Glass Grinding Swarf. It is very important for glass fabricators to have an effective glass grinding swarf filtration and separation system. Glass grinding swarf can wreak havoc on glass fabrication equipment, causing increased maintenance costs, unplanned downtime, decreased production, and decreased equipment life.
This method effectively separates sediments only from the sludge. No real oil recovery occurs, only the creation of an unstable oil phase which will precipitate again once pumped into another tank. • In crude oil washing, crude oil is used as a ‘solvent’ for sludge.

CentraSep Technologies offers an oil field sewage filtration and separation system that removes the solids from the oil field sewage. The solids from oil field sewage are removed in a dry cake form that automatically discharges into a container, drum or tote. The filtered solids are considered a Class “B” sludge for disposal.
A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B1) as material for production of steel.
It is particularly suited for the compaction of grinding sludge. EVTM-45-L is provided with a suction device which allows to recover the oil ejected during compaction phase, obtaining the lowest possible percentage of residual oil in the final briquette.
Oil sludge is a mixture consisting of oil, water and solids. The treatment on oil sludge would recover much oil and water for reuse. Also it is an ideal solution to for the solids disposal.
Grinding sludge is quite heavy and needs to be recovered. The industrial vacuum cleaner is the right tool to use, the best choice is surely a threephase wet and dry vacuum cleaner, which is powerful and ensures excellent airflow and vacuum performances.
