Comparison of Advanced Filter Layout vs. Traditional Sand Filters

Dimensional Comparison: Fiberglass Sand Filter vs. Advance Sand Filter

Distinctive Feature – Multiple Filters within a Single Shell

• Each filter contains 420 kg of silica sand

• Filtration Area Equivalence: 5 Advanced Filters = 1 Fiberglass Horizontal Sand Filter (3 meters long)

• Media Weight Comparison:

  • Advanced Filter: 2 tons of sand

  • Fiberglass Filter: 9.3 tons of sand and gravel

Efficiency of Filtration and Backwash Process

• Conventional Horizontal Sand Filter: Requires trapped silt to travel a long distance before exiting the filter during backwash.

• Advanced Sand Filter: Silt is expelled within a shorter 300 mm distance from the sand bed, reducing backwash time and conserving water.

• Overall, the Advanced Stainless Steel 316 Sand Filter is the most efficient sand filtration system available.

Ease of Maintenance and Sand Replacement

• Individual filters can be isolated and replaced separately, ensuring uninterrupted filtration.

• In a dual-bank setup of 5 filters each, only 1 filter (10%) is taken offline for media replacement.

• Minimal downtime: The filter is operational within three hours after replacement.

Efficient and Safe Sand Replacement Process

• Full access to the media bed eliminates the need for special ventilation equipment.

• Workers do not require additional protective gear for the replacement process.

Challenges with Traditional Horizontal Sand Filters

• Small access manholes require workers to enter the filter for sand removal.

• Media must be manually bagged and passed out, requiring extensive labor and ventilation for safety.

Backwash Water Consumption per Cycle

Traditional Horizontal Sand Filters (Mild Steel/Fiberglass)

• Duration: 15 minutes per filter (with air scouring)

• Water Usage: 30,000 liters (30 cubic meters) per cycle

• Without air scouring: 60,000 liters (60 cubic meters) per cycle

Advanced Stainless Steel 316 Sand Filter

• Duration: 10 minutes per filter

• Water Usage: 20,000 liters (20 cubic meters) per cycle

Annual Water Consumption Due to Backwash (55 Cycles per Year)

• Conventional Horizontal Sand Filter:

  • Air Scoured: 1,650 m³/year

  • Without Air Scouring: 3,300 m³/year

• Advanced Stainless Steel 316 Sand Filter: 1,100 m³/year

Summary of Cost Savings in Water Consumption

• Annual water savings range between 550 m³ to 2,200 m³ per filter.
