ISO 9001:2015 CERTIFIED COMPANY

The Beginning

Energreen Solutions was first conceived by a group of technocrats who were motivated to arrest the wide spread environmental degradation due to industrialization, urbanization and agricultural expansion. With developmental options being designed to minimize damage to the environment, we initiated a business that could effectively manage the unavoidable exploitation of nature by using technological know-how to recycle and reuse precious resources. In the process, we generated wealth not only for ourselves, but also for our clients, while ensuring the health and well-being of the communities we operated within. Our first venture, launched in 2005, was an Organic Waste Management project, which doubled as a renewable energy production unit, using 500kgs of kitchen/canteen waste from the hostel of a residential school. Technical success and unalloyed customer satisfaction was the reward.

Company Profile

The success of this project, bolstered by its proven technological effectiveness and consistently improving results over a span of 3 years, encouraged us to further our mission to safeguard the environment. ENERGREEN SOLUTIONS was formally registered in February, 2008, under the leadership of our founder, Mr.Biju.V, who graduated with B.Sc in Forestry and holds a Post Graduate Diploma in Waste Management. His passion for the cause of environmental conservation and his flair for merging business profits with larger objectives concerning the common good, have been instrumental in steering the formation and growth of Energreen Solutions.

We believe that the key to customer satisfaction in a technology-based business is contained in the composite advantage of having allied technical expertise, the will to learn more on a daily basis and a spirit of team work sustained by commitment to a culture of concern and uncompromising quality. We regularly participate in seminars and workshops to update ourselves with developments and innovations in our field of business and to stay ahead of the competition.

All our projects are empowered by this vision, making them invariably cost effective and value-enhancing propositions for clients, in the long run.


Our Business Philosophy

The reality of an imminent ecological crisis centered in the availability of potable water is an anticipated predicament. As responsible denizens of this planet, it is the duty of every individual and every corporate entity to act in constructive ways towards contributing to the objective of environmental conservation not only because Nature needs to be protected but also because we ourselves are, inevitably, going to be the hapless victims of the disaster that is predicted.

Technology has spawned immense developmental activity across the world; and, unfortunately, triggered significant damage to the environment; in the process. At Energreen Solutions, we are confident that the same technology can be harnessed to undo the damage and steer a path towards sustainable development, since we cannot deny the exigency of development itself.

We have taken a pledge to promote the cause of clean water and sanitation, which is the 6th of 17 sustainable development goals proposed by the United Nations as the objectives that should drive ‘governments, the private sector, civil society and people’. We believe that conservation of natural resources can be achieved without suspending development. Commitment to a pragmatic and viable vision of technology-aided measures, to leverage the possibilities inherent in sustainable development projects, is our answer to the modern dilemma of ‘Development at what cost’?



There are numerous methods of treating water and wastewater, depending on contamination levels and purpose of end use.

Water ‘purification’ refers to the final outcome of one, or a series, of ‘treatment’ processes that are employed to produce drinking water that is pure enough for the most critical of its intended uses; human consumption. The more contaminated the source water, the more will be the treatment processes it has to be subjected to, before ‘purity’ is achieved.

Water ‘treatment’ involves the use of scientific methods to attain specified parameters of water quality, as required by the needs of particular industries or equipment. The parameters are determined by the unique standards of water quality required in each particular industrial activity. Better product quality is the objective of treating water to achieve the desired parameters.

‘Wastewater treatment’ is the process that removes the majority of contaminants from wastewater or sewage or effluent and produces ‘treated water’ suitable for disposal to the natural environment after the separation of ‘sludge’. Wastewater needs to be brought down to acceptable parameters as specified by the Central/State Pollution Control Board, before it can be disposed to the natural environment. This water can be further treated to produce water of any other specified grade or quality.

Water purification – Physical Methods.
Physical water ‘treatment’ is primarily a filtration process. FILTRATION uses a purification instrument to remove solids or insoluble particles from liquids. There are several different filtration techniques, the simplest being SCREENS. Other typical filters are comprised of a tank/filter vessel, the filter media and a controller valve, to enable backflow. Depending on the media used, these are termed SAND FILTER, IRON REMOVAL FILTER, ACTIVATED CARBON FILTER, WATER SOFTENER etc.

A more sophisticated method is CROSS FLOW Filtration, where membranes are used to filter water. There are several different membrane filtration techniques and they are termed MICRO FILTRATION, ULTRA FILTRATION, NANO FILTRATION AND REVERSED OSMOSIS (R.O). Techniques are chosen depending on the kind of compounds that need to be removed from the water and the particle size of these. Membrane Bio Reactor or MBR system is a cross flow filtration technology used to improve wastewater quality.

There are CARTRIDGE FILTRATION units which consist of fibers. They generally operate most effectively and economically on applications having contamination levels less than 100ppm. For heavier contamination removal applications, cartridges are normally used as a final polishing filter.

