ASSESSMENT OF WASTE WATER TREATMENT IN CANAANLAND, OTA, OGUN STATE, NIGERIA.O...Felix Oginni
Effluent from a sewage treatment plant in Covenant University, Canaanland is made to pass through a series of constructed wetland before discharging into a gully that drains into River Iju (also known as Atuara). This river is used as a source of drinking water and also provides food in form of fish for hundreds of thousands of people downstream and eventually enters the lagoon, some 60km away. Effectiveness and adequacy of the wastewater treatment facility in place was assessed in order to improve sanitation within this watershed, thereby alleviating environmental challenges in this coastal region of Nigeria. Waste water is gravity drained to the southwest portion of the campus where the solid is removed and the liquid is allowed to flow through six sets of constructed wetlands, each with four chambers. Within each chamber are water hyacinth plants put in place to remove nutrients from the waster water.
A quick survey of the facility shows the system to be effective in reducing and removing solids and dissolved solids from the waste water. The pH ranged between 6.6 and 6.8, conductivity from 530 to 600, and total dissolved solids (TDS) ranged from 360 – 400 ppm. The data obtained indicate that some modifications need to be made as the waste water treatment system is not very efficient in reducing the amount of TDS and nutrients. The flow rate is considered to be very high from cell to cell, thereby not allowing time for the plants and microbes to reduce the TDS. It is suggested that some method be devised to slow down the flow rate to allow the plants and microbes to work on reducing the TDS. Parameters also also considered included DO, E. Coli. Nitrate and Phosphates.

A new world wildfires -2021111 for postingJim Dodenhoff
Abstract
From 2018 through 2021, Wildfires have emerged as one of the most destructive and deadly forces impacting energy resiliency around the globe. Dramatic new policy measures have been implemented in different jurisdictions with decidedly mixed results. Even less clear is whether these policy measures will truly ensure safe, reliable, and affordable energy------along with a modicum of reliability. This presentation will provide a detailed overview of the costs of wildfires within a resiliency framework, focusing upon California, Australia and other highly impacted geographic areas. Existing policy responses such as the Public Safety Power Shutoff (PSPS) program in California will be evaluated for efficacy. Evolving policies will also be reviewed----especially those that hold material potential to mitigate risk. Finally, for those areas with high wildfire risk, electricity market responses in the commercial and industrial (C&I) sector will be explored in detail. To what degree has wildfire risk expedited the shift from centralized utility electricity generation to distributed and/or third-party C&I electricity generation? Has this shift focused upon specific technologies (i.e. storage vs renewables vs fossil fuel generators). The presentation will assess
whether these market shifts are mitigating wildfire risks or simply creating greater complexity and variability.
How Changes to Time of Use (TOU) Rates are Impacting Commercial & Industrial ...Jim Dodenhoff
The significant penetration of solar energy in the electricity supply mix, especially in Western U.S. states, has resulted in profound changes to the shape of electricity system load curves. In the past, utility electricity suppliers with summer peak demand generally found their load peaking from mid-day to late afternoon. These same geographic areas have also been the most attractive candidates for solar implementation. The net effect has been a shifting of system net daily peak period to later in the day: spanning mid-late afternoon to early-late evening.
A guiding principle behind most ratemaking is to have electricity rates reflect real-time system costs. This provides higher pricing signals to the customer when the system has less available supply of electricity. Many utility tariffs are now either incorporating Time-of-Use (TOU) tariffs and/or moving their peak periods to later in the day to more accurately reflect net system peak and the impact of significant solar supply. These changes can have large cost impacts on Commercial & Industrial end users who have significant load in the evening hours.
This presentation will model these TOU tariff changes in California and other Western geographic areas. Energy management technologies such as energy storage and advanced controls will be analyzed as potential solutions to mitigate increased costs from TOU tariffs.
Finally, the carbon-intensity of unique utility electricity grids will be analyzed in the context of TOU peak periods. The author will present findings showing whether purchase of utility electricity during daily peak periods buys into a higher carbon emitting generation fleet, and to what degree.
In the first 15 years of the 21st Century there has been a steady growth in Microgrids driven by a number of factors including geography, resilience, and location specific economics. In the last five years this growth has accelerated as the cost of renewables and storage have dropped significantly allowing for integration of these distributed energy resources (DER's) into Microgrids. A key to this trend has been intelligent, cybersecure microgrid control solutions (MCS) which have algorithms that can execute sophisticated control strategies that manage power flows safely and optimally. It is the MCS which is the nervous system of the microgrid and the platform upon which Microgrids are becoming a mainstream and scalable energy solution.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

