System for filter analysis and regeneration

A system, comprising:

• a pipe including a fluid pathway;
• a filter along the fluid pathway of the pipe, the filter configured to, in operation, filter a fluid moving through the fluid pathway and passing through the filter;
• a sampling valve in fluid communication with the fluid pathway and located downstream from the filter, the sampling valve including an opened position and a closed position;
• and
• a reducing agent sampling system in fluid communication with the sampling valve, the reducing agent sampling system is configured to, in operation, receive the fluid when the sampling valve is in the opened position, convert materials dissolved in the fluid into insoluble particles within the fluid received by the reducing agent sampling system, and count the insoluble particles within the fluid after the dissolved particles are converted into insoluble particles.

A system, comprising:

• a storage tank containing a fluid;
• a circulation fluid pathway in fluid communication with the storage tank;
• a first filter along the circulation fluid pathway;
• a valve along the circulation fluid pathway and downstream from the first filter along the circulation fluid pathway;
• a workpiece tool fluid pathway in fluid communication with the valve;
• a second filter along the workpiece fluid pathway, the second filter configured to filter the fluid as the fluid passes through the second filter along the workpiece tool fluid pathway;
• a first particle counter along the workpiece tool fluid pathway and upstream from of the second filter, the first particle counter configured to, in operation, count particles within the fluid as the fluid passes along the workpiece tool fluid pathway;
• a second particle counter along the workpiece tool fluid pathway and downstream from the second filter, the second particle counter configured to, in operation, count the particles within the fluid as the fluid passes along the workpiece tool fluid pathway;
• a processor in electrical communication with the first particle counter and the second particle counter, the processor configured to, in operation, receive a first signal from the first particle counter and a second signal from the second particle counter;
• and
• a backwash valve along the workpiece tool fluid pathway, the backwash valve being between the filter and the second particle counter along the workpiece tool fluid pathway, the backwash valve configured to, in operation, perform a backwashing regeneration operation to backwash the second filter;
• and
• a backwash fluid source in fluid communication with the backwash valve, and
• wherein the backwash valve is positioned between the second filter and the second particle counter to prevent, in operation, a backwash fluid from traveling to the second particle counter.
