Sewage treatment has assumed a new magnitude itself now, against the backdrop of the peril of fresh water becoming depleted. Wastewater comprises water used differently, sewage and storm-water, around the community. Most communities produce sewage from household as well as nonhousehold causes. Unless properly treated, sewage can injure the society and pollute the environment. Here I have expounded on solids removal from wastewater. How may we withdraw solids sinking to the bottom from the sewage water? Easily said and done. By means of a settling tank. It is constituted of the following units: (a) Sedimentation tanks: either chemical or plain precipitation (b) Septic (Imhoff) ... Read Full Story

It's not a widely published fact, but that's no reason why it should not be a widely acknowledged problem. The world's supply of fresh water is slowly running dry. Forty percent of the world's population is already reeling under the problem of scarcity. Most of the diseases plaguing the world are water-borne. And while there is a child born every eight seconds in America, there is a life taken every eight seconds by some water-borne disease in other parts of the world. Is it the lopsided distribution of fresh water that is causing climate change, or is it the climatic change that is causing ... Read Full Story

Recycling and reuse of wastewater will do away with the need of using fresh water. The extent to which the processes involved in wastewater treatment are cost effective and easy to follow will act as an impetus. Hence discussing about the processes involved in wastewater treatment and their relative merits and demerits becomes pertinent. Like Sedimentation tanks, Septic tanks (Imhoff tanks) can play a major role in the process of removing solids from wastewater. Designed by Karl Imhoff of Germany, an Imhoff tank is an improved septic tank in which the incoming sewage or influent is not allowed to get mixed up with the ... Read Full Story

There are some important things you must take into account before you begin wastewater treatment. Acidity: Can water be acidic in taste? Most natural water, domestic wastewater and many industrial wastewater are buffered by a carbon dioxide-bicarbonate system. Acid waters are of concern because of their corrosive characteristics and the expense involved in removing or controlling the corrosion-producing substances. Mineral acids are measured by titration to a pH of about 3.7. Alkalinity: When will the water be alkaline in taste? The alkalinity of natural water is primarily due to the salts of weak acids. Although, weak or strong bases may also contribute. Natural water ... Read Full Story

Quality treating and reusing wastewater will remove the necessity of employing fresh water. The degree to which the stages of wastewater treatment are cost effective and provide easy following will give a kick start to employing water treatment. Therefore debating the procedures involved in wastewater treatment and their comparable advantages and disadvantages, becomes relevant. Like tanks using sedimentation, Septic tanks (Imhoff tanks) can be largely instrumental in the continuous operation of eliminating solids from sewage. Conceived by Karl Imhoff from Germany, an Imhoff tank is a bettered septic tank in which the inflow of wastewater may not be permitted to get blended with the ... Read Full Story
