QWhat types of chemicals are used in RaeX systems?
ATypical chemicals include metal coagulants such as PAC or FeCl₃, and anionic/cationic polymer flocculants, selected through preliminary lab testing.
-
QWhat advantages does RaeX offer compared to traditional flocculation units?
A
RaeX uses high-efficiency mixing and automatic chemical control, reducing reagent consumption and improving water clarity.Its compact design minimizes footprint and simplifies maintenance.
-
QCan RaeX be integrated with other Deepflow systems?
A
Yes. RaeX is designed to operate in-line with Seltra (membrane) and Aevya (evaporation) units, forming the first stage of a full ZLD – Zero Liquid Discharge process.
-
QWhat is the typical treatment capacity of RaeX systems?
A
Standard versions handle 1 – 50 m³/h, customizable on request depending on solids concentration and effluent type.
-
QAre RaeX systems automatic or manual?
A
All RaeX models feature PLC automatic control with regulation of flow rate, pH, and chemical dosing.Semi-automatic versions are available for small-capacity plants.
-
QWhat main technologies are integrated in RaeX systems?
A
RaeX combines controlled chemical reaction, dynamic mixing, slow flocculation, and sedimentation or final filtration.Modules may include pH neutralization and automatic coagulant/flocculant dosing.
-
QIn which industries can RaeX systems be applied?
A
They are used in chemical, electroplating, electronics, food, pharmaceutical, metallurgical, and mixed industrial wastewater sectors.RaeX is ideal for streams containing metals, oils, paints, or emulsions.
-
QWhat are RaeX systems used for?
A
RaeX systems are designed for flocculation, coagulation, and sedimentation of suspended solids in industrial wastewater.They represent the first stage of clarification and organic load reduction before filtration or evaporation.
-
QCan one membrane module be replaced without stopping the plant?
A
Yes. Modular skids with isolation and bypass valves allow single-module maintenance while the rest of the system remains operational.
-
QHow to handle sudden flow or pressure shocks?
A
Seltra control systems modulate pump speed and bypass valves to smooth fluctuations. Avoid sudden feed shocks to prevent mechanical stress.
-
QWhen is deep chemical regeneration required?
A
When normal CIP fails to restore performance (flux, ΔP), a stronger chemical treatment (oxidative or special formulation) may be applied, observing compatibility limits.
-
QHow should spare membranes be stored?
A
Keep membranes sealed in original packaging, clean and shaded, between 5 °C and 30 °C.Wet membranes must be stored in a preservation solution containing biocide and buffer.
