The Reverse Osmosis Device is a water purification system that uses a semipermeable membrane to desalinate saline water under pressure. Its operation is opposite to the natural osmosis process, hence the term “reverse osmosis,” also known as “inverse osmosis.” By applying a pressure greater than the osmotic pressure, this method can achieve separation, extraction, and purification.

During COD analysis,chloride ions in water samples are readily oxidized by the oxidizing agent,and their high concentrations can lead to elevated measurement results.

Is the effluent failing to meet standards? I’ve compiled all the influencing factors!
During wastewater treatment, a variety of effluent‑quality issues may arise, such as non‑compliant levels of COD, ammonia nitrogen, total nitrogen (TN), and suspended solids (SS). Since the underlying principles of biochemical treatment are essentially the same across different systems, this paper uses domestic wastewater as the case study to summarize the common challenges encountered during operation that lead to effluent non‑compliance.

Are you performing the maintenance and cleaning of your ultrafiltration membrane correctly?
Ultrafiltration membranes are widely used and have proven highly effective in sectors such as the construction industry, pipe manufacturing, wastewater treatment, sealing materials, fibers, and packaging films. Their performance is particularly noteworthy in industrial applications—such as thermal power plants and chemical factories—where they deliver significant social value and comprehensive benefits. However, as operating time increases, ultrafiltration membranes require regular maintenance and cleaning to maintain optimal performance and achieve their intended objectives.

The operating principle of a baghouse dust collector is as follows: Dust-laden gas enters the baghouse, where larger, heavier particles settle under gravity and fall into the hopper. The gas containing finer particulates passes through the filter bags, guided by flow‑diverting plates; the dust is captured, thereby purifying the flue gas. After purification, the dust concentration in the flue gas is ≤50 mg/m³, meeting environmental protection standards.

4. Analysis of Mechanical Damage to Filter Bags: (1) Friction and puncture caused by rough frame surfaces and sharp weld marks. (2) Improper storage, transportation, and installation. (3) Excessive blow‑off pressure leading to bag abrasion. Remedial Measures: (1) Ensure proper maintenance of the frame and keep its surface smooth. (2) Use appropriate packaging; during storage and transport, avoid compression and bending, protect against water and direct sunlight, and handle with care during installation to prevent impacts; never drag the bags on the ground. (3) Adjust the blow‑off pressure.
