① Suitable for municipal wastewater, domestic sewage, and organic industrial wastewater treatment.
② Maximum transmembrane pressure during operation:

DUBHE Reverse Osmosis Membrane Elements are spiral-wound thin-film composite elements based on aromatic polyamide separation layers, designed for high-efficiency desalination and water purification. Covering extremely low-pressure, ultra-low-pressure, low-pressure, medium/high-pressure, anti-fouling, and seawater desalination series in standard 4040/8040 sizes, they deliver stable salt rejection up to 99.7% and high permeate flow with optimized hydrodynamic structure and strong fouling resistance. Suitable for municipal water, brackish water, seawater, industrial water, ultrapure water production, wastewater reclamation, and zero liquid discharge projects, they feature stable performance, low energy consumption, dry shipping for easy transport and storage, and reliable long-term operation under wide pH and temperature conditions.

The TMY20D-400 is a high-rejection, high-productivity, high chemical durability, and fouling-resistant membrane element manufactured with the latest materials and production technology. With an effective membrane area of 400 square feet and a 34-mil feed spacer, it is suitable for various applications including desalination of brackish water with TDS up to 10,000 ppm, desalination of slightly polluted surface water, and reuse of cooling tower blowdown water. The TMY20D-400 is currently the brackish water membrane element with the highest water production and highest salt rejection; it features the widest cleaning pH range (pH 1-13), enabling quick and effective resolution of membrane fouling issues; the RO membrane can withstand minor hypochlorite exposure incidents within a certain range caused by operational errors, thereby enhancing system safety.

The HFUG-2020AN membrane module is Toray's latest innovative UF product, characterized by smaller hollow fiber diameters while offering improved membrane durability and performance. This results in an increased surface area per membrane module, thereby enhancing water production capacity.

The Membrane Bioreactor (MBR) process combines biological treatment with advanced membrane filtration technology. In this system, biodegradable pollutants are broken down by bacteria and microorganisms. Following this biological treatment stage, the clarified water is separated from the activated sludge through the filtration action of the immersed membranes
