Extracting Methane Gas from Household Waste

There are several process to extract methane gas from household waste. First, household waste patched into warming bed. In warming bed, part of household waste which can be used as fertilizer move to the fertilizer pipe, and in the other side, gas which still contain methane and dirt move to the next process, to the dirt trap. Dirt trap is a place to divide methane gas from unused dirt. The dirt thrown out through release cap and the methane gas go to the next step, Gas Indicator. In the Gas Indicator, methane gas passed through the water to purify the methane gas from the water vapor. Then the methane gas go to the last phase, to be kept in the Gas Holder. The normal pressure methane gas will keep in a big storage called Inner Tubes that have weight on top of it while the high pressure methane gas will move into the Pressure Release. We can use the methane gas in the storage any time by turn the gas tap.

Three Stages of Sewage Disposal Unit

There are three stages in the Sewage Disposal Unit. First, in the Settling Tank, sewage water which come from main sewer divided into polluted water and undecayed solids. The undecayed solids is removed and burned. The polluted water go to the second stage, the Pump House. In this stage, the polluted water just flows to the third stage through the pipe. The last stage is Sprinkler Beds. Here, jets of polluted water pass to the rotating arms. Then the water is filtered through stones and microorganism to produce the purified water. At the end, after pass three stages, the purified water flows to the river.
