Multi-Stage Systems

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.

Ultrafiltration Solutions

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.


Module Surface Area, m2 Length, mm NIPS Maximum Capacity, m3/d TIPS Maximum Capacity, m3/d
KM 8060 60 2130 173 173
KM 8054 54 1860 156 194
KM 8078 78 2360 225 281

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.

Organics & Biogas Solutions

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.



A top performing, engineered inorganic permanent biofilter media which delivers consistent performance over the life of the media. BIOSORBENS® is ideal for applications where total odor removal is required. It is guaranteed to perform and carries a 10 year warranty.



The uniform and homogenous nature of this non-biodegradable media ensures even water distribution and superior predictable performance. The fluid nature of this media allows for easy installation and assumes the shape of the container. This property minimizes un-wanted voids and allows for uniform media distribution throughout the vessel.



A high performance engineered biofiltration media specifically designed for biosolids applications where the removal of high odor, low H2S and reduced sulfur compounds are critical. Total odor removal efficiencies of up to 99% can be achieved in 30 seconds and greater than 95% in 20 seconds or less, allowing XLD to achieve higher total odor removal in less than half the time of conventional inorganic biofiltration medias. XLD’s short retention times and lightweight design allows for small footprints and unique bed configurations to meet specific site requirements.
