Laboratory testing brings a lot of benefits to modern society. It is normally used in a lot of industries such as water treatment, food & beverages, and pharmaceuticals. Depending on what these industries require, scientists can perform several experiments in their labs using high technology equipment.
Here are examples of what's done inside a laboratory:
This is a method that shows how much light can be absorbed by a chemical substance. This is done by directing a beam of light at the substance, and then measuring the intensity of that light as it passes through it. This can be used in water analysis to test the quality of water, whether it is potable or not.
A jar test is done to find out if a water treatment plant is using sufficient amounts of chemicals when they treat raw water. This is normally done by putting water samples into beakers or jars. The containers are then stimulated to observe if there are flocs or particles that may form. Flocs forms when the material in raw water, like dirt particles, react with the treatment chemical used to treat the water.
In water treatment, sludge is a sort of wet mud mixed with lots of other liquids including water. Because sludge is toxic, water for treatment needs to be separated from it. This can be done through polymer screening, which involves the use of polymer or a material that can cause sludge to release water faster.
Another process that is done in labs is testing the strength and quality of materials to be used in the aforementioned industries. For example, filter underdrains are tools that are installed on existing filters to help them in the separating foreign particles from liquids, such as water. These four processes ultimately benefit society by ensuring that the products or consumables they get are of high quality and not dangerous to their health.
