Managing liquid process streams in animal
by-product processing

Animal by-product processing can generate liquid process streams that require dedicated handling, treatment, or concentration. These streams must be considered as part of the full plant concept, not as an afterthought. WALDT helps companies define how effluent should be managed within an integrated rendering or slaughterhouse by-product processing solution.

What is effluent processing?

Effluent processing refers to the handling, treatment, or concentration of liquid streams generated during animal by-product processing. These streams may come from thermal processing, separation, washing, condensation, or other process-related steps.

Depending on the project, effluent may be treated, concentrated through vacuum evaporation, or further processed into a usable output stream. The right route depends on raw material, process design, local requirements, and target commercial use.

Why effluent processing matters

Poorly managed effluent can affect plant operation, environmental performance, odour control, utilities, and total cost of ownership (TCO). It can also limit how efficiently a facility can operate over time. A well-designed effluent processing concept supports cleaner process integration, better resource use, and more predictable long-term operation.

How WALDT can help

WALDT is a specialized engineering and technology partner for animal by-product processing projects.
01

Assessment

We start by understanding the liquid streams generated by the process.

  • Effluent sources and expected volumes
  • Raw material type and process route
  • Composition and variability of liquid streams
  • Site conditions, utilities, and discharge requirements
  • Potential for concentration, reuse, or further processing
02

Technology Study

A Technology Study can define the technical basis for effluent handling and concentration.

  • Effluent stream assessment
  • Mass balance calculations
  • Evaporation or concentration concept
  • Utility and energy consumption assumptions
  • Site and layout constraints
  • Environmental and regulatory considerations
  • Total cost of ownership considerations
03

Integrated process design

WALDT helps connect effluent processing with the wider rendering plant concept.

  • Process water and condensate stream routing
  • Evaporation or concentration system integration
  • Connection with rendering, separation, odour control, and utilities
  • Automation and control requirements
  • Storage, transfer, and output handling
  • Environmental system integration
04

Implementation support

We support the project from concept to reliable industrial operation.

  • Engineering support during project development
  • System integration planning
  • Installation supervision
  • Commissioning and start-up support
  • Operator training
  • Performance validation
  • Long-term technical assistance
