Transforming wastewater solids into ‘gold’ through incineration

Incincerator art Alchemists of the Middle Ages sought the magic of converting ordinary materials to gold. The alchemists of the 21st century seek something similar, but the new “gold” is energy — particularly green energy. Effective use of incineration to reduce the volume of wastewater solids updates the zero-energy aspirations of the modern alchemist, while sound science and engineering negate the need for magic. Energy production is feasible today with wastewater solids incineration.

Brewers getting crafty about reducing water, energy use

When a major brewer wants to cut water or energy consumption, it might invest in next-generation anaerobic digestion systems or study ways to wring new savings from its supply chain.

A craft brewer, on the other hand, might simply change the nozzles on its bottle-cleaning equipment.

January 2013

Tried and true


Along with the holidays come the TV commercials for all of the newest, fastest, greatest, and most perfect gifts. It’s not until January rolls around that some use and trial and error reveal which of those gadgets are truly useful.

The same goes for technology and equipment related to water treatment. The January issue examines several cases where different types of automation and controls have proven themselves.

For example, read about how a California utility put into place real-time control of solids retention time to help provide a more consistent food to microorganism ratio as well as to control Nocardia blooms. The plant tested four types of self-cleaning total suspended solids analyzers to find the one that would work best and then coupled that to solids retention time control software. The results are promising.

Technology also can help manage data beyond treatment processes. In Michigan, a utility implemented a condition-based maintenance plan based on a computerized maintenance management system. The system incorporates real-time data into assessments about the health of equipment so that maintenance work can be done when it is actually necessary — not according to a rigid schedule.

A Florida estuary program used technology to take a wider view. The program turned to a collaborative data management system that uses geographic information systems to collate extensive collaboration among stakeholders, including state and federal regulators, local municipalities, scientists, and local industry. In addition to collecting the data, the tool enables users and the public to see progress on local water quality.
