Problems solved by technology

In engineering applications, the equipment required by the traditional treatment process has high cost, high energy consumption, low efficiency, and is easy to block. However, there are fewer types of equipment for cell wall breaking using high-voltage pulsed electric field technology. Therefore, new applications are developed according to actual needs. Sludge cell wall breaking treatment equipment with high-voltage pulsed electric field is still a key research direction in the future
