HW-UP SERIES |
|
- HW-UP100(M)
* RO Filtration System *
|
|
- Saving space
In compliance with the new RO technology, HW-UP100(M) is designed for places where feed water has very low water pressure (under 45psi), or where source water contains higher than normal amount of dissolved solids.
- Benefits
It uses high quality booster pump that can provide 100-120psi water pressure to pass through the membrane even with areas under low water pressure.
The booster pump improves the TDS(Total Dissolved Solids) rejection. It is capable to remove over 90~95% of all organics and 99% of all bacterial. HW-UP100(M) meets all different water quality needs.

- Recommended Operating Regulation of RO
|
1. Need enouh flushing after installation and changing filters.
2. It takes 1week to get the correct valve of TDS (after stabilizing RO membrane)
3. Rate of removal and the volume of treated water depends on water temperature, water pressure, condition of raw water and etc.
4. Product Specifications for RO Membrane. |

* UF Filtration System *
|
| Ultrafiltration Membrane |
Basically UF membrane modules come in plate and frame, spiral wound, and tubular configurations.
All configurations have been used successfully in different process applications, each configuration is specially suited for some specific applications and there are many applications where more than one configuration is appropriate. For high purity water, spiral-wound and capillary configurations are generally used. The configuration selected depends on the type and concentration of colloidal material or emulsion. |

| - Factors Affecting the Performance of Ultrafiltration |
|
Flow Across the Membrane Surface.
The permeate rate increases with the flow velocity of the liquid across the membrane surface.
Higher flow also means higher energy consumption and larger pumps. Increasin the flow velocity also reduces the fouling of the membrane surface, Generally, an optimum flow velocity is arrived at by a compromise between the pump horsepower and increase in permeate rate.
Operating Pressure
Permeate rate is directly proportional to the applied pressure across the membrane surface. However, due to increased fouling and compaction the operating pressures rarely exceed 100psig and are generally around 50psig. In some of the capillary-type ultrafiltration membrane modules the operating pressures are even lower due to the physical strength limitation imposed by the membrane module.
Flow Across the membrane Surface.
Permeate rates increase with increasing temperature. However, temperature generally is not a controlled variable. It is important to know the effect of temperature on membrane flux in order to distinguish between a drop in permeate due to a drop in temperature and the effect of other parameters.
