Engineering Case
A dyeing and printing enterprise in Guangdong
In this water reclamation project, the raw water is textile dyeing wastewater. Through pretreatment and nanofiltration (NF) treatment, the produced water is reused as process water. In October 2022 and February 2023, the NF membrane elements in Train AB and Train CD were replaced respectively, with a total replacement quantity of 720 elements. Since commissioning, the NF system has maintained stable operation, with both produced water flow rate and quality currently meeting the owner's specifications.

A chemical fiber project in Henan
This water reuse project uses surface water as its feed source. Through pretreatment, the produced water is utilized as process water for chemical fiber production and boiler makeup water. The factory began using KeenSen membrane elements since 2017, with a cumulative replacement quantity of 2,000 units. In 2022, the project continued using KeenSen BW-8040FR fouling-resistant membrane elements. The reverse osmosis system employing KeenSen membrane elements in this water production plant operates stably, currently maintaining a salt rejection rate exceeding 98%. Both the produced water flow rate and quality consistently meet the owner's requirements.
