Real-Time Water Quality Monitoring and Automated Disposal System for Process Industry

This research study focuses on the development of a Real-Time Water Quality Monitoring and Automated Disposal System for the textile dyeing industry. The system monitors key water quality parameters pH, temperature, and Total Dissolved Solids (TDS) using IoT enabled sensors. Based on real-time sensor data, it automatically categorizes wastewater into three types reusable water, irrigation-suitable water, and chemically contaminated water. Automated solenoid valves control the flow of water to appropriate channels based on these categories. The system also features a manual mode, allowing users to manually actuate the solenoid valves as needed. Real-time data, including water quality parameters and valve operations, is displayed on the Blynk platform, enabling remote monitoring and control. Furthermore, the project explores the reuse of chemical water in cement manufacturing. This smart solution promotes sustainable water management, reduces environmental impact, and supports resource reuse within the textile dyeing and construction industries.

I. Introduction

The textile dyeing industry is a crucial sub-sector within the textile industry, responsible for imparting vibrant colors and stylish designs to fabrics and textiles. This essential process requires the use of various dyes and chemicals to achieve desired colors and patterns, meeting market trends and customer expectations. However, the dyeing process generates significant volumes of wastewater, posing environmental and operational challenges. This wastewater is often colored and contains harmful dyes, chemicals, and pollutants that can negatively impact the environment if not properly managed. Traditional methods of wastewater characterization in textile dyeing industries involve randomly collecting water samples and testing them in laboratories for parameters such as pH, turbidity, TDS, and COD. This approach is time-consuming, labor-intensive, and delays timely decision-making and proper water disposal. As a result, a substantial portion of wastewater is discharged without appropriate categorization or treatment for reuse. Inefficient wastewater management contributes to high water consumption, environmental pollution, and noncompliance with regulatory standards. Consequently, there is an urgent need to adopt advanced technologies that enhance the effectiveness of wastewater treatment and promote eco-friendly practices in the textile dyeing industry.
