20TPH + 10TPH Reclaimed Water Reuse

20TPH Water Treatment Project for Textile Industry Water Reuse in India

With the increasing global attention to sustainable development, industrial water reuse has become a standard practice in many industries. Especially in water-stressed countries such as India, water reuse projects can not only save water resources, but also reduce operating costs and improve the competitiveness of enterprises. This article will introduce a 20TPH (20 tons per hour) textile industry water reuse project, which successfully reduced the system inlet TDS (total dissolved solids) from 6000ppm to a level suitable for reuse, achieving efficient recycling of water.

• Project Background

India is one of the world's largest textile producers and exporters. However, the textile industry is a highly water-consuming industry, especially in the dyeing and finishing process, which requires a large amount of clean water. In order to meet the dual challenges of water shortage and environmental protection, many textile companies began to seek effective water reuse solutions. The 20TPH water treatment project came into being in this context.

• System Overview

The system water was treated for the customer at the third level. After the clarification, the BOD, COD and TDS of the wastewater were still high. The project adopted a comprehensive water treatment system, including pretreatment, reverse osmosis (RO) and other key technologies to ensure that the treated water quality meets the standards for reuse in the textile industry. The following are the main components and features of the system:

• Pretreatment

Quartz sand filtration: large particle impurities and suspended solids in the water are removed by sand filters.

Activated carbon filtration: organic matter, odor and color in the water are removed using activated carbon filters to further purify the water quality.

• Reverse Osmosis (RO) System

The system uses reverse osmosis technology to remove dissolved solids, ions and other impurities using semi-permeable membranes. The RO system operates at high pressure, usually about 15 kg/cm2, to ensure efficient separation.

• Water treatment equipment

PLC control system: The entire system is managed by an advanced programmable logic controller (PLC) to ensure precise control and automation. The user-friendly interface facilitates monitoring and maintenance.

Sensors and monitoring systems: The integrated sensors and monitoring systems provide real-time water quality, flow and system performance data for proactive maintenance and optimization.

• Project implementation and effect

System inlet TDS 6000ppm

The inlet TDS of this project is as high as 6000ppm, which is much higher than the standard of conventional industrial water. Through pretreatment, reverse osmosis and other multi-stage treatment technologies, the system successfully reduced TDS to below 200ppm, meeting the standard of textile industry reuse.

Output water is used again in the textile industry

The treated water fully meets the water requirements of the textile industry and can be reused in dyeing, finishing and other process links. This not only greatly reduces the consumption of fresh water, but also reduces the amount of wastewater discharged, and realizes the recycling of resources.

• Economic and environmental benefits

Economic benefits: Through water reuse, the company significantly reduces the purchase cost of fresh water and wastewater treatment costs, and improves the overall operating efficiency.

Environmental benefits: Reduced dependence on groundwater and surface water, reduced pressure on the environment, and met the requirements of sustainable development.

The successful implementation of the 20TPH water treatment project for water reuse in the textile industry in India demonstrates the great potential of advanced water treatment technology in solving industrial water problems. Through systematic pretreatment and reverse osmosis technology, the project not only reduced the system influent TDS from 6000ppm to a level suitable for reuse, but also brought significant economic and environmental benefits to the company. This project provides valuable reference experience for other textile companies and industrial fields, and promotes the efficient recycling and sustainable development of water resources.
