Raven Activated Sludge Process Centrifuge

RAVEN F-10300 ACTIVATED SLUDGE PROCESS CENTRIFUGE - Solids % Volume in Just 15 Minutes

Wastewater treatment plants have several sample points in the process that indicate whether or not flow rates for wasting or returning activated sludge are appropriate. Tracking the percent of solids in a given sample provides operators with proactive information for activated sludge process adjustments.

The Raven Laboratory Centrifuge with Raven Centrifuge Tubes will provide quick, reliable concentration indications of mixed liquors from aeration basins, clarifier return sludge, and waste sludge removed from activated sludge systems. The Raven centrifuge tubes will indicate the suspended solids concentration in percent volume. 

Typical ranges for samples are:
1. Mixed Liquor: 1-5%
2. Return and Waste Sludge
a. Young (bulking): <10%
b. Normal: 10-20%
c. Old (denitrifying): >20%

F-10300 Centrifuge
Six-position rotor with 19mm Centrifuge Tubes rotates at a right angle to the axis of spin and provides a sharp, easily read solids/liquid interface. Digital timer (with fifteen minute speed key) to start and automatically switch unit OFF at end of test.
Corrosion resistant stainless steel and aluminum construction for durability and easy cleaning.
1/8 HP, 3000 RPM, Totally Enclosed Fan-Cooled motor designed for use in dirty environments.
On/Off switch in rear of unit near power cord.

B-10101-19 Centrifuge Tubes (19mm)
Clear, impact resistant polycarbonate plastic eliminates costly breakage and will not cloud. Not for use with flammables, solvents or cooking oils. Steep tapered conical design for volumetric determination of settleable solids (similar to Imhoff® Cones) that provide accurate measurements at low concentrations, such as those normally encountered with mixed liquor, return or waste sludge samples. Bright white markings, which contrast vividly with most sludge samples.
