Selection Guide:

High Concentration  High Anti-Pollution

Certified by: TÜV, CE, ISO9001, ISO14001, OHSAS 18001

High Concentration

★Flow Distributor: Patented Design

The coin-slot design of the flow distributor ensures that the feed flows over the membrane surface in a radar scanning manner, creating a vortex-like spiral throughout the membrane column. This reduces the transmembrane pressure difference to only 2-3 kg, resulting in a 50% reduction in pressure loss compared to traditional DT systems, making it more energy-efficient.

★Membrane Sheets: Patented Material Modification Formula and Special Membrane Manufacturing Process with Larger Membrane Area

1. Optimized molecular structure of the support layer of the membrane sheets, enhancing compressive strength and preventing compaction under high pressure.

2. Improved stability of the bridging polyamide multi-dimensional structure in the functional separation layer, leading to more stable membrane performance and greater resistance to chemical shocks.

3. Membrane area increased by 20% compared to traditional DT, offering better cost-effectiveness.

★Membrane Module: Special Structural Design

Designed with a high-pressure-resistant structure, the membrane module does not deform under high pressure, allowing safe operation at up to 160 bar, which is 3-5 times higher than traditional spiral-wound RO systems. It offers nearly double the concentration ratio compared to traditional DT, enabling ultra-concentration and reduced evaporation.

High Anti-Pollution

1. The membrane sheets have a thicker separation layer (approximately twice that of traditional DT), improving cleanability and extending the lifespan of the membrane.

2. The membrane surface is electrically neutral, reducing the adhesion of pollutants and microorganisms, thus being more resistant to fouling.

3. Open channel design with a flow channel width of 2.5 mm (an increase of over 66% compared to traditional DT), wider fluid channels prevent clogging, suitable for concentrating high-concentration, high-salinity, and high-organic content materials, requiring less pretreatment and providing better anti-fouling performance.

4. Linear protrusion design of the flow distributor creates turbulence at the protrusions, with a Reynolds number Re > 2500, resulting in better self-cleaning effects and reduced cleaning frequency.
