Chemiles System Overview 

Chemiles System Process Flowchart

WP BackWash


Chemiles is a groundwater treatment system that does not damage the bio-filtration of sand layer. Its high velocity filtration will cause filter bed-clogging. Hence, backwash is necessary to solve this issue.

However, frequent backwash could damage the filter bed where 
bacterias are found. Therefore we adopt “WP BACKWASH” system as the solution that provides biological treatment with high filtration rate of 120-400m/day. 

P – Backwash (Portion Backwash)


P (portion) wash is mainly aimed at filter media surface (Iron Removal Layer) washing at 100-400 mm height.



Removal of iron sludge: 100 to 400mm of upper layer of filter



Step 1: Surface washing by rotating nozzles and slow upward flow of treated water


Step 2: Slow upward flow of treated water at reverse circulation of flow.









W – Backwash (Whole Backwash)

W (whole) wash is a general, powerful backwash. Mainly aimed at filter media washing and performed at a frequency that avoids damage to the bacteria performance.

To wash the entire layer of filtration sand

Step 1:
Surface washing by rotating nozzles and slow upward flow of treated water

Step 2: Intense upward flow to wash entire layer of filtration sand

Step 3: Slow upward flow to remove sludge released from Step 2
