Advanced Technology and New Device

Electric Fenton method

Cathode electrolysis Fenton method

Sacrificial anode process

Ferric ion loop method

Fe3+ cycle method has a battery device for converting iron hydroxide precipitation into ferrous ions, which accelerates the conversion of Fe3+ to Fe2+ in the reaction process and improves the yield of OH in Fenton reactor.

DTRO dish tube reverse osmosis membrane

DTRO disc type reverse osmosis film main accessories are: DTRO diaphragm, diversion disk, pressure flange, fastening installation interface.

Advantages:

1. Resistance to pollution, high pressure, high COD, high TDS

2. Anti-pollution and anti-scaling

3. The membrane component is easy to clean and the performance parameters are well recovered

4. Wide range of application, stable water quality

5. Standardized, modular configuration, a single set of processing capacity up to 1-100m3 /h

6. Ultra-high pressure, ultra-high recovery rate

7. Membrane components are easy to maintain, can be replaced and reused separately

8. Simple pretreatment, suitable for SDI up to 15

Determination of COD in landfill leachate by ultraviolet spectrophotometry

The standard method of COD determination -- potassium dichromate method, this method is cumbersome to operate, time-consuming, electricity consumption, reagent consumption, and the use of highly toxic mercury sulfate, secondary pollution is serious. Therefore, to explore a rapid, energy-saving, reagent saving, less pollution, reliable results, and suitable for batch determination of COD water samples has become the goal of people's efforts. So we found the ULTRAVIOLET spectrophotometry
