Onsite Pretreatment

Catalyze the digestive power of aerobic bacteria and worms to remove up to 99% of biochemical oxygen demand (BOD) and total suspended solids (TSS), and up to 95% for Total Kjeldahl Nitrogen and Fats, Oils, and Grease (FOG) in a chemical and sludge free filtration process.

Sustainability in Action

BioFiltro employs nature’s most effective cleaners, earthworms and micro-organisms, to enable clients to achieve profitable sustainability. Meet discharge requirements while minimizing wastewater management expenses, acreage used for land application, or industrial sewage discharge bills with our biofiltration process. 

Capable of processing millions of gallons per day, the BIDA® System uses up to 95% less energy than traditional wastewater treatment methods to deliver water that is ready for reuse, crop irrigation, or apt for tertiary disinfection. 

BioFiltro engineers custom design each BIDA® System to cater to the particular needs of each client. The modular design can meet individual household needs or that of multimillion gallon per day industrial clients.

How it works


How Does the BIDA® System Work?

The BIDA® System is a bioreactor that utilizes both physical and biological processes to provide secondary treatment. Physical filtration is provided by system medias which also cultivate a rich biomass of bacteria and worms for biological filtration. 

Telemetry Monitoring & Control

Using a network of sensors and control panels, BioFiltro remotely tracks system performance and water quality parameters.  Adjustments to system loadings can be made over the cloud to guarantee optimum performance. 

Primary Treatment

Solid separators are installed to prevent large solids from reaching the BIDA® System. Captured organic solids are transferred to secondary vermicomposting bins while water flows into an equalization tank where sensors monitor constituents such as pH and flow while bacteria is added as a nutritional supplement.

BioFiltration Layers

An automated irrigation system disperses wastewater across the entire surface of the BIDA® System. Gravity pulls the water through layers of wood shavings and river cobble before final discharge. Due to the rapid 4 hour process, the bioreactor is virtually odorless and requires minimum storage capacity. 

Earthworms & Microbial Bacteria

BioFiltro inoculates the surface of plant with an industry specific mix of worms and bacteria to achieve maximum reduction efficiencies on parameters such as BOD, TSS, FOG, Total Nitrogen, TDS, Ammonia, and Phosphorus. The burrowing worms create air channels, digest suspended solids, and can achieve densities of 12,000 worms per cubic yard. For seasonal clients, the biomass survives off of the carbon based wood shavings during the off season. 

Sustainable & Natural Byproducts

BioFiltro´s patented BIDA® System enable clients to filter water onsite, converting wastewater into a reusable asset and contaminants into a natural and nutritious fertilizer with high microbial count.
