The RainDance "RDWS-NS" Backwashing Sediment, Sand, & Turbidity Filters

Irrigation & whole house self-cleaning maintenance-free sediment filtration systems.

Compare The Difference: Single-tank sediment filters can’t backwash and filter your sediment water at the same time, so there may be times that untreated sediment flows into the plumbing or irrigation lines. Our Twin-tank systems such as the Twin RDWS-NS, offered by RainDance Water Systems, don’t suffer from this problem. They keep filtering high sediment in your well water 24 hours a day, seven days a week. Perfect for irrigation, large households, and high water usage applications.
Twin Sediment Filters
Why you may want to consider using a RainDance Twin Sediment Filter: The Twin Tank sediment filter provides an uninterrupted continuous supply of sediment free well water (*3-5 microns) to your home, business, irrigation systems or livestock waterers. The Twin RDWS-NS series has two tanks for removing sediment, sand, silt, and turbidity in your well water. Water is filtered in one tank while the other is in a standby mode. When the filtering capacity of the first tank is reached, the system automatically switches tanks. The first tank then starts the backwashing cycle. This cycle is repeated when the second tank reaches its capacity point. The perfect choice for households that use a lot of water, long periods of irrigation watering or where continuous water treatment is desired.

My well water changes throughout the seasons, can the RainDance sediment filter keep up? Well water users experiencing high sediment, silt, sand, and turbidity will love our automatic, self-cleaning, no-maintenance RDWS-NS sand sediment filtration systems. The RDWS-NS Series is easy to install and provides superior water filtration performance and solids loading capacity compared to conventional multi-media water filtration media due to its unique structure, allowing particles (sediment) to penetrate deep into the filter bed to provide greater filtration at higher flow rates. The hardness, stability, and high surface area of the filter granules makes it a perfect filtration media for virtually every application in the water treatment industry. High filtration performance water systems: 3-5 micron fine particle removal. High capacity filtration throughout the entire filter bed depth provides more than twice the capacity of multimedia filtration. High Service Flow at 3-4 times that of multimedia with superior filtration. Our RDWS-NS Series uses NSF Approved Certified 61 filtration media that can last up to 5 years - simple replacement - just add new filter media to tank!

The RainDance Twin Sediment Filter features two tanks for treating well water sediment & turbidity. Water is filtered in one tank while the other is in a standby mode. When the capacity of the first tank is reached, the system automatically switches tanks. The first tank is then cleaned and remains in standby until the second tank reaches its capacity point. By using two alternating tanks there is always one tank filtering water at any time of day.
When a standard single-tank water filter is backwshing, any water used during this time will be unfiltered and allows sediment and debris to get into your plumbing. A twin-tank system is a great option if you have high water usage or use water at unpredictable times and need filtered water at any time of the day or night.

How It Works: The RDWS-NS Series is considered a maintenance-free, high capacity, high flow sediment water filter. There are no routine filters to replace and requires no chemicals. The RDWS-NS Series will filter and clarify your water by filtering turbidity (cloudy water), sand, silt, sediment, and suspended solids in the water. It will also improve the color of your water. The RDWS-NS series is controlled by an automatic self backwashing control valve which will initiate a 10 minute backwash and then a 5 minute rinse (some applications require longer backwashes) approximately every 1-5 days depending on sediment levels.

The filtration media will need to be exchanged approximately every 3-5 years*. This is easily accomplished with the use of a wet & dry vacuum which you use to vacuum out the old filtration media from the top of the filter. You then replace it with a new bed of filtration media which will last approximately another 3-5 years*. Our media tank and control valve can be re-used with your new media - ensuring you our most cost effective, long-lasting sediment solution! This is the only maintenance that the system will require. *Some applications may require a more frequent replacement interval.
