1.) Principles of DTRO

This technology is specially developed for the treatment of concentrated wastewater. Its membrane component structure is completely different from that of the traditional coil membrane. The flow channel of the stock liquid: The saucer-tube membrane assembly has a patented flow channel design form, using an open flow channel, the material liquid through the entrance into the pressure vessel, flow from the channel between the guide plate and the shell to the other end of the assembly, at the other end of the flange, the material liquid through 8 channels into the guide plate, the treated liquid with the shortest distance quickly flow through the filter membrane, and then 180º reverse to the other membrane surface. Then it flows into the next guide plate from the notch in the center of the guide plate, so as to form a double "S" shaped route from the circumference of the guide plate to the center of the circle, and then to the circumference, and then to the center of the circle on the membrane surface. The concentrated liquid finally flows out from the flange of the feed end

2.) Process - Characteristics

1. Strong process stability, simple maintenance, low energy consumption.

2. The process is simple and compact, and the complete sets of equipment are standardized.

3.The effluent water quality is good.

4. Flexible operation.

5. Short construction cycle, debugging, quick start.

6. High degree of automation, simple operation.

7. Small footprint.

8. Recyclable.

3.) Benefit analysis

1. Traditional waste liquid disposal

Outsourcing fee: 2500 yuan /T

100T/ year *2500 yuan /T= 250,000 yuan/year

2. After investing in wastewater treatment equipment

Equipment operation cost: 815.79 yuan

Outsourcing cost of concentrated liquid: 30T*4000 yuan /T= 120,000 yuan

Comprehensive treatment cost: 815.79 yuan + 120,000 yuan = 125,000 yuan/year
