Pilot plant project for the removal of microplastics
AI summary Read the abstract
This document describes the engineering design of a pilot treatment plant in El Prat de Llobregat, Spain, built to filter microplastics from wastewater at a sewage treatment facility. The system, housed in a shipping container, uses ceramic filtration, optical monitoring and an enzyme process targeting PET plastic, controlled by an automated industrial control system.
PROYECTO: REMPLAST-Q (Piloto Terciario 5 m³/h) FECHA: 2026-10-20AUTOR E INVENTOR: Lázaro López Paz DESARROLLO: Inteligencia Artificial (Gemini Notebook)UBICACIÓN / SEDE: El Prat de Llobregat, Barcelona, España NORMATIVA BASE: ISO 24187 / IEC 61131-3LICENCIA DE REGISTRO: Creative Commons CC-BY-4.0 REPOSITORIO: Zenodo DOI (P-REMPLAST-Q-2026)1. PRESENTACIÓN Y RESUMEN TÉCNICO DEL ANEXOEl presente Anexo Técnico Ilustrado consolida el expediente de ingeniería de detalle, la arquitectura de automatizacióndeterminista y los protocolos de seguridad industrial de la planta piloto preindustrial REMPLAST-Q. Diseñada para operar sobreefluente secundario de Estación Depuradora de Aguas Residuales (EDAR) con una capacidad nominal de 5.0 m³/h (100 m³/díaefectivos en 20 horas de marcha diaria), la instalación se aloja íntegramente en un contenedor marítimo de 20 pies High-Cube(ISO 20' HC) acoplado a un skid exterior cubierto.Toda la responsabilidad técnica, autoría e invención proceden de Lázaro López Paz (El Prat de Llobregat, Barcelona, España)en co-desarrollo con Inteligencia Artificial. La planta integra ultrafiltración cerámica tubular de a-AlnOn/SiC (25 m²), monitoreoóptico en flujo (SE-201) y degradación enzimática selectiva de la fracción PET (R-501 con LCC-ICCG), gobernadaexclusivamente por un PLC Siemens S7-1200 en lógica determinista sin dependencia de computación cuántica ni nube.REGLA DE ORO DE SEGURIDAD INDUSTRIAL: El PLC Siemens S7-1200 mantiene autoridad exclusiva sobre los actuadores. Lasválvulas de aislamiento con la EDAR (V-101 y V-401) son de actuación fail-close por muelle mecánico (<3 s). Ningún interlock deClase S puede ser desactivado o rearmado a distancia

Evaluation of the Presence of Microplastics in Wastewater Treatment Plants: Development and Verification of Strategies for Their Quantification and Removal in Aqueous Streams
AI summary Read the abstract
Researchers evaluated microplastic presence in wastewater treatment plants and developed a pilot capture system capable of detecting, quantifying, and removing microplastic particles from water. The study found that conventional treatment processes are insufficient for complete microplastic removal, highlighting the need for dedicated technologies to address this gap in water treatment infrastructure.
Study of Methods for Removal of Microplastics Composed of Bisphenol A in Wastewater Treatment Plants

Researchers evaluated methods for removing bisphenol A-based microplastics from wastewater treatment plants, finding that current treatment systems are not fully effective at capturing these small plastic particles before they are discharged into waterways.
Screening of microplastics in water and sludge lines of a drinking water treatment plant in Catalonia, Spain
AI summary Read the abstract
Researchers screened water and sludge throughout a drinking water treatment plant near Barcelona, Spain, for microplastics ranging from 20 to 5,000 micrometers. Microplastics were detected at multiple treatment stages and in the sludge, with conventional coagulation-flocculation and filtration providing partial but incomplete removal.

Researchers evaluated a pilot-scale biofilter for removing microplastics from secondary wastewater treatment effluent, finding it effectively polished treated wastewater before environmental discharge by capturing particles across multiple filter zones.
Size- and Polymer-Specific Assessment of Micro- and Nanoplastics in a European Wastewater Treatment System
AI summary Read the abstract
Scientists studied tiny plastic particles in European wastewater treatment plants and found that these facilities can remove most microplastics from sewage, but many still escape into the environment. Even though the treatment plants filter out a lot of plastic pollution, the enormous amount of wastewater they process means millions of plastic particles still end up in rivers and oceans every day. This matters because these plastic particles can eventually make their way into our drinking water and food chain, potentially affecting human health.
