CNYWAT aerator is device that introduces air into a liquid, usually water, to increase the amount

of dissolved oxygen in the water. This process is called aeration. Aeration can be done for various

purposes, including improving water quality, enhancing aquatic life, and increasing the

effectiveness of wastewater treatment. Aerators can come in various forms, ranging from simple diffusers that release bubbles into the

water to more complex devices that use mechanical means to mix air and water. Some aerators

are designed for large-scale water treatment systems, while others are intended for use in home

aquariums or small ponds. Aeration can be accomplished in several ways, such as surface aeration, where air is introduced

at the water surface, or subsurface aeration, where air is introduced below the water surface. Surface aeration is often achieved using fountains or waterfalls, while subsurface aeration is

accomplished using diffusers or mechanical mixers. Overall, aerators are essential for maintaining healthy water environments and are widely used in

both industrial and residential applications.

Biological fillers, also known as biofilters or bio-media, are materials used in water treatment to provide a surface area for the growth of microorganisms that can break down and remove organic pollutants from water. These materials are typically made of porous materials such as plastic, ceramics, or natural materials like crushed rocks or gravel.

The biofilm that forms on the surface of the biological filler provides a habitat for microorganisms like bacteria, fungi, and protozoa that can degrade organic contaminants. The microorganisms break down the contaminants into harmless substances such as water, carbon dioxide, and minerals. The efficiency of biological filtration depends on factors such as temperature, pH, dissolved oxygen levels, and the type of organic contaminant being treated.

Biological filters are commonly used in wastewater treatment plants, aquaculture facilities, and other water treatment systems to remove organic matter, ammonia, and other pollutants from water. They are also used in aquariums and fish ponds to maintain water quality and provide a healthy environment for aquatic organisms.

Overall, biological fillers are an effective and sustainable solution for water treatment, as they rely on natural processes to break down contaminants and require little maintenance compared to other treatment methods.
