Photovoltaic energy

In recent years, China's photovoltaic industry has developed rapidly. And photovoltaic wastewater treatment has received increasing attention. The main pollutants generated by the photovoltaic industry are high-concentration F- and NO3--N. High-concentration nitrogen-containing wastewater has always been a difficult problem in water treatment. If the wastewater is not treated properly, it will cause serious pollution and even unnecessary damage. Therefore, the treatment of wastewater is very important. AMKS is committed to helping companies achieve environmental standards, lower operating costs and more stable operation.
