Waste Water Treatment
Dr. Majid Mohiuddin (Hashmi)
Industries use water that obtained from the water treatment system for a variety of purposes, such as: - For manufacturing goods. - For heating. - For cooling. - As carrier of raw material. - As carrier of waste matter. - As a solvent. ● The resulting water is then classified as a wastewater. If a waste stream is found to be hazardous due to corrosivity, neutralization is the primary treatment used. It is used as a pretreatment system before a variety of biological, chemical, and physical treatment processes. It is the process of adjusting the pH of water through the addition of an acid or a base, depending on the target pH and process requirements. Some processes such as boiler operations and drinking water standards need neutral water at a pH of 7.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
