DEM140-50s Membrane Bioreactor Replaces TORAY Toray TMR140 Series Flat Membrane MBR

Product Description:

The DEM Membrane Bioreactor (MBR) process is a process that combines biological treatment with membrane filtration.
Degradable pollutants are degraded by bacteria and microorganisms, and after such biological treatment, the water in the activated sludge is separated by the filtration action of Toray membranes.

DEM140-50S flat membrane characteristics
Highly resistant to contamination
Compared to hollow fiber membranes, flat plate membranes have superior contamination resistance.

Simpler system configuration and operation
Flat plate membranes operate stably for long periods without the need for a backwash system.

Easy Maintenance
Flat membranes are designed for easy maintenance and cost savings.

Technical Parameters:

Chemical Cleaning of Membrane Elements:
(1) The chemicals used for cleaning may contain substances that may cause harm if they come into contact with the human body. When using chemicals, be sure to wear protective equipment such as eyeglasses and gloves with extreme caution. Be sure to check the contents of the MSDS.
(2) If the chemical comes into contact with skin or clothing, rinse immediately with plenty of water.
(3) If the chemical gets into your eyes, immediately flush with plenty of water and seek medical attention.
(4) When performing chemical cleaning, stop the cleaning operation as soon as you notice any abnormalities.
(5) Do not use a dosing pump to inject chemicals directly into the membrane element, as this may cause damage to the membrane element due to internal pressure rise. The agent must be injected by gravity or at a pressure of 10kPa or less.
(6) When using a dosing pump, make sure that the membrane module is completely submerged in water and that the distance between the liquid level and the top of the membrane module is more than 500mm.
(7) Chemicals should be kept in a cool place, avoiding direct sunlight.
(8) To avoid corrosion, please choose storage tanks made of appropriate materials to hold the chemicals according to the nature of different chemicals.
(9) Sodium hypochlorite should not be mixed with heavy metals or acids. Please pay special attention to the fact that when it is mixed with acid, toxic chlorine gas will be produced.
(10) Do not mix oxalic or citric acid with sodium hypochlorite. They produce toxic chlorine gas when mixed.
(11) Please stop aeration flushing during chemical cleaning, otherwise the membrane element may be damaged.
