Do anybody have any informations on the flux of sand filter system?Varying flux in varying diameter?
Sand Filter System: Flux & Diameter
In summary, the conversation is about the flux of a sand filter system and whether there is any available information on its varying flux and diameter. One person suggests looking into Darcy's Law, while another suggests looking at engineering data provided by filter manufacturers, specifically mentioning flow and expected pressure drop. A filtration velocity of 15m/hr is deemed adequate.

Sorry, dude. I have no idea what you're talking about.

Well, since a sand filter is basicly water flowing throught sand of different grades, did you look up Darcy's Law?

What I actually looking for is, do anybody have any data or tables or figures about the normal flux that run through the sand filter...

If you look up manufacturers of particular filters, they will always provide engineering data on their performance such as flow and expected [tex]\Delta P[/tex].

15m/hr filtration velocity (superficial) is good enough.
1. What is a sand filter system?
A sand filter system is a type of water filtration system that uses layers of sand to remove impurities and particles from water. The water is directed through the sand, which acts as a physical barrier to trap and remove contaminants.
2. How does a sand filter system work?
A sand filter system works by passing water through a layer of sand, which acts as a physical barrier to trap and remove impurities. As the water passes through the sand, particles and contaminants are trapped, allowing clean water to flow out of the system.
3. What is flux in a sand filter system?
Flux refers to the rate at which water flows through the sand filter system. It is typically measured in gallons per minute (GPM) and is an important factor in determining the efficiency of the system.
4. How does the diameter of a sand filter affect its performance?
The diameter of a sand filter can affect its performance in several ways. A larger diameter filter will have a larger surface area, allowing it to filter more water at once. However, a smaller diameter filter may have a higher flow rate, resulting in more frequent backwashing and potentially better filtration.
5. How often should a sand filter system be backwashed?
The frequency of backwashing a sand filter system depends on several factors, including the size of the filter, the amount of water being filtered, and the level of contaminants in the water. Generally, it is recommended to backwash the system every 1-2 weeks to prevent clogging and maintain efficient filtration.
