What's the application of DSM screen?

JX Filtration April 9, 2026 Sieve Bend Screen

DSM Screen is a simple, efficient, and power-free primary solid-liquid separation device. It primarily utilizes the gravity of the water flow and the tilt angle of the screen surface to intercept and separate larger suspended solids. The following are its main application scenarios, particularly suitable for processes requiring high-flow-rate, low-cost pretreatment:

I. Municipal and Domestic Wastewater Treatment

Inlet Pretreatment: As the first physical barrier, installed in the inlet channel of wastewater treatment plants or pumping stations, it removes large floating objects, hair, plastic products, branches, etc., protecting subsequent pumps and precision equipment.
Rainwater Overflow Treatment: Treats initial rainwater in combined sewer systems, screening out larger pollutants.
Sludge Pre-Concentration Before Dewatering: Performs preliminary concentration of thin sludge, reducing the load on subsequent dewatering equipment.

II. Food and Beverage Processing Industry

Fruit and Vegetable Washing Wastewater: Separates processing residues such as peels, seeds, stems, and leaves.
Slaughterhouse and Meat Processing Wastewater: Removes feathers, meat scraps, fat, and visceral fragments.
Brewing and Beverage Production: Filters grain husks, fruit pits, and fruit fiber.
Starch Processing: Recovers valuable fibrous materials from wash water.

III. Paper and Pulp Industry:

White Water Recovery System: Screens out fine fibers and fillers in the wet end circulating water of paper machines, enabling reuse and saving water and chemicals.
Waste Paper Pulping Pretreatment: Removes light impurities such as plastic flakes, staples, and tape from pulp after pulping.

IV. Agriculture and Livestock Industry:

Livestock Wastewater (Pig, Cattle, Poultry): Effectively separates solid particles, feed residue, and bedding from feces, greatly reducing the load on subsequent biochemical treatment.
Agricultural Product Processing Center Wastewater: Treats high-solids wastewater generated during washing and grading processes.

V. Aquaculture and Water Treatment:

Aquaculture Recirculating Aquaculture System: As the first stage of mechanical filtration, quickly removes solid waste such as fish feces and uneaten feed, maintaining water cleanliness.
Surface water intakes: For water intakes from rivers and lakes, pre-screening removes aquatic plants, floating debris, etc.

VI. Other industrial sectors

Textile industry: Treats thread ends and fiber scraps from desizing and dyeing wastewater.
Car wash wastewater reuse: Primary filtration removes visible impurities such as silt, leaves, etc.Mining and sand washing plants: Recovers coarse particles from runoff or process water.

JX Filtration offers DSM screens in various materials (e.g., 304/316 stainless steel), with screen openings (typically 0.25mm to 3mm) and custom sizes to suit different flow rates and impurity characteristics. If you have specific flow rate, water quality (especially solids type and content), or installation space information, we can provide you with more precise selection advice.
