I’m seeking advice from experts: are there any good methods for treating MVR concentrate at the moment?

Zero discharge of factory wastewater, but the concentrated liquid is difficult to treat; I’m seeking help from experts!
Designed specifically for concentrated solutions with high COD and high salt levels; the use of mother liquor is not recommended, as it tends to cause scaling and reduce evaporation efficiency. New technologies, new processes. The mother liquor at the rear end of the three-effect evaporator can be directly evaporated by a dryer, turning the liquid into a solid in just one step.
Use a non-standard drum mother liquor evaporation and drying integrated machine
Spray drying can be considered; the temperature used in spray drying is higher than that in triple-effect evaporation, and the heat sensitivity of the material needs to be taken into account
