Rain Garden Design Criteria

Criteria




Must be at least 10 feet
from building
Garden should optimize
backyard drainage
Must have outlet for rain
garden overflow
Size of garden should be a
certain proportion of the
roof area needing to be
drained

depends on soil type and
roof area needing to be
drained
Roof section which drains to backyard

Discharge Calculations


Assumed laminar, incompressible fluid
Bernoulli’s Eqn. – used to calculate velocity in pipe
V = velocity in ft/s
p = pressure (psf)
g = force of gravity (ft/s^2)
ρ = specific gravity
z = elevation (ft)

Manning’s Eqn.– used to calculate fluid velocity in open channel
n = surface roughness coefficient
R = hydraulic radius (ft)
S = slope of energy line º slope of bed
V = velocity (ft/sec)

Discharge Eqn. – used velocity to find discharge
V = velocity (ft/s)
A = area (ft^2)
Q = VA

Rain Barrel

Why use a rain barrel?



Increase water-holding capacity
Environmentally friendly way
to use water
Water storage for use during
dry periods during summer



60 gal would provide .85 in, or
53.3% of available water to
plants
60 gal costs $0.15, however
customer would like the barrel
Possible problem: mosquitoes

Wastewater Treatment Plant Need


Sustainability of the digester project at West
Lafayette Waste Treatment Facility.
Goals




To reduce operating cost of WWTP
To decrease quantity of waste to recycle
To increase methane production
To maximize usage of available capacity of renovated
digesters
3
Bio-Energy
Goals of the project

To help the community become more green by:


Reducing quantity of Purdue waste food currently
going to landfills
Identify additional sources of waste food substances
for the digestion process

Background Research



Researching a replacement to the activated
carbon, silica gel is currently being looked at.
Toured dining facilities to better understand
current waste food collection and treatment
methods
Research other potential waste food providers

Possible contribution in tons
6
Bio-Energy
Background Research


Currently using 500 lb. activated carbon at
approximately $2,000 per cycle which is
approximately two to three months
Silica gel as a new media for filtering the biogas


Silica gel is a cheaper chemical and can be made at
WWTP
Need to determine the best chemical form and
composition of the silica gel for the biogas filtration
7
Bio-Energy
Alternative Research Ideas

Improving function of digester by adding other
microorganisms.


Removal of siloxanes from biogas with biofiltration
via Pseudomonas
Boost in methane production from Lactobacillus

Future Plans



Continue to explore potential waste food
providers
Recommend replacement technology for carbon
treatment facilities
Work with WWTP to integrate team’s proposals
into current operations
10
Bio-Energy
Statistics

Purdue is giving 5 tons of pulp per week


This adds up to an annual savings of $10,000 in
landfill costs, reduced labor, and fuel savings
West Lafayette Waste Water Treatment Facility

This added food saves them annually $4,000 in
electricity and natural gas savings.
11
Budget


Bio-Energy
Our current budget is small due to the heavy
research being done at this phase
Considerations were made to purchasing silica
beads. However, after a meeting with Dr. Michael
Harris, Assistant Dean of Engineering, we
realized that we could produce the silica gel
ourselves
