Septic action is produced by the septic tank by __________ Correct Answer Anaerobic bacteria

Septic action is produced by the septic tank by anaerobic bacteria. In this, carbohydrates, proteins and fats present in the sewage are broken into simpler compounds. The nitrogen is converted into ammonia and the colloidal matter is flocculated, liquified and then finally digested.

Three pipes x, y and z can fill a tank A can fill it in 4 minutes. Two pipes p and q are connected to tank B. how much time does it take for both tanks to run at the full capacity? Ratio of time taken to fill tank A by P and time taken by x to fill tank A is 2: 1 and ratio of time taken by Q to fill tank B and Z to fill tank A is 5: 3. Pipe P is 20% more efficient then pipe Q. and pipe Y takes 12 minutes to fill the tank. Capacity of tank B is 3/4 times of tank A. Note: Tank B is to be filled only after filling tank A. Valves of pipe p and q are closed once tank B is running at full capacity.
Read the given statements and conclusions carefully and decide which of the given conclusions logically follows from the given statements. Statement: X tells Y, "Our society's septic tank is full and gutter water is coming out; the Society Association is not taking the necessary steps to clean the septic tank." Conclusions: 1. The septic tank can be full and needs to be cleaned or emptied. 2. The septic tank of the X's Society is not yet connected to the main gutter line of the municipality.
Two pipes are connected to tank 1 and one pipe connects tank 1 and tank 2 at the bottom of both tanks. At first pipe A and pipe B will filling tank 1 and then pipe C would be opened to fill tank 2. Capacity of tank 1 is twice capacity of tank 2. Pipe C takes 8 minutes to fill the whole tank 2 wherein discharging capacity of pipe C is 62.5 liters per minute. Ratio of time taken by pipe A and B to fill the tank when operating alone is 4 : 5 then find approximate discharging capacity of pipe A and B in liters/ minute if both the pipes discharge equal amount of water in tank. Time taken by pipe A and B to fill the tank 1 is 20/ 3 minutes
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Pipe A takes thrice the time taken by Pipe B to fill a tank. Together they can fill the tank in 15 hours, tank A and B is opened together for 4 hours and then Pipe A is closed and after 2 more hours Pipe B is closed and an outlet Pipe C is opened which when working alone can empty the tank in 10 hours. Calculate the time taken by C to empty the tank. Quantity B: A pipe A can fill the tank in 10 hours another pipe B can fill the tank in 15 hours and with the help of third pipe C they can fill the tank in 5 hours. Pipe A is opened for 4 hours then it is closed, pipe B is closed 3 hours before filling of tank and tank C is opened the whole time. Calculate the time taken to fill the tank

A tank has an optional adjustable outlet pipe that can be attached to the tank at any height we want. This outlet pipe drains water from the tank at a constant rate, while the tank is being filled using another inlet pipe at a constant rate. If the outlet, pipe is attached at half the height of the tank, the tank, which is initially empty gets filled in 18 hours. If the outlet pipe is attached at height equal to two third height of the tank, the tank, which is initially empty, is filled in 16 hours. In how many hours will the tank, which is initially empty, be completely filled if the outlet pipe is not attached to the tank?
A, B and C are 3 small pumps fitted to a tank. D is a large pump fitted to the tank. B is 50% more efficient than A. C is 33.33% more efficient than B. D is 50% more efficient than C. All of the pumps are used to fill the tank. Find the ratio of the time taken by all the pumps to fill the tank when pump D is used to empty the tank and other are used to fill the tank to the time taken when all are used to fill the tank?
Pipes A and B are used to fill the tank. A can fill the tank twice as fast as B. Pipe C and D can empty the tank. D takes same time to empty the tank as taken by B to fill it. Pipe C can empty tank in 6 hours. If all 4 are opened together, how much hour would it take to fill the tank? (Assume: D can empty tank twice as fast as C.)
The given question is followed by two statements; select the most appropriate option that solves the question. Capacity of a solution tank A is 70 % of the capacity of tank B. How many gallons of solution are in tank A and tank B? Statements: I) Tank A is 80% full and tank B is 40% full. II) Tank A if full contains 14,000 gallons of solution.
There are two inlet pipe in the tank which can fill the tank in 15 and 20 hours respectively. There are two leaks in the tank too, having same efficiency one at the bottom of the tank and other at 3/4th height of the tank. Find the time in which the tank will get filled, if the bottom leak can empty the tank in 30 hours.
