R3HAB.PRO GmbH
About
r-h-pro GmbH (branded R3HAB.PRO) is a German process engineering firm based in Haiterbach, Baden-Württemberg, specializing in the planning, construction, and operation of water treatment, surface pretreatment, cathodic dip coating (KTL), and wastewater treatment plants. The company holds ISO 9001 certification, TÜV Süd WHG qualification for constructing and repairing LAU and HBV facilities under the German Water Resources Act, and SCC safety certification. In water treatment, r-h-pro engineers demineralized water production systems using reverse osmosis and ion exchange, with pretreatment stages including flocculation, multi-layer filtration, activated carbon filtration, softening, chemical dosing, and ultrafiltration. Their surface pretreatment lines handle automated cleaning, degreasing, and zinc phosphating conversion coating with integrated oil separation, ultrafiltration, hydrocyclones, temperature control, and pH regulation. For KTL dip coating, they design full-surface cathodic electro-dip coating systems featuring anolyte systems, UF permeate rinsing, overflow weirs, continuous filtration, and ultrasonic or laser carrier cleaning. Their wastewater treatment capability covers oily, acidic/alkaline, heavy-metal-laden, and toxic organic wastewater via microfiltration, ultrafiltration, precipitation/flocculation, the Fenton oxidation process, sedimentation, filter press dewatering, selective ion exchange, and evaporation. r-h-pro also provides plant modernization, repair, and retrofit services for existing installations from any manufacturer.
Key Products
