Water treatment is any process that improves water quality to make it suitable for a specific end-use. The end-use can include, irrigation, water recreation, drinking water, or many other uses. Therefore water treatment is vital to our modern society, especially in a water-scarce country like South Africa. 

With it being such an important process, it is no surprise that there are 155 water treatment companies in South Africa. These companies all deal in different aspects of water treatment. With so many water treatment companies in South Africa, we decided to put together a list of the 5 best

Types of Water Treatment Plants

Before we get to the best water treatment companies in South Africa. We want to give you a better understanding of the types of water treatment plants that exist. Broadly speaking there are three types, which we will look at below.

Wastewater Treatment Plant (WWTP)

Wastewater refers to water that has been used in agricultural, domestic, and industrial activities. It can be divided into two categories. Sewage water comes from domestic activities like toilets, showers, and sinks, and industrial wastewater comes from manufacturing, industrial, and commercial activities. Wastewater treatment plants use a variety of physical and chemical filtration methods, to recover clean usable water from wastewater.

Demineralization (DM) Treatment Plants

Demineralization involves the complete removal of dissolved minerals or solids from the water. Demineralization treatment plants work on the principle of ion exchange, which uses deionization to remove ionic contaminants in the water. This is usually used for industries that need very pure water, like the food and beverage industry.

Reverse Osmosis (RO) Treatment Plants

Reverse osmosis removes impurities from water, by using a semi-permeable membrane. The contaminated water is forced through the membrane under high pressure. The membrane allows the water molecules to pass through while other salts and contaminants are left behind. This removes 95%-99% of the dissolved salts. Reverse osmosis is used in desalination plants, which turn salt water into usable fresh water.
