Advanced Water Treatment Solutions for the Plastic Recycling Industry
Transform plastic washing wastewater into clean, reusable process water through WTT's integrated treatment technologies and sustainable solutions
Critical Challenges in Plastic Recycling Water Management
The plastic recycling industry faces complex water treatment challenges requiring specialized solutions for sustainable operations and regulatory compliance.
Complex Contamination Matrix
Organic and inorganic particles, color residues, fats, oils, surfactants, microplastics and heavy solids from washing cycles create complex treatment requirements.
High Water Quality Requirements
Transparent films and food-grade packaging demand highest purity standards in advanced washing steps for quality recycled products.
Variable Feedstock Composition
Processing PET, HDPE, PP, PE from post-consumer or post-industrial sources creates fluctuating wastewater characteristics requiring adaptive treatment.
Intensive Water Usage
Multiple washing stages using settling tanks, float/sink tanks, and high-pressure systems generate large wastewater volumes requiring efficient treatment.
Environmental Compliance Pressure
Strict discharge regulations require efficient treatment before disposal or reuse to meet environmental standards.
Operational Cost Control
Minimizing fresh water consumption and energy usage while maintaining product quality is essential for profitable operations.
