Karachi to have 3 desalination plans; one to be acquired from KANUPP

on 25/01/2023

In a huddle on development projects of the province, the Sindh government has decided to provide two desalination plants to Karachi that would make available a total of 10 MGD sweetwater to the capital. Also, a seawater desalination plant abandoned at KANUPP will be acquired by the government.
The decision was made Keeping in view the water needs of the metropolis especially in old town areas of the city.
In the moot, whose official communication was released to the media, the Chief Minister of Sindh Syed Murad Ali Shah decided to install two new Seawater Desalination plants, each one of 5 MGD, in the metropolis. He also aims to acquire a seawater desalination plant abandoned at KANUPP.
The chief minister said: This will help to provide drinking water to the people living in old areas of the city to the DHA,”.
The meeting, held at the CM House in Karachi. was attended by provincial ministers, advisors, secretaries and other relevant officers.
During briefing regarding the 5-MGD Seawater Desalination Project, the CM was informed that water requirement stood at 12,00 MGD against which 655 MGD was being provided showing a shortfall of 535 MD.
“KWSB has prepared a scheme to set up a Seawater Desalination Plant (SWDSP) of five MGD capacity to supply water to the users in district South,” provincial minister Nasir Shah said, according to the statement released by the CM House.
Three locations including Ibrahim Hyderi, Ayesha Masjid DHA-VII, and the Village Restaurant at Sea View were proposed for the installation of desalination plants. The CM approved Ibrahim Hyderi at Korangi Creek which is one-and-a-half kilometres away from Dhari Island.
The intake from this location would supply water to the Ghazi Pumping Station via Coast Guard Chowrangi where another pumping facility is available as a backup in case of a failure or other emergent circumstances at Ghazi Pumping Station.
The chief minister directed the local government department to install another 5-MGD desalination plant near Lyari so that the area could be provided water from there. He also directed the provincial minister Nasir Shah to talk to a private firm to provide water to KANUPP. The private firm in question had installed a 1.2 MGD desalination plant. KANUPP installed its own plant in the past, which now remains abandoned, and could be used to provide water to the city.
In the meeting, CM Sindh also approved the construction of the Korangi Causeway bridge. Minister Shah set the timeline for the bridge and directed his department to complete a detailed design by August 31. He also directed the department to finalise formalities and start construction by November 1.
Earlier, the bridge was proposed to be constructed under PPP mode but now it would be an ADP scheme of Rs5 billion.
CM Murad, during the meeting, was also briefed that the additional 65 MGD water would be brought through Haleji Lake to Pipri via an integrated system of Canal, Conduit, Pipeline, Pumping Station and other necessary ancillary works.
CM Sindh directed the relevant ministry to restart works proposed including four other packages and asked to prioritise the construction of RCC lined Canal and RCC Conduits from Haleji Lake to Gharo Pumping station, including the construction of intake structure at Haleji Lake and Keenjhar Gujjo Canal; construction of new 65 MGD Pumping Station, including Mechanical & Electrical, works at Gharo; and laying of 72-inch dia MS Rising Main from new proposed Pumping Station at Gharo to Forebay, including the construction of new Forebay Chamber at a high point.
The CM also directed to begin the Hub Canal overhauling project and asked the local government department to remove all issues regarding the

Innovations in Healthcare
Pakistani engineering, tech companies can make miracles

