Further, the energy savings enabled by Millad NX 8000 clarifier have been validated by UL[R] Environment, a wholly owned subsidiary of Underwriters Laboratories (UL) and an independent environmental claims validation company.
The existing secondary clarifier has a sidewater depth of 9 1/2 feet.
Mills using surface supplies often experience water quality excursions that the clarifier just cannot handle when the river "turns over" seasonally.
Irgaclear XT 386 also tolerates higher compounding and processing temperatures than many other clarifiers, and maintains its effectiveness even when subjected to multiple processing cycles, as if often the case when regrind or recycled resin is used, says Ciba.
The compact clarifier system can process up to 1001/b of fermentation solution and is supplied on a mobile frame ready to be connected to its required duty.
This study evaluated the possible use of porous sodium aluminosilicate (zeolite) as a wet end filler and as a white water clarifier in dissolved air flotation.
A sidestream of clean hot water from the clarifier is discharged at a rate of 45 gal/min to the sanitary sewer for control of dissolved solids in the water system.
