Product Overview

This biotrickling filter treats H₂S-bearing exhaust collected from covered livestock wastewater tanks, pump pits and manure processing areas. A fan conveys foul air through a packed biological reactor while recirculating water keeps the media wet. The system can be integrated with wastewater treatment buildings, service platforms and steel structure farm facilities as part of a planned odor-control system.

Key Features

Fixed-film media provides surface area for H₂S-oxidizing microorganisms.
Vertical reactor configurations help conserve space at existing farm wastewater facilities.
Recirculating irrigation maintains contact between the biofilm, moisture and foul air.
Corrosion-resistant vessel, duct and piping materials can be selected for humid, sulfur-bearing exhaust.
Modular or project-specific layouts accommodate different airflow paths and available footprints.
Access points support inspection, media maintenance and routine servicing.

Structural Components

A typical system comprises a corrosion-resistant reactor vessel, structured or random packing, media support, irrigation nozzles, recirculation tank and pump, air inlet and outlet connections, drainage, inspection access and a control panel. Depending on the project, the supply scope may also include an extraction fan, demister, instruments, service platform and downstream polishing stage.

Working Principle

Collected foul air passes through wetted packing. H₂S transfers into the moisture layer and is biologically oxidized by microorganisms attached to the media. Recirculating liquid distributes moisture across the packing; a controlled bleed and make-up water arrangement manages accumulated dissolved byproducts. Treated air exits through the outlet duct. Actual removal performance depends on inlet loading, airflow, contact time, water quality and operating conditions.

Technical Specifications

Treatment airflow	According to project requirements
Inlet H₂S concentration	Confirmed by site measurement
Vessel arrangement	Customizable
Vessel and duct materials	Selected according to exhaust conditions
Media and irrigation design	According to project requirements
Electrical supply and controls	Available upon request
Climate protection	Designed according to local climate and farm conditions

Applications

Suitable for collected exhaust from pig farm wastewater treatment buildings, covered equalization tanks, lift stations, manure reception pits, solid-liquid separation rooms and related livestock effluent handling areas. Air collection and enclosure design should be coordinated with the building ventilation plan.

Customization Options

Reactor dimensions, media selection, fan duty, inlet and outlet orientation, access arrangements, control functions and optional polishing stages can be configured around the measured odor load and site layout. Connection details can be coordinated with the wastewater facility's concrete foundations, equipment rooms and steel structure service platforms.

Installation & Maintenance

The vessel is positioned on an engineered foundation and connected to the foul-air duct, water supply, drain, electrical service and controls. Commissioning includes checking airflow, liquid distribution and biological acclimation. Routine work includes inspecting the fan and pump, cleaning spray nozzles, monitoring pressure drop and recirculation conditions, and checking the media through the provided access points.

Product FAQ

Can the unit treat an entire pig house?
It is primarily configured for captured, H₂S-rich exhaust from wastewater and manure handling areas. Whole-house ventilation requires a separate airflow and contaminant assessment.

Is a water supply required?
Yes. The biological packing requires controlled wetting, with make-up water and a suitable drainage or bleed arrangement.

What information is needed for sizing?
Provide design airflow, measured H₂S and other odor concentrations, operating schedule, available footprint, climate conditions, water supply and the required outlet target.
