The LP (low pressure) series of aromatic polyamide compound membrane elements developed by Vontron Technology Co., Ltd. has the properties of low-pressure operation, high permeate flow, and excellent desalination and is applicable to the desalination of brackish water. Besides, it is particularly applicable to the fabrication of high-purity water for the electronic industry and electric power industry owing to its excellent performance in removing soluble salts, TOC, SiO2, etc. Being suitable for desalting such water sources as surface water, underground water, tap water, and municipal water, etc., the LP series is mainly applicable to the treatment of various industrial water such as industrial-purpose pure water, boiler water replenishment in power plants, and can be also applied to such brackish water applications, such as treatment of high-concentration saline wastewater and production of beverage-purpose water.
LP series of the low-pressure elements is normally suitable for the treatment of brackish water, surface water, underground water, and municipality water with TDS that is less than 10000ppm. It is mainly used for producing various scales of bottle water, drinking water, industrial used pure water, high purity water, boiler replenishment water, also for wastewater reuse, material concentration, purification, and refining purposes.
Model | Active Membrane Area ft2(m2) | Spacer Thickness mil | Permeate Flow GPD(m3/d) | Stable Rejection Rate % | Minimun Rejection Rate & |
LP100 | 100 (9.3) | 28 | 2500 (9.4) | 99.7 | 99.5 |
LP11-4040 | 90 (8.4) | 28 | 3000 (11.4) | 99.3 | 99.0 |
LP21-4040 | 100 (8.4) | 28 | 2400 (9.1) | 99.5 | 99.3 |
Note: The permeate flow listed in the table is the average value. The permeate flow of single element is tolerance to ±15% of this value.
The ULP (ultra-low pressure) series of aromatic polyamide compound membrane elements developed by Vontron Technology Co., Ltd for the treatment of surface water and underground water. Its operation is about 2/3 of the low-pressure membrane, and the rejection rate can reach 99%. Thus it can reduce the investment cost of related pumps, pipelines, containers, and other equipment and operation costs of reverse osmosis system, and improve economic benefits.
ULP RO element is normally suitable for the treatment of brackish water, surface water, underground water, and municipality water with TDS that is less than 2000ppm. It is mainly used for producing various scales of bottle water, drinking water, boiler replenishment water, food processing, and pharmaceutical manufacturing industries, and other fields.
