| titleOfInvention | Method for regeneration waste solution from the aluminium-ammonia alum production |
| abstract | The method is applied in the chemical-pharmaceutical industry for production of aluminium oxide and aluminium hydroxide. It allows for efficiently utilise the waste solution from the production of aluminium-ammonium alum with a reduced quantity of the waste products. According to the method, the waste solution from the production of aluminium-ammonium alum is concentrated until the content of aluminium sulphate reaches 20 to 30 per cent in weight and then - at a temperature of 15 to 35 degrees C - crystalline ammonium sulphate is added to the solution until a concentration of 35 to 42 per cent in weight is reached. The produced crystals of unpurified ferric-ammonium alum are removed through filtration and the filtrate is reused in the technological cycle. |
