Low-Maintenance Wastewater Treatment with Trickling Filters
Trickling filters (TFs) provide a robust, cost-effective wastewater treatment solution. Used in small towns and industrial sites, they use a fixed-film process to remove organic matter and nutrients. With minimal energy and maintenance, TFs ensure reliable BOD and ammonia reduction. FILTEC designs and supplies trickling filter systems to meet diverse needs and environmental regulations.

How Trickling Filters Work
Trickling filters use a biological treatment process where wastewater is distributed over a bed of media, fostering microbial growth that breaks down organic pollutants. As water percolates through the media, bacteria and other microorganisms remove contaminants, reducing BOD and nitrogen levels. Unlike activated sludge systems, TFs operate without sludge recycling, require minimal operator input, and function efficiently under variable load conditions.
FAQs
How do trickling filters compare to MBR and SBR systems?
Trickling filters use significantly less energy and maintenance than membrane bioreactors (MBRs) and sequencing batch reactors (SBRs). MBRs provide higher effluent quality but need intensive aeration and membrane cleaning, while SBRs require more operator attention. Trickling filters offer a passive, low-energy solution for sites with limited operational resources.Â
What are the main advantages of TFs for wastewater treatment?
TFs provide energy-efficient biological treatment, require minimal maintenance, and deliver consistent BOD and ammonia reduction. They are well-suited for small communities and industrial sites where operational simplicity is a priority.
Can a TF system be retrofitted into an existing wastewater plant?
Yes, TFs can be integrated into older treatment plants to enhance performance without major infrastructure modifications. FILTEC designs retrofit solutions to improve capacity and effluent quality with minimal disruption.
What kind of wastewater is best treated using trickling filters?
Trickling filters treat domestic wastewater and high-organic-load industrial effluents, including food processing, breweries, and pulp & paper. They are ideal for applications requiring a passive, biological treatment approach with reliable performance and low energy use.
Do trickling biofilters require frequent maintenance?
Trickling biofilters require less maintenance than activated sludge and membrane systems. Routine checks include media condition assessments and ensuring even wastewater distribution. FILTEC offers servicing and upgrades to optimize performance over time.
