Sources may include leaching of the plastic piping used in plumbing or from adhesives used in the original construction of the system. Water Treatment Options. There are two main methods
Technologies VOC treatment. Treatment technologies can be divided in two groups: the destructive and non-destructive. Destructive treatments are those in which the VOCs are transformed into other substances through an adequate procedure, while non-destructive treatment consists of the physical or chemical separation of VOCs from the air to be treated.

- Inorganic coagulants such as aluminum sulfate (alum) and ferric chloride are widely used due to their high efficiency in water treatment processes. They have strong coagulation properties and are effective in removing suspended solids, organic matter, and other impurities from water and wastewater.
- When were coagulants used in water treatment?
- The modern use of coagulants for water treatment started more than 100 years ago, when ferric chloride and aluminum sulfate were used as coagulants in full-scale water treatment works.
- What is the global coagulant market?
- The global coagulant market is a thriving industry driven by the increasing demand for effective water and wastewater treatment solutions, coupled with the rising prevalence of waterborne diseases and growing awareness about the importance of clean water resources.
- Does coagulation improve water treatment efficiency?
- The performance of coagulation is the major factor in improving water treatment efficiency. Water industries globally consider coagulation/flocculation is one of the major treatment units used to improve overall treatment efficiency and cost effectiveness for water and wastewater treatment.
