SCREENS

MULTI-RAKED SCREEN

General description

Utilizes a unique filter element system designed to automatically remove a wide range of solids found in conventional municipal and industrial wastewater channels. The elements, mounted on a series of parallel shafts, form an endless moving belt that collects, conveys and discharges solids greater in size than the nominal element spacing.
Solids that are captured out of the wastewater flow are conveyed upward on the belt assembly to be discharged at the rear of the unit. Two-stage, coarse and fine screening are achieved on the forward and recessed faces of the element belt, resulting in some of the lowest head losses in the industry

Advantage

  • housands of installations;
  • ustomized for every application
  • Very low power consumption
  • Low maintenance costs

ROTARY DRUM SCREEN

DH. ROTARY DRUM FINE SCREEN is a very fine screen mounted to the pipeline. It is used mostly for the very fine screening of suspended solid waste of 0.25 - 3.0mm. The product is widely preferred in food, textile, sugar industries and paper mill...
The rotary screen is manufactured through high frequency welding of V - notched wedge wires, coiled in spiral with a special device. Because of this wire provided, it is practically impossible for the sieve to be clogged and the permeability rate is very high.

STATIC FINE SCREEN

DAI HUNG unit is a proven, reliable performer for liquid/solid separation in municipal and industrial applications, particularly for screening fibrous and  nongreasy solids. There are no moving parts, motors, or complicated connections. The Dai Hung is simple and economical to operate.

Q&A

-> An industrial exhaust fan is designed to remove air, heat, and fumes from a workspace, while a centrifugal fan uses centrifugal force to move air efficiently through ducts or systems. Centrifugal fans are commonly used in dust collection and ventilation systems requiring high pressur

-> A cyclone dust collector primarily separates larger dust particles using centrifugal force. It is not effective for fine particles like PM2.5. To remove PM2.5 efficiently, a bag filter or electrostatic precipitator should be used after the cyclone stage

-> A gas scrubber is typically used to treat acidic or chemical exhaust gases such as SO₂, HCl, NH₃, and VOCs. Depending on the scrubbing solution and design, it can also capture particulates and neutralize harmful emissions from industrial processes

-> An industrial mixer is suitable for surface or tank-level mixing in chemical or wastewater treatment systems, while a submersible mixer is ideal for continuous agitation in deep tanks or equalization basins to prevent sedimentation

-> A high-quality submersible mixer typically lasts between 5 to 10 years, depending on material quality, operating conditions, and maintenance frequency. Using stainless steel materials and regular servicing can extend the mixer’s lifetime

-> A belt filter press can process between 5 to 50 cubic meters of sludge per day, depending on sludge concentration, belt width, and machine capacity. Proper conditioning and polymer dosing improve dehydration efficiency

-> Yes, a DAF system is highly effective in separating oil, grease, and suspended solids from food-processing wastewater. By injecting microbubbles, it floats contaminants to the surface for removal, improving overall treatment efficiency
