Nisha Dhankar, Managing Director, ABL Roots Blowers Pvt. Ltd., “Since the urban areas of many developing countries are growing rapidly, ecological sanitation systems must be implemented that are sustainable and have the ability to adapt and grow with the community’s sanitation needs.”

“The government needs to involve stakeholders including policy makers, politicians, researchers and entrepreneurs of water resources from India as well as global expertise to discuss strategies for managing the demands and supplies in the right manner.”

 

In the last couple of years changes have been occurring in the wastewater chain. These changes are due to tighter regulations on one hand and the fact that wastewater infrastructure needs major repairs on the other. This created a new trend in wastewater collection and treatment systems. Instead of considering wastewater as waste, it is now more and more seen as a raw material carrier.

Water is one of the world’s most valuable resources, yet it is under constant threat due to climate change and resulting drought, explosive population growth, and waste. One of the most promising efforts to stem the global water crisis is industrial and municipal water reclamation and reuse. Thus, water recycling is the reuse of treated wastewater for beneficial purposes such as agricultural and landscape irrigation, industrial processes, toilet flushing, or replenishing a groundwater basin (referred to as groundwater recharge). Water reuse allows communities to become less dependent on groundwater and surface water sources and can decrease the diversion of water from sensitive ecosystems. Additionally, water reuse may reduce the nutrient loads from wastewater discharges into waterways, thereby reducing and preventing pollution. This ‘new’ water source may also be used to replenish overdrawn water sources and rejuvenate or reestablish those previously destroyed. In order to determine the appropriate treatment system, the developer must consider the area’s climate, topography, and socioeconomic factors.

The uncontrolled disposal to the environment of municipal, industrial and agricultural liquid, solid, and gaseous wastes constitutes one of the most serious threats to the sustainability of human civilization by contaminating the water, land, and air and by contributing to global warming. With increasing population and economic growth, treatment and safe disposal of wastewater is essential to preserve public health and reduce intolerable levels of environmental degradation. In addition, adequate wastewater management is also required for preventing contamination of water bodies for the purpose of preserving the sources of clean water. Effective wastewater management is well established in developed countries but is still limited in developing countries. In most developing countries, many people lack access to water and sanitation services. Collection and conveyance of wastewater out of urban neighborhoods is not yet a service provided to all the population, and adequate treatment is provided only to a small portion of the collected wastewater. In slums and peri-urban areas throughout the world, it is common to see raw wastewater flowing in the streets. The inadequate water and sanitation service is the main cause of diseases in developing countries.

Considering the expected population growth and the order of priorities in the development of the water and sanitation sector in developing countries – water supply and sewerage first, and only then wastewater treatment—as well as the financial difficulties in these countries, it cannot be assumed that the current low percentage of the coverage of wastewater treatment in these countries will increase in the future, unless a new, innovative strategy is adopted and affordable wastewater treatment options are used.

A key component in any strategy aimed at increasing the coverage of wastewater treatment should be the application of appropriate wastewater treatment technologies that are effective, simple to operate, and low cost (in investment and especially in operation and maintenance). Appropriate technology processes are also more environment-friendly since they consume less energy and thereby have a positive impact on efforts to mitigate the effects of climate change.

The demand for fresh water in India has been continuous to boost at a rapid pace primarily due to the growing population, increasing urbanisation and the steady economic growth. The municipalities and industries are continuously investing substantial money in water and wastewater improvement, creating ample opportunities for water and wastewater treatment equipment technology in India.

Due to over-exploitation of water resources in coastal areas, seawater is often mixed with groundwater in some cities like Chennai and Mumbai, making groundwater high in salt content. The reducing per capita availability of water and deteriorating water quality has forced the country to look for sustainable and effective water technologies to provide clean and quality water.

As haphazard urban development continues in India, infrastructure to support the growth is being stretched to its breaking point. Thus, nowadays, water management is becoming an inherent part of planning and development.

The water and wastewater treatment market in India is in the growth phase and has immense untapped potential.

Before purchasing a water or wastewater equipment unit, purchasers should test their water to be certain that treatment is needed and that the equipment being selected is appropriate for the problem. Hence, an end user appoints a technical consultant to give recommendations to the Engineering, Procurement and Construction (EPC) contractors and equipment suppliers. Some end users appoint the equipment and component suppliers with their own technical team, while others outsource it to an EPC contractor. The preferred supplier is the one who provides a one-stop solution with good operations and maintenance support.

Industries and applications such as wastewater treatment, pneumatic conveying, power generation, food and beverage, pharmaceuticals, chemicals, pulp and paper, textiles, cement, and general manufacturing will highly benefit from the energy efficiency and high reliability of ABL Blowers range of oil-free air solutions.

Our compressors/blowers are positive displacement units, whose pumping capacity is determined by size, operating speed and pressure conditions. It employs two Twin Lobe impellers mounted on parallel shafts, rotating in opposite direction within a casing closed at the ends by side plates. As the impellers rotate, air is drawn into one side of the casing and forced out of the opposite side against the existing pressures. The differential pressure developed, therefore, depends upon the resistance of the connected system. The Blowers, being positive displacement type, do not develop pressure within the casing but the discharge pressure depends upon the system resistance / back pressure. Effective sealing of the compressor inlet area from the discharge area is accomplished by use of very small operational clearance, eliminating the need of any internal lubrication of the lobes.

Some of the common applications are listed below:

 

 

Water Treatment Plants for backwashing of filter/mixed beds

 

Effluent Treatment Plants for diffused aeration and agitation of effluent

 

Sewage Treatment Plants for diffused aeration and agitation of sewage

 

Cement Plants for blending, aeration, fluidization and conveying

 

Aquaculture for maintaining the dissolved oxygen level

Wastewater treatment and water recycling or reclaiming for reuse has prevailed for quite some time in other parts of the world such as Europe and United States of America. However, with the growing demand for potable water, the rate of using reclaimed water is gaining pace in the Asia Pacific markets, especially in India. Recycling of water and wastewater treatment involves a combination of technologies to treat the water and make it reusable or attain a safe standard for disposal. Technologies such as nanotechnology, desalination and membranes have been widely used for water treatment depending upon the quantity and quality of water/ wastewater and the available funds as per the specific use. As energy-efficient processes are the need of the hour, forward osmosis, hybrid desalination and solar desalination will gain importance over the years.

In recent decades, compliance with Government wastewater quality requirements has been the primary driver of industrial wastewater treatment programs in India. Aeration systems and blowers search for energy efficient methods and processes. Measurement control and automation are the highest increase in the total value chain for aeration systems. The market is highly fragmented. Cost, high expertise, prior experience and brand equity are critical competitive factors in the Indian market. For huge municipal and industrial projects there is a pre-bidding process and hence high expertise and prior experiences are critical factors. Companies that offer energy-efficient solutions at competitive costs are likely to take a central position in Indian water and wastewater treatment market.
There are various opportunities in the Indian water and wastewater treatment market, but the industry has to also overcome several challenges. The biggest of all is the slow pace of implementation of policy reforms in India. But, with the business environment improving, one can expect several initiatives aimed at water supply and sanitation. The Government is also planning to increase desalination projects along the coastal areas. Different end-user segments offer varied potential for the water and wastewater treatment markets. Power sector is a promising end-user segment for both water and wastewater treatment.
