An Alternative for "automatic waste water neutralization plants"

Automatic waste water neutralization plants:

Concentrated waste water streams can contain toxic substances, these waste water streams can not be drained away, they first have to be treated. An example is the regeneration stream for an ion exchanger. This regeneration stream or waste water has to go through an "automatic waste water neutralization plant". This plant detoxifies, neutralizes and dewaters the streams, in this plant the inorganical material is detoxified (removal of heavy metals) by oxidation, absorption or reduction and afterwards it is neutralized. The stream will be filtered and the solid particles will be collected and stored in a waste special dump where the are protected against rain and ground water. The filtrated water can, after control, be drained.

Disadvantages:

• The filter cake still contains toxic substances

• The filtered water can still contain toxic substances which have to be neutralized before draining.

An alternative:

An alternative for the removal of Cadmium, Cobalt, Copper, Gold, Iron, Lead, Manganese, Mercury, Molybdenum, Nickel, Palladium, Ruthenium, Silver, Tin and Zinc can be the Metallyse system. A system which uses the principle of electrolysis to collect the metal. After this process the "Automatic waste water neutralization plant" should not be necessary anymore.
In some cases the Infra Red evaporation unit is also a good alternative.