on 25/01/2023

Pakistan’s two top-notch companies and an engineering regulatory body emerged on the same page in a moot in the federal capital that the joint effort of the country’s industry can make miracles in terms of local manufacturing of engineering products that swallow billions of dollars through their import.
The Alsons Group of Industries, a leading industrial group in Pakistan, and Systems Limited, a known IT company seemed to agree to launch a joint effort for innovation and local production of medical devices and the support system in the field of the healthcare system. The Pakistan Engineering Council (PEC) assured them of its complete support at every step.
The moot titled ‘Innovations in Healthcare’ was organized by The Innovation & Entrepreneurship Committee (I&EE), Pakistan Engineering Council (PEC) in a local hotel.
Alsons Group of Industries, a leading industrial group in Pakistan collaborated in the event, sponsored by Systems Limited, the premier technology organization in Pakistan, with a track record of over 45 years of providing successful solutions to complex business problems under digital, data, cloud and business traveled process outsourcing.
The guest speaker David J. Howard, is a known medical professor, and technologist to Pakistan from the UK.
Engr. Najeeb Haroon said Pakistan needs a lot to be done and he appreciated Dr. Howard’s initiative to travel to Pakistan at his own expense. ‘I assure you that PEC will continue to support innovative initiatives, he added.
Mr. Howard gave a detailed presentation on the latest innovations in medical sciences, biomedical engineering, and devices.
He also shared his global experience as regards new needs and requirements in the field of health care systems in developing countries.
He was of the view that Pakistan has an enormous potential in healthcare. Why? Because he said you are in the land of the greatest civilization and lessons are to be learned from history.
He talked about how the joint effort of the people from different fields, governments, engineers, physicists, chemists, doctors, etc. made possible medical equipment and devices in human history.
People even call innovators mad and later their inventions were widely used. He gave an example of Dr. Archie Brain who was called mad but his invention Laryngeal Mask was being used up to 56 percent by 2018 by anesthetists.
He talked about new ideas and old ones reworked saying we should see the pst for the future.
Only wealthy countries have sufficient ventilators, which are highly sophisticated. He asked if there was a treatment method for both wealthy and poor people.
Yes, negative pressure breathing support devices were first designed in the 19th century. They are much safer and more effective than modern positive pressure ventilators. The Alsons Group, he said made one small and efficient device called Allno Ventura.
He had his reasons why Exovent is efficient as he said it did not need oxygen.
He said the main requirement of the future is that the present and next generation of doctors should keep an open mind to research and reintroduce negative pressure respiratory support alongside positive pressure devices. ‘We need to develop both, each has its advantages and disadvantages. We need systems to treat respiratory disease in every country.
Chairman, Alsons Group Abdul Rehman Allana
shared his experience of how his industry started manufacturing biomedical devices and became the very first Pakistani company to produce locally manufactured devices.
He dwelt upon the history of Alsons and what it had been producing. We are very focused on our goals and the epicenter is Pakistan, contributing to the national effort.
‘We are ready for mass production of ventilators after DRAP approvals.
He said the efforts are also on to making Exovent, a negative pressure respiratory machine. ‘I think we shall develop negative pressure device while many other countries are also doing it.
He says Pakistan needs a lot of companies on board, together they can make locally made products and export things worth billions of dollars as we have every advantage which we should use in the medical field.
Mr. Ashraf ul Kabir, Senior Vice President, Engineering highlighted the market and technology trends present in the healthcare sector and the contributions done by Systems Limited in terms of expertise and solutions to healthcare clients globally. “Systems Limited is working tremendously and in-depth in the healthcare sector by leveraging data in each stage of the whole pharma process using data analytics,” said Mr. Ashraf ul Kabir.
Dr. Bhawany Shankar Chaudhry said in his welcome address said David J. Howard will take the moot in the history of innovations. He told the moot about the background of how this program became a reality. ‘We believe it is the most relevant program in terms of biomedical engineering, producing devices and products for our healthcare systems.
The moot was participated by Secretary Planning & Development, Special Secretary Health, CEO Ignite, officials from DRAP, professors from NUST and other engineering, universities, NESCOM, doctors, and medical technologists. n

Phenomena of Electron Ionization

on 19/01/2023

This procedure is thought of as a hard high discontinuity ionization strategy since it utilizes exceptionally vigorous electrons to deliver particles. This prompts broad fracture, which can be useful for structure assurance of obscure mixtures. Electron Ionization is the most valuable for natural mixtures which have a sub-atomic load under 600. In an Electron Ionization particle source, electrons are delivered through thermionic emanation by warming a wire fiber that has electric flow going through it. The dynamic energy of the assaulting electrons ought to have higher energy than the ionization energy of the example atom. The electrons are sped up to 70 eV in the district between the fiber and the entry to the particle source block. The example being scrutinized which contains the nonpartisan particles is acquainted with the particle source in an opposite direction to the electron bar. Close entry of profoundly fiery electrons in low tension (ca. 10−5 to 10−6 torr) causes huge changes in the electric field around the nonpartisan atoms and prompts ionization and discontinuity. Expanding the electron ionization process is finished by expanding the ionization effectiveness. To accomplish higher ionization productivity there ought to be an improved fiber current, discharge current, and ionizing current. The current provided to the fiber to warm it to brilliant is known as the fiber current. The outflow current is the current estimated between the fiber and the electron passage cut. Direct inclusion electron ionization mass spectrometry (direct addition EI-MS) has been utilized for the ID of archeological glues, for example, tars, saps, and waxes found during unearthings on archeological locales. These examples are commonly explored utilizing gas chromatography-MS with extraction, purging, and derivatization of the examples. Because of the way that these examples were stored in ancient periods, they are regularly saved in modest quantities. The electron ionization season of flight mass spectroscopy (EI-TOF MS) is appropriate for logical and essential substance material science studies. EI-TOF MS is utilized to track down ionization possibilities of particles and revolutionaries, just as bond separation energies for particles and unbiased atoms. One more utilization of this strategy is to learn about regrettable particle science and physical science. The compositional varieties at the atomic not set in stone from the natural creation task. Super high settling power, little example size, high reproducibility, and mass precision (<0.4ppm) are the unique highlights of this technique. The significant item was sweet-smelling hydrocarbons in each of the three examples. Likewise, many sulfurs-, nitrogen-, and oxygen-containing compounds were straightforwardly seen when the convergence of this heteroatomic species expanded with the limit. The emanation current is the current estimated between the fiber and the electron section cut. The ionizing current is the pace of the electron landing in the snare. It is an immediate proportion of the quantity of electrons in the chamber that are accessible for ionization.In Vacuum complex technique the example is first embedded into a warmed example repository in the vacuum complex. It then, at that point, escapes into the ionization chamber through a pinhole. This strategy is helpful with profoundly unpredictable examples that may not be viable with other example presentation techniques.Gas chromatography (GC) is the most broadly involved strategy in EI-MS for test inclusion. GC can be joined for the partition of combinations of thermally steady and unstable gases which are in ideal coordinate with the electron ionization conditions.The direct-EI point of interaction is a scaled down interface for nano-and miniature HPLC in which the communicating system happens in an appropriately changed particle source. Higher responsiveness, linearity, and reproducibility can be gotten in light of the fact that the elution from the section is totally moved into the particle source. Utilizing these two connection points electron ionization can be effectively fused for the investigation of little and medium-sized atoms with different polarities.n
