MBR-C is a containerized MBR which utilizes hollow fiber (HF) ultrafiltration (UF) membranes with nominal pore size of 0.04 µm. In a typical MBR-C system, feed water passes through a drum screen to mitigate suspended solids and protect membranes’ surface. Water is then transferred to a bioreactor where microorganisms decompose organic content to mineral constituents of CO₂, H₂O, and inorganic nitrogen products at ambient temperature. Thereafter, water overflows to membrane tank(s), where UF membranes achieve complete retention of bacterial flocs, suspended solids, small colloids, and viruses.

Submerged HF Membrane Technology

MBR-C utilizes submerged membrane module (SMM) products featuring the best-in-class thermally induced phase separation (TIPS) polyvinylidene difluoride (PVDF), innovative modules, and skid designs to provide the most compact, simple, and reliable solution. SMM products are typically implemented in MBR applications treating municipal and industrial wastewaters. They are designed to effectively meet the needs of customers designing a new facility or replacing existing skids of any other manufacturer.

Advantages of MBR-C

MBR-C provides numerous advantages over all known biological treatment processes presently in use:

– Enhanced Membrane Technology

• TIPS spinning method → high tensile strength and long lifetime
• PVDF membrane material → higher chlorine tolerance compared to other membrane materials (e.g., PES)
• High packing density → fewer skids, smaller footprint, and higher productivity
• Patented air scouring technologies → low energy consumption
• Extreme caustic and oxidant tolerance → suitable for challenging applications
• Dense crystalline and monolithic structure → direct integrity testing capability

– Economy

• Integration of bio-treatment and membrane filtration eliminates the need for sedimentation tank and allows for compact design and installation.
• Minimal pumping requirements reduces equipment and operational costs.
• Lower sludge production rate, due to higher sludge age (i.e., SRT), compared to conventional activated sludge processes results in savings on disposal expenses.

– Smaller Aeration Tank and Footprint

• High mixed liquor suspended solids (MLSS) concentration and volumetric loading rate translate into compact footprint.

– Water of superior quality

• Membranes are capable of retaining activated sludge at high MLSS concentrations, leading to more effective BOD and nitrogen removal.
• UF membranes are capable of removing small colloids and viruses in addition to suspended solids and bacterial flocs.

– Ease of operation and maintenance

• MBR-C can operate largely unattended with the exception of occasional routine performance checks and maintenance of mechanical components.
• Segregated bioreactor and membrane tanks will allow for easy operation and maintenance.

That being said, it is vital to the preservation of the quality of your reverse osmosis membrane to pre-treat any materials that could harm reduce the effectiveness of the membrane itself. These materials may simply cause damage over time, or some may destroy a membrane outright.

Reverse Osmosis

Reverse Osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules. This is the reverse of the normal osmosis process, in which the solvent naturally moves from an area of low solute concentration, through a membrane, to an area of high solute concentration. The movement of a pure solvent to equalize solute concentrations on each side of a membrane generates a pressure and this is the “osmotic pressure.” Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis.

The process is similar to membrane filtration. However, there are key differences between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect exclusion of particles regardless of operational parameters such as influent pressure and concentration. Reverse osmosis, however involves a diffusive mechanism so that separation efficiency is dependent on solute concentration, pressure and water flux rate.

Pretreatment

Pretreatment is important when working with RO and nanofiltration (NF) membranes due to the nature of their spiral wound design. The material is engineered in such a fashion as to allow only one-way flow through the system. As such, the spiral wound design does not allow for back pulsing with water or air agitation to scour its surface and remove solids. Since accumulated material cannot be removed from the membrane surface systems, they are highly susceptible to fouling (loss of production capacity). Therefore, pretreatment is a necessity for any RO or NF system.

Pretreatment in SWRO systems has four major components:

• Screening of solids: Solids within the water must be removed and the water treated to prevent fouling of the membranes by fine particle or biological growth, and reduce the risk of damage to high-pressure pump components.

• Cartridge filtration: Generally, string-wound polypropylene filters are used to remove particles between 3 – 5 microns.

• Dosing: Oxidizing biocides, such as chlorine, are added to kill bacteria, followed by bisulfite dosing to deactivate the chlorine, which can destroy a thin-film composite membrane. There are also biofouling inhibitors, which do not kill bacteria, but simply prevent them from growing slime on the membrane surface.

• Prefiltration pH adjustment: If the pH, hardness and the alkalinity in the feedwater result in a scaling tendency when they are concentrated in the reject stream, acid is dosed to maintain carbonates in their soluble carbonic acid form.

CO_3-2 + H₃O+ = HCO₃– + H₂O
HCO₃– + H₃O+ = H₂CO₃ + H₂O

• Carbonic acid cannot combine with calcium to form calcium carbonate scale. Calcium carbonate scaling tendency is estimated using the Langelier saturation index. Adding too much sulfuric acid to control carbonate scales may result in calcium sulfate, barium sulfate or strontium sulfate scale formation on the RO membrane.

• Prefiltration antiscalants:Scale inhibitors (also known as antiscalants) prevent formation of all scales compared to acid, which can only prevent formation of calcium carbonate and calcium phosphate scales. In addition to inhibiting carbonate and phosphate scales, antiscalants inhibit sulfate and fluoride scales, disperse colloids and metal oxides, and specialty products can be to inhibit silica formation.

Dechlorination is a major advantage of multimedia filtration. Chlorinating water is a cost-effective way to disinfect it, but it leaves the water undrinkable, even toxic in high enough concentrations. Media filtration can take chlorinated water and purify it, not only eliminating chlorine, but depending on the types of media used, can eliminate colors, odors, tastes, suspended matter, silica, heavy metals, and acid content. Industrial media filtration can go with you wherever your needs may be when you use a CWT series mobile water filtration system from Pure Aqua.

Not only that, but there are a number of unique benefits to containerized systems that aren’t available to an in-room plant. Aside from the advantages that come from the portability of building a plant out of a forty foot container, containerized systems are entirely self-contained. Any pretreatment or multi-stage systems always go where your media filters go. A mobile water filtration system can even be designed with multiple tanks, allowing one to backwash while the others continue to provide high-quality product. The possibilities are endless.
