Everything You Need To Know About Purification & Filtration Plants

Purification & Filtration Plants

Water is considered a scarce resource. Despite its apparent abundance, very little water is available for human consumption. Fortunately, modern technology is helping to improve the collection and purification of water, effectively increasing availability and potentially saving lives. Naturally, the best washing and clarification procedures are used to ensure all undesirable elements are removed from the water.

Here’s what you need to know.

Purification & Filtration Plants Explained

Water purification is the process of removing minerals and chemicals from water. In some cases, the elements being removed are toxic. In others, there are simply high quantities of undesirable minerals and contaminants.

Purification methods are designed to clean water, providing safe water for people to drink. The most common option is distillation. Water is heated until boiling point. It becomes a vapor which travels upward. It then hits a cooler surface and the steam becomes water again. In the process, all contaminants are eliminated.

In contrast, filtration simply means passing the liquid through filters which are designed to allow water through and capture anything else. In both cases, the slurry is usually screened to eliminate large debris before the filtration process is completed.

In industry, the most common example of a filter is the filter press. This large machine is often used with slurry produced when mining or creating concrete. It consists of a large holding container which automatically maintains the slurry at the right consistency.

This is then fed through two plates pressed together. These sometimes include inflatable elements to ensure every drop of water is squeezed out of the slurry.

The solid residue remains in the tanks and can be removed. The extracted water then goes through a series of filters, removing any remaining contaminants and creating pure water.

In short, purification seeks to eliminate contaminants in water via the use of distillation, filtration removes the contaminants through the use of mechanical or even chemical processes. For example, reverse osmosis is an effective way to remove minerals from water. It utilizes nature and the natural desire for heavy molecules to collect in the same place.

Applications For Filtration & Purification

Filtration and purification are commonly used to extract contaminants from water, leaving you with clean and pure water. However, that’s not the only application for this technology.

Machines have been designed to filter materials, including substances like coal or even gravel. The machines are capable of separating the materials, effectively creating a collection of recyclable materials.

The level of filtration required determines the type of machine you need to order. It’s possible to filter out very fine sand in slurry and recover it.

The applications are numerous. However, it’s worth noting that dry screening was the

norm. Today, this has been replaced with washing and filtering these substances. It’s more effective at cleaning the product and creates less waste

Summing Up

If you’re dealing with water, regardless of what material it is trapped in, a good filtration or purification system is essential. The only question is which method is best suited to your needs.

Alberta to launch new primary care agency by next month in health overhaul

Published

 on

 

CALGARY – Alberta’s health minister says a new agency responsible for primary health care should be up and running by next month.

Adriana LaGrange says Primary Care Alberta will work to improve Albertans’ access to primary care providers like family doctors or nurse practitioners, create new models of primary care and increase access to after-hours care through virtual means.

Her announcement comes as the provincial government continues to divide Alberta Health Services into four new agencies.

LaGrange says Alberta Health Services hasn’t been able to focus on primary health care, and has been missing system oversight.

The Alberta government’s dismantling of the health agency is expected to include two more organizations responsible for hospital care and continuing care.

Another new agency, Recovery Alberta, recently took over the mental health and addictions portfolio of Alberta Health Services.

Experts urge streamlined, more compassionate miscarriage care in Canada

Published

 on

 

Rana Van Tuyl was about 12 weeks pregnant when she got devastating news at her ultrasound appointment in December 2020.

Her fetus’s heartbeat had stopped.

“We were both shattered,” says Van Tuyl, who lives in Nanaimo, B.C., with her partner. Her doctor said she could surgically or medically pass the pregnancy and she chose the medical option, a combination of two drugs taken at home.

“That was the last I heard from our maternity physician, with no further followup,” she says.

But complications followed. She bled for a month and required a surgical procedure to remove pregnancy tissue her body had retained.

Looking back, Van Tuyl says she wishes she had followup care and mental health support as the couple grieved.

Her story is not an anomaly. Miscarriages affect one in five pregnancies in Canada, yet there is often a disconnect between the medical view of early pregnancy loss as something that is easily managed and the reality of the patients’ own traumatizing experiences, according to a paper published Tuesday in the Canadian Medical Association Journal.

