i) Rate of flow of water .ii) Air supply by cascading. This is monitored by checking DO level .Min DO should be 1 ppm.iii) Maintain records

5.CLARIFIER TANK:

i) Sludge: Sludge removal should be sufficiently frequent .Continuous removal reduces floating scum and results in a thick sludge.Chokagaes in the sludge line is to be observed regularly.

The mechanical sludge scrapper should be run continuously or at a predetermined intervals as designed.The wheel of the scrapper is to be replaced immediately if worn out.

ii)Algae and other solids, oil ,grease etc are to be regularly atleast once a week to be removed by brushing and hosing them without disturbing the tank contents. Inlet and out let channels should be kept clean atleast once a week.Paint regularly to avoid corrosion.

iv) Keep records of cleaning

6. Rapid Gravity Filter :

It requires regular backwash. Otherwise problems like air binding, incrustation of media etc. Backwash should be done at the designed pressure, not at low pressure for a long duration as is done as shortcut method.The time and duration of backwsh is depended upon the turbidity of wasted water. You should provide us with the backwash manual given to you by the consultant.

today joke--GOOD MORNING EVERYBODY

cell phones

I just barely dropped trousers&sitting down when I heard a voice from the other stall
saying:
"Hi, how are you?"

I'm not the type to start a conversation in the restroom, but I
answered, somewhat embarrassed,
"Doin! just fine!"

And the other person says:
"So what are you up to?"

What!, kind of question is that? At that point, I'm thinking this is too
bizarre so I say:
"Uhhh, I'm like you, just traveling!"

At this point, I am just trying to get out as fast as I can, when I hear

"Can I come over?"

Ok!!, this question is just too weird for me but I figured I could just
be polite and end the conversation. I say
"No!!........I'm a little busy right now!!!"

Then I hear the person say nervously...
"Listen, I'll have to call you back. There's an idiot in the other
stall who keeps answering all my questions!!!",

Cell Phones, aren't they great!!

The Test

Three men who were lost in the forest were captured bycannibals. The cannibal king told the prisoners that they couldlive if they pass a trial. The first step of the trial was to goto the forest and get ten pieces of the same kind of fruit. Soall three men went separate ways to gather fruits.The first one came back and said to the king, "I brought tenapples." The king then explained the trial to him. "You have toshove the fruits up your butt without any expression on yourface or you'll be eaten."The first apple went in... but on the second one he winced outin pain, so he was killed.The second one arrived and showed the king ten berries. When theking explained the trial to him he thought to himself that thisshould be easy. 1...2...3...4...5...6...7...8... and on theninth berry he burst out in laughter and was killed.The first guy and the second guy met in heaven. The first oneasked, "Why did you laugh, you almost got away with it?" Thesecond one replied, "I couldn't help it, I saw the
third guycoming with pineapples."

 very good article.. Please read through this....
 
EXTRACT FROM DOUG COPP'S ARTICLE ON THE "TRIANGLE OF LIFE", Edited by Larry
Linn for MAA Safety Committee brief on 4/13/04.


My name is Doug Copp. I am the Rescue Chief and Disaster Manager of the
American Rescue Team International (ARTI), the world's most experienced rescue team. The information in this article will save lives in an earthquake.

I have crawled inside 875 collapsed buildings, worked with rescue teams from
60 countries, founded rescue teams in several countries, and I am a member of many rescue teams from many countries. I was the United Nations expert in Disaster Mitigation for two years. I have worked at every major disaster in the world since 1985, except for simultaneous disasters.
             

In 1996 we made a film which proved my survival methodology to be correct.
The Turkish Federal Government, City of Istanbul, University of Istanbul Case Productions and ARTI cooperated to film this practical, scientific test. We collapsed a school and a home with 20 mannequins inside. Ten mannequins did "duck and cover," and ten mannequins I used in my "triangle of life" survival method. After the simulated earthquake collapse we crawled through the rubble and entered the building to film and document the results. The film, in which I practiced my survival techniques under directly observable, scientific conditions, relevant to building collapse, showed there would have been zero percent survival for those doing duck and cover. There would likely have been 100 percent survivability for people using my method of the "triangle of life." This film has been seen by millions of viewers on television in Turkey and the rest of Europe, and it was seen in the USA, Canada and Latin America on the TV program Real TV.

