Case Studies


Backwash Water Recovery: A Membrane System Retrofit

With a finite water source, drinking water utilities need a high recovery rate of the water treatment system to support potable demands of the growing population. In this case study, read about one city whose treatment plant operators were experiencing problems of lower throughput, higher chemical cleanings, and more frequent fiber repair events with their current PUF membrane system. Nanostone Water was asked to retrofit a secondary skid to demonstrate the performance of the Nanostone CM-151™ ceramic membrane.

Chemical Refinery Waste Water Reuse

A chemical refinery located in Qinghai China operated a non-biological waste water treatment plant with chemical precipitation followed by clarification, conventional media filtration, and finally with reverse osmosis (RO).

Coal to Chemical Waste Water Reuse

Refining coal to other materials is known as CTX, and is a large industry in China. Waste water from the CTX process is difficult to treat industrial waste water. Regular biological treatment is not enough to meet discharge requirements and so the facilities must find ways to reuse this water prior a zero liquid discharge system. Ultrafiltration and RO are the technologies of choice in this application to enable water reuse. A ceramic UF membrane is a promising upgrade for those looking for a more robust UF choice for this type of waste water treatment.

Cold Source Water for Industrial Makeup

Industrial companies require clean water for cooling, boiler makeup, and a variety of manufacturing processes. It is common to use ultrafiltration or microfiltration (UF/MF) membranes to treat the incoming water supply to reduce turbidity and suspended solids of industrial process water directly, or in use as pretreatment to protect the performance of Reverse Osmosis (RO) membranes.

Power Plant Boiler Feed Water Makeup

Around the world, end users who have had a poor experience with PUF membranes are looking for more robust alternatives for their boiler feed water makeup system. The Nanostone CM-151 CUF membrane has a similar process design to PUF and can directly replace PUF modules with minimal changes to the rest of the system.
