"Industries that must treat or pretreat their wastewater face varied challenges. Any given facility’s needs are best met by a total systems approach (TSA) — a fully integrated solution that includes all pieces of the puzzle instead of uncoordinated components and systems. The approach includes a collaborative evaluation up front to understand a facility’s requirements, apply proven designs and materials, and select innovative products that achieve the optimum water quality at the best life cycle cost."

"When the topic of discussion is making ice cream, the first thing that comes to mind isn’t heat, but at Nestlé’s Ice Cream factory in Tulare, California, heat is recovered from air-cooled air compressors to heat process water."

A Different Approach to Understanding Power Factor (Second of Three Parts)

Pumps & Systems, Oct. 2014, by Joe Evans.

"I hope that my last column (Pumps & Systems, September 2014) provided a clearer definition of power factor and how it can be calculated. Power factor can also be explained using a vector triangle, but comparing the voltage and current wave forms is more intuitive and can lead to a clearer understanding of what is actually going on."

PSU Selling Carbon Credits to Chevrolet, Helping Offset Cost of Energy Efficiency

The Oregonian, Oct. 22, 2014, by Ted Sickinger.
http://www.oregonlive.com/business/index.ssf/2014/10/psu_selling_carbon_credits_to.html

"Portland State University is selling the carbon credits generated by energy efficiency projects during a two and half year period to Chevrolet.

The car giant is looking to burnish it environmental credibility with a voluntary carbon reduction initiative, and is buying carbon credits from 12 universities toward a goal of reducing carbon emissions by 8 million tons."


HP Supercomputer at NREL Garners Top Honor

National Renewable Energy Laboratory (NREL) Feature News, Oct. 13, 2014.
http://www.nrel.gov/news/features/feature_detail.cfm/feature_id=15403

"A supercomputer created by Hewlett-Packard (HP) and the Energy Department's National Renewable Energy Laboratory (NREL) that uses warm water to cool its servers, and then re-uses that water to heat its building, has been honored as one of the top technological innovations of the year by R&D Magazine."

Compressed Air Challenge: Maintaining Peak Compressed Air Efficiency

Maintenance Technology, Sept. 2014, by Ron Marshall.
http://www.maintenancetechnology.com/2014/09/compressed-air-challenge-maintaining-peak-compressed-air-efficiency/

"A well-maintained [compressed air] system will provide an uninterrupted supply of cool, clean and dry compressed air at a stable and appropriate pressure in the most efficient manner possible. Poorly maintained systems have frequent system shutdowns, heat or moisture problems, exhibit system pressures that fluctuate wildly at levels that are too high to produce efficiently, and typically waste air due to leakage.  ...here are several key maintenance-related points to consider for trouble-free compressed air system operation."

Energy Efficiency Advocates Optimistic About PACE Program [Texas]

The Texas Tribune, Oct. 7, 2014, by Jim Malewitz.
http://www.texastribune.org/2014/10/07/pace-loan-program-energy-efficiency-gains-momentum/

"PACE [Property Assessed Clean Energy] allows commercial and industrial property owners to use a property tax lien to finance energy efficiency upgrades like solar panels and water recycling systems. PACE programs bill an owner through the lien and forward payments to a private lender. Under a smooth-running program, property owners pay less than what they save on their energy bills. If a property is sold, the new owner inherits the debt — a rule meant to further reduce the risks of investment."
