Task 20 — Main Stream Process Screening Evaluation and Workshop
Objective. To evaluate the existing process and up to three alternatives for expansion of the main
stream processes at the Plant to meet proposed permit requirements and a design maximum
month flow rate of 14.2 mgd and to include preliminary sizing of options and development of rough
capital cost estimates for screening of alternatives; the screening to be conducted in a workshop
setting to reduce the number of main stream treatment alternatives for evaluation in conjunction
with add-on processes to one.
Approach
1. BC will use modeling to determine preliminary sizing of alternatives (presented in approach item 2) for
meeting the following requirements:
a. Maximum month flow and load capacity of 14.2 mgd as developed for the Sidestream N Removal
Evaluation project. Winter conditions will be evaluated, as these were found to be most restrictive
from Sidestream project.
b. Various combinations of effluent requirements, depending on the alternative, as developed and
reported in the Sidestream N Removal Evaluation project.
1. Evaluate the following proposed alternatives (including reasons why they are proposed):
a. Evaluate expansion of existing system as -is (AZO/Johannesburg), with expansion of process likely to
occur on City -owned property adjacent to existing Plant site ("back 40") due to site constraints.
b. Evaluate expansion of modified process configuration optimized for N and P removal such as the 5 -
Stage Bardenpho type process, with expansion of the process to be completed on "back 40"
(proposed as a conventional means of meeting stringent permit limits).
c. Evaluate short-cut N removal technology (nitritation to denitritation) (proposed as a potential means
of saving tank size and chemical cost versus conventional expansion).
d. Evaluate technology for N removal only, such as the MLE process, assuming year-round reclaimed
water discharge/groundwater percolation (proposed to eliminate need for P removal and stringent
ammonia limits as reclaimed water production is limited only by total N).
2. Produce rough (for screening purposes only) capital construction costs and basic operating costs
(chemical, aeration) for each alternative.
3. Produce draft TM of results of evaluations for City review.
4. Hold a workshop to discuss the results of the TM and reduce alternatives for evaluation to the best for
further screening with add-on processes. During this workshop, present the recommended add-on
Task Order 10460.F MERIDIAN UPGRADE ALTERNATICES ANALYSIS Page 2 of 7
BROWN & COLDWELL
alternatives (up to eight combinations of those listed in Task 30) to be evaluated in conjunction with the
recommended main stream treatment process.
5. Provide quality assurance/quality control (QA/QC) for all technical work (including memorandum).
City Responsibilities
1. Provide review and comments on draft TM (one round).
2. Provide review and comments on meeting minutes.
3. Participate in the review workshop, provide feedback.
Work Products
1. Electronic copy (in MS Word 2010) of the draft Main Stream Alternatives Screening Evaluation TM.
2. Electronic copy (in PDF) of the final Main Stream Alternatives Screening Evaluation TM.
3. Electronic copy of workshop meeting minutes, if deemed necessary by the City.
Task 30 — Add -On Processes Screening Evaluation
Objective. To evaluate up to eight add-on alternatives for expansion of the mainstream process
recommended from Task 20 and to include preliminary sizing of options and development of rough
capital cost estimates for screening of add-on alternatives; reduction of these alternatives to be
reduced to three for detailed evaluation in conjunction with the recommended main stream
process.
Approach
1. BC will use modeling to determine preliminary sizing of alternatives (presented in approach item 2) for
meeting the following requirements:
a. Maximum month flow and load capacity of 14.2 mgd as developed for the Sidestream N Removal
Evaluation project. Winter conditions will be evaluated, as these were found to be most restrictive
from Sidestream project.
b. Various combinations of effluent requirements, depending on the alternative, as developed and
reported in the Sidestream N Removal Evaluation project.
2. Evaluate up to eight combinations of the following proposed add-on alternatives in conjunction with the
selected main stream process from Task 20 (including reasons why they are proposed). The add-on
combinations to be evaluated will be discussed during the workshop from Task 20:
a. Tertiary chemical phosphorus removal process sizing and cost for tertiary membrane process to
remove phosphorus from -0.5 mg/L down to 0.07 mg/L. This option will be common to all other
options with the exception of MBR technology.
b. Tertiary nitrification process (likely biological aerated filter) and denitrification filters (proposed as
means to reduce level of nitrification in the main process and eliminate the need to denitrify in the
existing tankage).
c. Add influent flow equalization to existing system in conjunction with sidestream treatment (proposed
to improve nitrification performance and reduce size of system expansion).
d. Add additional centrate load equalization in conjunction with sidestream treatment (proposed to
improve nitrification and performance and reduce size of system expansion).
e. Use Biomag in conjunction with existing system (proposed to reduce footprint of expansion by
allowing for higher operating MLSS and SRT).
f. Use MBR technology to reduce footprint and to reduce need for tertiary phosphorus removal
system.
g. Confirm that the IFAS technology in the configuration proposed in the facility plan is still a viable
alternative.
