Water purification plant at Soolai nearing completion

The Pollution Control Board (PCB) is confident that the model water 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.

Why don’t we reduce, reuse & recycle to conserve water

CHENNAI: While the country is blessed with some of the largest river systems in the world, water scarcity is fast becoming our biggest woe. The increasing water need of the growing population has led to a decline of per capita availability of fresh water from 3,000 cu m to 1,123 cu mover the past 50 years. In urban areas, the situation is worse as only one-third of homes have drinking water facility from a treated tap source, and only one-fifth have closed drainage connectivity. The demand of 135 litres per capita daily (LPCD) is more than three times the rural demand of 40 LPCD.

On World Water Day, in line with the United Nations theme, “Why Waste Water?” we should also take a pledge to reduce and reuse water. Given that water is mainly used for sanitation across the country, smart bathrooms and toilets are the way to water management solutions. Advanced technology and water saving habits must be adopted. Innovative products like digital faucets, electronic toilets, waterless urinals come with smart function and latest designs, thus making them a great fit for any modern day bathroom. Water used in showers, toilets, and sinks account for approximately 3/4th of the water used in our daily lives and hence bathroom is a great place to start making water conscious decisions this World Water Day.

By adopting these small changes, we will not only become water conservationist and save the planet’s most precious natural resource but also save on our water bill. While a leisure bath is needed once in a while, spending less time in the shower is the first step towards saving water. For keeping track of time, you carry the phone into the bathroom and time yourself by how many songs play while you are in there. To save water, limit the shower time to a single song. Using a bucket is always better. However, adjusting the water temperature while your bucket is filling instead of waiting for them to fill and then discarding the water for it being too cold or hot saves not only water but also your time.

Constant tap drips can lose many gallons of water eacch day and should be immediately fixed. If an immediate action is not feasible, keep a bucket under it and mop the house next day using that water. One of the major leaks that go unnoticed is a toilet flush. A quick trick to check it is by putting a dye or food colouring into the tank. In the case of a leak, the colour will appear in the bowl without flushing. Additionally, refrain from flushing things down the toilet to dispose them off. Make a habit of throwing waste in the garbage bin.

If you are remodelling a bathroom, you can install water saving products. The best technologies available in the market are: waterless urinals — the automated, waterless urinals have elevated the hygiene standards in the ever-evolving sanitary ware industry. The flush free urinal systems work without water, making it the most advanced product in the category. The products available are built in such a way that they do not require any power or liquid barrier for the closure of drainage that makes it versatile, thus saving two very important aspects of today’s life — water and electricity.

This comes with inbuilt air perfume thus preventing foul smell. Cold start faucets — the revolutionary technology of digitised toilets have changed the way customers see hygiene in the bathroom space. Cold start faucet is an innovation designed for sustainability, with water and energy saving capability and zero CO2 emissions. It allows you to use cold water for daily bathroom rituals with a lever in the centre. In addition to saving water, you’ll be saving energy, as it prevents the boiler from firing up when not needed. Washbasin and water closet — a never-before product in terms of design and solutions, the washbasin and water closet is a perfect example that reflects “water-reuse technology”.

It reuses waste water from the washbasin to fill the toilet cistern. An integration of the expression of innovation and design, perfect for saving water and space. Steam showers instead of water showers — power of steam helps keep clean and are also very water efficient. They use less water than a traditional shower and are very relaxing to use. Flow limiters and aerators — adding a flow limiter to a shower system allows you to achieve more sustainable water consumption without affecting comfort levels. It limits the flow of water and, additionally, boosts comfort giving the body a pleasant tingling sensation. Other advanced features: Additional features like dual flush WCs, low water consumption urinals, water and energy saving faucets are favoured all over the world and should be adopted by everyone.

Wastewater treatment plant at Soolai slated for completion in May

LASTING SOLUTION:Work on establishment of waste water treatment plant began at Soolai in Erode on Friday.M. GOVARTHANM.GOVARTHAN ;M.GOVARTHAN - M_GOVARTHAN  

The plant with two units to have a capacity to treat 2.4 lakh litres

The work on the model treatment plant that was initiated at Soolai to process sewage waste and industrial effluent a few days back is slated for completion in May.

The foundation was laid by School Education Minister K.A. Sengottaiyan in the presence of Environment Minister K.C. Karuppannan, District Collector S.Prabakar, senior officials of Pollution Control Board, and functionaries of Olirum Erodu Foundation.

The plant with two units will have a capacity to treat 2.4 lakh litres: sewage waste from Pichakaranpallam Odai and effluent from tanning, dyeing and bleaching units to be brought in lorries in equal proportions.

Of the Rs. 1.8 crore required for machinery, Olirum Erodu Foundation had mobilised Rs.92 lakh from industries, and the rest has been provided by the Government.

Erode East MLA Thennarasu has consented to provide Rs. 40 lakh from constituency development fund for completing the civil works, sources said.

Conversion of the waste liquid into food grade water is the highlight of the advanced FPSTAR technology developed by a Bengaluru-based laboratory. The model plant using Aquatron Boomtube Resonator is touted to be the first plant in the State to convert sewage wastes and industrial effluent into food grade water.
