1).Principle of STRO

The STRO membrane combined the design advantages of both Spiral wound and Open Channel. With a narrow and fully open channel, the STRO membrane overcomes the disadvantages of other common reverse osmosis membrane components and greatly optimizes the hydrodynamic performance. To a large extent, the common contamination and scaling problems in other reverse osmosis membrane components are reduced

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: 715.79 yuan

Outsourcing cost of concentrated liquid: 20T*4000 yuan /T= 80,000 yuan

Comprehensive treatment cost: 715.79 yuan + 80,000 yuan = 90,000 yuan/year
