PRODUCT OVERVIEW
Designed around the production task.
Front-end wet pre-washing for film feedstock, configured around contamination level, material condition and the selected washing route.
MATERIAL & PROCESS CONTEXT
Material, process and output context.
Technical configuration is available on request. Please share your material, output target and product specification with the Grace team.
CONFIGURATION ENGINEERING
Engineering front-end wet pre-washing module around the actual material
A recycling system is defined from the actual feedstock and required downstream use, not from a headline model or capacity. Material condition, contamination, safety boundary and each process interface are reviewed together before a project configuration is released.
Material definition
Confirm polymer family, material form, incoming size, contamination profile, moisture, labels, metals, non-target fractions and any restricted or hazardous contents before selecting the route.
Process-route integration
The selected process interface is after infeed or primary reduction and before subsequent washing stages. Each module is balanced with its upstream preparation, downstream handling and the declared target material requirement.
Utilities, residue and safety
Water management, residue handling, ventilation, access, guarding and site constraints are defined with the actual material and local operating conditions; they are not assumed from a generic reference line.
Project confirmation
The final equipment list, operating window, controls and acceptance criteria are confirmed through project engineering, controlled technical review and the agreed validation plan.
FOR A TECHNICAL PROPOSAL
Information that lets us define the right line.
- Contamination, incoming size, material form, water condition and residue handling
- Clear material photos or representative samples, including packaging and contamination condition
- Required target material, downstream use and any purity, moisture or handling expectations
- Factory layout, utilities, water-treatment boundary, safety rules and local regulatory requirements
- Required controls, service access, documentation language and project delivery expectations
This v2 Beta page presents the R&D-signed technical reference for the stated material and process scope. It is not a price, delivery, quality, certification or contractual performance commitment; the final project configuration and acceptance conditions remain subject to controlled engineering review.
TECHNICAL DATA
Representative pre-washer reference models
