Our Philosophers and Members
Our Philosopher: Acharya Srimat Swami Pranavananda Ji Maharaj
The advent of His Holiness, Acharya Srimat Swami Pranavananda ji Maharaj was in 1896, in the village Bajitpur (Bangladesh) of undivided India. ,'BINOD', as was called in his childhood days, was often found to be immersed in serious thoughts that culminated into deep meditation, aimed at 'Self Emancipation' and 'Upliftment of Human Beings', through spiritual development and selfless Services. As a brahmachari, he spent countless hours in meditation, spiritual trances and Seva (service to people).
Our Gurudev: Sri Gobinda Ji Maharaj
The advent of His Holiness, Gurudev Sri Gobinda Ji Maharaj was in 1965, in the village Bhabwanipur (Chaital-North 24 Parganas) of West Bengal, India. The Gurudev, as believed by many was an incarnation of Lord Shri Krishna. His parents were undergoing untold miseries in a remote corner of rural Bengal. As an Ardent devotees of Lord Shri Krishna, they undertook hard penance and rigorous austerities to propitiate the Lord who in a dream, conferred upon them a great boon by incarnating Himself as their son.

A great disciple of work, down to earth with a basic simplicity human devoted his life to a transparent work in the field of Environmental Research, human development and king maker of Inventor.
Chairman of the task force on total sanitation campaign and member of the arsenic task force, said the national rural drinking water supply programme, which was scheduled to be implemented from 2008 to 2012, got under way in April 1 this year. "In West Bengal, only 35% of the rural population has been covered by 1,150 piped water supply schemes, while the remaining 65% is covered by around 5,00,000 spot water sources like tube wells. By 2012, 50% of the rural population is likely to be covered by piped water supply schemes," he added. NGOs need to be involved in providing an alternative safe drinking water supply system, he said, adding, "We have to ensure coordination between the bodies at the state level to further develop the system."
More than a human being he is searching and marching towards always a new procedure and development in the field of Water Pollution and accurate standardization level.

::Water & Waste Water::
The treatment of solid wastes is a key component of waste management. Different forms of solid waste treatment are graded in the waste hierarchy. Waste managementis the collection, transport, processing or disposal, managing and monitoring of waste materials. The term usually relates to materials produced by human activity, and the process is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is a distinct practice from resource recovery which focuses on delaying the rate of consumption of natural resources. All wastes materials, whether they are solid, liquid, gaseous or radioactive fall within the remit of waste management. Waste management practices can differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers. Management of non-hazardous waste residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator subject to local, national or international controls.
:Waste water treatment:
Agricultural waste water treatment: Agricultural wastewater treatment is treatment and disposal of liquid animal waste, pesticide residues etc. from agriculture. Industrial wastewater treatment: Industrial wastewater treatment is the treatment of wet wastes from manufacturing industry and commerce including mining, quarrying and heavy industries. Sewage treatment: Sewage treatment is the treatment and disposal of human waste. Sewage is produced by all human communities and is often left to compost naturally or is treated using processes that separate solid materials by settlement and then convert soluble contaminants into biological sludge and into gases such as carbon dioxide or methane. Wastewater, also written as waste water, is any water that has been adversely affected in quality by anthropogenic influence. Municipal wastewater is usually treated in a combined sewer, sanitary sewer, effluent sewer or septic tank. Sewage is the subset of wastewater that is contaminated with feces or urine, but is often used to mean any wastewater. Sewage includes domestic, municipal, or industrial liquid waste products disposed of, usually via a pipe or sewer (sanitary or combined), sometimes in a cesspool emptier. Sewerage is the physical infrastructure, including pipes, pumps, screens, channels etc. used to convey sewage from its origin to the point of eventual treatment or disposal. It is found in all types of sewage treatment, with the exception of septic systems, which treat sewage on-site. Radioactive waste treatment: Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment. Radioactivity diminishes over time, so waste is typically isolated and stored for a period of time until it no longer poses a hazard. The period of time waste must be stored depends on the type of waste. Low-level waste with low levels of radioactivity per mass or volume (such as some common medical or industrial radioactive wastes) may need to be stored for only hours or days while high-level wastes (such as spent nuclear fuel or by-products of nuclear reprocessing) must be stored for a year or more. Current major approaches to managing radioactive waste have been segregation and storage for short-lived wastes, near-surface disposal for low and some intermediate level wastes, and deep burial or transmutation for the high-level wastes. A summary of the amounts of radioactive wastes and management approaches for most developed countries are presented and reviewed periodically as part of the International Atomic Energy Agency (IAEA) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.
:Black water:
Black water is a term dating to at least the 1970s used to describe wastewater containing fecal matter and urine. It is also known as brown water, foul water, or sewage. It is distinct from grey water or sullage, the residues of washing processes. Water coming from domestic equipment other than toilets (e.g., bathtubs, showers, sinks, washing machines,) is called grey water and it is preferred to be kept separate from black water (which comes from toilets) to reduce the amount of water that gets heavily polluted. Separation of black water and grey water nowadays happens with all ecological buildings. Especially in autonomous buildings, the separation is always present. It is also commonly used on recreational vehicles which feature grey water holding tank and a blackwater holding tank. Black water contains pathogens that must decompose before they can be released safely into the environment. It is difficult to process black water if it contains a large quantity of excess water, or if it must be processed quickly, because of the high concentrations of organic material. However, if black water does not contain excess water, or if receives primary treatment to de-water, then it is easily processed through composting. The heat produced by naturally occurring thermophilic microorganisms, will heat the compost to over 60 degrees C, and destroy potential pathogens. The compost is eventually reduced to safe fertilizer after about one year.
:Treatment:
Treatment: There are numerous processes that can be used to clean up wastewaters depending on the type and extent of contamination. Most wastewater is treated in industrial-scale wastewater treatment plants (WWTPs) which may include physical, chemical and biological treatment processes. However, the use of septic tanks and other On-Site Sewage Facilities (OSSF) is widespread in rural areas, serving up to one quarter of the homes in the U.S. The most important aerobic treatment system is the activated sludge process, based on the maintenance and recirculation of a complex biomass composed by micro-organisms able to absorb and adsorb the organic matter carried in the wastewater. Anaerobic processes are widely applied in the treatment of industrial wastewaters and biological sludge. Some wastewater may be highly treated and reused as reclaimed water. For some wastewaters ecological approaches using reed bed systems such as constructed wetlands may be appropriate. Modern systems include tertiary treatment by micro filtration or synthetic membranes. After membrane filtration, the treated wastewater is indistinguishable from waters of natural origin of drinking quality. Nitrates can be removed from wastewater by microbial denitrification, for which a small amount of methanol is typically added to provide the bacteria with a source of carbon. Ozone Wastewater Treatment is also growing in popularity, and requires the use of an ozone generator, which decontaminates the water as Ozone bubbles percolate through the tank. Disposal of wastewaters from an industrial plant is a difficult and costly problem. Most petroleum refineries, chemical and petrochemical plants have onsite facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the local and/or national regulations regarding disposal of wastewaters into community treatment plants or into rivers, lakes or oceans. Other Industrial processes that produce a lot of waste-waters such as paper and pulp production has created environmental concern leading to development of processes to recycle water use within plants before they have to be cleaned and disposed of.
