Chimo XterionTM Membranes
Leading Performance. Lowest Cost. Smallest Footprint.
Chimos patented Membrane Bioreactor (MBR) Systems consistently deliver industry leading performance at the lowest cost and in the smallest footprint. Treating wastewater means that organic material content (COD, BOD) and other pollutants (Phosphorus, Nitrogen, etc.) must be reduced to levels that meet or exceed standards set by local regulatory bodies. XterionTM membranes are employed in a process that uses bacteria to degrade these compounds, and is known to be the most effective and cost-efficient treatment method on the market. MBR systems with unique XterionTM plate and frame (flat) membranes are installed outside the bioreactor with the sludge pumped through the module at high speed.
Advantages of XterionTM MBR Technology
The XterionTM MBR technology provides the following advantages:
- External Installation: External membrane installation (as opposed to submerged membranes that need to be taken out of the reactor) allows for: easy and direct access for inspection and maintenance; separate control and inspection of each individual membrane plate; full modularity and easy expansion of wastewater treatment capacity; high degree of flexibility in the system for design and installation where space, and especially height, is limited.
- High Flow Rate: High flow rate and pressure feed of the reactor content (MLSS) into the membrane module enables high permeate fluxes (60-80 lit/m2*hr). As a result, the membrane area required for treatment of wastewater flow is much lower than most other membranes.
- High Circulation Speed: High circulation speed over the membranes (2 m/sec) reduces fouling accumulation and membrane cleaning (CIP) demand.
- Permeate Quality: The permeate quality is superb, even in very high sludge concentrations (up to 2%). The system consistently produces effluent that exceeds industry requirements (BOD < 5, TSS < 5). Besides BOD and TSS, the membranes also effectively filter bacteria and viruses.
- Solids-free Effluents: Absolute separation of biological sludge from the effluents by Ultra-Filtration (UF) membranes, producing solids-free treated effluents (permeate TSS < 5 mg/l).
- Less susceptible to upsets due to flow variations: The membranes are an integral part of the biological system and enables complete control of sludge concentration, sludge age, and many other parameters of the process. As a result, MBR systems are able to cope with changing variations in quality and quantity of wastewater, which is important especially in industrial applications.
- Small Footprint: Membranes can concentrate the biological sludge in the reactor to 1-1.5% solids, 2-4 times higher than in conventional systems. As a result, the system footprint can be relatively small and compact (45% less space required than conventional treatment plants).
- Lower Treatment Costs: Low production of excess sludge reduces overall treatment costs.
- Grey Water Uses: The effluent produced by our membrane system can be reused for toilet flushing or other industrial and grey water purposes. If requested, reverse osmosis can be applied to the treatment effluent to produce water that exceeds standards for Canadian drinking water.
- Less odor
Disadvantages of Competing Technologies (Immersed Systems)
Other available methods separate sludge from treated effluents using sedimentation and their ability to produce high quality effluent is limited, especially for complex industrial wastewater. Disadvantages of competing immersed processes include:
- higher equipment costs
- higher operating costs
- more equipment and space requirements (larger footprint)
- the need for additional and larger tanks because the systems work at lower concentrations
- the painful need to remove the membrane in order to clean
- maintenance is more time and labor intensive
Mobile Water and Wastewater Plants
Our fleet of portable wastewater treatment plants are engineered to process different volumes depending on your project. Units using our smaller membranes (Chimo Xterion CX7) can treat wastewater from 50 people to 500 people (up to 100 m ³/day). Units using our larger membrane series (Chimo Xterion CX9) are capable of treating wastewater for up to 7,200 people (up to 1,700 m ³/day).

Custom-Designed Plants Servicing up to 7,200 People
For longer term needs or where a permanent system is required, we design and build systems to suit the individual requirements of your project using our patented membrane technology. Each MBR system is tailor-made to the clients specific requirements, including pre-treatments (filtration, separation of specific pollutants), MBR process & engineering, and post-treatments (disinfection, desalination and effluent recycling). We also offer on-going service and support after a systems start-up.
