The ROSS™ System is a simplified, yet robust solution for the treatment of oilfield produced water. Based on CeraMem® ceramic membrane technology, this system provides removal of oil and silica as well as softening of the water simultaneously in a fully modular process train.
It is ideal for incremental capacity expansions to oil production facilities to ease bottlenecks in production from existing, underperforming or undersized water treatment plants.
Optimizing Existing Pump Designs Through Cost-Effective Simulation By Glenn Dorsch, P.E., and Kent Keeran, Vaughan Company Inc.
The unique requirements and suction arrangement of chopper pumps make it difficult to apply standard impeller design practices to achieve the desired hydraulic performance. Past practices have approximated head and flow at best efficiency for new designs, but it has been difficult to predict head for other flow points, and almost impossible to predict pump efficiency.
Boiler Feed Water Degasification: New Methods For Optimized Performance By Membrana
This report reviews various system designs and discusses how membrane contactors can be optimized in boiler feed water applications for removal of dissolved oxygen as well as carbon dioxide. The report also highlights what advantages membrane systems have over conventional oxygen and carbon dioxide removal technologies.
3 Solutions For Water Pollution: Detention, Retention, And Water Hazard Ponds By Robin Bio, Otterbine Barebo, Inc.
Waterbodies have long been considered one of man's favorite amusements in nature's vast playground. Despite this, we've treated them haphazardly and, especially in the last five decades, our carelessness has caused great stress on waterways. Pollution plagues many more ponds now than ever. The good news is we are now beginning to mend our past actions by employing detention, retention, and water hazard ponds as the needles and thread.
Nitrate Plus Nitrite Analysis By Nitrate Reductase By William Lipps and Libby Badgett, OI Analytical
The U.S. Geological Survey has approved methods for determination of nitrate plus nitrite in water by enzymatic reduction and colorimetric measurement. Automated on discrete analyzers, the methods eliminate use of toxic cadmium metal for nitrate reduction. This application note describes the nitrate reductase method.
Managing A High-Risk Treatment Change With Monitoring And Control By Katy Guthrie, Hach Company
As utilities face compliance deadlines under the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR), some are forced to consider alternative treatments. Choosing the right alternative treatment depends on its effectiveness, the cost and complexity of implementation and operation, and the potential for the chosen treatment to cause additional problems in the system.

The CleanSea advanced shipboard wastewater treatment system, from Headworks BIO Inc., has specifically been designed for the demands at sea and is currently installed on the largest cruise ship in the world, the Oasis of the Seas.
The Reliant Model 2400 Optical Dissolved Oxygen (DO) Monitoring and Control System is an economical, full-featured optical dissolved oxygen analyzer that offers full-featured optical DO capability and a long-life optical sensor that remains in calibration for at least a year.
FEDI stacks are designed to produce high-purity water, up to 18 MO.cm, using a patented process with double sets of electrodes per stack. FEDI replaces mixed-bed technology and produces pure water continuously without the use of regeneration chemicals.
Enormous job ahead? The MegaMc 1600 4-Jaw fusion machine can tackle the largest of pipe jobs, with the ability to butt-fuse pipe sizes from 20" OD to 63" OD. The newest MegaMc machine features four jaws with 30,000 lbs. of clamping force per jaw for improved gripping and rerounding of pipe.
KLa jet aerators transfer oxygen by simultaneously introducing large volumes of high kinetic energy liquid and air through a series of jet nozzles. The high-velocity liquid exits the inner primary jet and rapidly mixes with the in-coming air in the outer jet.
