Which country has the best wastewater treatment system?

|Country||Current Rank||Baseline Rank|
What is the latest technology in wastewater treatment?
To address these new challenges, a variety of new wastewater treatment technologies such as membrane filtration systems, automatic variable filtration (AVF), advanced oxidation processes (AOP), UV irradiation has been proposed, tested and applied to meet both current and anticipated treatment requirements.
Does Bangkok have a sewage system?
Wastewater and used oil is discharged directly into the public sewerage system. The city’s underground sewerage system is interconnected like a spiderweb. This means that scum and sludge from one place flows into the whole system.

Blue Plains Advanced Wastewater Treatment Plant
DC Water’s Blue Plains Advanced Wastewater Treatment Plant is the largest plant of its kind in the world. On an average day, the facility treats close to 300 million gallons of wastewater and has the ability to treat over 1 billion gallons a day at peak flow.
What are wastewater treatment technologies?
3.1 Wastewater treatment technologies
|Process||Oxygen Supply||Removal Efficiency|
|Ascendant flow||Anaerobic||50%-60% organic matter 57% suspended solids|
|Anaerobic filtration||Anaerobic||40%-50% organic matter 52% suspended solids|
|Septic tank||Anaerobic||25% organic matter|
|Hydroponic cultivation||Aerobic/anaerobic||65%-75% organic matter|
What are the disadvantages of wastewater treatment?
Wastewater treatment plants are not suited to every home and have some disadvantages which need to be considered by anyone considering installing a system.
- Routine pumping out.
- Installation costs.
- Sporadic use.
- Treated water absorption.
Where does Bangkok get its water?
It is estimated that 75 percent of domestic water is obtained from groundwater sources. The groundwater system in Thailand is mainly recharged by rainfall of about 40 000 million m3 and by seepage from the rivers.
Which city has best drainage system in world?
Seawater flushing Other cities use treated wastewater for sewage, or desalinated seawater, but Hong Kong is the only large city in the world that has built a whole sewage system around the use of minimally treated water drawn from the sea that surrounds it. It is a remarkable achievement that began back in the 1950s.
How did we handle human waste before plumbing?
