Scope of application of low-temperature evaporator

The low-temperature evaporator relies on vacuum negative pressure and evaporates at 35-45 ℃. It focuses on small and medium flow rates, high salt/high COD, reduction of difficult to biodegrade waste liquid, reduction of hazardous waste, and concentration of thermosensitive materials. It does not require boiler steam and is suitable for factories without steam heat sources.

✅  1、 Mechanical processing industry

CNC cutting fluid, emulsion wastewater, grinding and cleaning wastewater, mold release agent wastewater

Characteristics: Oil content, high COD, foaming, difficult to biodegrade; Low temperature evaporation significantly reduces capacity, condensate can be reused, and concentrated liquid can be disposed of as hazardous waste

✅  2、 Electroplating/Surface Treatment Industry

Electroplating cleaning wastewater, anodizing, passivation, and polishing waste liquid; Wastewater containing heavy metals such as nickel, copper, and chromium

Features: Low temperature does not damage heavy metal complexes, heavy metals remain in the concentrated solution, condensed water can be reused for production, significantly reducing the amount of hazardous waste

✅  3、 Chemical and Fine Chemicals

High salt mother liquor, reaction residue, RO membrane concentrate, high COD organic waste liquid; Recovery of organic solvents such as ethanol and acetone

Suitable for thermal sensitive materials, avoiding side reactions caused by high temperatures, and reducing the risk of VOCs volatilization through sealed negative pressure

✅  4、 New energy, photovoltaics, semiconductor electronics

Lithium/cobalt containing wastewater from lithium batteries, high salt wastewater from cleaning photovoltaic silicon wafers, photoresist waste liquid, fluorine-containing cleaning wastewater

The condensate water has high purity and can be reused in the workshop cleaning process

✅  5、 Medicine, Biology, and Traditional Chinese Medicine Extraction

Concentrate traditional Chinese medicine extract, fermentation broth, and protein based biological medicine solutions

Low temperature protection of thermosensitive active ingredients to prevent high-temperature decomposition and damage of effective substances

✅  6、 Environmentally friendly solid waste leachate

Garbage leachate DTRO membrane concentrate, sludge pressure filtration high salt filtrate

Complex composition, high salt and high COD, difficult to degrade in biochemistry, suitable for reduced disposal

✅  7、 Food and daily chemical products

Fruit and vegetable juice, plant extract, honey concentrate; High concentration cleaning mother liquor for daily chemical products

Preserve flavor and nutrients, avoid high-temperature deterioration

✅  8、 Laboratory, small production line

Various mixed high concentration waste liquids in scientific research laboratories, sporadic hazardous waste liquids in small factories, and small pry mounted models suitable for small water volumes

❌  Not applicable scenario (choose to avoid pitfalls)

A large amount of volatile, low boiling point strong solvent waste liquid (which will penetrate the condensation system)

Continuous production of super large water volume (priority MVR)

Containing a large amount of strong corrosion and no suitable material (material evaluation needs to be done in advance for 316L/titanium material)

Extremely prone to boiling and a large amount of light floating oil, requiring pre-treatment at the front end, otherwise it will contaminate the condensate water due to material leakage
