Reverse osmosis membrane separation technology (RO Technology for short) is a new and practical water treatment technology. For a specific reverse osmosis system, the long-term stability of its performance is indispensable. The success of long-term performance of reverse osmosis system depends on no...

After the membrane system operates for a period of time, sometimes the processing capacity decreases significantly and can not reach the design capacity. The reasons for this phenomenon are mainly related to the working environment of membrane system, type selection and design, installation and cons...

1、 MBR membrane fouling judgment On line maintenance and cleaning: it has nothing to do with the pressure difference. Stop filtering regularly (about once a week) and drive the low concentration (300 ~ 500mg / L) solution into the membrane for cleaning. Online enhanced washing: monitor and manage...

Working principle of manganese and iron removal by manganese sand There are many methods to remove iron and manganese. Generally, the principle of oxidative removal of iron and manganese is adopted. It is the most economical and effective treatment method at present. Many equipment use natural mang...

Can't the water pump start? Insufficient flow? Can't suck water? Vibration, noise, motor failure... What should I do? The water pump cannot be started Common causes: the packing is too tight or the impeller and pump body are blocked by sundries; The pump shaft, bearing and leakage reducing...

The high / low pressure protection of water treatment reverse osmosis equipment is to prevent the RO high-pressure pump from idling or working under the limit high / low pressure. High voltage switch is used for high voltage protection. With the increase of equipment service time, the membrane will...
