Why Wastewater Treatment is So Important

Did you know that every day, humans produce an enormous amount of wastewater?

For more information, please visit our website.

 

&#;Globally, about 359 billion cubic metres of wastewater is produced each year, equivalent to 144 million Olympic-sized swimming pools,&#; says Edward Jones , PhD researcher at Utrecht University and lead author of the study.

 

Worldwide, it is common practice to pump enormous volumes of wastewater into rivers, oceans and streams. This has extremely negative effects on the environment, fisheries, animals, and that&#;s not to mention it&#;s an aptly named &#;waste&#; of water too. To put it simply, wastewater is any form of water that has been contaminated by a commercial or domestic process. This includes water that was used for sewerage and water that&#;s a by-product of large-scale industries such as mining and manufacturing.

 

Wastewater treatment is crucial for protecting our environment and ensuring that we make the most efficient use of our resources. In this blog post, we will discuss the effects of wastewater on the environment and why proper treatment is so crucial.

 

What is wastewater and what does the treatment of it entail?

Wastewater treatment is a process that converts wastewater from its unusable state into an effluent that can be either returned to the water cycle with minimal environmental issues or reused for another purpose. It&#;s a treatment that, given its importance, more and more governments are finally realizing that they need to take actionable steps to improve their wastewater treatment processes. Uruguay, which happens to be one of the most developed countries in South America, recently implemented modern water-treatment systems following a two-year construction project and a $21 million investment. The aim was to treat wastewater generated by civilians and minimise pollution. As a result, Uruguay&#;s water system no longer transmits disease and the nation has since stayed free from cholera epidemics.

 

Why is wastewater treatment so important?

Wastewater treatment is crucial in order to protect our environment and the health of both humans and animals. When wastewater is not treated properly, it can pollute our water sources, damage natural habitats, and cause serious illnesses.

 

Effectively, wastewater treatment plants do as described; they treat the water that goes down our drains before discharging it back into the environment. Regardless of the efforts that are being made to install these plants worldwide, more is required. Water is one of our most important resources and it&#;s being squandered. There are multiple ways to treat wastewater, and the better the process, the higher the percentage that can be reused before it gets dumped into the ocean.

The public has begun to stand up to oil companies about fracking and wastewater and the rules are slowly changing, especially in terms of transparency and its effects on the environment. It&#;s a good thing that the industry is under scrutiny as the more transparency that&#;s required by law, the better. We need to raise the levels of expectation for oil companies, mines, and other large-scale industries as they&#;ve been unregulated and sold to the highest bidder for too long.

 

The Future of Wastewater Treatment

It wouldn&#;t take much to make a huge change in this area, and it does need to happen, desperately. Great technological leaps are being made in the likes of Scandinavia in regards to recycling trash to create energy. In fact, Sweden actually ran out of its own waste and it now imports over 700,000 tonnes of waste from other countries. Less than 1% of their waste ends up at the dump and their wastewater is purified to the extent of being potable. This is an example of innovation in an environmental capacity and Sweden doesn&#;t have to be light years ahead of everyone else.

 

The re-use of treated wastewater has become a viable option to minimising water scarcity problems. The world has a growing and developing population and as things stand right now, we&#;re on a downward slope in terms of water conservation. Having said this, with some smart thinking, wastewater treatment and some generous open mindedness (something previously almost unheard of from corporations) we can turn this around and make much needed changes all around the globe.

Wastewater Treatment Plants

Most homes and businesses send their wastewater to a treatment plant where many pollutants are removed from the water. Wastewater treatment facilities in the United States process approximately 34 billion gallons of wastewater every day. Wastewater contains nitrogen and phosphorus from human waste, food and certain soaps and detergents. Once the water is cleaned to standards set and monitored by state and federal officials, it is typically released into a local water body, where it can become a source of nitrogen and phosphorus pollution.

Some wastewater treatment plants are able to remove more nitrogen and phosphorus from their discharges than others depending on their equipment and how they treat wastewater. Enhanced treatment systems enable some wastewater plants to produce discharges that contain less nitrogen than plants using conventional treatment methods. Upgrading wastewater treatment systems is often expensive for municipalities and rate payers, but upgrades can pay for themselves or end up saving a plant money. Other treatment plants are able to adjust operations and repurpose existing equipment to remove additional nutrients. This approach, often referred to as optimization, is usually much less expensive than upgrades, and for many plants can result in cost savings by reducing energy demand and treatment chemicals. In some cases, optimization along with further technology upgrades may be necessary to achieve the nutrient reduction goals of the plant. Various strategies to reduce nitrogen and phosphorus loads from wastewater treatments plants are being pursued across the country.

Wastewater treatment plants process water from homes and businesses, which contains nitrogen and phosphorus from human waste, food and certain soaps and detergents.

Septic Systems

Septic systems can easily become a source of nutrient pollution if not properly maintained.

Approximately 20 percent of homes in the United States use septic systems that locally treat their wastewater. When a septic system is improperly managed, elevated nitrogen and phosphorus levels can be released into local water bodies or ground water. An estimated 10 to 20 percent of septic systems fail at some point in their operational lifetimes. Common causes of septic system failure include aging infrastructure, inappropriate design, overloading with too much wastewater in too short a period of time and poor maintenance.

Homeowners are responsible for maintaining their septic systems in most cases. To protect and maintain their system, homeowners should:
