How industrial water filtration can improve efficiency and save you money

Over the course of the past couple of decades, industrial water filtration has become one of the most important considerations for the average manufacturing facility in North America. These concerns have only increased as water supplies have dwindled and wastewater contamination standards have become more stringent. All of this has led to the need to choose the right industrial water filters and ...

Conductivity Measurement in high purity water samples below 10 microsiems/cm

High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens'cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is ...

High Purity Boiler Water Production Using Municipal Wastewater at a Combined Cycle Gas-Fired Generating Station

The recovery of wastewater for industrial uses presents many challenges for the design and operation of water treatment equipment. Since the term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water, the water characteristics may have great variability. As such, the equipment to treat wastewater must be robust and ...

Lessons Learned: The Installation of a 300 to 600 gpm Semiconductor High-Purity Water System

The life of a high-purity water treatment project may be compared to roli¡ng a boulder down a dome-shaped hill (1). The project gets rolling with a fairly small nudge. Once ¡t ¡s rolling, however, ¡t takes a great deal of effort (time and money) to change the direction or go back up the hill.

Producing High-Purity Recycled Water for Industrial Applications with Microfiltration and Reverse Osmosis: Lessons Learned

ABSTRACTThe East Bay Municipal Utility District (District), with the assistance of Black & Veatch, studied the feasibility of treating secondary and tertiary effluents using microfiltration (MF) followed by reverse osmosis (RO) to produce high-purity, recycled water for use as boiler make-up water at a local refinery. A pilot-scale test program was developed to demonstrate the ability of the ...

High purify water systems for utility use

Companies in the utility business have a need for high purity water for their operations such as in diesel generator cooling systems and in turbine generator makeup water. Often, utilities can not depend on the city water as the quality is not pure enough and purchasing local water may be expensive. To gain operational and economic advantages, water purification equipment can be added. These ...

A new method estimates TEG purity versus reconcentrator temperature at different levels of pressure in gas dehydration systems

There are several processes and principles for obtaining high triethylene glycol (TEG) purity in gas dehydration process. All methods are based on the principle of reducing the effective partial pressure of water in the vapour space of the glycol reboiler, and hence obtaining a higher glycol concentration at the same temperature. One of the most common methods for enhancement of the glycol ...

A high-performance electropositive filter

Reverse osmosis (RO) membranes have become the industry standard for purification of any feed water source. They are used extensively for producing high-purity, low-conductivity process water. They are also used for producing ultrapure water from fresh water because RO is presumed to be the ultimate purifier. Because RO filters are readily fouled by colloidal particles and biofilms, some method ...

Evolved gas analysis - a high sensitivity study of a solvent of recrystallisation in a pharmaceutical

Introduction Thermogravimetric Analysis (TGA) of materials is commonly used to provide information on the weight loss as a sample is heated or held isothermally. Pharmaceutical materials often show weight losses associated with the loss of solvent/ water, desolvation or decomposition of the sample. This information is then used to assess the purity and stability of the material and its ...