Water Treatment– Chemical Methods
Chemical purification of water can be achieved through various methods. The choice of method will depend on the kind of contamination in the water. Some of the chemical purification techniques are explained below:

1. Chelating agents are added to water, in order to prevent the negative effects of hardness.
2. Oxidizing agents are added to act as a biocide, or to neutralize reducing agents.
3. Reducing agents are added to neutralize oxidizing agents,

Clarification : Clarification is a multi-step process to remove suspended solids. First, coagulant chemicals are added. Coagulants reduce the charges of ions, so that solids accumulate into larger particles called flocs. The flocs then settle by gravity in settling tanks or are removed as the water flows through a gravity filter.

Deionization and softening : Deionization is commonly achieved through ion exchange. Ion exchange systems consist of a tank with small beds of synthetic resin, which is treated to selectively absorb certain cat-ions or an-ions and replace them with respective counter-ions. The process of ion exchange lasts until all available spaces are filled up with ions. The ion-exchanging device then has to be regenerated by infusing suitable chemicals. One of the most commonly used ion exchangers is a water softener

Disinfection : Disinfection is one of the most important steps in the purification of water. It serves the purpose of killing the undesirable microorganisms present in the water. Therefore, disinfectants are often referred to as biocides. There are a variety of techniques available for disinfection such as, chlorine disinfection, UV disinfection and Ozone disinfection.

pH-adjustment : Depending on existing raw water pH, it is brought up or down to neutral ( 7 ) or between 7 and 7.5, using appropriate chemicals.

Distillation : Distillation is the method of collecting evaporated water vapor, after boiling the wastewater. With a properly designed system, removal of organic and inorganic contaminants and biological impurities can be achieved, because most contaminants do not vaporize. Water will then pass to the condensate and the contaminants will remain in the evaporation unit.

Electro dialysis : Electro dialysis or Electro-coagulation is a technique that employs electrical current and special membranes, which are semi permeable to ions, based on their charge. Membranes that permeate cat-ions and membranes that permeate an-ions are placed alternately, with flow channels between them, and electrodes are placed on each side of the membranes. The electrodes draw their counter ions through the membranes, so that these are removed from the water.


Water Treatment - Biological Method
Biological water purification is performed to lower the organic load of dissolved organic compounds. Microorganisms, mainly bacteria, do the decomposition of these compounds.

There are two main categories of biological treatment: AEROBIC TREATMENT and ANAEROBIC TREATMENT. The Biological Oxygen Demand (B.O.D.) defines the organic load. In aerobic systems the water is aerated with compressed air (in some cases merely oxygen), whereas anaerobic systems run under oxygen free conditions.

Activated Sludge Process ( ASP ) was the most common technology adopted earlier and based on this fundamental principle, several advanced technologies developed. MBR (Membrane Bio Reactor) technology was initially developed in the late 60’s, and its use gained momentum from the early 1990’s. This technology is primarily used for the treatment of wastewater. It is a combination of a membrane process like micro-filtration or ultra-filtration and the application of a suspended growth bioreactor.

MBBR (Moving Bed Bio-film Reactor)technology is preferred for the improved reliability and simplified operation when compared to the traditional wastewater treatment systems. This technology makes use of many (around thousands) of polyethylene bio film carriers that operate in a mixed motion within an aerated wastewater treatment basin. The protected area of the bio film and apt conditions help in growing and thriving of the bacteria culture. An aeration grid is situated at the bottom of the reactor that supplies oxygen to the bio film. It helps in keeping the bio carriers suspended and they get completely mixed with the reactor. The bio film on the carriers break down the wastewater and the treated water comes out through a grid or sieve in which the bio carriers are retained.

ORGANIC WASTE MANAGEMENT

TheBusiness Advantage in Propagating Organic Waste Management

Changing trends in business and political attitudes, all around the world, encourage, recognize, appreciate and reward concerns for environmental protection, climate change and global warming.

Organic waste is such a potent source of sustainable gain that we were motivated to devise a system, which is capable of tackling two of the greatest problems of this century – organic/bio waste accumulation and the energy crisis –at one stroke! Our Bioreactors or Biogas Plants, promising multilevel benefits and a permanent solution to the problem of organic waste disposal, at the same time, are a convenient, one-time investment, entailing negligible maintenance and running cost. These plants convert canteen (cooked food) / kitchen (un-cooked food) waste into thermal energy (burning/cooking- gas), electrical (gas being source in generator) energy and organic manure.

A well maintained Biogas Plant can solve most problems related to waste management and at the same time, generate income from multiple sources, including power generation and organic manure.

BIO GAS PRODUCTION METHODOLOGY

When organic matter is brokendown in the absence of air by microbial activity, Biogas is formed. It is normally a mixture of different gases and mainly of Methane and Carbon Dioxide, apart from traces of Hydrogen Sulphide, Hydrogen, Carbon Monoxide etc. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste (cooked or uncooked). It is a renewable energy source and in most cases, exerts a very small carbon footprint.

Biogas can be produced by anaerobic digestion with anaerobic bacteria, which digest material inside a closed system, or by fermentation of biodegradable materials. The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen. This energy release allows biogas to be formed. This gas can be used as fuel; or for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.
