Prof Dr Md. Shohidullah Miah: Textile Wastewater Treatment

Title: Involved with research on Textile Wastewater Treatment by using UASB and Bio-filtration process

 Concept of UASB Process for Textile Wastewater Treatment:

The anaerobic process is a high quality treatment process. It has several advantages such as low cost, simple operational mechanism and the ability to produce less excess sludge. The organic matter can be converted into energy in the form of biogas. Therefore, the anaerobic process is beneficial in terms of environmental protection and economic viability. In Bangladesh, the anaerobic process is completely new. It can reduce environmental pollution and generate energy in biogas from wastewater. The anaerobic process occurs in the absence of oxygen and converts the organic compound into CH4 and CO2. Therefore, anaerobic treatment is an alternative source of bio-energy and bio-fertilizer as well as reducing environmental pollution. Anaerobic digestion is a promising process for the treatment of wastewater in tropical and subtropical countries. Under the UASB process the organic compounds digested under anaerobic conditions produce: methane, carbon dioxide, hydrogen, nitrogen and hydrogen sulphide, etc.The UASB system is a high rate treatment process. Organic loading rate is the most important for determining the shape and size of the reactor.The UASB successfully uses mesophilic temperature ranging from 25-39°C. The basic concept of UASB is the fact that flocks of anaerobic bacteria will tend to settle under gravity, when applying a moderate up-flow velocity.

This UASB process has been tested at Mascom Composite Limited, Kashempur, Gazipur, Radiance Group Limited, Ashulia, Savar and AmaSyntaxLimited, Kashimpur, Gazipur.

The Beneficial Effects of UASB Process:

i).   High rate of anaerobic treatment capacity

ii). Treatment efficiency under mesophilic temperature conditions

iii). High organic strength wastewater can be treated

iv). Relatively simple and low operation costs

v). High organic removal efficiency

vi). Bio-energy benefit can be obtained through biogas production

vii). Excess sludge production is very low compared to conventional treatment processes.
