Multiple Effect Evaporation System Waste Water Treatment MVR Evaporator
MVR Description
The MVR evaporator is a new type of high-efficiency energy-saving evaporation equipment mainly used in the pharmaceutical industry. This equipment uses low-temperature and low-pressure steaming technology and clean energy to generate steam for energy. It separates the water in the medium and is an internationally advanced evaporation technology. It is an upgraded product that replaces the traditional evaporator.
In summary the adventages of MVR system are as follow
1.Energy saving: high thermal efficiency, energy saving, lower power consumption,the energy consumption is about 1/6To 1/5 of traditional evaporator. significantly reduc the operation cost
2.Environmental protection
3.Low operating costs: only the traditional evaporators One-third to half
4.Evaporating temperature is low, difficult to corrosion stainless steel equipment, difficult to scale, very suitalbe for heat-sensitive material
5.Automatic: The entire system realized automatic control from the filling, preheating, evaporation, cleaning, maintenance and other steps of the. Avoid human error, reduce the labor costs, improved product quality
6.Small footprint
7.Avoiding the purchase of boilers, chimney construction investment and maintenance costs
Operation cost comparison
The operation of the two evaporation processes for the treatment is shown in the table.

| MVR pre concentration | 5-effect evaporation station | |||
| Evaporation water (t/h) | 100 | 64.28 | 35.72 | |

| Water(t/h) | 900 | / | 350 | |
| Running cost | RMB/hour | 4500 | 960 | 1633 |
| RMB/T water evaporation capacity | 45 | 25.93 | ||
| RMBx10000/Day | 10.8 | 6.2 | ||
| RMBx10000/Year(340days) | 3672 | 2115 | ||
Note:In operation cost estimation:steam 150rmb/t,electricity 0.6 rmb/kWh,water 0.5rmb/t.
The investment of combined evaporation process equipment increased: evaporator (2500 m2) 375x10000 RMB; MVR compressor 400x10000rmb, total 775x10000 RMB
Annual operating cost reduction of combined evaporation process: 3672-2115 = 1557 (10000RMB)
Investment increase payback period of combined evaporation process: 755 ÷ 1557=0.5year
It can be seen that taking the scale of 100t / h as an example, the combined evaporation process can recover the increased investment in half a year, and save 1557 (10000 RMB) every year in the future, with considerable economic benefits.
The handling capacity can be up to 100T/h, with advantages such as small floor space, compact structure, stable operation and so on.
