As India is moving towards being a developed nation, it is constantly facing the issue of a deteriorating environment.

Rapid growth in industrialisation has increased the number of pollutants in our atmosphere.

Adding up to this is the diminishing of freshwater resources like groundwater, rivers, wells, etc.Water is one of the most important sources to survive.

Therefore, treating this situation with anything less than utmost seriousness can land us in deep waters.

Nature can treat naturally produced contaminants like human and animal waste.

However, the production of massive amounts of wastewater in today’s times cannot be managed by nature alone.Some of the effects of rising wastewater levels are:Lack of clean water for drinking and basic amenities.Presence of harmful toxic chemicals like lead and mercury which can lead to chronic health conditions in living organisms.Soil pollution.Contamination of groundwater and other natural sources of water.Wastewater treatment is the only best solution to tackle the water crisis we are facing today.

It’s 2019, as we near the status of a developed nation, it is drowning us towards a deteriorated environment.

Development is an important factor in any country’s socio-economic growth but it should be undertaken, keeping in check the impact on the environment.

An increased rate of industrialisation and urbanisation have infected our surroundings with many pollutants, with one of them being wastewater.

This wastewater has two sources - Industrial Wastewater Sewage from Domestic Households Industrial Wastewater can be classified into the following:Organic Industrial Wastewater - It comes from those industries which use organic substances for chemical reactions, such as: Textile IndustryFermentation FactoryMetal Processing IndustryTannery IndustryOil IndustryPharmaceutical Industry, etc Inorganic Industrial Wastewater - It comes mainly from those industries which use solid matter as their main raw material.

These include:Coal IndustrySteel IndustryNon-metallic Minerals Industry, etc Sewage from Domestic Households can be classified into the following:Yellow Water - human urineBrown Water - human faeces with flushed water Black Water  - human faeces mixed with urineGrey Water   - water used in other parts of the house except for toilets such as kitchen, washbasin, laundry and showersApproximately 22,900 million litres per day (MLD) of domestic wastewater and 13,500 million litres per day (MLD) of industrial wastewater is generated in India.

Therefore, much of it gets released into natural water resources such as rivers, ponds, lakes, streams, groundwater, etc making it unfit for consumption.

India is progressing and is competing with developed countries of today.

Apart from contributing to the rapid growth, our industries are also producing humongous amount of effluents that affect nature.

Which is why the need of wastewater treatment and recycling has now become a priority, out of everything else.Necessity of wastewater treatment plantsTwo of the main sources of contaminated water are sewage and industrial waste.

And to cope up with this rise especially considering limited freshwater resources like, rivers, wells and groundwater; our focus currently needs to be on the solutions to revive freshwater and methods to recycle and reuse water.The increasing level of wastewater, has more adverse effects.

When the wastewater is released untreated, it mixes with the other water sources and contaminates it.

This way, every water source gets polluted.This negligence needs to be eradicated and proper precautions to emit treated wastewater into the environment, should be taken.

Agriculture is one of the biggest sectors in India, making irrigation the largest consumer of water.

Another aspect is the pollution of groundwater and surface water by the agricultural use of untreated wastewater.

This further leads to abnormalities in the crop yield and the health of the farmers.

However, proper treatment can help in efficiently using the nutrient-rich wastewater for agricultural purposes, as well as the farmers’ livelihoods.Industrial SectorFor a long period of time, industries have discharged their waste without treatment into the water bodies.

Various highly advanced technologies like Disc Tube (DT) based RO system and Waste Heat Evaporator have made it possible for the Industrial wastewater to be recycled for reusable purposes.

According to a report by the United Nations, the Industrial sector is one of the major consumers of water and account for approximately 22% of global water use.

Every industry and manufacturing unit, has several pipes and routes installed for gallons of water to gush in.

The importance of water comes to the forefront when availability of water becomes a question, reusing and recycling the water becomes a necessity and meeting stringent norms of government before releasing wastewater to the environment is a need.

Knowing the capacity of the Treatment PlantWater treatment ensures that the production and manufacturing process of industries run efficiently, without causing unnecessary wear on machinery or becoming an incubator for deadly contaminants.

But with Roserve, the Wastewater Treatment Solutions and Equipment comes easy and becomes much more accessible with its Lease Structure.

