STRO
Advantages
1.Improvements to the water channel
1.1.An open inlet flow channel with excellent hydraulic characteristics
1.2.The width of the flow channel is expanded to the maximum series of flow channel width
1.3.The degree is more than 3 mm, while the ordinary roll film is less than 1 mm
1.4.Greatly optimizes the inlet channel and the effective surface of the membrane product
1.5.Alleviate the traditional roll membrane fouling defects.
2.Improvement of the rolling method
2.1Blade shortening, increase the number of blades.
2.2Shortens the length of fresh water channel and reduces the pressure loss of fresh water channel.
2.3The net pushing pressure of the membrane tends to be the same.
2.4Try to keep the water flux of different parts of the membrane equal.
2.5.Reduce concentration polarization
