HOW WATER FILTRATION WORKS
No matter weather they are using sand, cloth, ceramic or membrane element, the principle is the same. It is all about the size of the pores which determine the cleanliness of the water.
NO ROCKET SCIENCE
To have fast water flowing rate…
Use clean water to filter (treated tap water)
New and clean filter element (wash more often)
Use filters with larger pores (high microns)
Increase higher water pressure (using pump)
Lower quality filtered water.

PRACTICALITY, EFFICIENCY, COST, MAINTENANCE...
Big project like these are good initiatives but not practical.
They were not sustainable because of high maintenance cost and expensive replacement parts.
CENTRALIZE WATER FILTER STATION
Specifications:
Centralize Water Filter Station
Type: Ceramic / UF Membrane / Sand
Power source: Gravity feed
Porosity: Depending on the filtering element used
Capacity: Variable
Water output: Depending on the condition of the filtering elements
Benefactors: Government agencies, NGO, Corporations
Setback:
1. High cost to build. Require infrastructure
2. High maintenance cost. Expensive replacement parts
3. Require laying of long pipes which often leak and break.
4. Water source from the river become muddy when it rain.
5. Input water quality is not controllable. The water container need to be wash regularly.
6. No water feed during dry season.
7. Clean water is not pipe to individual houses and many can be a long distant from the filter station.
8. Maintaining the facility will be the biggest challenge.