Let’s see WWTP’s as the Resource
Centers that they are!
Our past research focused broadly on the Water Energy Nexus-----with particular focus on the linkage between energy conservation and water conservation measures at Water Distribution facilities.
We also noted that the Water-Energy Nexus quickly becomes a three-legged stool as it is virtually impossible to discuss water without also discussing food.
In California, agriculture comprises X% of overall water consumption. In Arizona, agriculture comprises Y% of the overall water consumption.
Over the past 3 decades, water conservation and energy efficiency have been concurrently operating at achieving their specific goals while symbiotically achieving the goals of the other.
Water Savings = Energy Savings and
Energy Savings = Water Savings
This schematic demonstrates the interplay of water flows and energy flows. (Blue Arrows Water, Red Arrow Energy)
EPA estimates 3-4 percent of national electricity consumption, equivalent to approximately 56 billion kilowatts (kW), or $4 billion, is used in providing drinking water and wastewater services each year.
-Water and wastewater utilities are typically the largest consumers of energy in municipalities, often accounting for 30-40 percent of total energy consumed.
Our initial research focused on Water Distribution Systems, and what we determined was that a Systems Approach was critical to understanding Water Distribution Systems and that the greatest opportunity for energy-water savings was in conveyance of supply and distribution of of treated water to end uses.
Today’s presentation focuses broadly on Wastewater Treatment and the opportunities for Energy and Water Conservation. We also take a peek at the importance of factoring in the beneficial use of treated wastewater.
At a high level, Wastewater Treatment has three primary objectives
Remove pathogens that could be dangerous to drinking water
Remove Nutrients (namely Phosphorus and Nitrogen) that could result in algae accumulation
Remove organics that contribute to low dissolved oxygen levels in water
Pause at the Primary, Secondary, Tertiary Graphic……….
This type of process, which is the most widely used in the industry, has many mechanical elementss: Pumps, mechanical aerators, blowers, diffusers, compressors, filters, and tanks. It also speaks to a paradigm where “dirty wastewater’ is “treated” primarily through addition of “cleaning chemicals” to “remove” the bad stuff and bad smells…..with the end product being cleaned water and “sludge” which might require additional treatment…………a Wastewater Treatment Plant. We’ll come back to this “old paradigm”.
*From EPA-This is # of Facilities that treat domestic wastewater from residential and commercial establishments
…..an additional 500+in older cities and major urban areas collect rainwater in the same pipes as domestic wastewater
15,000 + WWTP facilities in the U.S.*
Total flow of 33,000 MM Gallons/day
Serve 75% of U.S. Population
Vast Majority of WWTP’s publicly owned
WWTP Electricity Use 1-2% of Total U.S. consumption
Energy Use can range from 20-40% of the overall cost to operate a WWTP
WWTP Energy Costs key driver for muni/county budgets----a potential “budget breaker”
-Provide a brief overview of each Major Technology
-Note differences in Energy Intensity
40 CFR Part 503 for Biosolids………..(also applicable to algae solids from Wastewater Treatment)
-Minimum national requirements applicable to the use/disposal of sewage sludge
-Part 503 includes, for Class A and Class B
-Sewage Sludge quality limits
- Management practice requirements
-Monitoring/Recordkeeping/Reporting Requirements
-Additional State, local requirements
--Applicable to algae solids from Wastewater
“Typical” Energy Use Daily Cycle for WWTP roughly corresponds to timing of water use, although there can be delays based upon the distance between the collection system and the WWTP.
Notable that Energy Load Profile for WWTP doesn’t necessarily correspond to energy profile of utility….might be interesting to have an overlay slide which I’ll pull together.

Broader Use of Biotreatment Wastewater processing-While Biotreatment cannot be used everywhere all of the time, it certainly can be used to a greater degree to execute upon targeted processes at existing and new WWTP’s. Has inertia set in with Activated Sludge technology?
Increased adoption of on-site renewables, storage, and combined heat and power (CHP) modules. They bring many benefits to WWTP’s inclusive of lower EUI, greater resource recovery, and enhanced local control
Environmental Regulatory Policy that recognizes biogas, biofuels, and algae products as renewables. In some cases environmental policy, incentive programs, tax credits don’t recognize resources recoverable from WWTP’s as being renewable. This is a cognitive distortion that should be remedied to help level the playing field for these resources---taking into account proportional GHG impacts.
Greater Beneficial Use of Treated Wastewater-All “clean” wastewater is not equal. That which provides a beneficial use is making greater use of the resources required to “make it”----all things being equal.
International Technology Transfer-WWTP in the U.S. is generally accepted as a mandatory public service, and we’ve grown accustomed to having this service available in virtually all of the U.S.---on a reliable basis. Not so for much of the rest of the world---especially in developing countries. As it turns outs, the recommendations we offer are uniquely suited to addressing stand-alone or remote WWTP requirements in developing countries. We have a unique opportunity to provide technology transfer along a declining cost curve to nations which currently do not treat their sewage.
Only 8% of Wastewater Treated in Low Income Countries, vs 70% in high income countries
Latin America, Asia, and Africa wastewater pollution impacts 1/3 of rivers
Water stress occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use. Water stress causes deterioration of freshwater resources in terms of quantity (aquifer over-exploitation, dry rivers, etc.)
