Sloped Screen Solid-liquid Separator
The equipment can effectively filter or recover suspended matter, floating matter and sediment, and is suitable for the treatment of farm animal manure, wine residue, slaughter sewage, biogas residue liquid, and food waste water.
Description
IEPP® Slope screen solid-liquid separator is used to separate coarse solids from diluted raw pig manure.
The equipment is generally performed as a pre-treatment for subsequent manure treatment processes, reduce organic matter loading to storages/lagoons, reduce GHG emissions from long-term storages, facilitate pumping to distant fields/storages, and/or use of separated solids for stall bedding/compost media.
Primary Benefits
Removal of organic matter in theory can contribute to manure storage odor reduction overall but in practice daily odor emission can be more noticeable.
Reduce organic matter loading to storages/lagoons.
Reduce GHG emissions from long-term storages.
Use of separated solids for stall bedding/compost media.
Secondary Benefits
Pre-treatment for subsequent manure treatment processes
Nutrient separation – about 20% of the mass of the original manure nutrient mass is contained in the separated solids.
Solid-liquid separation provides the opportunity for farms to more easily pump manure long distances thus reducing manure hauling with tanker trucks.
Step 1: The sewage is sucked up from the cesspool by the sewage pump. Through the slant 45 V-shaped wire screen, most of the water is filtered by gravity.
Step 2: The material flows to the spiral blade through the vibration motor and then is transmitted to the rotary drum screen filter by the spiral blade.
Step 3: In the drum screen, a part of the sewage flows out through the extrusion, and the extruded material comes out from the discharge port.
