Flow diagram 2: Wastewater treatment for integrated washing facility closed loop – recycling Source: A to Z Industrial Services, Indore, India The treatment done at various stages are as follows: Oil water separator Oil and grease separators are installed to remove oil and grease – based on density differences. Mud separators are designed to remove the inorganic Mud separator or grit chamber – particles, such as sand, gravel, grit etc. of size 2 mm or larger from wastewater. Equalization tank The equalization tanks are provided to balance fluctuating flows or – concentrations of wastewater and/or to assist self-neutralization. Chemical dosage tank In a chemical dosage tank, certain chemicals like alum and lime – are added to aid settling of very fine suspended particles present in wastewaters by changing them into flocculated particles. The amount of chemical used in the dosing tank depends upon the quantity of wastewater to be treated. Settling tank Settling tanks are designed to remove the flocculated particles from – wastewater via the settling phenomenon under force of gravity. In this type of filter, activated carbon is used to remove Activated carbon filter – odours, dissolved gases, heavy metals etc. from the wastewater. Resin softener The main function of resin chambers is to remove dissolved salts by the – ion-exchange mechanism. Sludge dewatering system In this system, the settled sludge from the settling tank is – dewatered and dried mostly by the application of solar heat.
