Designing of tanks for dye waste treatment plant.Dye waste treatment plant consists of two tanks, equalising and Neutralizing tanks.
Dye waste from different industries consists of different chemicals which will affect the concrete directly.
It is possible to construct treatment plant without any equalising tank?
Waste that from industry can directly fed to Neutralizing tank and then to other treatment process?
The equalizing tank is used to get a homogeneous solution and minimize the variations in water properties before dosing the right chemicals in the neutralizing tank. To remove it and use only neutralizing tank, you shall need a fast response control system that can measure the properties of the water before the inlet and re adjust the chemical dosing. Difficult but not impossible. Then you shall need a polishing step, usually with adsorption on some sort of cheap activated carbon
Good luck
Different industries contribute different chemicals when this chemicals added to form high molecular weight substances such as in the formation strong solutions of hydrochloric acid and sulphuric acid.
In such cases these acids will directly affect the concrete or any other materials which is employed for designing of tank.
What are the expected chemicals?
Sir, If we consider a City n number of dyeing plants are established and we are not able to check each and every plant about what type of chemical are being used for Coloring purpose.
Dye industry consists of different chemicals which are used for Coloring of different materials.In such cases we are not able to identify what type of chemical is discharged from the industry.
Bala Murali: It is a big problem to treat wastewater without knowledge what should be removed. I had an experience from Gujarat with a wastewater treatment plant for treatment of wastewater from a cluster of various plants (textile, dying, production of chemicals and pharmaceuticals ....). The solution for this case was to make inventory of all wastewaters comming to the wastewater treatment plant and in some cases install a pretreatment system at the place before wastewater mixing. This solution improved efficiency of wastewater treatment and decreased operational costs by 17 %. The pretreatment systems reduced the most problematic pollutants for much lower costs in comparison to elimimnation of these pollutants from huge amount of mixed wastewater.
