KEY STEPS OF THE LABORATORY TRIALS

STEP 1

Definition of customer requirements
Gathering of information

STEP 2

Test protocol proposal

STEP 3

Laboratory
And/or pilot tests

STEP 4

Capitalising on results: proposal for a finalised technical solution with presentation of report & questions/answers

RESULTS OF THE LABORATORY TRIALS

1. Determine the optimal filtration parameters according to your expectations and priorities (% of humidity, production rate, % of solids in filtrates, etc.).

Examples of parameters that can be defined for these tests:

/ Filter cake moisture content
/ Concentration of solids in filtrates
/ Process temperatures: paste, wash

/ Quantity of water used for washing: washing ratio
/ Chemical concentration of products in the filter cake or filtrates
/ Use of chemical agents: flocculants, surfactants

2. Obtain recommendations to define the industrial equipment that will guarantee your results from filtration experts and an ISO 9001-certified laboratory.