An accompanying editorial says it’s time to invest in early pregnancy assessment clinics that can provide proper care during and after a miscarriage, which can have devastating effects.

The editorial and a review of medical literature on early pregnancy loss say patients seeking help in emergency departments often receive “suboptimal” care. Non-critical miscarriage cases drop to the bottom of the triage list, resulting in longer wait times that make patients feel like they are “wasting” health-care providers’ time. Many of those patients are discharged without a followup plan, the editorial says.

But not all miscarriages need to be treated in the emergency room, says Dr. Modupe Tunde-Byass, one of the authors of the literature review and an obstetrician/gynecologist at Toronto’s North York General Hospital.

She says patients should be referred to early pregnancy assessment clinics, which provide compassionate care that accounts for the psychological impact of pregnancy loss – including grief, guilt, anxiety and post-traumatic stress.

But while North York General Hospital and a patchwork of other health-care providers in the country have clinics dedicated to miscarriage care, Tunde-Byass says that’s not widely adopted – and it should be.

She’s been thinking about this gap in the Canadian health-care system for a long time, ever since her medical training almost four decades ago in the United Kingdom, where she says early pregnancy assessment centres are common.

“One of the things that we did at North York was to have a clinic to provide care for our patients, and also to try to bridge that gap,” says Tunde-Byass.

Provincial agency Health Quality Ontario acknowledged in 2019 the need for these services in a list of ways to better manage early pregnancy complications and loss.

“Five years on, little if any progress has been made toward achieving this goal,” Dr. Catherine Varner, an emergency physician, wrote in the CMAJ editorial. “Early pregnancy assessment services remain a pipe dream for many, especially in rural Canada.”

The quality standard released in Ontario did, however, prompt a registered nurse to apply for funding to open an early pregnancy assessment clinic at St. Joseph’s Healthcare Hamilton in 2021.

Jessica Desjardins says that after taking patient referrals from the hospital’s emergency room, the team quickly realized that they would need a bigger space and more people to provide care. The clinic now operates five days a week.

“We’ve been often hearing from our patients that early pregnancy loss and experiencing early pregnancy complications is a really confusing, overwhelming, isolating time for them, and (it) often felt really difficult to know where to go for care and where to get comprehensive, well-rounded care,” she says.

At the Hamilton clinic, Desjardins says patients are brought into a quiet area to talk and make decisions with providers – “not only (from) a physical perspective, but also keeping in mind the psychosocial piece that comes along with loss and the grief that’s a piece of that.”

Ashley Hilliard says attending an early pregnancy assessment clinic at The Ottawa Hospital was the “best case scenario” after the worst case scenario.

In 2020, she was about eight weeks pregnant when her fetus died and she hemorrhaged after taking medication to pass the pregnancy at home.

Shortly after Hilliard was rushed to the emergency room, she was assigned an OB-GYN at an early pregnancy assessment clinic who directed and monitored her care, calling her with blood test results and sending her for ultrasounds when bleeding and cramping persisted.

“That was super helpful to have somebody to go through just that, somebody who does this all the time,” says Hilliard.

“It was really validating.”

Listeria outbreak linked to plant-based milk seems to be over: PHAC

Published

 on

 

The Public Health Agency of Canada says a Listeria outbreak linked to several plant-based milks appears to be over with no additional cases reported since August.

The federal agency says its investigation is now complete and Listeria was found within the production environment of Silk and Great Value plant-based refrigerated beverages.

However, PHAC says it was not able to identify the “primary site” of the contamination within that environment and that production will remain paused until the Canadian Food Inspection Agency is satisfied with renovations to the facility.

The CFIA previously stated that the source of the illness was traced to a specific production line at Joriki, a third-party facility in Pickering, Ont., used by plant milk manufacturer Danone Canada.

The last tally of cases reported on Aug. 12 remains unchanged, with 20 confirmed infections in Ontario, Quebec, Nova Scotia and Alberta, and three deaths.

The illnesses prompted a national recall of several Silk and Great Value plant-based milk products on July 8 with Oct. 4 as the latest best before date.
