Companies embrace water reuse systems because of their environmental and economic benefits

Growing environmental concerns have led to recurring discussions about the need for greater responsibility and awareness in the use of available water resources. With this in mind, industrial plants are adopting systems of water reuse in order to increase the number of water use cycles.

 

The system

One of the models conceived and supplied by Ecosan – the market leader in equipment for the primary and secondary treatment of domestic and industrial effluent – for the sugar cane and alcohol sector, was designed with a maximum flow of 15 m3/h and comprises the following: Mechanized Grit Separator – SAM, Oil-Water Separator – TPI, Flock Chamber with Axial Turbine Blade Flocculator, High Flow Rate Modular Decantation Chamber,  two Filtration Chambers with Sand Bed and Activated Carbon Filtration, as well as a Chemical Dosing System.

As Ecosan’s Managing Director André Telles points out, the Wastewater Treatment Plant will produce clarified and filtered water originating from car washes and cleaning of parts which may be reused in industry, for cleaning floors, in gardening, and in similar contexts, but not for human or animal consumption.

 

Understanding the process

The first stage consists of removing the sand from the water by gravitational means. From there the water passes through an oil-water separator to clarify the water and ensure correct disposal of the oil.

The Plant’s flow rate is controlled by parshal flume. The liquid is channeled to the flocculation chambers where the water’s impurities coagulate and agglutinate. This is followed by the water decantation process.

Finally, the liquid undergoes an antifoam filtering and dosing process, the objective being to separate off the detergent present in the treated water.
