Sand Filter Overview
A sand filter with pump is an essential component of your pool’s treatment system, pre-treating the effluent from your septic tank before it flows to a soil treatment system. The sand used in a sand filter with pump removes solids, organic matter, and dissolved chemicals from your septic tank’s waste before it enters a soil treatment system.Sand filter with pumps come in two main types: single-pass and high-rate. Both type of sand filter with pump require regular cleaning to prevent clogging, though the sand in a high-rate filter must be cleaned more often.
Loading Rates and Filtering Efficiency
The sand in a sand filter with pump must be able to absorb a significant amount of the effluent. A sand filter with pump’s loading rate is usually expressed in terms of gallons per day per square foot of filter area.
Design Flow Rates and Backflushing
The design flow rate of a sand filter with pump is typically 15 gallons per minute per square foot of filter area. This is a safe and effective flow rate for a sand filter with pump, although if the water pressure drop in your sand filter with pump is more than 10 psi, you may need to backflush your sand filter with pump.Backflushing a sand filter with pump is a relatively simple procedure, as the sand is fluidized by the backflushing water. The backflushing water must be of sufficient pressure to carry out the contaminant removal in the sand, which is usually less than a psi.
What Is a Sand Filter Pump?
A sand filter pump is used to clean the water in a swimming pool or pond. It works by draining the water through a hose and into the filter. This high-efficiency system is a great way to save money on energy costs while keeping your pool or pond clean.
Sand filter pumps use sand, diatomaceous earth or cartridges filled with an accordion-folded screen to remove small particles in the range of 20 microns. These filters can last for years if they are properly maintained, but they require replacement every 2 to 5 years.
They are not as efficient at removing larger particles. To keep them functioning effectively, they have to be back-flushed regularly, with filtered water flowing through them in the opposite direction to release accumulated contaminants.
The sand in these tanks is specifically graded to trap particles between 20 and 100 microns. The sand has been designed to fit closely together and trap particles by binding them to each other.
These sand media are often used in a variety of applications and have been proven to be reliable and effective at removing many pollutants from water. They are especially important in drip irrigation because they can prevent emitters from becoming plugged with sand or other grit, which can lead to damage.
Backwashing Your Sand Pump Filter
The sand pump filter is one of the most important components in keeping your pool clean. It traps dirt, debris and floaters as the water flows through the filter. Without it, your pool can quickly turn from sparkling to dirty!
Sand pump filters use silica sand to filter your pool’s water. The sand is very fine and can hold particles as small as 20 microns.Each sand grain is covered with sharp edges that can grab dirt and debris. But as the sand filter works over time, these rough edges become worn down and smoother to the point where they can’t grab anything any longer.This clogs up your sand filter and reduces its effectiveness, which is why sand filter systems need regular maintenance. This maintenance is called backwashing and can be done manually or automatically.
