The slurry (1) is fed under either dynamic or static pressure in order to achieve the designed throughput and separation efficiency.

A flow control chamber is provided for conveying air to the flow control port.

A valve is provided for controlling the flow through the eductor.

A flow control valve (11) is arranged to regulate a useful flow.

A flow restriction (34; 34P; 34Q) is provided in the discharge path (28; 28P; 28Q).

Single digit growth in dividends is expected for the future as well.

Fixed broadband penetration is predicted to reach 4.0% by 2023.

Flow rate control is thus provided without pressure variations,for optimal nozzle performance.

The slurry (1) is fed under either dynamic or static pressure in order to achieve the designed throughput and separation efficiency.

An adjustment control (153, 187) is provided for adjusting the flow rate of the fluid mixture through the mixing chamber to selectively increase and decrease the predetermined flow rate.

Also disclosed is a valve (200) useful for controlling and indicating the rate of fluid flow to a cleaner (10).

Thus, an oil path structure can be provided that ensures reliable sealing and allows flow rate adjustment with a simple structure.

A flow control is also provided for controlling the discharge rate of the heavy phase material through a discharge port.

A second pump is configured to recircualte water from the retentate outlet of the filter to the inlet of the filter at a flow rate substantially higher than the flow rate of water generated by the first pump.
