New desal plants to have tech that can withstand power fluctuations, sea turbulence

Chennai:
After Nemelli and Minjur desalination plants have been hit due to
technical glitches, plans are on to build new technology for the two
upcoming desalination plants so that they can acclimatise to local
conditions and power fluctuations, according to VATech Wabag chief
executive officer Rajiv Mittal.


Speaking to reporters on the sideline of TN CII Water Summit 2014,
organised by Confederation of Indian Industry, Mittal, whose firm was
entrusted with the construction of Nemelli desalination plant, said
that the
initial technology for the plant was designed not keeping in mind the
power fluctuations and turbulence nature of Bay of Bengal.

His comments come in the wake of the desalination plants operation
being hit due to power fluctuations and sea turbidity.

Defending the performance of the desalination plants, he said they
have the capacity to perform beyond 100 per cent. “Desalination plants
along the Arabian Sea are performing well as there is no issue of
rough seas and power fluctuations,” Mittal said.

Currently, we are trying to have this incorporated in the planned 150
MLD desalination plant in Nemelli and 400 MLD desalination plant which
is proposed close to Perur.

Interestingly, the 400 MLD desalination plant is awaiting the nod of
the Union government after which the Japan International Cooperation
Agency will undertake a feasibility study and decide whether to fund
the project or not, said JICA representative Itaru Chiba.

Earlier, Mittal said that a two-pronged strategy of desalination and
recycle and reuse of waste water will help Tamil Nadu achieve self
sufficiency in water. Desalination was a viable and stable option to
meet the water demand of the municipal segment and waste water reuse
and recycle would be the ideal choice to meet the demand of the
industrial and agricultural sectors.

N K Ranganath, Chairman, CII TN Water Summit 2014, and the Chairman
and Managing Director of Grundfos Pumps India Pvt Ltd, said that
Vision 2023 of Tamil Nadu  highlighted the important role water would
play in the overall development of the State