For example, a pharmaceutical company would require wastewater solution for its chemical processes whereas an automobile company would require it for the effluents released from the metal, oils, grease, etc.But the gradual use of the wastewater equipment brings wear and tear.

This also depends on the various industries which release different intensity of chemical liquid to treat.

When thought of wastewater, what usually comes up in one’s mind is domestic wastewater and sewage.

After the screening, the water is pushed towards a grit chamber to skim out heavier solids like rocks, sand, gravel, and other materials, which are also sent to the landfill for disposal.

At this stage, the small yet heavy particles like vegetables or fruits, settle at the bottom (sludge), and lighter particles like fats and oils stay afloat, which are removed by skimming.Aeration & SedimentationThe wastewater after the screening, grit chambers and preliminary treatment, enters the secondary treatment process, the two step processThe first step is called the ‘aeration’.

Here, the wastewater is mixed with air and microorganisms which consume suspended organic matter such as food, human faeces and other organic matter.

In the second phase, the wastewater undergoes a yet another sedimentation process where the microorganisms - the activated sludge, are removed from the fairly clean wastewater.

The activated sludge is returned to the oxidation ditches to absorb more organic matter or is diverted to the digestion process for the waste is treated and dewatered to reduce pathogens and organic attraction like flies, mosquitoes, rodents etc.

Recently, by applying effective technologies into Reverse Osmosis and Nanofiltration systems, they have become more efficient and affordable for treating wastewater, brackish water, sewage and effluents for a wide range of industries.They are membrane filtration technologies which help in applying pressure to a liquid stream, flowing it through a semipermeable membrane in order to remove dissolved solids.

Their functioning resembles the existing other filtration technologies, yet they can remove even smaller particles, such as:Heavy metalsDissolved organicsOilPesticides Agricultural chemicals, etc.Both benefit from PretreatmentBy applying pretreatment to aqueous streams, both the membranes can have a long life span with relatively lower maintenance costs.

This is achieved by constantly allowing feed water to flow across the surface of the filtration membrane, which results in the rejection of problematic substances through the waste streams, rather than scaling onto the membrane.Both are used in place of conventional treatment systemsConventional wastewater treatment systems involve several steps, such as: CoagulationFlocculationSedimentationClarificationIon ExchangeFiltrationWhile they are effective in removing dissolved solids, they involve such a complex series of steps that often require a large area to function and investment.

On the other hand, Reverse Osmosis and Nanofiltration are widely accepted as they are compact, efficient, effective and environment-friendly.How Reverse Osmosis and Nanofiltration are different from each other?While they both are very similar in functioning, they can be differentiated based on the size of particulates that each is able to separate.

There are several applications of Reverse Osmosis, including Desalination, for generating potable water from seawater or brackish waterTreating industrial wastewaterNanofiltration - It helps in slightly coarser filtration than Reverse Osmosis, with the ability to remove particles as small as 0.002 to 0.005 μm in diameter.

The contribution of the MSMEs depends on various parameters that include the development of infrastructure, support from the government, the present market, various banking facilities, different government based policies and much more.In the category of manufacturing industries, MSMEs play an important role.

They come with their unique nature of contributing to employment of the country and requiring minimum amount of investment to function.The MSME’s PerspectiveCarrying out the daily operations using limited resources and capital, the MSMEs in the manufacturing segment of Industries are adding great value to the final output.

A lot of issues can be found when we take a closer look at these MSMEs.Investment and growth of the Manufacturing sector of MSMEThe last few decades have been substantial for the emerging MSMEs as a highly dynamic sector in the Indian economy.

Providing for large employment at lower capital costs when compared to large scale industries, the MSMEs help in development and industrialization of the rural belts and other backward areas.

Equity capital also has only limited access.

Outdated technology and innovation can be one of the core issues since the use of such technology impedes MSMEs’ competitiveness and growth.5.

Our lifestyle is a major subscriber of wastewater production and it’s all upon the wastewater treatment management that we are able to use clean water in our daily life.

Let’s take a look at how wastewater impacts the natural world.Natural water bodiesThe harmful untreated wastewater produced by industries are pushed to the seas, oceans, lakes and other water bodies.

Trillion gallons of sewage water from household and industrial sector are discharged in these water bodies, every year.

The requirement of wastewater treatment plant is hence vital in the bodies of freshwater, as the water from these bodies are used as a source for daily requirements.Disturbed groundwaterThe world is already going through a terrible clean water scarcity.

