Slow sand Filter - Garside slowfil

Garside Slowfil is a specially blended clean washed sand specifically produced for use in Slow Sand Filters. The sub-angular to rounded grain shape, petrological composition, high silica content and cleanliness make our sands ideal media for water filtration.

Slow sand filtration is a time-tested, reliable, and cost-effective method for purifying water. This method involves the gradual percolation of untreated water through a bed of fine sand, which naturally removes contaminants without the need for chemicals. With a design that is simple yet highly effective, slow sand filtering systems are ideal for both small communities and larger-scale applications.

Sustainable

 Slow sand filters are economical to build and maintain, especially in areas with low labor costs and available land. They require minimal power and no chemical additives, making them an environmentally friendly and sustainable choice for water treatment.

Low Maintenance

One of the standout advantages of a slow sand filter is its low maintenance requirements. These systems operate efficiently without the need for constant supervision, and sludge handling is minimal. The occasional replacement of sand is straightforward, and automated backwashing can further simplify the process.

Highly Effective

Slow sand filtering is incredibly efficient at removing contaminants from water. It can eliminate up to 99.9% of bacteria, and even improves the taste, odour, and colour of the water. Additionally it helps lower the risk of harmful disinfection byproducts in the treated water.

Why Choose Garside Slowfil?

Slow sand filtration is a biological process where untreated water passes slowly through a sand bed. As water moves through the fine sand, a biofilm layer forms on the sand grains. This layer is crucial, as it traps and consumes pathogens, ensuring the water that emerges is clean and safe. With a filtration rate much slower than other methods, slow sand filtration is particularly effective in removing a wide range of contaminants, making it an ideal choice for providing safe drinking water.
Garside Slowfil delivers outstanding results, effectively removing bacteria, viruses, and other contaminants while reducing the need for additional disinfection. This not only enhances water quality but also minimises harmful byproducts, making slow sand filtration a reliable, sustainable solution for clean water.
