REUSE WASTE WATER
Increasing pressure from population growth, changing weather patterns, and pollution are all contributing to a growing situation of water scarcity.
Membrane BioReactor (MBR) technology is a great solution to meet those needs and potentially reuse treated waste water.
Benefits of a MBR system
- High Effluent quality – potential for reuse
- Small Footprint
- Low sludge production
- High stability
Applications for MBR
- Decentralized commercial sites, such as shopping malls, hotels and resorts
- Military and relief aid camps
- Small municipal communities
- Industries such as food & Beverage, industrial laundries, the chemical and pharmaceutical sectors
- Sites that require upgrading to meet more stringent discharge quality levels
How Does the MBR Process Work?
CONVENTIONAL ACTIVATED SLUDGE WASTE WATER TREATMENT
In the Conventional Activated Sludge Method, sludge is separated into solids and liquid in a settling tank. This is called clarification.
MEMBRANE BIBIOREACTOR SYSTEM
The innovative MBR technology combines activated sludge treatment with solid-liquid separation by means of micro-porous membranes in place of the traditional separation by secondary clarification.
Advantages of MBR versus Conventional Activated Sludge (CAS) Treatment
The MBR process removes
the need for a separate clarifier
The ability to hold higher concentrations of MLSS and having longer sludge residence times allows the MBR to produce less sludge than conventional activated sludge systems.
High Effluent Quality
The flat sheet membranes used by Culligan have a pore size of just 0.15 µm resulting in clear, highly purified effluent.
Reduced Operator Input
The simpler process without the clarifier stage reduces the need for operator checks and adjustments.
The MBR process is stable across a range of conditions and can manage high levels of variability.
Membrane filtration – MFB-Cubo
MFB-Cubo is the system designed by Culligan for wastewater reuse. It is a solution that reduces the consumption of mains water by reusing properly treated wastewater that can be used for irrigation and washing water. Less waste equals greater efficiency, reduced costs (water and energy) and less environmental impact. MFB Cubo wastewater treatment systems provide filtered water free of suspended solids and low BOD and nitrogen concentrations. This technology allows the reuse of up to 90-95% of the water to be treated (which would otherwise be sent to the sewage system).
In addition to standard installations Culligan MBR systems are available in a wide range of configurations designed to meet your specific needs such as mobile containerized solutions for remote sites, or retrofit systems to enhance the performance of existing treatment plants.
Membrane Bio-Reactor systems from Culligan offer the latest technological solution to meet all waste water and water reuse needs.
