I. INTRODUCTION

There are two years left for presidency focus of

guaranteeing all Indians utilize toilets, yet in urban India

alone, only 30% sewage is generated by numerous

individuals which pours in treatment plant. The remainder is

arbitrarily left in waterways, oceans, lakes and wells,

dirtying 3/4th of the nation's water bodies, as indicated by

different information sources. An expected 62,000 million

liters for each day (MLD) sewage is produced in

metropolitan zones, while the treatment limit crosswise over

India is simply 23,277 MLD, or 37% of sewage created, as

per information discharged by the administration in

December 2015. Additionally describing of this information

uncovers that of 816 metropolitan sewage treatment plants

(STPs) recorded crosswise over India, 522 work. During

this way, of 62,000 MLD, the recorded limit is 23,277 MLD

however near 18,883 MLD of sewage is de facto treated. It

means that 70% of sewage created in urban India isn't

treated well while 79 STPs don't work, 145 are under

development and 70 are proposed, as indicated by the

Central Pollution Control Board's (CPCB) Inventorization

Of Sewage Treatment Plants report.

India is a one of the populated nation and this is the main

purpose behind huge waste being created frequently out of

family and modern exercises like peeling and cutting of

crude natural product squanders and vegetables squander

utilized for preparing, eating and cooking. On the off

chance that these natural waste or refuse when transparently

dumped in open spots causes contamination or make hurtful

consequences for soil, water, air and groundwater. Indeed,

even today, huge part of solid waste is dumped on edges of

towns or urban communities with no earlier treatment this

prompts groundwater tainting and increment in air

contamination and increment in air contamination due to

leachate permeation and increment in gases individually.

Different examination uncovers that out of aggregate strong

waste 80% can be used again either by reusing or reusing.

For the most part in Indian urban areas the formal preparing

and recuperation of units are not built up and the money

related ramifications of recuperation and reusing has not

been examined or considered to utilize strong waste for

fund age. Enzymes have assumed a critical part in numerous

parts of life since the beginning of time. Indeed they are

fundamentally essential to the presence of life itself. Human

advancements have utilized catalysts for a great many years

without understanding what they were or how they function.

In the course of the last a few ages, science has opened the

riddle of compounds and has connected this learning to

improve utilization of these astonishing substances in a

consistently developing number of uses. Enzymes assume

important parts in creating the nourishment we eat, the

garments we wear, even in delivering fuel for our vehicles.

Eco-enzyme is only vinegar or liquor got from maturing

new kitchen waste, for example, veggie and organic product

leftovers (peels, cuttings and bits), sugar (dark colored

sugar, jiggery or molasses sugar) and water. The chemical is

inferred after one channels and evacuates the buildup

following 3 months. The key fixing is molasses, which the

microscopic organisms and microorganisms introduce in the

waste process into liquor. This is diminished in its last

frame to acidic corrosive or vinegar. Vinegar with its acidic

properties is notable as an inside and out non-harmful more

clean.

II. MATERIALS AND METHODS

A. Collection and Preparation of Samples –

Fruits wastes such as Water melon, Orange, Nose berry and

Pomegranates, and vegetable waste will collect from

individual household for the preparation of Eco enzyme.

And Domestic waste water sample is use for testing the

efficiency of eco enzyme.

B. Testing of Eco enzyme sample –

The characteristics of filtered Eco enzyme sample were

analyzed after 15 days of filtration. A parameter such as pH,

protein, carbohydrates, TDS, BOD, COD and MPN were

analyzed as per procedure in ordinary methods.

C. Testing of Eco enzyme sample

In the study, 5% and 10% of Eco enzyme of domestic waste

water were selected. Four beakers were filled by the

particular dilutions of eco enzyme selected solution. These

beakers were concealed with aluminum foil and were left

for process of digestion. The parameters like pH, TDS,

BOD5, COD, and MPN were analyzed for all the selected

samples as per procedures in ordinary methods.

III. EXPERIMENTAL SETUP

A. Preparation of Eco-Enzyme

For the preparation of Eco-enzyme we required three main

materials that are easily obtained and cheap. The most

material of the preparation was the food wastes like peeled

fruit skin and vegetable waste, water and jiggery in keeping

with research, forty-five percent of household waste is

organic waste like fruit peels. Thus, this proved that the

most material of the rubbish enzyme preparation was easily

obtained daily. This scraps is then fermented in a bottle of 5

liter capacity for 3 months together with jiggery and water

in ratio of 3:1:10(w/w). As an example, to arrange 1 liters of

garbage enzyme: 300gm of food wastes, 100 gm. of brown

sugars and 1 liters of water are required. The container used

is totally air-tight; ensure the container cap is released a

minimum of once on a daily basis day for a primary few

weeks to let loose built-up gas of fermentation so as to

avoid any explosion because of air mass exertion from the

fermentation gas released.

After the three months completion of fermentation process

filter the mixed sample and remove residue left over.

