An Overview of BNR Processes for Design, Rerates, and Upgrades    1 PDH

When permit limits change, influent characteristics shift, or capacity thresholds are exceeded, the most frequent response is plant expansion – add concrete, piping – build it bigger and it will meet the new target. But at what expense? Nine times out of ten, if not more often, adding 25%, 50%, or more capacity or meeting new performance criteria does not require a major capital project; instead, it requires assessment of the current plant performance, relief of its pinch points, and a different operational strategy. More engineering and less construction are needed, not cookie cutter responses or assumptions but process engineering based upon real data from your zip code; more pencils and napkins, testing, and rational thinking are required. The pertinent data needed, some of the many options available, and the strategies of successful and unsuccessful implementations are presented.

Beyond SCADA – How to Provide Performance Guarantees and Insure Success 1 PDH

Supervisory Control And Data Acquisition (SCADA) systems as traditionally implemented do not provide the information nor do they provide the control to allow operations staff, or designers, to turn their backs on a facility and sleep contentedly knowing with certainty that permits will be met and that the public’s interests will be fulfilled. Assumptions, as the saying goes, typically make for undesirable outcomes; conventional SCADA systems are based upon assumptions and self-fulfilling prophecies. The “fix” for the problem, the key to resting assured of the outcome, is not just collecting the data but using it to control the minute by minute performance of the facility – with or without operators. Operators are needed, maintenance is needed, but not to repeatedly execute and monitor decisions already made and practices established. Presented for owners and engineers are strategies and examples of how much data to gather, how frequently, what to do with it, and how to implement automation so that it pays for itself in weeks or months, not years.

Chlorination Control    1 PDH

Chlorination is still the preferred choice for disinfection of potable water and wastewater effluent. As a treatment process, however, implementation and operational practices are, more often than not, poorly controlled and at best, poorly understood. The competing reactions of chlorine are presented with various control methods that are dictated by the background water chemistry and the desired outcome and economics. Specifically included are the roles played by ammonia nitrogen, organic nitrogen, metals, and particulates in the control strategy and operation of chlorine disinfection.

Common Myths of Wastewater Process Design and Operation    1 PDH

The “make it work” approach, “my sludge can’t read”, or “no one told me” schools of operation have led to full scale, real life, real world examples to debunk many wastewater design and process truisms taught as gospel.  Many of these have a basis in history or “popular science”; some are correlations that have not borne the test of time.  For certain, they are all to be found in one textbook, in a study guide, or on a whiteboard that you have seen and would swear is true.  This course is not for those who haven’t finished their license exams.

Distributed Power versus Power Distribution    1 PDH

More than 75% of repair and replacement maintenance expenses can be assigned to one or both of two problems: improper or inadequate grounding, or poor power quality, voltage imbalance. Typically 15 – 18% of expansion projects and facilities upgrades is spent on electrical supply and distribution with an additional 8-15% spent on controls and automation. Whether correcting an unbalanced budget, implementing new controls, or tackling a full fledge facilities upgrade, the key to short, legitimate returns on investment is to be found most often in getting the power distribution correct, and having it perform correctly. With reasonable purpose, and by code, a power distribution system is designed for full load – operating at full installed capacity; in practice, rarely if ever does that occur. Proper power distribution with delivered quality power can be as simple as rearranging breakers in a panel based upon current, real time usage data. New building construction, unnecessary cooling requirements (real power and real dollars every month), and HVAC additions can be eliminated by paying attention to the implementation details; automation with attention to concurrently distributing power loads can pay for itself in months, rather than being an afterthought. The decades of cheap copper and cheaper power have established bad habits and worse. “We’ve always done it that way”, more simply put, does not always work; and, it rarely if ever balances the budget.

Realizing Energy Savings    1 PDH

We added variable frequency drives for energy savings and it costs more to operate than ever before; the energy savings project is complete but there are no savings; the power bill is seriously over budget but there are no funds to upgrade the electrical system(s); we implemented a BNR process and our operating expenses have gone out of control; if these are familiar refrains, stop and pay attention to where the energy is going. Improper control logic with variable frequency drives and motors, improper wet well control, check valves, weir settings, lights and lighting are among the power mongers.

Remote Manual – Saving by Design    2 PDH

Why does the “Auto v. Manual” or more correctly, “Auto and Remote Manual v. Manual” come into a discussion of reliable process information and process integrity? The chemical, pharmaceutical, and a host of manufacturing industries long ago abandoned the concept and implementation of hard-wired manual operation. Bypassing the control system and the traceability of every action it offers simply cannot be tolerated in today’s safety conscious, litigious, efficiency conscious workplace. Further, for most real world processes, there are already more unknowns than there are equations to determine them; why add more unknowns into the mix? Why spend more to get a system that performs less well? The issues and economics from design through operation of process automation are presented with specific examples and case histories.

Anaerobic Digestion – Then and Now    2 PDH

Given a renewed focus upon energy conservation, the need for reduction of byproduct solids, “biosolids”, or sludge to satisfy several driving forces, and a continuing emphasis on cost reduction, anaerobic digestion has returned to the forefront of solids handling strategies for wastewater residual solids – the leftovers. These primary objectives, renewable energy generation, reduced solids, and reduced costs – capital, operating, or maintenance – are not at crossed purposes. Mitigating factors for consideration include the collection system, carbon to nitrogen ratios of the influent, effluent limits with respect to BNR, practical and operable ranges of sludge age in the main process train, and control strategies employed or to be employed. More gas generated equates to less remaining solids and more recovered energy; less remaining solids cost less for handling and disposal; and as it happens, the old dog anaerobic digestion has some old tricks to teach newcomers.

What Have We Forgotten? Decades Old Technologies for the Coming Decades    2 PDH

  • SRT control in anaerobic digestion. For all of the reasons wastewater processes use variations of the theme of a return “activated” sludge flow and a controlled waste activated sludge to optimize treatment, a similar process approach to anaerobic digestion was used to optimize gas production and solids reduction – why not use it again?
  • Breakpoint chlorination for ammonia removal. Ammonia-nitrogen can be removed by chlorination to reduce total nitrogen in the effluent, either as a back-up to process “excursions” or as a primary control process. Decades old technology and proven control strategies make this both economical and sustainable.
  • Equalization is always among the best methods of energy conservation. The affinity laws dictate that we avoid excessive speeds by rotating equipment to achieve maximum energy conservation. Equalization of flow, and loading if practical, is the simplest and usually most cost efficient solutions and need not require a major construction effort; in many cases, no construction need be required.
  • Lime softening for phosphorus control. Non-carbonate hardness components sulfate and phosphate are removed by lime softening processes with efficiency and low residuals determined by chloride and magnesium present. Just because it is wastewater the chemistry doesn’t change and using chemistry does not automatically imply the addition of chemicals.
  • Biogas cleaning without added chemicals. Hydrogen sulfide, carbon dioxide, and amines are hundreds of times more soluble in water than methane. Counter-current water washing is the original natural gas cleaning technology and still the most reliable and cost effective.
  • Facultative biology for real reductions in sludge quantities. More than a century of investigation has not changed the fact that facultative biology is more energy efficient than aerobic biology from the perspectives of lower oxygen requirements for a given rate of reaction and lower residual biomass production.
