Zero Discharge Plant

產品特色
When either company policies or local regulations make it mandatory for the industry to avoid any final discharge, a series of treatments need to be considered in order to recycle the water and dispose of the residual matter.
Panta Rei provides a proper biological treatment in order to carry out the degradation and reduction of the main pollutants such as BOD, COD and suspended solids. Then, a filtration and preliminary treatment stage is set. After this, a membrane treatment follows the process line. The first section is made of an ultrafiltration treatment to guarantee a fine removal of the suspended solids and protect the following membrane treatment steps. Then, the nanofiltration section performs the color removal, while rejecting also some bivalent elements such as calcium and ions such as sulfates, thus reducing the hardness and sulfate concentration of the effluent. Finally, a reverse osmosis section reduces the total dissolved solids concentration and all the residual pollutants in order to produce a high quality water whose characteristics make it suitable to be reused in the dyeing process, the boilers or any other application requiring high purity water.
It is possible to configure the reverse osmosis stage in order to obtain a larger recovery percentage, which ranges from 60% to 92% according if one, two or three steps are installed. Panta Rei provides a process analysis to determine the cost and benefits as a function of the recycled water amount, capital cost and power consumption.
