Slow Sand Filter
In the realm of water treatment, few technologies stand the test of time like
slow sand filters, These ingenious systems harness the power of nature, employing layers of sand and gravel to purify water through a combination of physical and biological processes.
Renowned for their simplicity and reliability, slow sand filters offer a beacon of hope for communities seeking sustainable water treatment solutions. With minimal energy requirements and a proven track record of efficacy, these filters emerge as the ideal choice for pre-treatment applications in smaller communities or remote locations.
Tikal Design Features
- Flow Rate: Slow sand filters operate at significantly lower flow rates, typically in the range of 0.1 to 0.3 gallons per minute per square foot (gpm/sq ft).
- Mechanism of Filtration: Slow sand filters employ a combination of physical and biological processes, the top layer of the filter bed develops a biological layer called the “schmutzdecke”, consisting of microorganisms that contribute to the breakdown and removal of organic matter.
- Maintenance: Slow sand filters typically require less frequent maintenance, The regeneration of the biological layer is a natural process, focusing on occasional scraping and cleaning of the top layer.
- Applicability: Slow sand filters are well-suited for smaller-scale applications, decentralized water treatment systems, and situations where a more natural and biological approach to water treatment is desired.
