Water purification plant at Soolai nearing completion
purification plant on the verge of completion at Soolai in the city will
draw broad attention of dyeing, bleaching, tanning and printing units
in the district to the unique technology to be adopted for conversion of
effluent into food grade water.
Advanced FPSTAR technology
developed by a Bengaluru-based laboratory is to be deployed for
conversion of the waste liquid into water fit for consumption.
The
model plant that would use Aquatron Boomtube Resonator is stated to be
the first of its kind facility in the state to convert sewage wastes and
industrial effluent into food grade water.
As many as 40 to 50
industries have made substantial financial contributions at the
initiative of Olirum Erodu Foundation for establishing the model plant.
Totally,
Rs. 1.8 crore is the estimate for the model plant with capacity to
treat 2.4 lakh litres a day with two similar units: one to treat sewage
waste from Pichakaranpallam Odai and the other to process effluent from
tanning, dyeing and bleaching units brought in lorries.
The
civil work has been completed and the machinery has also arrived.
Installation would consume duration of at least two weeks, and trial run
would be conducted thereafter.
In the meantime, the stakeholders
of the model plant have reportedly approached the IIT Madras requesting
for constitution of a technical committee to validate purity level of
the treated water, and determine utility of the minimal sludge generated
in the process as manure.
Once the purity is confirmed,
industries will be encouraged and facilitated to form clusters and
establish more number of such plants in geographical proximity,
Pollution Control Board sources said.
District Collector S.
Prabakar, who carried out an inspection on Wednesday, said the 545
dyeing, bleaching and printing units, and 34 tanning units were required
to adopt Zero Liquid Discharge technology.
The treatment cost under the new technology will be much lesser. Also, only two % of the waste precipitates as sludge, he said.
