Animal and Poultry Excrement Treatment System

The Comprehensive Solution for Sanitizing, Separating, and Stabilizing Liquid and Solid Waste Streams

The Animal and Poultry Excrement Treatment System is a modular, integrated processing plant designed for large-scale operations that handle mixed or slurry-based waste. It goes beyond basic homogenization to perform critical functions such as solid-liquid separation, pasteurization (thermal treatment), advanced mixing, and slurry conditioning. This system transforms raw, potentially hazardous excrement into sanitized, stabilized, and value-segregated outputs—such as nutrient-rich liquid fertilizer, dewatered solid cake for composting, and hygienic feedstock for biogas digesters—ensuring environmental compliance and resource recovery.

Animal and Poultry Excrement Treatment System

Key Features

  • Modular, Integrated Design

    Configured from standardized modules (reception, separation, thermal, mixing) to create a custom treatment train tailored to specific input waste and desired end-products.

  • Solid-Liquid Separation Core

    Incorporates robust mechanical separators (e.g., screw presses, decanter centrifuges) to efficiently split raw slurry into a solid fraction (for composting) and a liquid fraction (for further treatment or liquid fertilizer).

  • Thermal Treatment (Pasteurization) Module

    An optional heated tank or continuous flow heater that raises the material temperature to a defined set-point (e.g., 70°C for 1 hour) to eliminate pathogens, weed seeds, and comply with strict organic safety standards.

  • Advanced Process Control & Monitoring

    A central PLC system monitors and controls all stages—separation efficiency, temperature, retention time, chemical dosing—ensuring consistent output quality and process reliability.

  • Hygienic & Corrosion-Resistant Construction

    Entire system built using stainless steel (AISI 304/316) for critical contact parts to withstand corrosive salts, acids, and frequent high-pressure washing.

Advantages

  • Produces Multiple, Marketable Outputs

    Creates distinct product streams: a dewatered solid ideal for composting/granulation, a clarified liquid for fertigation or further concentration, and sanitized digestate.

  • Ensures Product Safety & Regulatory Compliance

    The integrated thermal treatment module guarantees pathogen reduction, allowing the safe use of treated products in agriculture and meeting stringent international (e.g., EU) biosolid regulations.

  • Maximizes Nutrient Recovery & Utilization

    Separates and conditions nutrients into forms that are more readily available to plants or easier to handle, reducing overall nutrient loss from the waste stream.

  • Reduces Volume & Transportation Costs

    Dewatering significantly reduces the weight and volume of solids for off-site composting or disposal, leading to major logistics savings.

  • Enables Flexible, Future-Proof Operations

    The modular nature allows for capacity expansion or process reconfiguration (e.g., adding a biogas loop) as business needs evolve.

Applicable Raw Materials

  • Slurry & Liquid Manure

    From piggeries, dairy lagoons, and poultry washdown systems.

  • Mixed Excrement with Flush Water

    Common in modern housed animal operations.

  • Food Processing Wastewater

    High-organic-content liquids requiring treatment and resource recovery.

  • Biogas Plant Digestate

    For post-digestion treatment to stabilize and sanitize the effluent before land application.

Basic Structure & Components

Animal and Poultry Excrement Treatment System
Reception & Pre-Screening Module

Incoming waste is dumped into a pit, passed through a fine screen to remove hairs and fibers, and pumped to the next stage.

Solid-Liquid Separation Module

The core mechanical separation unit (screw press, centrifuge).

Thermal Treatment Module (Optional)

A heated, agitated tank with precise temperature control for the liquid or solid stream.

Liquid Conditioning & Storage Module

Tanks for adjusting the pH or adding flocculants to the liquid fraction, followed by storage lagoons or tanks.

Solid Conveying & Mixing Module

A conveyor moves dewatered solids to a mixer for amendment addition before composting.

Control Room & Power Distribution

Houses the main PLC, HMI, and electrical systems.

Pumping & Piping Network

Connects all modules with appropriate pumps and valves.

Key Differentiators vs. Other Pre-Treatment Equipment

The Pre-Mixer is for conditioning solid-rich manure. This Treatment System is for processing slurry and achieving advanced outcomes like pasteurization and precise separation. It handles a different material state and delivers a higher level of processing.

A standalone separator is a single component. This system is an integrated process train that may include pre-screening, chemical dosing, thermal treatment, and controlled discharge, managed by a unified automation system for a complete solution.

Lagoons are for passive storage and partial settlement. This system provides active, controlled, and rapid treatment that reduces odor, recovers resources actively, and produces defined outputs year-round, independent of weather.

Direct composting of raw slurry is difficult and slow. This system pre-processes the slurry into an optimal solid feedstock for composting and creates an additional liquid product, maximizing the value extracted from the waste.

It is the premium, large-scale processing solution for intensive livestock operations, regional waste processors, and value-conscious investors who need to transform liquid waste liabilities into compliant, safe, and marketable resources while future-proofing their operations.
