How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

First‚ the matting was placed on the four slides‚ cover-slips as well as the container of blood on top. Blood containers are in dropper bottles. Number each slide with a wax pencil. A drop of blood was placed on a slide and numbered it slide #1. Slide #1: 1. With the wooden applicator stick‚ dip the end into the blood and place a tiny drop onto slide #1 and put cover slip over it. Slide#2 1. Place 1 drop of 0.9% NaCl with the drop of blood (use the filter paper to absorb excess liquid). 2.

Lab Report: Hard Water Purpose: The purpose of this lab is to determine whether a liquid is hard water or not. Background: Hard water is the water that has a high amount of mineral in it‚ usually Ca2+ and Mg+. These cations enter the source of water by leaching from minerals within a wet underground layer of water- bearing rock‚ or an aquifer. According to the WHO‚ hard water is not harmful to human’s health but it’s a serious problem in the water industry. Household plumbing and appliances

Water has polarity. Polarity is the uneven distribution of charge. Water has cohesion‚ adhesion‚ and heat capacity. Cohesion is the attraction between molecules of the same substances. Adhesion is the force of attraction between molecules of a different substances. Heat capacity is the amount of heat it takes to raise temperature of a substance. The experiment displayed shows water can have adhesion and cohesion. The hypothesis of this experiment is if a nonpolar substance is added to water
