Fertilizer and Pesticide
Wastewater Source
The main source of the wastewater in the pesticide industry is from the process of pesticide production.
Same as other traditional industries, the typical characteristics of the wastewater are:
- High COD
- High salinity
- High chroma
- Complex composition
- Non-degradability
What Sanfeng offers
With rich industry experience and mature process technology, Sanfeng offers the complete solution to treat the pesticide industry effluent.
Solution:
- Pretreatment
- Stripper
- Evaporation Technology (MVR or MEE)
The system includes a stripping unit and an MVR evaporator unit.
- Stripping unit includes stripping tower and condenser.
- MVR evaporation unit includes preheater, evaporator, MVR compressor, and heat exchanger.
Technical Process of the system
System integated with MEE Evaporation and Pretreatment
Hardness removal of the pretreatment
System integated with MVR Evaporation and Stripper
COD include volatile matters and non-volatile matters.
With stripping tower, the volatile COD is removed from the top of the stripping tower under the effect of steam removal and collected by the condenser.
With MVR evaporation system, the non-volatile COD can be conconcentrated, and the brine salt can be crystal out.
Features & Advantages Of The System
The effluent contains High COD, like the wastewater from Pesticide plant, Pharmacutical plant, etc. MEE is mostly used to reduce the wastewater volume for standard discharge.
- It has the advantages of high efficiency and energy saving
- Short process flow, simple operation, stable operation, can be equipped with automatic online cleaning device.
- Fully automatic control system can realize the smooth operation of the system and reduce the failure rate caused by improper operation.
- It is convenient for management and operation. After the treatment of this system, the COD of wastewater can be greatly reduced to facilitate subsequent treatment.
