Overview of the project

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

Background

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.

Objective of the Project

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.

Roles & Responsibilities

  • Taking permissions from the government department for collecting samples of leachate from DadduMajra Landfill site and Hand pump water from near the landfill site
  • Literature survey from the research papers to plan the work to be done for the Master’s thesis
  • Preparation of the methodology of the experimental work
  • Arrangement of experimental setup in the Environmental Engineering Laboratory
  • Carrying our experimental runs
  • Analyzing the data collected from the experimental runs
  • Preparation of the results and discussion chapter based on experimental analysis

Since I was the only project patron so I managed all the project management by myself.

Background

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.

Objective of the Project

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.

Roles & Responsibilities

  • Preparing the process calculations and checking the calculations for the process design prepared by the Technical Manager
  • Development of the P&ID and GA drawings. For the drafting purpose one draftsman was allocated to me.
  • Preparing technical specifications for the techno commercial proposals from specialized sub vendors like centrifuge and process equipment suppliers. I was part of the Suez TechnicalExpert’s team.
  • Reviewing the technical proposal submitted by specialized sub-vendors and communicating with their technical staff for the technical correction work.
  • Preparing the technical data sheets which are to be submitted with the technical proposal.
  • Preparation and correction of the design report to be submitted to the project owner’s consultant for review.
  • Preparation of the support technical documents to be submitted to owner’s engineer for review.
  • Preparation of all the documents to handover from Technical proposal side to the Project execution team after we had a successful award of contract.
  • I have selected the equipment for the plant which was entirely environmental friendly with Minimum carbon emission in any form.

Overview of the project

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

Background

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.
