This case study outlines a representative industrial wastewater scenario in which a manufacturing facility requires reliable solid-liquid separation from a complex, variable effluent. It illustrates alumina ceramic membrane selection and process design rather than a specific client project; no ...

EXECUTIVE SUMMARY Industrial wastewater containing oil, emulsions and high suspended solids rapidly fouls organic polymer membranes, forcing frequent cleaning and short membrane life. Asymmetric alpha-Al2O3 multichannel tubular ceramic membranes solve this at the material level: the hydrophilic ...

Meta Description Learn how alumina single-channel ceramic membranes with a symmetric structure were supplied for an electrochemical processing project in Eastern Europe, providing reliable filtration performance and excellent durability under demanding operating conditions. Project Background An ...

Background An NCM producer reported accelerated roller degradation near a specific temperature zone. Unexpectedly, the hottest section of the kiln showed relatively little damage. Findings The most severe corrosion occurred around 700–800°C. This region coincided with: Lithium vapor exposure Active ...
-
Background A customer compared two rollers operating in the same kiln. One roller had excellent straightness. The other showed slight deviation but remained within specification. Unexpectedly, the perfectly straight roller failed first. Initial Assumption The customer assumed that straightness alone ...
-
Background A customer operating a high-temperature roller kiln observed gradual roller sagging after approximately six months of continuous operation. No visible cracks were found, but product quality began to deteriorate. Symptoms Operators reported: Increased roller runout Uneven material ...
-
Background A battery material manufacturer reported an unusual problem: Over a period of eight months, multiple SSiC roller rods failed in nearly the same kiln location. The rollers came from different production batches and were installed at different times. Despite replacement with new rollers, ...
-
Background A customer observed unusual spiral wear patterns at the ends of several silicon carbide rollers. The kiln utilized a spring-supported roller system. The wear pattern raised concerns about possible shear failure. Observations The damaged rollers showed: Helical wear marks Localized debris ...
-
Background During kiln startup, a customer reported that four out of five SSiC rollers experienced end-face chipping. Surprisingly, one roller remained completely intact. The temperature was increased from room temperature to approximately 946°C over a 12-hour period. Initial Assumption The customer ...
