Product Description

100mm hollow hdpe black plastic shade balls for Reservoir Evaporation Protective are a type of plastic ball designed to cover water reservoirs or other storage facilities to prevent water evaporation, inhibit algal growth, and reduce the formation of harmful chemicals Below is a detailed introduction to shade balls:

Shade balls are typically made from High-Density Polyethylene (HDPE), a food-safe plastic that is BPA-free
They often have a black surface to absorb sunlight and reduce the amount of light entering the water


A standard shade ball has a diameter of about 4 inches (roughly 10 centimeters)

Application Method:
Shade balls are directly released into the reservoir, forming a floating cover
They are typically used for large open reservoirs but can also be applied to other water storage facilities


Reducing Water Evaporation: The covering of shade balls significantly diminishes direct sunlight exposure on the water surface, thus reducing evaporation
Inhibition of Algal Growth: Reducing sunlight penetration into the water can inhibit photosynthesis, thus decreasing the growth of algae
Preventing Harmful Chemical Reactions: Shade balls can prevent the formation of harmful substances like carcinogenic trihalomethanes, which form when chlorine and sunlight combine

Environmental Impact:

Shade balls have a minimal impact on the environment due to their stability and durability
However, regular monitoring and maintenance are still required to ensure they are not broken or damaged

History and Usage:

Shade balls gained significant attention in 2015 when the California Department of Water Resources released about 96 million shade balls into a Los Angeles reservoir to conserve water and improve water quality
I hope this information provides a clear understanding of shade balls If you need more specifics or have any other related questions, please let me know
