ADVANCED REACTIVE MEDIA SYSTEM

STATIC AND DYNAMIC LAB TESTING

INTRODUCTION 

To meet growing industry requirements for 

heavy metals removal, Siemens is developing a 

new Advanced Reactive Media System. The 

core of this proprietary treatment process is an 

iron containing media which is oxidized under 

carefully controlled conditions. The media acts 

as an electron generator to chemically reduce 

soluble metal cations and oxyanions to insoluble 

forms. During the reaction, the treated 

contaminants are removed by surface 

adsorption and chemical incorporation into iron 

oxidation products. 

As part of this technology development effort, 

Siemens has created static and dynamic 

laboratory tests to assist in determining the 

feasibility of the system for metals removal. 

STATIC TEST METHOD 

Purpose 

The static test determines if the Advanced Reactive 

Media System will be appropriate for the application 

on a “go / no go” basis for different contaminants of 

interest. A one to five gallon water sample is required 

for testing. Samples are shipped without the addition 

of any preservatives, which would alter the 

characteristics of the water and invalidate the tests. 

Procedure 

Upon receipt of the water sample, Siemens will 

complete an analysis of the as received water. The 

sample is analyzed for the contaminants of concern 

and other parameters needed for evaluation. 

Static Test Laboratory Apparatus 

If necessary the sample pH is adjusted to the optimal 

range determined for the test water. Multiple aliquots 

of the test water are then added to test containers 

containing a measured quantity of reactive media and 

other reagents. The containers are then sealed and 

placed on a rotary mixer. Sample containers are 

pulled off the mixer after predetermined mix times 

(e.g. 1, 2, 4, and 8 hours) based on the analyzed 

water quality. Samples removed from the mixer are 

filtered to remove the reactive media and quench the 

reaction. The filtrate is then analyzed and results 

evaluated. 

Results

The target contaminant concentrations are examined 

and additional samples run if necessary. When 

complete, the results are evaluated to determine 

whether the Advanced Reactive Media System is 

capable of removing the contaminants to the target 

Concentrations. If so, in most cases the dynamic test 

will be performed. If not, other technologies may be 

evaluated for the water sample.

which in actual case of use do not always apply as described or which may change as a result of further development

DYNAMIC TEST METHOD 

Purpose

The dynamic test determines the hydraulic retention 

time needed for the wastewater treatment parameters 

and provides a more definitive expectation of removal 

efficiency. The required water sample amount will 

vary between 55-300 gallons, based on results of the 

static test. 

Procedure 

Upon receipt of the water sample, Siemens will 

perform a water analysis to confirm that the sample is 

consistent with the samples used for the static test. 

The sample is analyzed for contaminants of concern 

and other parameters needed for the evaluation. 

Dynamic Test Laboratory Apparatus 

After completion of the initial water analysis, the 

reaction chamber is filled with the test water 

containing reactive media. The test water is pumped 

to the reaction tank (either a single tank or two in 

series as determined by earlier evaluation) at a 

controlled flow rate and effluent samples are 

analyzed for targeted parameters The test is 

repeated at various flow rates to evaluate to 

determine what operating conditions are needed to 

successfully remove the targeted contaminants. The 

goal is to determine the shortest hydraulic retention 

time required to meet the treatment requirements. 

Results

The results will be evaluated to determine whether 

the Siemens Advanced Reactive Media System is 

capable of removing targeted parameters at 

reasonable retention times. 

After an application has been successfully evaluated 

using the static and dynamic tests, the next step for 

evaluation is an on-site pilot test. Siemens has pilot 

reactors available for conducting on-site testing and 

can provide a proposal for a pilot test program.
