When starting a centrifugal pump, should the pump or the valve be opened first?
The starting sequence and valve status of the water pump directly affect its safety and efficiency, and different pump types have different starting methods.
Water Treatment Process: Multi-media Filtration
Multi-media filtration is a key link in Water Treatment, and its core equipment is a multi-media filter. The process mainly includes two stages: filtration and backwashing, which will be explained separately below.
What Are the Reasons for the Decrease in Electrical Resistivity of EDI Equipment?
During the operation of EDI ultra-Pure Water equipment, if there is a decrease in water production resistivity, it is usually closely related to influent water quality, operation parameter control, pollutant accumulation, and other factors.
Back Pressure Fault and Detection of Water Production in Reverse Osmosis Operation
The PA layer forms a densely cross-linked network structure through the interfacial polymerization process, which is the core layer to realize the desalting function. Under normal working conditions, the inlet pressure should be maintained at 1.0-1.5MPa (depending on the water quality), and the water flow should permeate from the film surface to the production pipe.
Ultrafiltration System Dosing Point and Instrument Setting Principle
Raw water pretreatment pipeline system is usually equipped with a fungicide dosing device and temperature, turbidity detection instrument. The core function of fungicide is to effectively inhibit the proliferation of microorganisms and ensure the cleanliness of water pipelines and treatment devices.
