What is a water softener?
Water Softeners. A water softener is a device that reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.”. Distillation Systems.
What is the first step in wastewater treatment?
The first stage of a water treatment process is to remove large pieces of waste and debris from the wastewater. Human and animal waste, sticks and stones, and trash are removed using screens and rakes. Screens come in different sizes so that larger material is caught first. The wastewater continues on the way passing through smaller and smaller screen sizes. Eventually, it will pass through a fine screen before it moves to the next process. All of that debris and waste that is caught goes to incinerators, compost, or landfills.
Why is wastewater important?
Why clean it? There are several reasons, but the most important is that wastewater is full of bacteria that can harm you.
