True Zero Liquid Discharge

Zero Liquid Discharge (ZLD), a process which is meant to be beneficial to effluent generating organizations, by saving money, as well as "Environment", as nearly all the generated waste have been reused back.

ZLD can be achieved by following means,

1) Thermal Operations

2) Filtration Operations

3) Combinations of Both


The main constraint of above-mentioned means are, the both technologies require high CAPEX as well as OPEX.

Consequently, water treatment experts were seeking for new innovative means, by which they can achieve ZLD, in most Economical Way.

The process, which makes me write this article, one of the most adopted ZLD System, for Reverse Osmosis (RO) Plant Reject, is Spaying Reject into the Atmosphere.

The said system looks like this


Coming to the point, which your "So-called Water Treatment Experts" didn't tell you, is ZLD simply means, "ZERO LIQUID DISCHARGE". Spraying high Total Dissolved Solids (TDS) RO Reject into the Atmosphere, is not ZLD.

Even, TDS limit of 2,100 mg/l, allowed by Government Bodies for Gardening, can emit about 500 mg/m3 of Mixed Pollutants into the Atmosphere.

Now, think what Environmental Impact will your system have when one spray High TDS RO Reject Water having TDS Value of 15,000 mg/l (Not Economical for Evaporation) and quantity of 1,000 Liters/Hour.

The said system will emit about 5,000 mg/m3.sec of the Mixed Pollutants into the Atmosphere.

Moreover, nearly same emission rates can be observed, in Open Pan Evaporators (OPE), having evaporation capacity of 1,000 Liters/Hour.

Due to Alkaline Nature and Micro Size (< 0.4 micrometer) of the Mixed Pollutants lead to Dermal as well as Respiratory System Damages.

This simply means, all the investment done by you to conserve the Environment is gone Waste.

The solution is very simple, to go for Common ZLD Systems, comprised of nearly 100% Resource Recovery Systems.

This will Reduce the CAPEX as well as OPEX, per unit, and enable the effective utilization of funds for the betterment of the Environment.

So called Sustainable Policies Leading to Catastrophe

Sustainable Development is a very complex idea, which makes it is very difficult to understand, even to the Policymakers.   “Sustainable Development is the development which meets the needs of the present without compromising the ability of future generations to meet their own needs.” - Brundtland Commission Ministries of the Government of India have come up with various schemes from time to time. Not getting into any political debate, if one look closely the policy making has been boomed from 2015.  However, it seems like policymakers have misinterpreted the sustainable development terminology and/or the pressure of making more number of policies had requisite them to make contradictory policies, which shall lead to catastrophe. For example, consider the case of "Water Resource in India". India represents 16% of the World Population, accounts for 2.45% of Land Area and Only 4% of Water Resources of the World. The government had alrea...

Heliosphere and Cosmic Microwave Background Radiation

Heliosphere and Cosmic Microwave Background Radiation During the discussion on how to harness the  #energy  radiated by the  #sun , to become a type 2  #civilization  characterized by Kardashev, the question arises we are not even close to type 1 civilization, and we are thinking of type 2 and 3. On further discussion, we identified the heliosphere, the protective magnetic bubble generated due to charged particles (electrons and ions or plasma) streaming away from the Sun, which can be a possible explanation of  #cosmic   #microwave   #background  ( #cmb )  #radiation . Considering the heliosphere distance of 100 AU (Astronomical Unit) from the Sun, our  #earth  is approximately at the center of the heliosphere with a distance variation of about 0.01 times the 100 AU. Bingo! If this is true, can microwave photons having an energy of about one micro electron volts (eV) to 0.001 electron volts readily be scattered by the heliosph...
