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 controllable variables are – Differential speed of centrifuge, torque

– Polymer dosing

Centrifuge depended items are max

massflow, sludge consistency

and volumetric flow to the centrifuge

MOFI Automated floc imaging device

Sludge is taken from the process line

into deairing container

From the container the sample is

diluted and pumped through cuvette of

imaging unit

Imaging unit consists of standard

machine vision camera and LED

lighting

The sample dilution, pumping, image

grabbing and cuvette flushing is

controlled by PC software and control

electronics

Floc images are then analyzed and

several morphological features, such

as floc diameter, area aspect ratio, are

calculated in floc analysis

Reliable measurements -> Control, Optimization –> performance increase and savings
