Outer-edge recesses trap fibrous material to clean the cylinder screen, cutting friction, wear, energy use, and maintenance.

Composite chain links with stepped pins and strain gauges cut corrosion, debris buildup, and maintenance in wastewater settling basins.

A vertical perforated rotor uses centrifugal force and pressure gradients to wash and dewater pulp at high output without massive press structures.

A servo-driven extrusion and striking assembly separates sewage from solids, prevents filter tank clogging, and reduces manual manure handling.

Nonionic compounds lower sulfide ore froth and underflow viscosity, easing clay-related settling and filtration bottlenecks in copper and molybdenum processing.

Porous biodegradable containers with absorbents separate FOG from water in grease traps, cutting sewer blockages and enabling biofuel transport.

A detachable top-access drive and movable ring layout improves maintenance visibility, speeds disassembly, and prevents sludge buildup.

A removable filter-aid precoat prevents cloth clogging and sticking in paint sludge presses, improving dewatering and cake removal.

Chemical sprayers and submersible pumps break up and extract sludge before filtration, improving water cleaning efficiency and reuse.

Reinforcement AI adjusts decanter settings from real-time cake dryness and centrate purity data to cut manual tuning time and disposal costs.

Multi-stage pretreatment aggregates nanoscale solids before cotton and ceramic filtration, cutting turbidity and membrane clogging.

Automated zeolite filtration and hot-air regeneration remove ammonium from slurry with low energy use while recovering nutrients.

A vinyl-amine and vinyl-sulfonic acid route produces high-purity sulfobetaine monomers while reducing toxic reagents, by-products, and water-control demands.

Fibers trapped in a helical-strip gap form a rotating brush that keeps separator screens open, reducing clogging and cleaning shutdowns.

Electroactive gelling, oxidation, and coagulation turn PFAS into removable hydroflocs, cutting energy use while treating long- and short-chain PFAS.

A spray-rinsed filter belt separates fibers and microplastics while preserving organic matter and microbiota through controlled cleaning and dewatering.

Anhydrous ammonia salts out dissolved potassium sulfate, enabling high-yield recovery from industrial streams with less energy than evaporation.

Ammonia addition precipitates sodium sulfate from industrial solutions at ambient conditions, cutting energy use while improving sulfate removal.

Targeted wall spraying cuts sludge friction and wall buildup in gravity hoppers while preserving dry matter content and preventing clogging.

Separate flotation and microfiltration loops purify two process water circuits for reuse or discharge while cutting water demand.

Repulping and washing geothermal filter cake removes chloride salts, raising manganese-zinc concentration for cleaner downstream recovery.

Using sludge ash as a renewed oxygen carrier helps delay carrier degradation in fluidized bed gasification while producing hydrogen-rich syngas.

Vacuum-assisted screw press dewatering improves filtration from inlet to outlet, avoiding entanglement and re-waterlogging while raising dry matter content.