III. RESULT DISCUSSION

The characteristics of filtered Eco enzyme sample were

analyzed after 15 days of filtration. The parameter like pH,

TDS, BOD, COD and MPN were analyzed as per procedure

in ordinary methods. Within the study, 5% and 10% of Eco

enzyme with domestic waste water was selected. Two

beakers were filled by the particular dilutions of eco

enzyme solution. These beakers were concealed with

aluminum foil and were left for digestion. The parameters

like pH, TDS, BOD5, COD, and MPN were analyzed for all

the samples as per ordinary method.

treated with 5% eco enzyme solution showed percentage

reduction for TDS is 12.32%. It removes BOD 62.51 % and

reduction in COD is found 44.76%. It can remove total

coliform bacteria near to 90%.

The pH values were improved from 4.16 to 6.82 after 5

days of digestion timeline. The domestic waste water when

treated with 10% eco enzyme solution showed percentage

reduction for TDS is 13.94%. It removes BOD 65.40 % and

reduction in COD is found 48.66%. It can remove total

coliform bacteria near to 99.9%.

IV. CONCLUSION

The percentage reduction of varied parameters of enzyme

solution was higher after 15 days of filtration. The enzyme

activity of Eco enzyme was enhanced with time. The

digestion days may be reduced by increasing the time of

fermentation period. The effluent characteristics met the

irrigation standards after 5 days. The treatment of domestic

waste water using enzymes is economical only when the

time of digestion is a smaller amount. Further studies are

required to scale back the digestion days in order that

enzymes may be used effectively Eco enzyme may be a

product produced with the use of stuff like fruits peeled and

vegetable waste, jiggery or sugar and water with the recipe

and methods published in media. Production of Eco enzyme

is double advantageous that it can reduce load on organic

solid waste management and even have the various

applications in agriculture, livestock farming, domestic

cleaning etc. However, before full potential of Eco enzyme

may be known. Some major issues remain to be addressed

like characterization of Eco enzyme, Assessment of their

impact on the environment, identification of methods of

disposal of solid residue left after the filtration of sample.

Jun 2023

With rapid industrialization and ongoing development activities by humankind has polluted the water and reduced the quality of water at such a level that it becomes a threat to life. Since, water is an essential element for nature as well as for humans to perform various tasks to run the continuous cycle of survival. It becomes very much essential to make it pure. In past few years, researchers are working to find new techniques for reclamation of water focusing on biological or physical wastewater treatment methods rather than chemical ones. Use of bio-enzyme in biological treatment of wastewater could be a viable and eco-friendly solution. In this study bio-enzyme obtained from fermentation of flower waste was used to treat the wastewater (greywater) sample. The wastewater samples were digested for a period of 5, 15 and 25 days by mixing with 5%, 10% and 15% bio-enzyme solution. The parameters like pH, TDS, BOD5, COD, Ammonia Nitrogen and Phosphates were analyzed for present investigation. The results showed that bio-enzyme can remove TDS, BOD5 and COD characteristics of the wastewater; while complete removal of ammonical nitrogen and phosphate was observed with low concentration of bio-enzyme solution. No considerable variation in the characteristics pH was noted; it remains acidic. Bio-Enzyme can be used as an economic option to enhance wastewater attributes by treating it with bio-enzymes and make fit it for various purposes. Moreover, utilization of bio-enzymes can also help in checking disposal of chemicals during wastewater treatment processes making it environmentally sustainable.

Applying Eco Enzyme to Reduce Chemical Oxygen Demand (COD) Content of Artificial River Water

Article

Mar 2023

Eco enzyme is claimed to improve the quality of polluted water. However, the low pH of eco enzyme solutions can acidify water. The objective of this study was to investigate the effectiveness of eco enzyme in reducing the COD of river water and its effect on the pH of sterilized synthetic river water. The effect of 0.01%, 0.5%, and 1% enzyme concentrations on the COD and pH of synthetic river water with an initial COD of 240 mg/l was investigated. The results showed that eco enzyme itself has high concentration of COD and low pH. The undiluted eco enzyme increased the COD and decreased the pH of both neutralized and non-neutralized synthetic river water. At a 1% eco enzyme concentration and neutral pH, the COD increased in the beginning of experiment and had decreased only by 31.7% after 6-8 days. The COD concentration in this steady state condition had a higher value than that of the initial COD concentration in the river water. This study showed that adding only eco enzyme to synthetic river water is not effective in reducing its COD content.

