Primary wastewater treatment by dilution (Dilution) theory to develop due to the initiative of "bile expelling waste water" by the natural properties of gravity. (Gravity Flow)
The sewage by dilution (Dilution) along the theoretical development due. Works "better hydration waste water" using the natural force of gravity (Gravity Flow).
The principle of wastewater treatment by dilute (Dilution) along the development theory from. The Royal bile dehydrate them. " By using the principle of nature of earth"s gravity (Gravity Flow).
