Eco-logical Water Quality Criteria for Zero Discharge

Copper Corrosion Method30

  • Immerse a copper wire in water sample for 24 hours. If copper shows no corrosion, water is practically clean for drinking.
  • If copper shows no corrosion in 24 hours, it keeps shining for
    days, weeks and months. Then the test needs no waiting time, we just have to see it shining each day.
  • It can be used to find purity of not only water, but also of cooking oil, milk, fruit juices and beverages.
  • It can be used to find purity of raw or treated sewage or industrial wastewaters. If copper shines, we can be sure there are no organic, inorganic or biotoxins in the sample.
  • If copper shines, treated sewage or industrial wastewater may still have nontoxic organic food that will be a resource for soil or fish.

High Total Dissolved Solids (TDS) is considered as an indicator of water pollution. But we do give high TDS (about 4,000mg/lt, these are minerals) coconut water even to sick people. W.H.O. norm that TDS shall be less than 500mg/lt for drinking and 2,100mg/lt for irrigation, should be modified. If copper test passes the water/wastewater sample, then it is not only safe, but a resource for the intended application, even if current limits are not met.

Hardness of water is an important parameter that controls its ability to cause scale in pipelines or urinary tract (kidney stones). But scale formation is actually due to nitrates (root cause) and calcium is just a battery for the alarm (scale). When we reduce calcium and declare the water to be soft, we are only preventing the alarm, but the problem (nitrates) is still there. Plus we remove calcium which is beneficial and replace it with sodium that is harmful for human body. Ecotechnological methods such as BioSanitizer Ecochips give us soft water that has calcium in place and need no softening column that needs regeneration using salt. If copper corrosion is not there, one can be sure that water is soft.

If RO is used to reduce TDS, we are also losing precious minerals that our body needs. After the RO treatment, water becomes more corrosive because small ions of hydrogen and nitrates pass %wise more through the membrane than the useful minerals. RO water is ion-hungry and can remove minerals from bones and other body tissues, causing severe health problems that we may not blame to water!

What about pathogens/pests?

Pathogens and pests have similar role in Nature. Pathogens are microscopic pests. They are firefighters of Nature. They come only when there is spillage (waste) of plant food (nitrates, heavy metals, etc.). Nitrates cause fermentation and this produces acidity. Acidity can dissolve rock particles and metals. Soluble heavy metals then create toxicity. Please see the ‘Niche Diagram of Pests’ showing how different levels of acidity and moisture invites specific pest action. Flies breed in alkaline pH that is produced when proteinous waste gets degraded in presence of nitrates and produce ammonia.

Pests detect the crisis (waste of nitrates, away from growing plants). They are biosensors or bio-indicators of Nature. They devour the acidic/ alkaline food and correct the pH. They are helping us remediate the crisis (pollution). They cause variable degree of nuisance to us, only to warn us about the crisis (waste of resources).

Pests thus can be tackled best by not inviting them, by preventing spillage of resources. If nitrates are not wasted and if they do not produce acidic or alkaline pH in presence of carbohydrates/ proteins, pests do not come. This is ecological sanitation, that is, sanitation without killing pathogens/pests.

If we try to kill pathogens/pests using toxic chemicals, they develop resistance over time (due to their faster breeding rates) and man develops cancer.

If we prevent the sanitary inspectors of nature, nitrates get built up in human society and we get ‘Mad Human Disease’ due to increase in greed, violence and other crimes in human society.

BioSanitizer Ecochip Technology

This is the latest ecotechnology that has been developed by Bhawalkar Ecological research Institute (BERI), Pune through 40 years of research, in collaboration with Nature that has 4.6 billion years of evolutionary experience.

100 mg of BioSanitizer Ecochips present us the bio-services of 1 acre of natural forest ecosystem. BioSanitizer is kept in a well, borewell or water bodies such as lakes, ponds and even in polluted streams and rivers and seas.

BioSanitizer Mechanism

BioSanitizer grows invisible plants and set up high-speed, broadband phyto-remediation that convert polluted water into water that is full of resources.

Water and wastewater treatment takes place without use of chemicals, machinery, electricity, trained manpower, in short, without any operating expenses. The sanitizer converts pollution (both organic or inorganic) into valuable resources, making it a sustainable operation.

BioSanitizer produces a water stream that is clean (devoid of toxicity). But its action also ensures that the stream resists recontamination. This feature helps us protect a community against future pollution events due to natural calamities, accidents or terrorism.


Eco-Logic has helped in developing simple methods of testing water, cooking oil, milk and beverages that are orally consumed. Same Eco-Logic has also given a simple, broadband, high-speed method, that of using BioSanitizer Ecochips, to clean water, other liquids and total ambiance.
