In the field of water treatment we focus with our Lohtragon® range on specific water purification applications. The target is to make water suitable for drinking, medical use and industrial use with particular requirements. For the reduction of impurities and contaminants Lohtragon® Ferric Sulfates are used in specific water purifier formulations.
Have a look at the following case study.
Case study:
Our partner Bishan Gari offers such water purifier sachets to prepare potable water in areas where the drinking water is not directly accessible.
Another Lohtragon® application example in this field is the sustainable recovery of valued process water in automated paint booths. Water curtains are used as fitration systems to capture paint overspray and modern spray paint systems build up emulsions with the process water used in these water curtains. Metal salts based on Calcium, Iron and Aluminium are effective demulsifiers in the waste water treatment step.
Fire-extinguishing chemicals have to be harmless to health and the environment, as they are purposely released into the environment. Therefore starting products used must be pure and not pollute the environment with additional heavy metals and other chemicals. Extinguishing agents are selected to suit the type of fire to be extinguished and are divided into classes accordingly. Lohtragon® offers alkaline carboxylates for fire-extinguishing agents specifically for cooking fat fires. The metal salts work by saponifying the oil or fat. This layer acts as a block and prevents the access of further oxygen.
Have a look into our Info Sheet for Fire Safety for more Information on products, features and benefits of our Lohtragon® range for fire-extinguishing agents.
