More than 5000 Machines delivered worldwide
Meri has delivered more than 5000 Machines in hundreds of Sub Systems worldwide to the leading Paper Industry since 1990. 30 years of experiences and a portfolio of unique technologies and performance engineering have set meri to be considered as Paper Industry´s No. 1 Supplier for Environmental Technologies and Sustainability.
Waste Paper is today preferred Production Raw Material – but?
Consciously increasing request for Board and Packaging Materials and increased Paper Recycling Rates have made Recycled Paper the No. 1 raw material. But increased contamination and reject rates are an environmental and economiccChallenge for the mills operation. Meri has the Key- Reject Handling Technologies to reduce landfill or turn rejects and residuals e.g. into valuable fuel (RDF) for incineration or upcycled raw materials. Meri Reject Solutions are your gain in profitability and environmental image.
Hidden Champion – COMPAX the world´s most successful Reject Screw Press
Long before it was a Paper Industry´s topic meri has put high efforts in the development of “The COMPAX High Performance Reject Screw Press”. Today hundreds of successful running COMPAX dewater Millions of tons of Reject a year and secure enormous economical savings by reaching 70% plus Dryness*. Superior Mechanics as the custom high torque, gearbox, screw and screen design in combination with advanced wear materials and intelligent Counter-Flap, Torque and RPM Control have made the COMPAX No.1 for the Paper Industry.
*considers Bone Dryness, depending on fiber content
The best Reject Shredding Solution is – to go slow!
Modern Board and Packaging Paper Mills have to deal with hundreds of tons of “Light Weight Pulping Rejects” a day. The Shredding of these Rejects often-in combination with “Ropes & Bears” is a technological challenge. Shredder KPI´s are Availability and Wear- / Maintenance cost. The LION Shredders provide superior results, with independent hydraulically driven super slow rotating knives, and ISC (Intelligent Shredder Control) which continuously adapts Torque and Rotation to the Cutting Demands. The LION Shredder-Knives manufactured in a hot forge process and ISC Control have proved Continuous Shredder Operation up to 8.000 hours and more. LION Shredders are leading for Reject Applications.
Bio Kidney & Lime Trap – bring Your Specific Water Consumption to Target
Meri has set new milestones for the Paper Industry´s Sustainability.
ANAEROBIC Biological Water Clarification in combination with the Lime Trap Technology allows the Partial- / (Full**-) Recirculation of Clarified Effluent Waters back to the Production Process and so with significant reduction of the Mills’ Specific Water Consumption, and generation of valuable amounts of Bio Gas. The unique patented multi stage “Bio Kidney Process” can be used for Upgrades** or new Green Field Paper Mill installations. Meri provides the own successful R2S ANAEROBIC Reactors, in combination with a multistage Lime Tarp Process and special purpose designed
Effluent Treatment: meri has the best and most complete ETP- Portfolio for Paper Industry out of one hand
Effluent Treatment should be integrated with Water Loop Management and starts therefore already in Production Process. Depending on the type of paper production process, the individual permits and related costs for “Waste Water Discharge”, the ETP Process must be individually designed and optimized. Meri can offer all Chemical Physical- (Filtration, Sedimentation, Flotation) and Biological- (Anaerobic, Aerobic,SQB) Process Solutions as well as the Pre- and De-Watering Solutions for Residuals as Primary or biological Sludge. meri Technologies have numerous references in Paper Industry and can be delivered out of one hand.
Only Dry Residuals are Good Residuals – The meri De-Watering Portfolio
The Paper Production Process discharges in average 10% of the Raw Material Intake as “Solid Residuals” e.g. Fiber Rejects, Filtrate-, Primary- and Biological Sludge, Rejects etc.
meri offers the right Equipment for Pre-Dewatering and Pressing for all different Types and Quantities of Residuals which appear in single or multiple discharge points. The Pre De-Watering machines ELEPHANT Filter and BLUEDRAIN and the Screw Presses (RSP, COMPAX, MiniPress) are available in many different sizes and designs and lead the Paper Industry Applications with hundreds of References in Upgrade- and Green Field Projects.
Handling valuable Raw Materials gets more and more important
The Handling of thousands of tons of waste paper is precondition for any paper production.
We have decades of experience in handling waste paper and offer solid reliable solutions. Individual 3D- Designed Slat Conveyors, mobile and stationary Bale De- Wiring Units for flat or inclined conveyors, Fully Automatic De-Wiring Machines and related logistic control systems.
Why lose time with interfaces?
Take it out of one hand!
Meri has developed for more than 25 Years all Peripheral Subsystems around the Paper Production Process. WSR (Water, Sludge, Reject) Subsystems as well as the “Integrated Recycled Paper Mill Concept” have set new Standardsin Environmental Sustainability. Meri as a sole supplier can supply all Technologies as Material Handling, Fresh Water-Prep, Internal Water Management, Effluent Treatment, Reject and Residual Handling, Waste 2 Energy & more Out of on Hand with own proven Equipment.
Take care of your Paper Mill´s Health – Water Loop Management
25 and more Years ago fiber recovery and Save All applications have been purpose of water Treatment. Today advanced Water loop Management is not only key to “Lower Specific Water Consumption” but as well key for performance improvements as “Reduction of Stickies and Contaminants”, saving of chemicals and retention aids, ash and fines control, lower energy consumption and better run ability of the PM.
Water Loop Management follows technological principals but is always individual for each Paper Mill, we support You on your way to best Water Loop Management – Improve Your Sustainability.
The Difference:
Environmental Engineering by experts who understand the whole Paper Production Process
Process-, Production- and Environmental-Upgrades require a profound “Over All Paper Production Process Know How”. The meri Engineering Teams offer unique expertise, which goes beyond the interface and considers the production and peripheral processes as integrated mill. This allows us to elaborate for Your Mill integrated Process Upgrades, which secure synergies and gain in Productivity, better Environmental Interfaces, Improvement of Sustainability with Solutions and Equipment which was developed for the paper Industry.
