Valmet TS measures the time of flight of a microwave signal in the sludge

Microwave’s delay time in water vs. total solids has a linear relationship

Valmet LS – flow path

17.09.2015

After sample valve (1) the sample flows to dearation vessel (2) where it is deaerated and any debris is screened out. The sample is then pumped (3) to the optical unit and measured (4). Finally the sample flows to the laboratory sampling point (5).

The unit has an automatic weak acid cleaning cycle, with programmable interval timing, that backflushes the unit to clean the optics (6).

All parameters can be set and the results monitored with a local user interface (7).

Constant and continuous sample flow by using the centrifugal pump

Sample is deaerated and contaminants screened before entering the measurement cell

Automatic cleaning – Always includes: measurement cell,

sample lines and screens are cleaned automatically, at configurable intervals based on real cleaning need.

– Automatic cleaning chemical addition (low concentration acid) at configurable intervals, independent of normal cleaning/flushing

Advanced self diagnostic– No measurement drift - light sources

inside the measurement cell are re-calibrated using the clean flushing water

– Diagnostics alert if dirt accumulating in measurement cell begins to affect TSS measurement

Two LED light sources measure absorption / scattering / depolarization as light passes through the centrate – critical for accurate TSS!

Sludge dewatering control application

Centrifuge: Removes solids from water by way of centrifugal force. The Dry Cake target value varies but usually cake solids are in the 12–

35% range. It is important that the Dry Cake TS % is as high as possible in order the transport costs and incineration costs are optimized

Reject water / Centrate TSS needs to be minimized in order the material is not circulating inside the plant and cause polymer and dewatering costs .

The centrifuge controllablevariables are – Differential speed of centrifuge, torque – Polymer dosing

Centrifuge depended items are max massflow, sludge consistency and volumetric flow to the centrifuge
