Commercial Water Purification Systems
An Overview of Commercial Water Purification Systems Apart from being one of the vital requirements for all forms of life on our planet, the simple molecule formed by combining two atoms of hydrogen with one atom of oxygen plays a crucial role in many aspects of daily life. Both at home and in most businesses, […]
Agricultural Water Treatment Systems
The Nature and Purpose of Agricultural Water Treatment Systems Contrary to popular opinion, it is farming and not the mining industry that is the biggest consumer of the world’s water, accounting for a massive 62 per cent of South Africa’s total usage. By comparison, all other industries combined consume around 11 per cent, while domestic […]
Mining Water Treatment
The Usage and Treatment of Water in the Mining Industry Few industries have more potential to damage the environment than mineral exploitation. Many of the processes essential to this industry employ and subsequently contaminate vast quantities of water. Unless suitably treated, the effluent from mines can have severe consequences if allowed to seep into streams, […]
Wastewater Management
Wastewater Management is a Shared Responsibility Whether as ordinary citizens, business owners or industrialists of South Africa, we owe a debt of gratitude to the men and women responsible for operating the nation’s many municipal water treatment plants. Without their efforts, we would drink from the same infected rivers and lakes we use to wash […]
Desalination / Water Treatment
Desalination and Other Forms of Water Treatment Despite covering about 71 per cent of the planet’s surface, seawater is not suitable for consumption by land-based animals, and only specialised marine plants can survive in it. Unfortunately, most freshwater is locked in glaciers and icebergs, so little is readily accessible for human use. In practice, of […]
Agricultural Wastewater Treatment
Effective Agricultural Wastewater Treatment is Vital for Conservation Few people would doubt that industry consumes most of the world’s water. However, it is not mining, petrochemicals, logging, power generation or similar bulk users that are the thirsty ones within this sector. In practice, their combined usage of around 12% is less than half that consumed […]
Industrial Water Treatment
The Purpose and Practice of Industrial Water Treatment Given the more immediate threat of the Covid-19 pandemic, it is easy to forget that South Africa and most of the world’s nations face a far greater crisis. The three years of limited rainfall that, in early 2018, led to Cape Town’s “Day Zero” drought is an […]
Industrial RO Systems
The Operation and Role of Industrial RO Systems However closely one may inspect the colourful plants we grow, it is hard to believe that any feature of their physiology could lead to developing an advanced nanofiltration technology with numerous applications in many different industries. Nevertheless, the principle underlying the industrial RO systems that have revolutionised […]
Desalination Plant
The Growing Dependence on Desalination Plants While extracting the salt from seawater to render it drinkable is currently being seen as a gamechanger in the global battle for water conservation, the concept is thousands of years old. In practice, the sailors of ancient Greece boiled seawater to obtain freshwater by evaporation, while their Roman peers […]
Water Filtration Systems
Water Filtration Systems and their Uses While the originators may not have fully understood its action, the concept underlying modern water filtration systems has its roots in Ancient Greece. The physicians of that time considered boiled and filtered water to be not merely cleaner but also healthier. However, lacking any knowledge of microorganisms and their […]
