Advanced Membrane Bioreactor (MBR) Systems for Wastewater Treatment
Begin with an eye-opener: the pressures exerted on urban water systems by demands and tighter discharge limits are compelling the engineers to extract more action out of the treatment units - and membrane systems are responding to the challenge. At Hinada we integrate tight designs and strong membranes to provide constant high quality effluent, and the operations are simple to the operators. We put a higher value on practical results. The membrane bioreactor for wastewater treatment described here links biological degradation with fine membrane separation to remove solids and pathogens efficiently.
Product Snapshot and Technical Specifications Membrane bioreactor for wastewater treatment pairs suspended-growth biology with microfiltration or ultrafiltration membranes. Such a system eliminates close to all the suspended solids and biochemical oxygen demand (BOD) and turbidity is brought down to reuse or discharge without any harm. Unlike conventional plants that rely on clarifiers and tertiary filters, the membrane bioreactor for wastewater treatment accomplishes liquid-solid separation within the reactor, saving footprint and improving effluent consistency. 1.

These elements are suitable for lab tests, small packaged plants, and medium-to-large municipal or industrial schemes where a membrane bioreactor for wastewater treatment offers compact performance.
Key Operational Considerations The major limitation in operation is membrane fouling; air scouring on a periodic basis, automated backwash cycles as well as scheduled CIP, can reduce the accumulation and prolong their service life. To balance between permeate quality and membrane life, design flux and intermittent operation (as in the case of large systems; 7 min work / 1 min rest) can be used. To maximize the operation of membrane bioreactors in the treatment of wastewater, operators are supposed to record performance metrics. Typical working ranges: pressure 10-50 KPa, temperature 5-45degC, pH 1-10 depending on element selection for the membrane bioreactor for wastewater treatment.
Applications and Benefits
Suitable for municipal reuse, industrial process water, marine and containerized installations High solids retention reduces downstream filtration and improves pathogen control Smaller footprint and modular design support fast deployment where site space is limited and packaged solutions are needed Remote or containerized projects particularly benefit from membrane bioreactor for wastewater treatment modularity
Service and Support Hinada provides a design system, installation instructions, training of the operator and after sales service that is based on the project needs. In order to maintain long-term performance, our engineers suggest corresponding element options to feed characteristics and planning of the chemical cleaning periodicities. When specifying a membrane bioreactor for wastewater treatment, include fouling control measures and spare membrane inventory in the project plan.
Operational Tips (Quick Checklist)
Monitor transmembrane pressure (TMP) and flux trends to schedule cleaning before performance drops Keep oil and grease low (<5 mg/L) and screen influent to <2 mm to protect hollow fibers Automate backwash and air-scour cycles to ensure repeatable maintenance and reduce manual intervention
FAQs Q: How frequently are the membranes to be chemically cleaned? A: Cleaning rate is determined by the quality of feed and outcomes of monitoring; in most cases, a certain schedule of monthly or quarterly CIP cleaning is implemented by the performance indicators. Q: Are these membranes capable of dealing with the industrial effluent which contains heavy solids? A: Yes, under proper pre-treatment (screening, grit removal) and design modifications which would help reduce fouling. Q: How long is the membrane life supposed to last? A: The normal life cycle of a membrane depends on several years to a decade when it is operated, maintained, and replaced after every certain time.
