Description

Technical Field

[0001] This utility model relates to the field of seawater desalination technology, and in particular to a seawater desalination impurity pretreatment device. Background Technology

[0002] Since the natural supply of freshwater is finite, freshwater scarcity is becoming a pressing problem in many parts of the world. Seawater desalination technology, which produces freshwater through desalination, is an important means of alleviating this shortage. Seawater is a complex system, especially in waters near land, containing large amounts of colloids, suspended particles, microorganisms, bacteria, dissolved organic matter, and inorganic matter. During reverse osmosis desalination, large amounts of colloids and suspended particles can clog pipelines, causing membrane fouling. Microorganisms and bacteria can erode membrane elements, and their residues may deposit on the membrane surface, causing further fouling. Therefore, pre-treatment filtration before desalination is crucial.

[0003] Seawater filtration devices often experience filter screen blockage due to the accumulation of impurities during operation, leading to frequent shutdowns for manual cleaning. This process is cumbersome, time-consuming, and labor-intensive, reducing overall work efficiency and equipment usability. Utility Model Content
