Avaliação do reuso de água de limpeza em uma indústria de sabão em pó sintético


The present project aimed to study and evaluate the reuse of water in the cleaning process of making detergent powder, ensuring the product quality as well as reducing the environmental impact by not generating industrial effluent; observing the relationship with following parameters: color, turbidity, pH, alkalinity, COD, total phosphorus and anionic active matter (% w / w). 10 samples were collected in the effluent water reservoir tank washing production of detergent powder, as well as collections were performed 10 base powder produced with the washing water tanks production, aiming to compare the amount of active tense anion present in both samples. The results showed that there was an approximately 1% increase in the amount of anionic active matter in the base powder produced, showing an improvement in product quality without increasing the cost of raw materials. The reuse of washing water tanks production has enabled the production of a product of better quality, economy of raw material, making possible the generation of non‐industrial waste, thereby reducing the environmental impact of such effluent.
