How can Using the wrong chemicals in WWT can be dangerous?
We value wastewater treatment from both a personal and an environmental aspect. Wastewater treatment plants employ sophisticated procedures that involve the use of various chemicals to treat used water in order to remove pollutants, toxins, and other organic components from the wastewater and safely return it to the environment.
Water or wastewater treatment plants employ a variety of procedures, including biological and chemical processing, which necessitate the use of various chemicals to clean the wastewater and balance the pH level.
Many sanitary wastewater treatment programs, industrial uses, and drinking water production, employ various coagulants or chemicals. They can be pretty effective — when used correctly. The chemical might be harmful if used in the incorrect spot.
What roles do alum and ferric chloride play in water treatment?
Coagulants, as every water treatment professional is aware, are employed in the initial phase of water treatment to destabilize the water so that micro flocs can be formed. This is followed by a polymer, which expands the floc by providing a greater charge.
Alum and ferric chloride are two well-known "commodity chemical" coagulants!
What is the significance of the usage of alum and ferric chloride?
Some water treatment professionals are just unaware of alternative options. Companies that offer alum and ferric chloride aren't advertising competitive products, and those who do market alternative products are having difficulty getting the word out.
Disadvantages of using excess Alum
Alum requires hydroxide and alkalinity and only functions within a specific pH range; large volumes are frequently required. The more alum you need to feed, the dirtier the water.
It effectively stops operating when a certain amount of alum is fed. Increasing the alum concentration will not help treat really unclean water. In really unclean water, alum just does not function.
It generates a lot of sludge. Furthermore, the sludge it produces is difficult to dewater because it becomes gelatinous. Assume, a tiny plant consumes a million gallons of water per day and receives 25 parts alum on a wet basis. That implies they're putting in 208.5 pounds of alum, but 101 of those pounds are simply waste materials that the plant must deal with on a daily basis. That's 3,000 pounds over the course of a month. Over the course of a year, that's nearly a full truckload of extra weight owing to the alum alone.
Disadvantages of using excess Ferric chloride
It is extremely corrosive. Because it will chew through items like the flow meter—and virtually everything other than stainless steel.
The pricing is subject to change. The price of the components required to create ferric chloride, whether iron or hydrochloric acid, fluctuates a lot, which can have a big impact on the price of ferric chloride itself. Customers that use ferric chloride are currently experiencing price hikes of up to 40%. Many water treatment plants can't afford a 40% price rise; therefore, they're seeking for alternatives.
Wastewater treatment facilities and other industrial water treatment plants must utilize a variety of different methods and chemicals to process wastewater and make it reusable. However, understanding the physics and rationale behind these approaches is required since they need the careful manipulation of various chemicals to treat the effluents in the wastewater. If chemicals used in wastewater treatment is not correct, then it can be proved to be a danger for the consumption.
Industrial wastewater plants are indeed responsible for adhering to numerous Government regulations while treating wastewater; therefore, it is beneficial to have a professional wastewater expert as they have a better understanding of the subject matter and can assist you in navigating different chemical procedures.
