distill it- boil it and have a tube that goes through cool water and into an empty beaker. look up distilling
Filtration can be used to remove these substances from water.
pepper actually floats only some goes to the bottom in a water solution so after that you would need to filter the pepper and sawdust because it is larger and then evaporate the water.
It can't because of the solid particles of the pepper. This mixture is called a suspension.
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.
No. If you have a mixture of water and ground pepper, you can separate the pepper by pouring the mixture through a funnel lined with filter paper. The water will pass through the paper leaving the pepper behind.
Add water, stir til sugar dissolves, fiter repeatedly until the water is clean, slow evap to retrieve the sugar. Add the dust and sand from the filter (most will have separated pretty well, sand on bottom etc) into a cup/beaker/bucket etc and fill with water, put it in a deep tray and add water very slowly to the bucket until the sawdust has all spilt over the edge. Your sand will be in the bucket and sawdust will have overflowed into the tray.

you get watered-down 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.
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.
If the "plastic" sawdust truly is plastic, then it won't dissolve or go mushy in water. Real sawdust will.
it sinks to the bottom
Filtering the waste water through sawdust will remove large pieces of solid matter (such as grit, paper etc).
Use a magnet to separate the iron filings, filter the remaining sawdust and sugar water solution, evaporate the water from the sugar water solution.
