Product Introduction
The drum-type rotary filter is a mechanical filtration system that utilizes gravity or pressure differentials to pass suspended solids through a porous medium, effectively intercepting solid particles and achieving precise solid-liquid separation.

Filter Media:
Constructed from custom-woven stainless steel wire with a pore size of 15–20 microns, the filter media ensures:

• High Porosity: Enables low-resistance liquid passage with optimized pore size.

• Chemical Stability: Excellent corrosion and heat resistance.

• Mechanical Strength: Withstands high pressure and impact, ensuring durability and reliability.

The DSTR series precision filters are widely used in:

• Advanced treatment and upgrading of municipal sewage (e.g., Class B to Class A standards)

• Pretreatment in municipal and industrial wastewater treatment

• Pretreatment for tap water systems

Applications

• Sewage Treatment Plants: Upgrade effluent quality from Class B to Class A standards.

• Reclaimed Water Reuse: Remove insoluble suspended particles to enable water recycling.

• Industrial Wastewater Treatment: Filter process water to meet specific usage or environmental discharge requirements.

Key Features

1. Superior Filter Media:

   • Stainless steel construction ensures uniform pore size, high tensile strength, fast filtration, and long service life.

   • Resists clogging and corrosion, outperforming traditional fiber cloth or polyester materials.

2. Easy Maintenance:

   • Individual mesh modules can be replaced independently without disrupting adjacent filters.

3. High Impact Resistance:

   • Operates effectively with inlet SS concentrations up to 40 mg/L.

4. Continuous Operation:

   • Simultaneous backwashing and filtration ensure uninterrupted performance.

Packing and Delivery

1. Waterproof packing with the international export standard by 20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and Power Cabinet will be packed in Wooden Case or Iron Box. Other Equipment will be packed by Color-Stripes Plastic Cloth.
2. The whole plant machinery size are large as normal, so we will use Waterproof cloth to pack all of them. The motor, gear box or other easily damaged parts, we will put them into box. We have a professional shipping department, they will try their best to save your container quantity.
