Industrial & Municipal Wastewater Treatment Solution

Industrial and municipal wastewater streams require efficient solid-liquid separation to meet discharge regulations, recover resources, and enable water reuse. Our screening systems effectively remove suspended solids, fibers, and debris from various wastewater sources.

Recommended Equipment

  • Rotary Drum Screen (RDS) for primary screening of municipal sewage and industrial effluent.
  • Fine Static Screen or Wedge Wire Screen for removing fine particles (down to 0.25mm) in industrial wastewater.
  • Sludge Dewatering Screw Press or Belt Press for thickening and dewatering of biological/chemical sludge.

Key Benefits

  • Protects downstream processes (like MBR or UV disinfection) by removing damaging solids.
  • Reduces sludge volume and disposal costs through efficient dewatering.
  • Robust, low-maintenance designs suitable for 24/7 operation in harsh environments.

Waste Oil Recycling & Purification Solution

Used lubricating oils, hydraulic oils, and coolant emulsions contain contaminants like metal chips, sludge, and particulates. Effective screening and filtration are crucial for oil recovery, regeneration, or proper disposal, maximizing resource value and minimizing environmental impact.

Recommended Equipment

  • Magnetic Separator followed by a Vibrating Screen to remove ferrous swarf and coarse debris from used oil.
  • Plate & Frame Filter Press or Cartridge Filtration System for fine purification and de-sludging of waste oil.
  • Oil Skimmer or Centrifugal Separator for separating free oil from wastewater sumps or coolant tanks.

Key Benefits

  • Recovers valuable oil for re-refining or reuse, significantly reducing raw material costs.
  • Extends the life of machinery by ensuring the quality of reconditioned oils.
  • Ensures compliance with environmental regulations for waste oil handling and disposal.

Animal Manure & Organic Waste Processing Solution

Livestock manure and other organic wastes require separation of solids from liquids for efficient nutrient management, compost production, biogas feedstock preparation, and reduction of lagoon volumes. Effective screening is key to odor control and resource recovery.

Recommended Equipment

  • Screw Press Separator for high-volume separation of fibrous solids from liquid manure (slurry).
  • Rotary Shear Screen for processing thicker manure with high straw or bedding content.
  • Vibrating Dewatering Screen for further dewatering of separated solids to produce stackable compost feedstock.

Key Benefits

  • Produces nutrient-rich solid fraction for composting or direct soil application.
  • Generates clarified liquid fraction that is easier to store, irrigate, or further treat.
  • Reduces odor, flies, and greenhouse gas emissions from storage lagoons.

Laundry Wastewater Recycling & Lint Removal Solution

Commercial and industrial laundries generate wastewater loaded with lint, fibers, sand, and chemical residues. Efficient screening is essential for protecting plumbing, enabling water reuse, meeting sewer discharge standards, and recovering heat from greywater.

Recommended Equipment

  • Automatic Self-Cleaning Lint Filter (Bag or Cartridge Type) for continuous removal of lint and fibers.
  • Compact Rotary Drum Screen or Disc Filter for integrated water recycling systems in large laundries.
  • Sand & Grit Trap with coarse screen for pre-treatment to remove heavy abrasives that damage pumps.

Key Benefits

  • Enables significant water and detergent savings through effective filtration for reuse.
  • Prevents costly blockages in pipes, pumps, and water meters.
  • Helps laundries meet stringent municipal codes for effluent discharge quality.
