By gravity with pressure of more than 15 psi, in case of installation in a multi storied building for example, the flow would be 40~50 Lt./hour.
Gravity pressure is 0.43 psi per foot for fresh water and 0.44 psi per foot for sea water.
So,for each additional 10 feet of height, figure about 4.3 to 4.4 psi increase in pressure.

This system has been designed for use with and without electricity or available running water.
There are two systems and both are manually operated during backwash and cleaning.
First one is made as per design FI-1005A with three stages of filtration plus UV (optional).
Second one is made as per designFI-1005D with 4 stages of filtration plus UV (optional).
This system can be utilized in the treatment of difficult feed waters with high degree of suspended solids such as: muddy water, flood water, storm water run off, rural water source like containment pond water etc.
