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
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.
