it sinks to the bottom
Water will freeze first, as sawdust does not have a freezing point. The freezing point of water is 0°C (32°F), while sawdust does not freeze but can become solid if mixed with water.
When sawdust is heated in water, it can absorb the water and swell due to the cellulose fibers present in it. As the temperature rises, the sawdust may release some compounds into the water through leaching. However, sawdust itself does not dissolve in water but can undergo physical changes like softening and expanding.
Filtering the waste water through sawdust will remove large pieces of solid matter (such as grit, paper etc).
Sawdust itself is not a gas. It is a mixture of small wood particles and can be considered a solid or particulate matter. When sawdust is burned, it can release gases such as carbon dioxide, carbon monoxide, and water vapor into the air.
Place the sawdust and gravel mixture in water and stir. Let it sit for a time - the gravel will fall to the bottom and the sawdust will float on the top. Density of gravel is greater than water and density of sawdust (wood) is less than water. The layer of sawdust can be carefully removed by skimming it off water's surface or by pouring gravel and sawdust through a series of mesh screens of varying size (the screens can be used with dry or wet mixture)I would use the difference in density of the two materials. A simple method would be to have a stream of the mixed materials poured from a higher elevation to a lower, with a stream of air blowing across the stream. Being less dense, the sawdust will be blown to one side, the gravel will drop straight down. Of course, you COULD just drop the mixed materials into water- sawdust floats, gravel does not. Sawdust will also burn, where gravel will not. Roasting the gravel at a heat above the combustion point of sawdust will cause it to ignite, burning the sawdust away, leaving gravel. Of course, if you have plenty of time, just turn a few termites loose on the mix- they will eat wood- but not gravel!
Sawdust typically floats in water due to its low density. When sawdust is mixed with water, it forms a suspension where the sawdust particles are less dense than the water, causing them to float.
When sawdust is mixed with water, the sawdust absorbs the water and swells up. This can result in the formation of a thick paste or slurry. Over time, the sawdust can break down and decompose in the water, potentially releasing nutrients and organic matter.
Water will freeze first, as sawdust does not have a freezing point. The freezing point of water is 0°C (32°F), while sawdust does not freeze but can become solid if mixed with water.
Most people think of something being soluble if it will dissolve in water. Sawdust doesn't dissolve in water. In general the cellulose and other structures that compose sawdust are not particularly soluble until they are broken down chemically - which is not really dissolving. Once they have been broken down, the resulting products can be dissolved - but at that point you aren't really dissolving sawdust anymore, you are dissolving the products of the chemical reactions that have broken down the sawdust.
Apply water to it or use high mass of sawdust.
Sawdust will not float in water. If you have some sawdust to dispose of, you should always place it in the proper waste containers.

Sawdust in water cannot be separated by sedimentation because sawdust is less dense than water, causing it to remain suspended in the water rather than settling to the bottom. The sawdust particles are too small and lightweight to separate effectively through sedimentation alone. Other methods such as filtration or centrifugation may be more suitable for separating sawdust from water.
Sawdust mixed in water cannot be separated by sedimentation because sawdust particles are too light to settle quickly in water. The buoyant force acting on the sawdust particles is stronger than the gravitational force pulling them down, so they remain suspended in the water for a long time. This makes it difficult for the sawdust to separate and settle at the bottom through sedimentation.
Sawdust does not dissolve in water because it is insoluble. Instead, sawdust will float on the surface or sink to the bottom of the water, as it does not chemically bond with the water molecules.
Filtering the waste water through sawdust will remove large pieces of solid matter (such as grit, paper etc).
Add the mixture of sawdust, sand and salt to water. The sawdust will float and can be skimmed form the surface. The salt will dissolve in the water. The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.
