A pool backwash tank works by collecting the dirty water from the pool's filter backwash process and allowing the solids to settle out, enabling the cleaner water to be reused.
The Process Explained
Here's a breakdown of how a backwash tank functions:
- Collection: The backwash water, which contains dirt, debris, and other contaminants removed from your pool by the filter, is directed into the backwash tank.
- Settling: Inside the tank, the water is held, allowing gravity to do its job. The heavier particles, such as sand, dirt, and algae, sink to the bottom of the tank. This process is crucial for separating the clean water from the waste. As the reference states: The water is collected in the tank and allowed to settle.
- Separation: Once the sediment has settled, two distinct layers form. The top layer is comprised of relatively clean water, while the bottom layer contains the settled solids.
- Re-use: The clarified water from the top layer can be siphoned off. As per the provided reference, Once the sediment and debris have settled to the bottom of the tank, the clean water can be siphoned off the top and re-used. This water can be returned to the pool or used for other non-potable purposes like watering the lawn, saving on water consumption.
- Disposal: The concentrated sediment at the bottom of the tank, which includes the waste from the backwash process, needs to be disposed of properly. The sediment and debris that have settled to the bottom of the tank can be disposed of properly. This can be done by methods that comply with local regulations.
Benefits of Using a Backwash Tank
- Water Conservation: By allowing the reuse of clarified water, backwash tanks significantly reduce water wastage.
- Environmental Friendliness: Less wastewater means fewer resources used, contributing to eco-friendly pool maintenance.
- Reduced Discharge: By capturing the sediment and preventing it from entering the local water system.
Practical Insights
- Tank Size: The size of the backwash tank should be appropriate for the size of your pool and the frequency of backwashing.
- Maintenance: Backwash tanks require periodic cleaning to remove accumulated sediment and ensure their optimal operation.
- Local Regulations: Always adhere to local regulations regarding the discharge and disposal of backwash water and sediments.
By using a pool backwash tank, you can effectively manage pool filter backwash water, conserve resources, and maintain an environmentally responsible pool.