The first building I ever crawled inside of was a school in Mexico City
during the 1985 earthquake. Every child was under their desk. Every child
was crushed to the thickness of their bones. They could have survived by
lying down next to their desks in the aisles. It was obscene, unnecessary and I wondered why the children were not in the aisles. I didn't at the time know that the children were told to hide under something.

Simply stated, when buildings collapse, the weight of the ceilings falling
upon the objects or furniture inside crushes these objects, leaving a space
or void next to them. This space is what I call the "triangle of life". The
larger the object, the stronger, the less it will compact. The less the
object compacts, the larger the void, the greater the probability that the
person who is using this void for safety will not be injured. The next time
you watch collapsed buildings, on television, count the "triangles" you see
formed. They are everywhere. It is the most common shape, you will see, in a collapsed building. They are everywhere.

TEN TIPS FOR EARTHQUAKE SAFETY

1) Most everyone who simply "ducks and covers" WHEN BUILDINGS COLLAPSE are
crushed to death. People who get under objects, like desks or cars, are crushed.

2) Cats, dogs and babies often naturally curl up in the fetal position. You
should too in an earthquake. It is a natural safety/survival instinct. You
can survive in a smaller void. Get next to an object, next to a sofa, next
to a large bulky object that will compress slightly but leave a void next to
it.

3) Wooden buildings are the safest type of construction to be in during an
earthquake. Wood is flexible and moves with the force of the earthquake. If the wooden building does collapse, large survival voids are created. Also, the wooden building has less concentrated, crushing weight. Brick buildings will break into individual bricks. Bricks will cause many injuries but less squashed bodies than concrete slabs.

4) If you are in bed during the night and an earthquake occurs, simply roll
off the bed. A safe void will exist around the bed. Hotels can achieve a
much greater survival rate in earthquakes, simply by posting a sign on the
back of the door of every room telling occupants to lie down on the floor, next to the bottom of the bed during an earthquake.

5) If an earthquake happens and you cannot easily escape by getting out the
door or window, then lie down and curl up in the fetal position next to a sofa, or large chair.

6) Most everyone who gets under a doorway when buildings collapse is killed.
How? If you stand under a doorway and the doorjamb falls forward or backward you will be crushed by the ceiling above. If the door jam falls sideways you will be cut in half by the doorway. In either case, you will be killed!

7) Never go to the stairs. The stairs have a different "moment of frequency"
(they swing separately from the main part of the building). The stairs and remainder of the building continuously bump into each other until structural failure of the stairs takes place. The people who get on stairs before they fail are chopped up by the stair treads - horribly mutilated. Even if the building doesn't collapse, stay away from the stairs. The stairs are a likely part of the building to be damaged. Even if the stairs are not collapsed by the earthquake, they may collapse later when overloaded by
fleeing people. They should always be checked for safety, even when the rest
 of the building is not damaged.

8) Get Near the Outer Walls Of Buildings Or Outside Of Them If Possible
  - It is much better to be near the outside of the building rather than the
interior. The farther inside you are from the outside perimeter of the
building the greater the probability that your escape route will be blocked;

9) People inside of their vehicles are crushed when the road above falls in
an earthquake and crushes their vehicles; which is exactly what happened with the slabs between the decks of the Nimitz Freeway. The victims of the San Francisco earthquake all stayed inside of their vehicles. They were all killed. They could have easily survived by getting out and sitting or lying next to their vehicles. Everyone killed would have survived if they had been able to get out of their cars and sit or lie next to them. All the crushed cars had voids 3 feet high next to them, except for the cars that had columns fall directly across them.

10) I discovered, while crawling inside of collapsed newspaper offices and
other offices with a lot of paper, that paper does not compact. Large voids are found surrounding stacks of paper.
