No. Spin-out filters are not recommended to remove algae. They do not perform well when pumping water from lakes, ponds, rivers, or other surface water sources where algae is present.
Spin-out filters are designed to remove large / heavy particulate utilizing centrifugal force, which is created by the spinning action which separates heavy particulate, such as:
- Sand
- Grit
- Rust
- Scale
They use a washable stainless steel mesh screen to capture these larger particles while allowing water to continue flowing through the filter.
Solutions for Pumping Water Containing Algae
Since algae will quickly accumulate on the stainless steel mesh, it will restrict water flow and cause a noticeable pressure drop. As the screen becomes clogged, the filter will require more frequent flushing and cleaning to maintain performance.
If algae is present in the water source, the algae needs to be removed before it enters the spin-out filter.
The use of a pump saver to prevent the algae from getting sucked into the pump’s intake screen or the foot valve screen when drawing water from lakes, ponds, rivers, or canals. A slotted pump saver screen is often effective when installed on the submersible pump to help keep algae, debris, and other large contaminants away from the pump’s intake.
A pump saver is a slotted PVC sleeve that fits over the submersible pump. Its large screen surface area allows water to enter at a much lower velocity than the pump's intake screen alone, helping reduce the amount of algae and debris drawn onto the screen while also protecting the pump from abrasive particles.
NOTE:
#1 - It is important to have the non-slotted section of pipe as long as the pump end and intake screen to keep the motor cool. Ensuring that water is drawing only from below the pumps intake screen, forces all the water to pass over the submersible motor improving the cooling properties.
#2 - Always refer to the submersible pump manufacturer's guidelines as to whether the pump can be operated in the horizontal position. Some pumps have bearings that require the pump to be installed vertically or at an angle to prevent premature bearing failure. This often requires the construction of a frame to which the pump can be secured.
For best results:
-
- Install the pump on a stand to keep it off the lake or pond bottom.
- Mark the pump location with a buoy for easier retrieval and maintenance.
In addition, if a spin-out filter is installed outdoors and exposed to direct sunlight, algae or bacterial growth may develop inside the clear housing over time. Installing a UV cover on your spin-out filter will block out the sunlight and help prevent algae and bacterial growth.
