Odour Control Systems

Biorem’s Biotrickling Filters are designed for demanding applications of high concentrations of H2S or other water soluble compounds. We offer a range of structures and random packed medias to suit the specifics of your particular application.

Simple to operate, these systems are robust and effective for a variety of applications:

APPLICATIONS

• High H2S
• Methanol, MEK, Acetates
• Formaldehyde
• Ammonia (NH3) Removal
• Wastewater Treatment Plants
• Head Works
• Grit Removal
• Bar Screens
• Pumping Stations
• Pulp & Paper
• Biogas and Landfill Applications
• Industrial Applications for VOC Removal
• Roughing Filter

Features	Benefits
Small Footprint	Reduced footprint due to vertical design and lower EBRT due to efficiency of the synthetic medias
Low Life Cycle Costs	The ultra efficient design and synthetic media gives our biotrickling filters the lowest life cycle and operation costs
Energy Savings	The unit is designed with the media to have a low pressure drop which in turn means a lowers static pressure drop across the unit, ultimately saving money
Environmentally Friendly	No harmful or costly chemicals are used

Complex odors associated with various municipal wastewater treatment processes can be difficult to treat. That is why Biorem offers a robust and cost effective approach by combining our biotrickling filters and biofilter technologies. The first stage consists of a customizable biotrickling filter that is used as a roughing scrubber to remove elevated hydrogen sulfide concentrations, allowing the second stage biofilter to concentrate on the more difficult organic sulfides and VOCs.

APPLICATIONS

• Total Odor Removal
• Elevated Inlet H2S Air Stream
• Headworks
• Bar Screens
• Biosolids Management
• Grit Removal
• Pumping Stations
• Industrial Applications for VOC Removal

Features	Benefits
Handles difficult applications	Our dual stage systems can handle the most difficult air stream applications, providing long term consistent total odor removal
Variety of Reactor Types	Can be constructed using a variety of material types to meet budgets, delivery requirements and plant aesthetics
Media	The engineered mineral based media is homogenous and uniform in shape, providing consistent performance with less maintenance when compared to other media
Water recirculation system	Reduces wastewater generation and water consumption
Automated Controls	Operator friendly and compatible with most SCADA systems
Dual Stage	Handles peak variations, shock loads and process upset with ease

Untreated, contaminants found in biogas can cause significant, costly and irreversible damage to downstream equipment, resulting in an increase in costs due to repair, replacement and downtime. Biorem offers a proven, cost effective line of biogas conditioning systems designed to protect your equipment from the damaging effects caused by H2S, siloxanes and VOCs typically found in sewage, digesters or landfill gas. With increased knowledge of the need for energy independence and for the development of sustainable energy sources, biogas emissions can be converted to a valuable source of alternate energy.

Biorem’s ultrafiltration membranes offer important advantages over conventional filtration. These include an absolute barrier to pathogens, ability to treat a wide range of water sources and high tolerance for changes in feed water quality. Our membranes have a tight pore size and highly uniform pore structure. This provides superior control of all microbial contaminants including viruses, bacteria and parasites. It also reduces suspended solids content to less than 0.01 micron. Our systems operate in a dead-end, outside-in mode similar to conventional filtration. Benefits to our customers include high water recovery, consistent water quality, low operating cost and peace of mind.

We offer membranes in two chemistries. Our NIPS (Non-solvent Induced Phase Separation) membranes are asymmetric, are made from a highly hydrophilic PVDF chemistry, and deliver low fouling rates and low pressure drop. Our TIPS (Thermally Induced Phase Separation) membranes have highly uniform symmetric pores, and are five times stronger than NIPS membranes. This results in very high flux, long life and low maintenance requirements. Customer can choose the chemistry that suits his needs, as both are available in three standard module sizes.

The dead-end operation achieves very high recovery as all water fed during the filtration cycle is recovered as product. Periodic backwash using treated water dislodges solids accumulated in pores. This is followed by air flush of the outside surfaces to dislodge suspended solids sticking to the surface. A water wash then removes these solids from the modules. Chemically enhanced cleaning, in which a chemical is added to the backwash water, is also implemented to dissolve biofilm and colloidal solids in membrane pores. The modules are installed vertically to permit air flush and integrity test.

Modules are standardized to facilitate use as replacement in many existing systems. Biorem can also custom make modules to fit a specific project, if the size of the project justifies it. Modules are available in three lengths, each in a 0.225 m diameter to simplify installation. Product brochures are available upon request.

Biorem’s ultrafiltration products are being used in a large number of applications. These range from drinking water, seawater desalination, sewage treatment, water recovery, and industrial processes such as power generation and mineral processing.

Biorem is the leader in developing high performance, permanent filter media products. Biosorbens®, was brought to market 10 years ago as the first permanent biofilter media in North America and with it, Biorem has achieved recognized leadership in biofilter installations.

Today, Biorem continues to develop and commercialize top performing, proprietary filter media to provide the treatment of an ever widening array of air emissions. Biorem has expanded its product offering to include two new filter medias: XLD and LWE, which have higher performance efficiency, are more light-weight than Biosorbens® and are demonstrating strong customer acceptance.

The medias are engineered to exacting specifications, ensuring predictable and consistent performance in every application. Specifically designed for maximum removal efficiencies of odorous compounds, Biorem’s medias are all backed by a performance warranty.
