The LH type pressure ultrafiltration membrane components and their integrated systems are high-performance water treatment solutions built upon fully independent intellectual property rights in PVC alloy ultrafiltration membrane technology. This product line not only offers standardized single membrane elements (LH type) but can also be integrated to construct complete ultrafiltration equipment (LG(H) type). With its ultimate filtration precision of 0.01 microns, exceptional water quality, and significant energy-saving characteristics, it serves as a reliable choice for safeguarding water safety and quality. It is a benchmark product widely trusted in the market.
Independent Technology, Market Leader: The core membrane material is a self-developed PVC alloy with full intellectual property rights. It offers stable and reliable performance, leading the market share among similar products.
Ultimate Precision, Superior Water Quality: With a nominal pore size of 0.01 microns, it efficiently removes suspended solids, colloids, bacteria, and viruses. The product water quality is outstanding, with SDI₁₀ < 3 and turbidity < 0.1 NTU, providing perfect feed water for subsequent processes like Reverse Osmosis (RO) or directly producing high-quality water.
Low-Pressure Operation, Energy Efficient: Designed with a low-pressure, high-flux philosophy, its standard filtration flux range is wide (50-200 L/(m²·h)). This ensures high throughput while effectively reducing system energy consumption and offers excellent fouling resistance.
Robust and Durable, High Tolerance: The housing and end caps are made of high-strength PVC or EP resin. The membrane fibers can withstand a wide pH range of 1-14 for chemical cleaning and operate in water temperatures from 0-40°C, offering strong environmental adaptability and a long service life.
The LH type pressure ultrafiltration system, with its high precision, low energy consumption, and stable effluent, serves as core technology for water purification across numerous fields:
Perfect Pretreatment for Reverse Osmosis (RO) Systems: Acts as a safeguard filter for RO, providing feed water with low SDI and low turbidity. This greatly extends RO membrane life, reduces system cleaning frequency, and lowers operating costs. Widely used in seawater desalination, ultrapure water production, and water reuse.
High-Quality Drinking Water Safety Assurance: Used directly for purifying surface water or groundwater, producing effluent that meets and exceeds national drinking water hygiene standards. Suitable for municipal water supply, community water purification, and emergency water supply scenarios.
Industrial Process Water Refinement: Provides a core filtration unit for industries like electronics, power, food & beverage, and pharmaceuticals, ensuring the purity and stability of process water.
Wastewater Advanced Treatment and Reuse: Performs advanced filtration on biologically treated wastewater, achieving extreme removal of suspended solids and microorganisms. The product water can be directly used for landscaping, irrigation, flushing, or as a source for higher-grade reuse.
The LH type pressure ultrafiltration solution, with its reliability proven by extensive applications, excellent energy efficiency, and flexible system configurations, delivers comprehensive value from core membrane elements to complete equipment. It is a solid foundation for water resource purification, quality enhancement, and reuse.
