Answer:
All things are transient in life. Whether it’s success or failure, happiness or miseries nothing is permanent. Even life itself is transitory. Crying is not the only solution for our problems. Crying will not bring the things for us for which we cry, instead if we try our best we might get what we desire.
It is not always possible to be happy or successful. It is a fact that if we want to get something, we have to face hurdles. However, there are many people who break down at the slightest strike. Everyone wants to be happy or successful. However, one does not realize that it is not possible to be successful or happy all the time. There will be ups and down in life. Even when we are successful there will be critics. So, when we meet failure instead of cursing our destiny and crying, it is better to fight back the situation. We should go on trying till we achieve the thing we dream of. However, if we are failing it does never mean that we don’t have potential. It just might be that our attempt was not in the right direction.
Failure is not ultimate. We must not forget the story of Robert Bruce and the spider. Instead of sitting back after failure and repenting, he tried and fought back with courage, and he won. We should not accept life as it comes to us. Why not try and see one more time? We should have faith on our potential. Thomas A. Edison said “our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.”

CONVENTIONAL WATER TREATMENT: COAGULATION AND FILTRATION FACT SHEET
WHAT IS THE CONVENTIONAL METHOD TO TREAT WATER?
Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. Worldwide, a combination of coagulation, sedimentation and filtration is the most widely applied water treatment technology, and has been used since the early 20th century. For more information about the disinfection portion of the treatment process, see the Chlorination fact sheet.
WHAT IS COAGULATION?
The coagulation process involves adding iron or aluminum salts, such as aluminum sulphate,
ferric sulphate, ferric chloride or polymers, to the water. These chemicals are called coagulants, and have a positive charge. The positive charge of the coagulant neutralizes the negative charge of dissolved and suspended particles in the water. When this reaction occurs, the particles bind together, or coagulate (this process is sometimes also called flocculation). The larger particles, or floc, are heavy and quickly settle to the bottom of the water supply. This settling process is called sedimentation. The following diagram illustrates the basic reactions and processes that occur during coagulation.
