QWhy is the evaporation temperature lower than normal?
APossible causes include insufficient liquid level, faulty temperature sensor, or excessive vacuum pressure. Verify sensors and adjust the working level in the main tank.
-
QWhat should I do if the evaporator fails to reach the nominal vacuum?
A
Check for leaks, inspect the vacuum pump, gaskets, and threaded joints. Clean the condenser and ensure there is no air leakage through drain or vent valves.
-
QHow can I request service or operator training for a running unit?
A
You can submit a request via the Support & Download section of the Deepflow website or email service@deepfloweco.com. A certified Deepflow technician will contact you within one working day.
-
QCan the evaporator be integrated with other Deepflow systems (e.g., Seltra or RaeX)?
A
Yes. All Aevya evaporators are designed to operate in line with ultrafiltration, reverse osmosis, and chemical-physical pretreatment systems, achieving complete ZLD (Zero Liquid Discharge) processes.
-
QWhat is the typical lifetime of an Aevya evaporator?
A
With proper maintenance, service life exceeds 10–15 years. Wear parts such as gaskets, pumps, and valves are easily replaceable with standard spare parts.
-
QHow should the plant be started after a long shutdown?
A
Run a vacuum cycle, check the refrigeration compressor, and gradually start the heating. Deepflow’s control system automatically guides the start-up sequence, monitoring key pressures and temperatures.
-
QWhat is the average energy consumption of a heat pump Aevya?
A
Depending on the model, size, and type of effluent, DEH and DE2H systems typically consume 25–250 kWh per ton of evaporated water.The PFET (DEP) model can go below 20 kWh/t, thanks to its high-efficiency polymer exchange technology.
-
QCan waste heat be used to power the evaporator?
A
Yes. The DES and DE2S models can be connected to hot water or residual steam lines, enabling energy recovery from existing industrial processes.
-
QWhat distillate purity can Aevya achieve?
A
The distillate generally reaches a conductivity below 20 µS/cm, often suitable for internal reuse or discharge in compliance with Chinese standard GB 8978.
In cases involving solvents, low-boiling compounds, or azeotropes, and when high purity is still required, the distillate can be further polished using Seltra membrane systems, directly integrated into the Deepflow line. -
QHow often should CIP cleaning be performed?
A
The frequency depends on the composition of the wastewater. Typically every 1–2 weeks for complex effluents or monthly for cleaner ones. PFET models greatly reduce CIP frequency thanks to their anti-scaling surface.
-
QWhat kind of regular maintenance do Aevya evaporators require?
A
Regular inspection of filters, gaskets, and the vacuum system is recommended. The main operations can be performed by plant personnel following the Deepflow manual and standard safety procedures.
-
QWhat is the difference between a heat pump evaporator and a steam evaporator?
A
A heat pump evaporator uses a refrigeration circuit to provide evaporation energy efficiently with reduced power consumption.A steam evaporator instead uses external steam or hot water, suitable for plants that already have an available thermal source.
