Water treatment

Fat was dissolved in 25 mL of the solvent (a mixture of chloroform and acetic acid). Then, 1 mL of saturated solution of potassium iodine was added, and kept in a dark environment for 10 minutes. After this time, 20 mL of distilled water and 1mL of starch solution (1.5%) were added. The sample was titrated by 0.01 N Na2S2O3, until disappearance of the blue color. The amount of peroxide was calculated, using the following equation (Harold, Kirk, and Swayer 1981). PV = (1000 (푉1-푉2)…

The ancillary process for methanol production is purification. The aim of purification process is to separate the methanol from any impurities such as water, alcohol, alkanes, etc. Methanol is transferred to storage tanks which is specially assigned for crude Methanol. The Methanol will then be feed to the next part of the operation which is purification. In two different distillation columns, Methanol is purify to achieve the product quality which is required. In the first column, low boiling…

wide and their tentacles can stretch as long as 165 feet, according to National Geographic. Recent sightings of the Man O’War along beaches in Harvey Cedars, New Jersey prompted lifeguards to post information on its Facebook page where they issued water hazards and urged swimmers to be aware of their…

Water is in everything that we do. As you wake up in the morning one of the first things that you do is brush your teeth, another may be showering, or washing clothes that you plan on wearing that day. All of those daily activities are dependent on water. We as humans are completely and solely dependent on water as well. A human can survive only a very limited amount of time without water before our bodies begin to shut down. When it comes to surviving it is human nature to take care of…

“Oh, I have been in this group for more than 12 years” shared by a gentleman from a gambling anonymous (GA) group that I attended as a homework assignment. My first impression for group psychotherapy is that group will help people to reduce stress level without knowing how, why or what group counseling actually is. With the limited knowledge regarding group counseling, I am surprised to learn how much impact a support group can have for each person who participates. During the first lecture,…

Group 3: 10 units served as controls. Water samples from DUWLs and waste waters were collected every week during the ten weeks. They were inoculated onto various specific agar media and incubated at 28-37ºC for 2-7 days. After counting the colonies of microorganisms, they were identified and the mean…

1) The system that holds the fresh water making system shall be designed in such a manner to achieve 100% redundancy during installation. If the fresh water plant on board is less then 2, each plant should be able to produce and supply 100% of the ship’s total daily requirement. If the fresh water plant on board is more then 2, all plant should be of equal capacity with one plant being spare. 2) To prevent contamination of the water, the fresh water tank shall not be joined to another system…

the concept of climate change and the urban heat island effect? My understanding of the concept of climate change and the urban heat island effect is that they are both becoming more progressively harmful to our human health, the air we breathe, and water supply in our communities. Carbon dioxide (CO2) emitted from auto and factory emissions acts as a blanket, trapping long-wave infrared energy coming off the earth making our planet much warmer. Most radiation is absorbed by the earth’s surface…

strategies used to inactivate these enzymes. Vegetables are blanched before freezing and fruit can be dipped in a sugar syrup before freezing to keep them at their best. One of the main problems faced with freezing is a change in texture. When frozen water expands and can cause tissue damage. When the food is thawed it will be mushy and soft because of the tissue damage. When frozen slowly larger crystals will appear and cause more tissue damage. When frozen quickly the ice…

Water resource depletion: Resource depletion means the lack of that particular resource that is consumed faster than it is replenished. Thus, water resource depletion can be described as lack of water due to its excessive use or it can be said that water resource depletion occurs when water is wasted and over used. As water is most essential for all life forms, deficiency can be resulted into many issues regarding health and social life of people.…
