Project Highlights

Nitrocellulose filtration in wastewater treatment requires equipment that can handle fine, hydrophobic, and flammable solids safely and reliably. Conventional filter technologies frequently fall short on all three counts, making closed, automated pressure filtration the preferred approach for this application. How does nitrocellulose create challenges for conventional wastewater filtration? Nitrocellulose particles are extremely fine and hydrophobic, […]

What filtration challenges arise in hot-dip galvanizing alkali circuits? In cold-rolling hot-dip galvanizing operations, process alkaline solution is continuously exposed to iron particles, oil, and sludge generated during strip cleaning and surface preparation. Left untreated, these contaminants degrade coating quality and prevent the alkaline circuit from being recirculated in a zero-discharge system. Magnetic rod adsorption […]

How does candle filtration support reliable solid-liquid separation in adipic acid processes? Adipic acid production places high demands on solid-liquid separation, particularly when processing high-solids slurries in nitric acid environments. Filtration equipment must combine corrosion resistance, stable performance, and controlled solids handling to support continuous operation and consistent product quality. What are the solid-liquid separation […]

How does candle filtration support rare earth and critical mineral processing? DrM Group has successfully delivered a FUNDABAC® candle filter for a customer in Australia, designed for use in a rare earth processing application. Rare earth and critical mineral production place high demands on solid-liquid separation, particularly where fine particles, variable feed conditions, and stringent […]

How does candle filtration protect membranes in chlor-alkali brine polishing? DrM Group has successfully delivered two FUNDABAC® candle filters to a client in Egypt for use in chlor-alkali brine polishing. In modern membrane-based chlor-alkali processes, electrolyser membranes are highly sensitive to suspended solids. Even low levels of particulate contamination can negatively impact cell performance, membrane […]

How can solid-liquid separation improve wastewater handling in oxy-hydrochlorination processes? Oxy-hydrochlorination (OHC) is a key process step in the production of ethylene dichloride (EDC), an essential intermediate in polyvinyl chloride manufacturing. In this process, ethylene reacts with hydrogen chloride and oxygen over a copper-based catalyst to form EDC, enabling efficient chlorine utilisation within integrated vinyls […]

How can low-shear mixing support reliable insulin production at industrial scale? DrM Group has successfully delivered a turnkey skid-mounted plant featuring FUNDAMIX® mixing technology for a pharmaceutical customer in Pakistan. The system is designed for insulin production, where gentle handling, hygienic design, and process reliability are critical to product quality and operational performance. What were […]

How does solid-liquid separation support solvent stability in direct air capture systems? Direct Air Capture (DAC) technologies remove carbon dioxide directly from ambient air, typically using amine-based solvents that selectively bind CO₂. Maintaining solvent purity and stability is critical to ensure continuous operation, predictable performance, and acceptable energy efficiency over extended operating periods. During DAC […]

Rich MEG Filtration in Action DrM recently delivered a custom-engineered rich MEG filtration system for a major oil and gas operator in South East Asia. The process package is built around two FUNDABAC® candle filters, specifically designed for the treatment of Mono Ethylene Glycol (MEG) used in offshore production and hydrate control. In subsea and topside operations, MEG plays a critical role […]

How does activated carbon filtration remove methanol and heavy metals from wastewater? DrM Shanghai recently delivered four FUNDABAC® filter systems for activated carbon to a Chinese client for the removal of methanol in a wastewater stream. In the process our filter in conjunction with activated carbon makes use of the ability to adsorb certain substances at a […]

DrM was asked by a major European PVC producer to help develop a treatment of VCM waste water stream in PVC production. Biodegradability Difficulty of PVC With a production capacity of 56 Mio. tpa, Vinyl Chloride (VCM) is one of the 20 largest petrochemical compounds in the world and is mainly used to produce PVC. […]

How will CONTIBAC® process and guard filters support lithium hydroxide production at Kwinana? Kuala Lumpur, Malaysia. DrM, Dr Mueller AG has signed a contract for the supply of specialised filtration equipment for Tianqi Lithium Australia’s newest lithium hydroxide processing plant, which will be located in Kwinana, Western Australia. Tianqi Lithium, which controls a majority stake […]
