Pile cloth media filtration compared to sandfilters

Key Advantages of Pile Cloth Media Filtration

• Superior Filtration Performance
  • Unlike traditional sand filters, pile cloth disc filters use finely woven cloth media to capture microscopic particles as small as 10 microns. This technology consistently meets or exceeds effluent quality standards, even at varying levels of influent quality, making it ideal for facilities with fluctuating wastewater characteristics.
• Reduced Footprint
  • Pile cloth disc filters are designed with a compact, modular structure, which requires significantly less space than sand filters. This allows facilities to achieve high filtration capacity within a smaller footprint, maximizing available space and reducing installation costs.
• Efficient Backwashing Process
  • Sand filters demand frequent, high-volume backwashing, which can lead to increased water and energy consumption. In contrast, pile cloth media filters employ an on-demand backwashing system using filtered effluent, minimizing water usage while maintaining continuous operation and higher overall system efficiency.
• Enhanced Load Handling and Chemical Compatibility
  • Pile cloth disc filters like the AquaDisk and Hydrotech Discfilter models have demonstrated exceptional performance in high-solids environments. During pilot studies, these filters adapted to influent variations and optimized chemical treatment to maintain effluent clarity, ensuring the filtration process remains effective under challenging conditions. AquaDisk, for example, can maintain effluent quality at turbidity levels below 2 NTU even under increased influent solids, with a lower demand for chemical intervention than sand filters.

Meeting Regulatory Standards with Ease

• Pile cloth media filtration is proven to meet California Title 22 standards for unrestricted wastewater reuse. This makes it ideal for facilities aiming to achieve high-quality effluent and stringent environmental compliance with minimal operational challenges.

2. Low Maintenance and Operational Costs

• The advanced backwashing system of pile cloth disc filters minimizes maintenance needs and operational costs. Unlike sand filters that require periodic full backwash cycles, pile cloth filters use a precise vacuum system to remove solids, reducing downtime and conserving resources.

3. Resilience During High Load Conditions

• In wastewater facilities, sudden increases in influent solids or plant upsets can compromise filtration quality. Pile cloth filters handle such scenarios more efficiently than sand filters, maintaining consistent effluent quality with the aid of optimized chemical dosing, if necessary.
