First, calculate the daily/hourly processing water volume

Determine based on the actual amount of wastewater generated, such as 0.5t, 1t, 3t, 5t, 10t per day, directly corresponding to the tonnage of equipment treatment. It is better to have a slightly larger capacity than a smaller one to avoid insufficient capacity for later expansion.

Check the composition and concentration of wastewater

High salt, high COD, oil, and emulsion content: difficult to evaporate, requiring amplification of 10% to 30% of the remaining amount

Easy to scale and crystallize materials: It is recommended to choose a forced circulation low-temperature evaporator

Ordinary cleaning wastewater: optional falling film/immersion type, higher cost-effectiveness

Select the model based on the heat source conditions

Steam/waste heat: Choose heat pump+waste heat combination for the lowest operating cost

Only electric: choose fully electrically controlled heat pump low-temperature evaporator

Small site, requiring mobility: Choose integrated pry and install or small mobile type

Match the configuration according to the water outlet requirements

Only reduce: basic models are sufficient

Requirement for condensate reuse/standard discharge: requires precision filtration+defoaming+automatic cleaning

Combining site size and installation conditions

Choose a compact vertical model for the small car compartment, and a multi unit horizontal unit can be installed in the large car compartment, while reserving space for maintenance and piping.

Consider automation and operational costs

Unmanned: Choose PLC fully automatic, automatic slag discharge, and automatic cleaning models

Adequate manual labor: optional manual/semi-automatic to reduce procurement costs

Balance between budget and long-term operating costs

Limited budget: Select small tonnage standard models

Large water volume, long-term use: Priority is given to heat pump models with high energy efficiency, energy-saving and consumable saving, and the later savings far exceed the price difference