But when wastewater which is loaded with harmful chemicals and other effluents seeps into the ground, it mixes with the groundwater.

This disturbs the quality of water and renders as an unsafe water source for future use, at multiple locations.Our EcosystemsAlmost all ecosystems depend on water to flourish.

As the demand for water increases and new sources of supply become more expensive to develop, there is an increasing need to use water more than once during the hydrological cycle.

The development of wastewater reclamation and reuse in many countries is related to looming water scarcity, water pollution control measures and protection of the aquatic environment.

There is also the need to obtain alternative water resources for a growing population.Reclaimed Water It is the wastewater that has been thoroughly treated to remove harmful organisms and substances, such as bacteria, viruses and heavy metals, so it can be reused.

By using reclaimed water, we can conserve freshwater supplies and provide a solution for a sustainable environment.

It can be safely used for a wide variety of purposes, such as:landscape irrigation for golf courses, parks, highway medians, playgrounds and residential propertiesgroundwater rechargeindustrial uses such as cooling; fire protectionwetlands creation, restoration and enhancementReclamation views wastewater as a resource to be put to productive use, rather than as a waste to be disposed of.

The degree of treatment depends on the purpose, it will serve.Agricultural ReuseWhile most of the constituents in wastewater are treated as pollutants, some constituents are nutrients, such as nitrogen, phosphorous, and potassium.

Our planet is suffering from global warming and is facing its harmful consequences sooner than ever before.

What’s more shocking is that we’re expecting a jump of 2-5 degrees Celsius, over the span of 30 years.

But in this situation of crisis, what mostly gets overlooked, is the impact of global warming on wastewater treatment.

Inundated Water SuppliesAs the glaciers and ice in the northern hemisphere melt, the sea level continues to rise.

These biological reactions lead to release of oxygen which causes rusting and corrosion of pipes.

This calls for a repeated replacement of equipment due to increased wear & tear.These reactions often cause the temperature to rise and hence causes evaporation too.

Mostly, the treatment of wastewater from small scale business and industries, is a process taken care of by the local government.

But institutions like schools and other small scale industries in isolated locations, need their own treatment to avoid fines/fees from environmental agencies.

These isolated locations often have too much water to treat that makes it necessary for them to own a wastewater treatment plant.The primary operational problem the small-scale wastewater treatment plants face, is the flow variability.

This can be resolved by adding storage tanks, but a better solution is to change the process & make it more scalable.

The smaller version of large plants and plants using membrane bioreactor technology can operate continuously, while still delivering high-quality discharge.Roserve leases wastewater treatment equipment to a range of enterprises and industries.

As per the Ministry of MSME’s Annual Report for FY18, there were a total of 6.33cr MSMEs in India, employing about 11cr people, representing more than half of India’s workforce.

Further, MSMEs accounted for 30% of India’s GDP, 45% of India’s total manufacturing, and 40% of India’s exports in FY18.

The sector has consistently maintained a growth rate of over 10%.

Manufacturing industries which are a part of the MSME sector face problems that goes beyond their reach in terms of Wastewater management across their production facilities but are bound by the mandatory norms of the State and Central Pollution Control Board’s (PCB’s) - Setting up of Wastewater Treatment Plant to ensure discharge as per PCB normsIndustrial wastewater treatment equipment installation costs are typically very heavy which weigh on the pockets of the businessmen, who can barely afford to run the manufacturing units.

A backburner even for a large-scale industry, the capital investment becomes a major step and a big decision to take.In most of the manufacturing industries, the final output or the finished product produces fair amount of wastewater, which can be either recycled or reused in the same process again.

By treating the industrial effluent of large-scale industries and MSMEs, ROserve can help the companies optimize cost on the extraction of groundwater while at the same time help them in meeting the PCB norms through recycle and reuse of that water again.The unavailability of cost-effective solutions in the market makes many manufacturing units and multiple other industries difficult to run and expand.

By treating the industrial effluent of large-scale industries and MSMEs, ROserve can help the companies optimize cost on the extraction of groundwater while at the same time help them in meeting the PCB norms through recycle and reuse of that water again.The unavailability of cost-effective solutions in the market makes many manufacturing units and multiple other industries difficult to run and expand.
