Aiming better gsm controls a possible approachDevesh Singhal
The document discusses improving control of grammage (GSM) in paper machines by modifying the approach flow system. Currently, variations in GSM occur when the secondary screen reject valve opens only briefly. The document proposes removing the secondary screen and installing a screw pump with a variable frequency drive-controlled motor after the main screen to continuously throttle the reject flow at a low level. This proposed system could eliminate GSM variations and fluctuations in the cross-machine profile while also providing energy savings by removing the secondary screen and reducing throughput needs.
Stack height often surprises me. Can we consider cutting short stacks of factories to reduce pollution, as the polluter would be faced to get into self compliance, willingly or unwillingly. Think.
Can we provide some space for viruses in our lives? A different thought, indicating what can be done to to live happily without a fear of virus and let it live its life.
Delhi-NCR air is becoming more and more polluted. We need to find a solution, that too very fast. The present concept note presents such a simple idea to solve the pollution problem.
When environment protection causes problemsDevesh Singhal
What happens when an industry starts treating effluent to achieve better and better than mandated norms? This is done by additional energy, capital cost and thus creates undesirable problems.

This document provides a concise summary of paper and the paper industry for students. It discusses the history of paper and how the paper making process has modernized. It also summarizes key facts about the paper industry in India, including production levels, recycling rates, and environmental practices. The document aims to enhance students' knowledge about paper and debunk common misconceptions.
The document discusses voltage fluctuations that can cause electrical motors and appliances to trip. It describes how fluctuations can originate from the power supply or internal wiring issues. Methods are presented to identify weak neutrals, measure fluctuation magnitude, and reduce tripping, such as installing a supervisory neutral bus or changing control power phases. The goal is to better understand fluctuations and minimize their impacts on production.
The document discusses the issue of plastic pollution and proposes solutions. It notes that plastics are a major source of pollution as most are not recycled. While plastics are very prevalent in modern life, the key issue is plastic waste management rather than plastics themselves. The paper industry could help by recycling products like paper cups and tetra packs that contain a high percentage of paper along with some plastic. This would remove plastic waste from the environment by collecting it along with recycled paper. Mandating that laminated packaging contain at least 75% paper would enable efficient recycling and reduce plastic pollution.
The document discusses rethinking the use of approach flow screening on paper machines. It notes that removing centrifugal cleaners from approach flow 10 years ago resulted in dramatic energy savings, improved basis weight control, reduced web breaks by over 75%, better steam control, and increased yield. The document observes temporary 0.5-0.7 gsm reductions in basis weight from the timer-operated reject valve on the current pressure screen and slot screen system. It questions whether the electricity costs and basis weight control problems from the approach screen outweigh its benefits as a "security guard" and suggests starting to think about removing approach screens.
This document discusses how hair care products are a major source of pollution that is often overlooked. It notes that the water and chemicals used in shampoos, conditioners, dyes, and other hair products exceed the pollution produced by most major industries when considered globally. The author argues that wearing hats more often could help reduce this pollution by decreasing the need for frequent hair washing and product use. Wearing a hat for a month is proposed as a task people should accept to help raise awareness of hair care's environmental impact and potential solutions like cutting one's hair short.
Have you faced problems of incorrect readings in displays, flickering of tubelights etc. Do you know, electrical pollution can be harmful for our lives also?
The document proposes a concept to help reduce smog levels in Delhi using controlled artificial rain. It suggests installing vertical conical tunnels equipped with fans, pipes with shower nozzles, and water collection tanks. The tunnels would suck in polluted air from the bottom, spray it with water droplets of different sizes to "wash" the particulates, and expel cleaner air from the top. Initial trials could be conducted near polluted areas to monitor effectiveness. The author believes cooling tower manufacturers could build these units, which would cost less than 2 lakhs each and treat 1 million cubic meters of air daily. Feedback on this approach is requested.
Lowering stack heights from industrial units would help better control air pollution in three key ways:
1) Pollutants would remain closer to the ground and immediately impact workers, managers, and neighbors, forcing units to take action to reduce pollution.
2) Lower stacks would make pollution monitoring and enforcement easier by allowing for ambient air sampling close to ground level near units.
3) Alternative pollution control methods like fine bubble diffusers in water tanks could more efficiently trap pollutants from lower stacks compared to existing wet scrubbers. Cutting stack heights may enable exploration of better control technologies.
"Save Paper, Save Trees" You must have seen such slogans often. Paper industry is generally targeted as a polluter, and the aim of this presentation to clear some myths.
Yankee paper machine MG cylinder stress relieving has been reviewed, specially for the mechanical engineering students. Hope this will improve their thinking, analysis and evaluating capabilities.
The document discusses a meeting that took place. It describes the attendees and some of the topics that were discussed, including progress that has been made and future plans. Names and details are abbreviated to maintain confidentiality.

Think. Taste.
या आलू का परांठा दूषण फै लाता है?
जरा सो चये,
आलू का परांठा,
तवे पे पड़कर,
घी म डूबकर,
तला सा जाता.
घी क खुशबू,
गम! म तपकर,
आटे से #मलकर,
तवे पर जलकर,
नथुन& म भर जाती.
रसोई गवाह है,
उस धुएं क ,
रसोई क द/वार,
सहमी सी ह0,
अपने ऊपर लगे
दाग& से सकु चाती .
आभार,
उस चमनी का
जो इस धुंए को
रसोई से बाहर है करती,
जले चाहे पड़ोसन,
कु ढ़े चाहे पडोसी.
मौन ह0 सरकार,
मौन है जनता,
सद6 के मौसम म,
आलू का परांठा ह/,
हर रसोई म बनता.
और 8फर,
जब भी सद6 आती,
:द;ल/ का <दूषण बढ़ जाता.
हर सद6 म,
म0 सोच म पड़ जाता..
?या वाकई,
आलू का परांठा,
<दूषण है फै लाता?
Can our cooking create

that is the reason that

The matter has been
prepared on a funny
note, and there is no
intention to go against
this delicious foodstuff.
However, it is requested
from food technologists
to develop preparing
guidelines so that ‘Aloo
Paranthas’ can be
prepared with less
pollution.
