Major Chinese UF order for inge watertechnologies
A major order from China for ultrafiltration (UF) equipment was announced on 25 May 2011 by inge watertechnologies AG, which is going to be taken over by BASF later this year.
The paper factory, run by Lee & Man Paper Manufacturing Ltd, has an annual production capacity of 730,000 t of corrugated base paper. Producing boiler-feed water for steam generation requires 65,000 m³/d of ultrafiltrated water.
The raw water for the factory comes from the Zhujiang River, which is heavily contaminated, so, before the water can be used in the production process, it must be cleaned using UF modules.
High levels of turbidity and organic content put the quality of UF membranes to the test despite regular automated backwash processes, but the robustness of inge's membranes offers levels of performance that have greatly impressed the company's Chinese customers, says the company.
