The debate has been accentuated by a comparison of these graduates to those from baccalaureate civil engineering programs accredited by ABET's Engineering Accreditation Commission (EAC). This comparison has become more intense with the establishment of the "Body of Knowledge" for civil engineering and the "Raise the Bar" initiative for professional licensure, with the associated BS + 30 requirement for licensure eligibility. ABET itself distinguishes between "technologists" who graduate from ABET/ETAC accredited baccalaureate programs and "engineers" who graduate from ABET/EAC programs.

However, utilization of green walls as an aqueous treatment option has been primarily limited to grey water. This study evaluates select media as appropriate support for plants and microorganisms in a novel green wall system used to treat wastewater from craft and micro-breweries. The media must have hydraulic capacity to treat large volumes of brewery wastewater, be lightweight and commercially available, and provide structure for plant roots and biofilm development. Two expanded recycled glass aggregates (Growstone® and Poraver®) and a lightweight expanded clay aggregate (Hydroton®) were evaluated, having a d50 range from 6 to 12 mm. To assess media performance, this study determined hydraulic characteristics and evaluated the growth of leafy green plants and microorganism populations irrigated with 100% raw brewery wastewater. It was determined that media with a particle d50 = 12 mm would facilitate a hydraulic loading rate of 1623 m3/m2/day media under unsaturated conditions and not result in interstitial velocities that shear away biofilm. No significant difference in plant growth metrics, microorganism type or cell density were observed between media. There were nearly three orders of magnitude more bacteria colonies than yeast CFU in biofilm. This innovative application of green walls has the potential to provide manufacturers of fermented beverages with a treatment option that has a low capital cost, simple to operate, and a small footprint, thereby avoiding traditional treatment processes and/or high sewer use fees.

The objective of this study is to evaluate the effectiveness of using green walls to pretreat wastewater generated by small to medium sized food and beverage manufacturers. A 1.2 m high green wall was constructed using two, 610 mm×610 mm panels filled with recycled glass media and planted with Epipremnum aureum. Brewery wastewater was recirculated through the system under four experimental scenarios: media, only; media with biofilm; media with plants; and media with plants and biofilm. Reduction of BOD was at least 65% after 24 hours in all four scenarios. Removal of turbidity, BOD, and total nitrogen was similar in scenarios involving biofilm with or without plants. Green walls appear to offer a space and cost efficient method for pre-treating wastewater generated by beverage and food industries.

To this end, four different types of bed surface conditions (impermeable smooth bed, impermeable rough bed, permeable sand bed and impermeable distributed roughness) and two different Reynolds number (Re h = 47,500 and 31,000) were adopted in the study. Sand particles of median diameter of 2.46 mm were used to create the roughness. The results show that the mean velocities collapsed well for different Reynolds number and for all different bed surfaces. The maximum velocity for all flow conditions were observed below some distances from the free surface. The location of maximum velocity is seen to be dependent on both of roughness and Reynolds number. The smooth bed test data agrees well with the standard log law and collapses well in viscous sub layer and overlap region. The extent of collapses is found to be dependent on Reynolds number. Friction coefficient is noted to be dependent on both the Reynolds number and roughness.

This research evaluated the suitability of green wall plants for the preliminary treatment of wastewater generated by food and beverage makers, quantifying suitability with plant growth metrics. Edible micro-green, ornamental, and legume plants were planted in perlite filled pots and irrigated continuously with untreated brewery wastewater or a control of Hoaglands solution. Plants receiving wastewater had less growth than the control. Stem growth for microgreen and legume plants that were started from seed was 798% and 253% less, respectively, when irrigated with 100% brewery wastewater. The stem growth of established ornamental plants was 26% less when irrigated with the wastewater. Wastewater irrigated plants with the highest rates of growth and survivability included the mustard plant (Brassica juncea), and ornamental plants Epipremnum aureum (Golden Pothos) and Chlorophytum comosum (Spider Plant). Growth metrics for wastewater irrigated legumes were higher for plants inoculated with rhizobia, than plants without the inoculation, which suggests low available nitrogen concentrations, rather than toxicity of the wastewater, limited plant growth. The results suggest that ornamental plants such as Epipremnum aureum and Chlorophytum comosum can be sustained, without the addition of supplemental nutrients, in a green wall utilized to treat brewery wastewater.

This paper will present one approach to developing and managing a successful on-line learning experience for students. Successful on-line courses include the following 5 elements: “know” your students; realize that your primary role is facilitating learning by management, not teaching; use various media for sharing information with the students; use multiple grading opportunities and types; and be responsive be very responsive to student’s questions. The proof that this approach is successful is five years of student comments through formal course evaluations and informal e-mails of appreciation. I believe this approach can be applied to traditional on-campus courses, as well. Index Terms – pedagogy, on-line, distance learning, CIEC, Wolcott
