleaner the water is the less pressure it takes to drive it through their filters.
Shade Balls can prevent evaporation problems. By being used to separate the water from the heat of the sun, the average temperature of the surface water is going to be kept lower, and therefore, there is going to be less evaporation. By avoiding evaporation you will save a lot of water, and they are looking at millions of gallons of water being saved.
