TB 75: Power Plant Installs Advanced Membrane System to Reduce Capital Costs and Decrease Energy Use

This technical brief describes how Liqui-Cel Membrane Contactors were installed as part of an Integrated Membrane System (IMS) in a power plant. This advanced membrane-based industrial water treatment system replaced a conventional water treatment system resulting in reduced capital costs, lowered energy use and the improved water reclaim rate.

TB 76: Liqui-Cel® Membrane Contactor Degassing System Installed to Increase Well Pumping Efficiency in Rockland County New York

This technical brief describes how Liqui-Cel Membrane Contactors were evalulated and used to improve the flow rates of wells operated by United Water of New York (UWNY) by removing dissolved gasses. The reduced operating costs and lower capital requirements gave Liqui-Cel Contactors the edge over competing technologies.

TB 80: Oxygen Removal from Feedwater of a Central District Heating System

In central district heating systems heated water from power plants is distributed to residential and industrial areas by insulated piping networks. Large storage tanks are typically used to safely store heat for use during periods of peak load demand. To prevent internal corrosion and to increase the lifetime of piping and storage tanks, inlet water should be deoxygenated with Liqui-Cel® Membrane Contactors.

TB 72: Chinese Chemical Plant Optimizes Water Treatment with Liqui-Cel® Contactors

This case study describes how a chemical company replaced their double pass RO system with RO+Liqui-Cel to Optimize their process.

TB 68: Chemical Cost Comparison LC vs. Traditional Deaeration System

This technical brief details the process a company goes through when weighing the operating costs and performance of different degassing systems.

Using Membrane Contactors For CO2 Removal To Extend Resin Bed Life
This case study discusses operating savings and efficiency improvements at City Public Service in San Antonio, Texas.  They chose Liqui-Cel Contactors over a forced draft deaerator for CO2 removal from water at their plant to extand resin bed life, lower operating costs, and do away with chemical addition.

TB 62: Liqui-Cel® Membrane Degassing Modules Improve Ice Production at the Ice Palace in Moscow

This case study describes an innovative approach that was used by the Ice Palace in Moscow to produce clearer ice in their arena.

Lucent Technologies Low Level Oxygen Removal
This article summarizes a case study where Liqui-Cel® Membrane deaerators are used at Lucent Technologies to remove oxygen from water to 10 ppb.

14x28 Liqui-Cel® decarbonators are the chemical free choice used to decarbonate water feeding the mixed beds.

TB 56: Power Plant in Thailand Uses Liqui-Cel® Membrane Contactors to Remove CO2 From Water

Liqui-Cel® degasifiers are used to remove CO2 from water that feeds a high pressure boiler.

TB 45: Boiler Feed Water Degassing Lowers Operations Costs and Chemical Usage

Boiler Feed Degassing system in China Removes O2 from water for corrosion control and lowers operating costs.

TB 39: Japanese Brewery Uses Liqui-Cel Contactors in 3 Breweries

Liqui-Cel® degasifiers reduce corrosion by removing O2 and CO2 from water at Kirin Brewery.

TB 38: Chemical-Free Membrane Degassing in Pharmaceutical Plants

Membrane degasifiers are used instead of chemicals for oxygen and carbon dioxide removal from water.

TB 33: Oxygen Removal from Water to 3 ppb at IMEC

Semiconductor research facility utilizes Liqui-Cel® degassing contactors for 3 ppb O2 removal from water.

VLSI chooses Liqui-Cel Contactors over Conventional Vacuum Tower for Deaeration
This paper describes the process and technology that VLSI evaluated for their San Antonio Texas Plant. Liqui-Cel® Contactors were chosen over vacuum deaeration for oxygen removal of < 1ppb.

Mansfield Brewery Uses Liqui-Cel® Membrane Contactors to Nitrogenate Beer
Nitrogen is added to beer with Liqui-Cel® Contactors to control CO2 content and produce a smooth keg beer that mimics cask–conditioned beer while maintaining the ‘head’ characteristics of a keg beer.

Liquid-Liquid Extraction of Aroma Compounds with Hollow Fiber Contactor
This paper details how Liqui-Cel® Membrane Contactors have been successfully used for the extraction of aroma compounds for the food industry. The paper was completed by Unilever Research in the Netherlands and was published in the AIChE Journal, August 2001, Vol. 47, No 8.
