Improving the ecological safety of potato chips production by devising a method for wastewater treatment and recycling

The study deals with determining the effectiveness of mechanical and physical chemical methods for treatment wastewater potato chips enterprises. It was established that is formed at different stages production differ in composition. Wastewater after washing peeling potatoes contaminated mainly suspended soil substances about 500 mg/l, which are not settled, also has soluble organic a value COD 1,000 mg/l. found use coagulation-flocculation makes it possible to get clear water suitable reuse potatoes. Coagulant – aluminum sulfate amount 250 mg/l turned out be effective destroy stability dispersed system. To intensify sedimentation coagulated flakes particles, non-ionogenic flocculant, recommended dosed introduction coagulant 2.5 ml/l, selected. Analysis clarified indicates decrease concentration particles up 26 BOD5 values 262 176 respectively. completed studies made propose circuit potatoes, consists pre-filtering, reagent treatment, clarification, sediment dehydration. This intensively clean standards its discharge into sewage network. However, additional disinfection oxidizers, example, ozone, proposed wash vegetables an enterprise itself. intensive will allow increasing environmental safety by preventing contamination through reducing volume tap consumption
