cordial greetings to the community of steemit I am new but taking my first steps here I am leaving this idea to survive in an unexpected moment and for which we will always need the vital liquid as it is the water, obviously before this problematic the water either of laughed, rain or dirty, is not safe at the time of consumption, they transmit diseases of water origin, for this you have to acquire some simple knowledge to purify and this suitable for human consumption here I leave my bit to help:
first we must locate 2 containers or containers, then use some fiber or micro fiber material, cloth, cotton, so collect different stones of different sizes, coarse sand and fine sand, the sequence of how you should use this is as follows select the largest container where you will remove the bottom part putting the peak of the container so down we place the microfiber, cotton or fabric, inside the container and press it strongly upwards we are placing the largest stones first to the smallest above then the coarse sand and then the fine sand finally we place the container on the other container so that it serves as receiver of the filtered water and will be ready to consume I hope it will be of great help and interest
