Aeration membrane bubble tube diffuser

Aeration membrane bubble tube diffuser

Diameter: Φ65  Length: 500—2000mm
Tube diffuser technical data

Tube diffuser design and installation

1,When the tube micro-porous aerator in application,in the bottom of the aeration tank, the tube diffusers on the intake manifold generally spaced 500-2000mm. Aerator and aerator about the general spacing of 500-1500mm; depending on the water concentration, gas supply and other process conditions.

2,The arrangement of tube diffusers is based on the air flow rate which can be calculated according to the length of the aeration tank and the size of the bottom intake manifold.

3,The bottom of the intake manifold to be apart from the tank shore main pipe, and install a valve. welding a flange bending by the pool wall 500-600mm from the bottom of the aeration tank , and coupled with rubber gaskets and screws.

4,Tube diffusers to install 150-250mm from the bottom.

5,Each intake pipe from the pool wall down connected to the bottom of the intake manifold, connect one or more.

6,The aeration tank bottom should be flat.

Demister/Mist eliminator

PP mist eliminator

Demister (mist eliminator) is mainly composed of corrugated leaves, plates, clamps and other fixtures. In the wet desulfurization, easy to produce particle size of 10 - 60 microns "fog " in the absorption tower operation process ," Fog "not only contains water, but also dissolves sulfuric acid, sulfate, sulfur dioxide and so on, also causes the fan, the heat exchanger and the flue of the tarnished and the serious corrosion, therefore, Fog requirements, the purified gas before leaving the absorption tower to be demist. Demister nozzle is one of the main components of the demisting system. The defogger nozzle is mainly made of high quality plastic with high wear resistance and long service life.

Demister 2

The demister is used to separate the droplets entrained in the gas in the tower so as to ensure the mass transfer efficiency, reduce the valuable material loss and improve the operation of the compressor behind the tower. Generally, demisters are arranged on the top of the tower. Can effectively remove the 3 - 5um droplets, if set up the tower demister, not only to ensure the mass transfer tray efficiency, but also can reduce the board spacing. Therefore, the demister is mainly used for gas-liquid separation. Also for the air filter for gas separation. In addition, the screen can also be used as a variety of instruments in the instrumentation industry buffer to prevent radio interference, such as electronic jammers.

Water treatment cubic mesh packing

Water treatment cubic mesh packing

Cubic mesh packing has the characteristics of spiral mesh, which can make waste water, air and biofilm full mixing contact exchange. Biofilm cannot only balance stayed on the spiral mesh but also can maintain good activity and its pore variability. In the process of waste water running, gas collide with each other and be cut into smaller bubble network, increasing the utilization of oxygen can reduce aeration, while biofilms have good metabolism does not stick together, so it has the characteristics of bubble cutting ability, larger space utilization , no dead zone , etc. It is the current performance indicators of sewage treatment best filler.


1. The cubic mesh packing material is PP, high temperature resistance, acid-resistance

2. Over-all structure, high porosity, high surface area

3. Hanging membrane fast and easily fall off

4. Water flow in three dimension, no blocking, no clump

5. Light weight, not deformed after long using

6. Can be used as cooling tower fill,good heat-transfer, balance the water distribution

Physical characteristics

According to different fiber density, the filler porosity is 95% to 98%, fiber diameter ? 0.8mm ~ ? 1.5mm, fiber density 0.9 ~ 0.92g / cm3. Bulk density with the shape and porosity vary, usually 9 ~ 20kg / m3. High compressive strength of packing, under water treatment conditions are generally not deformed, under the conditions of loading 400kg / m2 compression deformation of not more than 8%, and is elastic deformation. Adapt to the temperature range of 5 ? ~ 40 ?, if the temperature is below 0 ?, the filler becomes more brittle hardness, impact resistance is poor, you must add special additives, it is generally not used in frozen water treatment.

Cooling tower

According to Publisher, the Global Cooling Towers market is expected to grow from $2.27 billion in 2016 to reach $3.36 billion by 2023 with a CAGR of 5.7%. Growing demand for cooling towers from developing regions, technological improvements in cooling towers and increasing demand for HVACR deployments among various industries are propelling the market. However, water requirement in bulk quantities and slow growth of these towers in Europe and North America are hindering the market.

Hybrid towers segment dominated the cooling towers market with a highest market share due to optimal cooling and water conservation. On the other hand, the demand for fiber-reinforced plastic (FRP) is growing rapidly as this material is corrosion resistance, less cost compared to other materials and easy to install. Growing construction projects and rising focus on building energy management technologies are increasing the demand for HVAC cooling towers. These cooling towers are widely used in industrial applications to maintain temperatures in chillers.

Asia Pacific has acquired largest market share owing to the adoption of cooling towers in industrial sector. Demand for cooling towers is also growing in China with the emergence of new power plant projects and rapid industrialization.
