Water Intake

Groundwater well screens (often also called well screens, well casing screens, or filter casings), particularly those utilizing the Wedge Wire type, are core components in groundwater extraction and monitoring wells. Their primary function is to ensure groundwater can flow smoothly into the wellbore while effectively blocking sand and gravel from the formation, thereby preventing well clogging and protecting pumping equipment from abrasion.

Subsurface Water Intake Projects are a method of abstracting water resources utilizing the "underflow" found within the gravel and sand layers beneath rivers, streams, or lakes. The principle of this engineering involves setting up water collection facilities beneath the riverbed or banks to efficiently capture the groundwater (i.e., subsurface flow) that has naturally filtered through the porous sand and gravel layers, which is then routed to a water treatment plant for municipal or industrial use.

The screen is the critical component in Subsurface Water Intake Projects. It efficiently collects the water flow while simultaneously blocking sand and debris. Its core feature is a precise, anti-clogging filtration structure, which ensures water purity and protects downstream equipment.

Serves as an essential filtration barrier for seawater intake points, pre-pump filtration, pre-cooler filtration, desalination pre-treatment, aquaculture intake, ship ballast water treatment systems, and more.
