Technology about water purification was discovered by the human hundreds years ago. One example of water purification technology is sewage disposal unit. Sewage disposal unit is consist of three main parts : settling tank, pump house, and sprinkler beds.
In the first of purifying process with sewage disposal unit, sewage is flown to the settling tank from main sewer . In the settling tank, sewage component will be separated in two form. The solid form called undecayed solids will move into the base of settling tank and then will be burned and removed. Next the liquid component called polluted water will be flown into pump house. In the pump house, polluted water will be pumped into sprinkler beds. In the splinker beds polluted water moves to the rotary arm which can directs the polluted water to the filtering zone. In the filtering zone, polluted water will be filtered from microorganism and stones. The result of this filtering process is purified water and will be flown into the river.

I have a blog containing good information on global warming. Ozone has doubled since the mid-19th century due to chemical emissions from vehicles, industrial processes and the burning of forests, the British climate researchers wrote. Carbon dioxide has also risen over that period. History of global warming is very deep since 1850.
