Project Title: Quality Analysis of Landfill leachate treatment & its treatment by Distillation Dates of Project: August 2005 to May 2006 (10 Months) Name of Organization: P.G Environmental Engineering Department, PEC University of Technology, Chandigarh (Formally Punjab Engineering College, Chandigarh) Location: University My Role: Student of Master of Environmental Engineering
As we are progressing thousands of people from villages are migrating to cities. As a result of this population of cities is increasing day by day. A huge amount of solid waste is generated by the daily activities of people. Landfilling is the commonly used process which deals with the disposal of solid wastes on or in the upper layer of earth’s mantle .Within a landfill, a complex sequence of physical, chemical, and biological reactions occurs. As a consequence of these processes, refuse is degraded or transformed. Water percolates through the landfill and contaminants are leached from the solid waste. This leads to the formation of thick black colored liquid called Leachate. Leachate is having high Chemical Oxygen Demand (COD), Chloride and Sulphate content. If Leachate is not treated properly then it can cause pollution of groundwater, health problems and can adversely affect the environment.
Distillation of the landfill Leachate is the less travelled path. Most of the people reject the idea of distillation of landfill Leachate as it requires large amount of energy for distillation. I have opinion that energy requirement for the Distillation of landfill Leachate can be met with the gas which is generated by the decomposition of the solid waste at the Landfill. Solar energy option can also be used for the above said purpose. But this aspect was beyond the scope study of my Master’s thesis.
In my study I only concentrated about the technical aspects of the treatment of landfill leachate using distillation process. I collected landfill Leachate from the DadduMajra site which is located in Chandigarh. Chandigarh is a beautiful town of Northern India with a population of nearly 1.5 million. Chandigarh is among the top cities in India based on quality of life index. Solid waste of the town is sent to the DadduMajra site. Leachate collected was analyzed by me in Environment laboratory of my department. I also collected groundwater sample from a Hand pump near to the site to analyze the impact of landfilling on the Ground water Quality.
I completed my project under the guidance of Assistant Professor Shakti Kumar. Leachate was tested for various parameters like concentration of Chlorides, Sulphates, Chemical oxygen Demand (COD) and pH using methods given in “Standard Methods for Examination of water and waste water” published by “American Public health Association”. One stage distillation was done on Landfill Leachate sample to study the changes in Leachate quality parameters.
For examining two stages distillation process, the distillate from the stage one was used as feed to the second stage. With this I have compared the changes that have occurred in Quality parameters of Landfill Leachate before and after the treatment of one sage and two stage distillation of landfill leachate. The effect of landfill Leachate on the Ground water Quality was also studied.
Since I was the only project patron so I managed all the project management by myself.

Project Title: Technical proposal for making 900 MLD (Million Litre/Day) Water Treatment Plant Dates of Project: April 2007 to December 2007 (Nine Months) Name of Organization: Suez India (Pvt) Ltd Location: Gurgaon, Mumbai, India My Role: I worked as Engineer for Technical Proposal Manager & my duty included making Technical Proposal & doing calculations along with the design work.
Mumbai is the largest city in India and often called as economic capital of India. Mumbai and surrounding suburbs are home to around 20 million Indians. Population of this city is increasing as more and more people are migrating from smaller town to big cities in India for job opportunities. This has increased the demand of drinking water.
In the year 2007, Municipal Corporation of Mumbai invited bids from water treatment expert companies to construct the 900 Million Liters per day water treatment plant at Bhandup. Suez India made a successful bid and after the technical and commercial negotiations won the project. I and my team played an important role in this project. I worked with my technical manager Mr. Yogesh. D Chaware.

Project Title: 40 m3/hr. Potable water Treatment Plant for 2800 MW Gas based Rabigh Power Plant Dates of Project: June 2011 to December 2012 Name of Organization: Doosan Heavy Industries & Construction Co. Ltd(DHI), EPC Business group (Water Treatment Section) Location: Saudi Arabia My Role: Environmental Engineering
In the year 2011 DHI won 4 billion USD Project for the construction of 2800 MW gas based power plant. This was one of the biggest projects constructed by DHI. Before the start of the Power production it was important that we have an up to date new potable water treatment plant in order to fulfil the requirements of the drinking water for the staff and the colony of people working in the power plant. I calculated that 40 m3/hr Potable water treatment plants will be required for the potable water requirement of the power plant staff and the colony. I handed complete potable water project from basic design till the handover to the owner.
The 40 m3/hr Potable water Treatment plant was designed by me designed to treat distilled water, continuously adding specific chemical solutions by means of dedicated dosing systems, in order to make the water potable according to WHO recommendations.
I worked as responsible Engineer for the handling the complete potable water treatment system from concept development to the handover of the project. In detail my responsibility included calculating the Potable water demand for the complete power plant, Basic design, Detailed design, selection of vendor for supply of the tanks, Pumps and package vendor selection, handling design activities , finalization of specification of mechanical equipment, process design and submission to the owner for approvals, incorporating Owner’s comments. O&M documents preparation. I also have to interact with Electrical, I&C, architectural and Procurement teams for carrying out the associated activates of the Package items.
My roles & responsibilities were as following

Project Title: Technical proposal making & basic design for Pretreatment, Demineralization & waste water treatment Plants for 2X660 MW ‘’Jawaharpur Super thermal Power Pant’’ Dates of Project: October 2015 to October 2017 (24 months) Name of Organization: Doosan heavy Industries & Construction Co. Ltd, EPC Business Group. (Water Treatment Section) Location: Seoul, South Korea My Role: Environmental Engineer
In the year 2015 Uttar Pradesh Rajya Vidyut Utpadan Nugam Limited floated the tender for the construction of 2x660 MW “Jawaharpur Super thermal Power Plant”, Uttar Pradesh, India. Doosan decided to make the Bid for this project. I was tasked to prepare the technical proposal and basic design was assigned to water treatment section. I was selected by my Team Head as responsible engineer to prepare the technical proposal and to carry out the basic design (in case Doosan wins the Project). In the year 2016 Doosan won the multimillion dollar project. I carried out work related to Technical proposal making and thereafter and basic design for 4500 m3/hr Pretreatment Plant (PT) Plant, 80m3/hr. Demineralization Plant (DM), and 250 m3/hr waste water treatment Plant.
The project was divided into three phases as written below.
I worked as responsible Engineer for the Technical proposal making and Basic design for Pretreatment (PT), Demineralization Plant (DM) and waste water treatment Plants (WWTP) for 2x660 MW “Jawaharpur Super thermal Power Plant”, Uttar Pradesh, India. Responsibilities included calculating Pre-treatment water, Demineralized water, waste water requirements including Basic design, Detailed design review, selection of vendor for supply of package items, finalization of specification of process equipment, process design and submission of preliminary documents to owner. I also interacted with Electrical, I&C, architectural and Procurement teams for carrying out the associated activates of the Package items.
Detailed engineering was done by Doosan’s Indian subsidy (Doosan Power system India). As a responsible engineer of Head office for water Treatment section, I also have the responsibility of the detailed design review to check for any technical issues and to avoid any cost impact to the company. I have the responsibility to report to head of engineering that this project will be completed on time without any delay.