The Effect of Eco-Enzyme Spraying on Suwung Landfill Waste, Denpasar, on Changes in Leachate Characteristics

Article

Full-text available

Jan 2023

Introduction: Bali, as an international tourist destination, is still experiencing problems in waste management. Suwung Landfill, Denpasar, is one of the landfills for waste originating from the Denpasar, Badung, Gianyar, and Tabanan (Sarbagita) areas. Methods: This research was an experimental study, by watering eco-enzymes on garbage heaps and examining changes in leachate parameters. Watering was carried out daily at a dose of 1 L of eco-enzyme dissolved in 1000 L of water and used for watering a garbage pile of 1 ha. The area of piles of garbage watered with eco-enzymes reaches 5 ha. Measured leachate parameters include pH, BOD, COD, TSS, N, cadmium, and mercury. Results and Discussion: Eco-enzymes have the potential to become activators or decomposers in waste composting. The evidence is that eco-enzyme watering causes the average leachate temperature to range from 36.63 to 40.370C, where the increase in leachate temperature occurs due to the rise in the temperature of the garbage pile. An increase in temperature characterizes the activity of microbes increases, so the decomposition process becomes rapid. Conclusion: Eco-enzyme spraying leads to a characteristic change in the form of an increase in the value of leachate parameters. The increase in temperature value, pH, BOD, COD, and N content of leachate indicates that environmentally friendly enzymes accelerate the decomposition of organic matter. The rapid decomposition process causes the total suspended density of leachate to increase.

A REVIEW ON UTILITY OF ECO-ENZYME AND ITS EFFECTIVENESS IN TREATMENT OF DOMESTIC WASTEWATER

Article

Full-text available

Apr 2021

Wastewater treatment is a huge concern globally as water is one of the most vital resources for survival. Despite being present in abundance, the amount of water available for drinking purposes is much lesser. All life forms depend on water for their survival; thus, it is important that the water quality be maintained. Increasing population, industrialisation, and urbanisation is causing the water pollution level to go up and the treatment methods and facilities are not sufficient or efficient enough to cope up with it. On the other hand, solid waste management is a huge concern given the harmful effects disposal of solid fruit and vegetable waste is having on the environment and health. Eco-enzyme is emerging as a solution that can help on both the accounts simultaneously along with its multiple utilities like household cleaning, laundry, fertilizer, pesticide, dishwashing, deodorizer, and many more. It is prepared by fermentation of fruit or vegetable or flower waste along with water and jaggery. Eco-enzyme has been suggested to be a viable solution to treat domestic wastewater in many studies and also reduces the environmental footprint of solid waste. The present review focuses on the utility of eco-enzyme and its effectiveness on domestic wastewater treatment.

Treatment of Domestic Waste Water Using Organic Bio-Enzymes Extracted from Seasonal Citrus Fruits

Article

Aug 2022

Humankind has significantly degraded the quality of the world's water supplies as a result of massive industrialization in emerging nations like India. Due to these high levels of pollution, not just humans but all other life forms are now at jeopardy from the water's quality. Several measures have been taken to preserve the ongoing cycle of survival as water is a necessity for all life forms to flourish. Researchers have been working on new methods for water reclamation for a several years already, focusing on biological or physical wastewater treatment rather than chemical treatment, which degrades the quality of groundwater and damages the ecosystem. The wastewater is digested for 3, 5, and 8 days by mixing it with (1:1000) bio enzyme solution. COD (chemical oxygen demand), BOD (biological oxygen demand), alkalinity, pH, nitrate-nitrogen, nitrite nitrogen, ammoniacal nitrogen, phosphorus, and e. coli were measured. Organic biocides were found to be capable of removing COD, BOD, ammoniacal nitrogen, nitrate nitrogen, and nitrite nitrogen from samples while lowering the phosphorus content to acceptable levels specified by Indian Standard Codes. There were no significant differences in the pH characteristics observed. Organic biocides can be used as a cost-effective option for wastewater treatment in both urban and rural areas to improve water quality and make it suitable for various agricultural uses.

Enzyme technology and biological remediation

Article

Feb 2006
ENZYME MICROB TECH

The heterogeneous complexity of sludges and wastewaters has created gross uncertainty and deviations in predictions of suitable models for their measurement. At the same time, it is becoming increasingly obvious that the current paradigms and ideologies are wrought with problems and limitations suggesting the need to move to a more consolidated analytical objective evaluation. Rapid developments in understanding activated sludge processes and wastewater remediation warrants exploitation of different strategies for studying their degradation. It is time to replace subjective terms like sludge volume index (SVI), zone settling velocity (ZSV), filament index (F I), fractal dimension (D), flocculating ability, surface charge (ζ), degree of hydrophobicity, chemical oxygen demand (COD) with a mathematical one that can provide an absolute quantitative relationship for the properties of wastewater and/or a sludge floc. There are no current objective values that can be introduced to represent the plethora of biological remediation terminologies such as bioleaching, biosorption, bioaugmentation, biostimulation, biopulping, biodeterioration, biobleaching, bioaccumulation, biotransformation and bioattenuation. Enzyme technology has been receiving increased attention and this review focuses on the latest developments on the enzymology of biological remediation. It discusses the present pitfalls with current strategies and suggests that sludge–floc parameters, such as internal structure and composition, sludge retention time, microbial ecology, nutrient concentration, dissolved oxygen and type of industrial wastewater, whether from an aerobic or anaerobic system, are replaced by quantitative kinetic terms (K m , V max , K cat) associated with the enzymology of the sludge floc and/or wastewater.
