Why is alum added to water?
Because water does not like to be alone.
It wants somebody’s company.
No. Alum is added to purify water.
Alum is aluminium sulfate.
It acts as a coagulant.
A coagulant attracts and binds with extremely fine and small particles to form a large particle.
I won’t use it.
But why?
Because it will attract all small insects and make a large insect.
You are just unbelievable.
When a solution of alum is added to impure water, it attracts and binds with contaminants and fine suspended particles of mud, dirt, etc. to form large particles.
Being large, these particles can be removed by filtration, or when they settle down due to gravity, they can be removed through decantation, giving us pure water.

About MCQ Bushcraft & Wilderness Life.
Hi my names Mike and I live in Northern Sweden, Welcome to my channel! My videos cover Bushcraft, wilderness survival and outdoor skills, bushcraft gear like axes, knives, saws, backpacks, clothing systems, shelters and cooking gear. Fire lighting with natural tinders, fishing and hunting, slingshot hunting, ice fishing, mushroom identification and plant identification, catching and cooking wild game, foraging and cooking wild plants and mushrooms, wilderness cooking, weaving and basket making.
My Wife Megan and I also travel throughout northern europe overlanding in our modified 4×4 exploring wilderness tracks and roads. We left the UK almost one year ago to travel and relocate to the North of Sweden where we now live in a remote town surrounded by wilderness. Outside of our working lives we spend out time exploring the wilderness, ice fishing and regular fishing in the summer over lakes and rivers, we regularly hunt with rifles and shotguns for various bird species and we enjoy hiking and camping with our bushcraft kit but also further afield with our modified 4×4 and roof top tent.
Thanks for reading and checking out the channel and feel free to have a look at the playlists and videos below.
Mike and Megan đŸ˜‰
