Reducing wastewater pollution from degreasing baths while saving costs in terms of environmental protection is an important issue in electroplating plants.
The manufactured components must be degreased and freed from corrosion protection before a painting or coating process. With the light liquid separator from LK Metall, it is possible to use the contaminated wash liquor in the degreasing bath for a significantly longer period of time without additional chemicals by extreme removal of the accumulating oil.
LK light liquid separator: suitably designed for degreasing processes
Continuously remove oil from wash liquor
To degrease the components, they are immersed in degreasing baths and cleaned with the help of cleaning chemicals at a temperature of up to 90 °C. The oils and greases (light liquids) remain in the bath and, after a certain concentration, lead to saturation of the wash liquor. In turn, the floating oils contaminate the components and lead to a loss of quality in further processing. Suction of the oil by a simple skimmer on the surface of the wash liquor is often insufficient and too low in efficiency. Integrated into existing galvanizing processes, the easy-to-operate and low-maintenance light liquid separator from LK Metall continuously removes the oil from the wash liquor. A physically operating oil separator built into the system solves this task reliably and particularly economically. The disposal intervals are considerably extended. The oil separator guarantees high safety and long service life.
Process water treatment: degreasing with LK separator system
Longer service life reduces disposal cycles
Fully integrated into the ongoing production process, the service life of the degreasing bath is extended from about one week to around eight weeks. Compared to weekly disposal, this means an increase in service life of up to 8 times and thus a significant reduction in disposal cycles. An additional cost savings is achieved in the reduced load on the neutralization plant. Thus, on average, more than 100 liters of pure oil are separated within the first eight weeks after startup. At the same time, this means a substantial saving in chemicals. Adapted to the corresponding size of the degreasing bath, the LK light liquid separator can be integrated into almost any production process.
