Today, with increasingly stringent regulations and the quick adoption of membrane filtration, the pressure is on for all stages of pretreatment chemical feed, flocculation, sedimentation and filtration to act in concert. In response, Meurer Research, Inc. has developed MRI Flocculation Systems integrating essential flocculation components into multi-stage systems with self-cleaning hydraulic final stages, maximizing versatility and performance. Optimize pretreatment with multi-stage MRI Flocculation Systems. MRI s innovative multi-stage flocculation system eliminates the trade-offs typically associated with G-value turbulence and delivers maximum control and efficiency for every pretreatment stage. By staging mechanical and hydraulic flocculators and leveraging a maximum range of G-values from 2,000 to 0 MRI Flocculation Systems help operators fine-tune flocculation. In addition, MRI partners with specialty chemical manufacturers to provide systems with superior ability to accommodate seasonal changes in raw water conditions. MRI Flocculation Systems include: Extremely high-g vertical turbine mixers for rapid mix stage High-G vertical turbine for first-stage flocculation Mid-G horizontal paddle wheel mixers for second and third stages Extremely low-g hydraulic mixer for combined final stage and buffer zone MRI Scraper with hinged bottom plank for final stage sediment clean-up Ported or serpentine baffles for stage separation Option to mix & match for enhanced effectiveness Mix & Ma t c h On l y f r o m MRI Hi g h e s t Mid Lo w e s t Se l f-cl e a n i n g G g-va l u e G-Va l u e G-Va l u e Hy d r a u l i c Fi n a l St a g e Tu r b i n e Fl o c c u l a t o r Pa d d l e Wheel Fl o c c u l a t o r Hy d r a u l i c Fl o c c u l a t o r Mix & Match Op t i o n Si n g l e So u r c e Ma n u f a c t u r e r MRI MRI MRI MRI

Optimizing G-values for each pretreatment stage is essential from extremely high in the rapid mix stage to extremely low in the hydraulic final stage. Only MRI s Flocculation Systems enable maximal outcomes through a choice of variable speed turbine, paddle, and hydraulic mixers, and the option of mixing flocculator styles. The result mechanical mixers can operate at higher speeds without impacting quiet zones in the sedimentation basin.

MRI Flocculation Systems utilize hydraulic mixing to reach new G-value lows in the final pre-sedimentation stage, which quiets turbulence and creates a buffer zone. Self-cleaning, the MRI hydraulic final stage is equipped with a patented hinged bottom plank* which allows a scraper mounted to the MRI Sludge Collector to travel into the final stage and remove incidental sediment. In addition, the hydraulic stage consumes zero energy, and is very low maintenance.

he new standard in flocculation: a systemiz Vertical turbine flocculators deliver wide variable ranges. MRI s vertical turbine flocculators offer high collision rates while using less energy. By producing an axial flow pattern, vertical turbines provide more efficient use of the flocculation area and prevent incidental settling. Each paddle has a unique drive allowing more versatility in mixer speeds and flow directions. Combined with a self-cleaning, low-g final hydraulic stage, as found exclusively in MRI Flocculation Systems, the vertical turbine flocculator is flexible and efficient. Drive Unit Each vertical turbine mixer comes with its own drive unit, which can be adjusted individually. Staging Baffles Ported or Serpentine MRI staging baffles provide maximum flexibility and hydraulic control. Tu r b i n e Axial, radial, or mixed flow impellers are available. Hi n g e d Bottom Plank Hy d r a u l i c Patented design opens to Final Stage allow automated cleaning by MRI s unique self-cleaning MRI Sludge Collector. hydraulic final stage flocculator allows low-g with minimal cleaning maintenance.
ed approach. Horizontal paddle wheel flocculators enable lower mixing speeds. MRI s horizontal paddle wheel flocculators consist of stainless steel shafts, structures and paddles. Typically, paddle wheels operate in the mid-g range with low rotating speeds. Since the paddles are large and move a great deal of water, the stages are completely mixed even at low speeds. Made of stainless steel rather than FRP, MRI blades avoid glass-shard contamination and the possible negative affects on downstream membrane filtration. Powered by stainless steel chain that enters directly into the mixing basin, through-wall seals are also avoided. Underwater bearings are waterlubricated, ultra-high molecular weight polyethylene for long-life and nearly zero maintenance. Greased Cooper sealed ball bearings can be provided. Inlet Diffuser Quick and easy to install, MRI s diffusers take the energy out of flow entering the sedimentation basin so floc particles settle faster. Drive Unit MRI s drive unit is provided with stainless steel chain to transmit power to the underwater shaft. Stainless Steel Paddles MRI s all stainless system avoids wood or FRP deterioration. Shaft Bearing MRI standard shaft bearings are water lubricated, UHMW polyethylene for years of nearly zero maintenance service.

Combining these elements with the patented, self-cleaning, low-g, hydraulic final stage flocculation and buffer zone between the flocculator and clarifier, MRI is the single source for a complete flocculation system. MRI s electronic control system tracks conditions and modulates flocculator rotational speeds and other variables, and can be monitored and controlled via the Internet. Fine-tune flocculation. Precisely engineered, only MRI Flocculation Systems enable flocculation outcomes to be fine-tuned for a significant increase in efficiency. By combining mechanical and hydraulic stage flocculation and leveraging maximum range G-values, MRI systems provide operational benefits, including: Hydraulic final stage allows more aggressive mixing in previous three mechanical stages. Typically, mechanical flocculators must operate at an rpm high enough to prevent solids from settling in the final flocculation stage. The MRI self-cleaning hydraulic final stage provides a low G-value. Settled solids are removed by an attached scraper mounted to the MRI Sludge Collector. MRI flocculators are available in vertical turbine, horizontal paddle wheel or all hydraulic (jet) mixers.
