Task
As an internationally active company MÖLLER Medical has stood for innovation, quality and advanced solutions in medical technology, diagnostics and pharmaceuticals since it was founded in 1949. The medium-sized company has been part of the Centrotec Group since 2003 and continues to drive forward the development of state-of-the-art technologies.
MÖLLER Medical is one of the few medium-sized companies to offer the entire medical technology value chain from a single source. From development and design to precise machining processes such as turning, milling and grinding through to final assembly - all processes are carried out in-house to ensure the highest quality standards. Manufactured in Fulda, the products range from the finest cannulas to complex end devices that are sold worldwide.
The versatile portfolio comprises various business areas and product brands, including aesthetic surgery(Liposat, Vibrasat), CSF management(LiquoGuard), blood transfusion(Docon) and radiology(Biopsie, BiopC).
ALMAWATECH was commissioned to develop a waste water treatment plant to treat the acidic and metal-containing waste water from the electroplating baths, the mass finishing systems and the electropolishing.
Design data
Preparation quantity:
- 10 - 12m3/d
Target parameters:
- Annex 40 of the AbwV
Special feature:
- The wastewater treatment system was designed as a double-storey container construction.
- A Cr6+ chromate reduction was added.
Solution & implementation
Our holistic approach to the treatment of acidic and metal-containing wastewater from electroplating baths, mass finishing systems and electropolishing consists of several key steps:
- Homogenization in stacking tanksThe wastewater is first fed into stacking tanks, where it is thoroughly homogenized to ensure a consistent consistency.
- Precipitation and neutralization: In the next step, the wastewater is treated in the precipitation reactor using our equipment from the ALMA AQUA product series. Redox-controlled dosing of ALMA Treat DKS is possible for chromate reduction.
- Flocculation and sedimentation: Flocculants are then added to bind the precipitated particulate matter into larger sludge flocs. These are separated from the treated wastewater in the sedimentation reactor.
- Dewatering using a chamber filter press: The resulting sludge and the separated impurities are dewatered in a chamber filter press (ALMA CFP), which leads to considerable reductions in disposal costs.
- Final cleaning by gravel filter: Finally, the treated wastewater is passed through a gravel filter (ALMA FIL) to remove the remaining sludge flocs.
- Finishing stage: In addition, activated carbon filtration (ALMA FIL AK) and an ion exchanger (ALMA ION) were installed as a finishing stage to adsorb the last dissolved pollutants. Ion exchange regeneration is carried out automatically by our control technology.
The entire plant technology was installed in two XXL ALMA modules, which are built on two levels. The upper technical room container is accessible via a staircase, while the lower container module houses the sludge and operating equipment to ensure easy accessibility.
