kyonki... KAL HO NAHO

i was a very sincere and honest child, people and my class mates used to call me mahatma gandhi.i always excelled in whatever i do.my struggle period began after i passed my tenth class in first division. i studies gone downhill in my class twelfth.

the only thing i regret is not having enjoyed college time and my youth. when my friends used to take their girlfriends out on long drives.i used to search for work.in the work people used to show attitude and i used to feel --i am a school topper and these semi literate people are treating me so badely. so there were ego hassels also.. i am sleepwalikng through my life. i am waitinmg for my death. that is a reality and the sooner we accept it, the better it is.that is why i work like a maniac..i dont know what will happen tommorow and i want to make the most of the time i have,i know tomorrow will never come.LIFE IS TODAY. at times i wonder why people are afraid of dying.actually i feel that only after dying one gets to know their reality as they can see everything--how they lived,how they behaved with other people and how they worked.One can only judge oneself after living a whole lifetime

THES ARE THE WORDS OF SONU NIGAM....Surprisingly they resembles my own thoughts and struggle process.

HEART OF THE MATTER--SAVE HEART MISSION

1.Touch and be touched:
studies have shown that people who are touched lovingly every day had significantly lower heart problems.

2.eat SEAWEED:
they have been shown to stabilise blood pressure, regualte levels of triglycerides,phospholipids,cholesterols.they dissolve any fatty buildup in the blood vessels, restore cardiac efficiency and prolong the life of the heart muscle.

3.eat GARLIC:
studies confirm garlics ability to lower blood pressure,reduce phospholipids,cholesterol, strengthen heart action,increase immune response,reduce platelet clumping and clotting (thus reducing strokes) and stabilise bloodc suger levels.Eat GARLIC raw or lightly cooked, several cloves a day.

4.Go for a WALK:
move. go for a walk. do it. regular exercise is key.

UASB DESIGN PARAMETERS

UASB Design
In general, there are two ways to design an UASB reactor
If input COD: 5,000 - 15,000 mg/l or more, the design method should be used based on Organic Loading rate, (OLR) If input COD < 5000 mg/l, the design method should be calculated based on velocity.


Some H2S gas can pass the GSL separator and accumulate above the water level in the top of the reactor. This will be oxidized to sulphate by oxygen in the air to form Sulphuric Acid that will in turn cause corrosion of both concrete and steel. Below the water level: Calcium Oxide, (CaO), in concrete can be dissolve with by Carbon Dioxide, (CO2), in the liquid in low pH conditions. To avoid these problems, the material used to construct the UASB reactor should be corrosion resistant, such as stainless steel or plastics, or be provided with proper surface coatings, (e.g. coated concrete rather than coated steel, plastic covered with impregnated hardwood for the settler, plastic fortified plywood, etc).
Operation
Operation criteria: The optimum pH range is from 6.6 to 7.6 The wastewater temperatures should not be < p =" 350"> 20oC) and sometimes the start-up can take up to 3 – 4 months. In start-up process, hydraulic loading must be Ј 50% of the design hydraulic loading.
The start-up of the UASB reactor can be considered to be complete once a satisfactory performance of the system has been reached at its design load.
