The Doulton / British Berkefeld Model SS-2 Gravity Water Filter system is designed for use in situations where a reliable supply of treated drinking water is unavailable.
Designed for emergency use, rural water supplies and camping situations, the British Berkefeld SS-2 gravity fed water filter system turns untreated, contaminated water into pure, fresh-tasting drinking water.
The British Berkefeld gravity fed water filter can provide you with pure, drinkable, potable water – anytime - anywhere. Requiring no external plumbing, the British Berkefeld gravity fed water filter is great for camping and traveling! Just add water from a pond, creek, lake or other source into its upper chamber. The simple force of gravity filters the water into the lower chamber.
Gravity fed water filters are commonly used every day in households across the country, and are particularly effective on private well systems. The ease of operation, combined with a proven effectiveness at eliminating water-borne diseases such as cholera and typhoid has led to the gravity filter being the preferred unit for field operations by many of the world's major aid and emergency relief organizations.
The British Berkefeld gravity fed water filter is constructed of high grade, polished stainless steel making it hygienic, durable and easy to clean. The upper chamber fits into the lower chamber so transporting your British Berkefeld is easy. The lower chamber has a fill capacity of 3 gallons. (10 liters). The high grade stainless steel British Berkefeld SS-2 gravity fed water filter includes 2 Doulton Super Sterasyl filter elements, but can utilize up to 4 candles at a time. Each filter element is 7" long and water output approximately 5.5 gallons per day.
- 2 candles produce 11 US gallons (40 liters) per 24 hours
- 3 candles produce 16 US gallons (60 liters) per 24 hours
- 4 candles produce 21 US gallons (80 liters) per 24 hours
How the Doulton Super Sterasyl Ceramic Candle Filter Works
The filter consists of two containers. The upper chamber is filled with untreated water which gravity feeds through 2) Doulton / "Super Sterasyl" ceramic filter elements, or ‘candles’ into the lower chamber. The ceramic candles consist of a fine micro-porous structure, which forms a complete barrier to all particles larger than 0.9 microns in size (1 Micron = 1,000th of a millimeter). All particles above this size become trapped on the surface and within the ceramic material. A layer of bacteriostatic material prevents the growth of bacteria (mitosis) within the ceramic wall. The Doulton ceramic filter elements have an activated carbon core and are designed to remove chlorine, rust, undesirable tastes, odors and many organic chemicals. After passing through the filter elements, safe, filtered water collects in the lower chamber and is dispensed through an easy to turn On-Off spigot. The structure of the ceramic material is designed to be cleanable. Regular cleaning of the Doulton / Super Sterasyl ceramic element will allow its filtration efficiency to become regenerated. The elements may be cleaned over 100 times before replacement is necessary. The high-tech Doulton Ceramic elements feature a nominal particulate filtration efficiency rating of: >98% down to 0.2 microns, >99.9% at 0.5 microns, and >99.99% at 0.9 microns, which effectively blocks waterborne pathogens and clarifies the water, making the British Berkefeld a powerful filtration system! The durable Doulton ceramic filters can be cleaned over and over with a soft brush or Scotch Brite pad and the filter media in this product contains an effective antimicrobial agent. Each ceramic filter element will provide efficient filtration from 2,600 gallons to 15,000 gallons depending on water quality. Detailed assembly and operating instructions are included.
