The population growth in India is immense. Accordingly, the water supply amount is enormous which,
in return generates large amounts of wastewater. One such region is the Palghar Boisar region whose population
growth according to calculations will sky rocket. But the amount of sewage treatment plants present is only one for
a particular area. So, to combat this we decided to construct another Sewage treatment plant per another area. In
this project we will discuss the population growth of the region, design parameters, the method selection for
design, introduction and the complete design of a sewage treatment plant for Tarapur MIDC. The treatment
procedure has been developed to treat sewage and reuse the water for various purposes like water to gardening,

Solid waste management (SWM) is one of the major environmental issues in cities of many
developing countries, including Nepal. Urbanization, Industrialization and economic
development has led to increasing generation of municipal solid waste (MSW). The use of
products that generate hazardous waste is another concern. Unmanaged disposal of medical
wastes from hospitals and clinics also contribute to pollution and public health hazards in the
localities. Therefore, SWM has become a major concern for the municipalities of Nepal. The
total sample size of 21 from the households, Restaurants, Hotels, commercial shops (including
Fruit shop, Barber shop, Spectacle shop, Library, Book shop etc.) were collected around
Kathmandu municipality.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

5. Introduction
• A trickling filter is a type of wastewater treatment system.
• A trickling filter , also called trickling biofilter, biofilter, biological filter and biological trickling filter , is a fixed-bed, biological
reactor that operates under (mostly) aerobic conditions.
• Trickling filters are conventional aerobic biological wastewater treatment units, such as active sludge systems or rotating biological
contactors.
• Trickling filters are a secondary treatment after a primary setting process (see also septic tanks or pre treatment).
• Trickling filter process can define as the biological system, which tends to separate or degrade the maximum organic and inorganic
waste (up to 85%) out of the primary or raw sludge via the slime layer.
6. Principle:
• Pre-settled wastewater is continuously ‘trickled’ or sprayed over the filter. As the water migrates through the pores of the filter, organics
are aerobically degraded by the biofilm covering the filter material.

8. Bar Racks :A rough screening device, eith
er vertical or inclined, with parallel bars s
paced 3 inches apart, placed in a wastew
ater collection pipe or other waterway to
catch debris. The screenings may be raked
from it.
10. 1.Filter bed: It is a bed chiefly containing crushed rock or other coarse media.
The construction of a filter bed is roughly 6 feet deep and 200 feet in thickness.
Settled sewage is flushed evenly over the filter bed containing organic and
inorganic waste via continuously rotating distributor’s arm. Holes within the
rotary distributor arm facilitates the trickling of primary influent and settled
sewage throughout the filter bed.
2.Microbial film: Within the filter media some aerobic microbes are found on the
surface, and some anaerobic microorganisms are found below the filter media.
As the wastewater trickles downward, the microorganisms associated with the
filter media starts utilizing the organic matter of the wastewater and forms a
later called microbial slime. Thus, the microorganisms in the filter media play a
pivotal role in degrading the organic matter in the sewage, thereby minimizes
BOD and COD from the sewage.
11. Drainage system: The treated wastewater from the trickling filter bed
goes down the drainage system and further undergoes tertiary
treatment via membrane filter and disinfection before secondary
sedimentation. A secondary clarifier is a sedimentation unit, which
separates the small colloids, suspended particles etc. at the bottom out
of waste fluid.
Besides, the tertiary treatment is also necessary for the safe disposal of
the effluent, as this step eliminates the pathogenic microorganisms. In
contrast, the oxidized or decomposed organic matter sloughed down
and recycled back in the trickling filter mediated via return pump.
12. Types of Trickling Filters:
Depending upon the hydraulic and organic shock load, trickling filters can be categorized into two types,
namely high rate and Standard rate trickling filter. The hydraulic loading rate can define as the sewa
ge flow (Q) per unit volume (V) of filter bed in a day, while the organic loading rate can define as the kil
ograms of BOD (Y5) introduced into the per unit volume (V) in a day.
1.The BOD removal efficiency of both standard and high rate trickling filter is about 75 to 90%. The nitrif
ication of the primary effluent is relatively higher in standard rate filters, whereas high rate trickling filters
produce partially nitrified effluent.
2.Standard rate and high rate trickling filter are suitable for the treatment of low to high strength domestic
wastewaters and industrial wastewater.
Recirculation of the effluent is not provided in the Standard rate filters. In contrast, high rate filters are
provided with return pump between the trickling filter tank and secondary clarifier that aids in efflu
ent recirculation.
To identify the characteristic difference between the two, one can look upon the table given below t
hat specifies the efficiency and depth of the standardand high rate trickling filter. Recirculation ratio
is recirculation discharge upon incoming discharge.
13. Properties
Standard rate trickling
filter (SRTF)
High rate trickling
filter(HRTF)
Hydraulic loading 1-4 m3/m2.d 10-40 m3/m2.d
Organic loading 0.08-0.32 kg BOD/m3.d 0.32-1.0 kg BOD/m3.d
Depth 1.8-3.0 m 0.9-2.5 m
Recirculation ratio 0 0.5-3.0- domestic
wastewater
8- strong industrial
wastewater
14. Advantage and Disadvantage:
Advantages:
1. Can be operated at a range of organic and hydraulic loading rates
2. High effluent quality in terms of BOD and suspended solids removal; in com
bination with a primary and tertiary treatment also in terms of pathogens
3. It is a simple and reliable secondary treatment unit of the wastewater.
4. It can be used to degrade a variety of organic waste.
5. Trickling filter can resist shock loadings.
6. It efficiently oxidizes the ammonia or efficient in ammonium oxidation.
7. Trickling filter aids to produce effluent free of BOD, COD, nutrients, suspend
ed colloids etc.
8. Its construction requires a small land area, unlike constructed wetland.
Disadvantages:
1. Its designing requires high capital costs.
2. The designing of a trickling filter requires expert skills.
3. Its operation and maintenance require regular attention by the skilled
labour personnel.
4. The trickling filter process is a continuous process, which needs an
uninterrupted supply of electricity and wastewater distribution.
5. It sometimes causes flies breeding and odour problem.
6. The effluent produced by the trickling filter needs to treated further by
the chemical disinfectants.
7. Accumulation of excessive biomass may cause clogging of the TF-unit.
8. Not all parts and materials may be locally available.
15. Conclusion:
Therefore, we can conclude that the trickling filter process is one of the attached growth system, which means that the microorgani
sms responsible for the degradation of the organic matter are attached to the non-submerged packing material. It is designed for th
e secondary treatment of the primary influent to eliminate the suspended and soluble organic waste along with the nutrients.
