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 S

There is a need of effective Air Pollution Control Measures (APCM) adaptation by Small and Medium-sized Enterprises (SMEs). This year, Gujarat Pollution Control Board (GPCB), Gandhinagar had conducted Seminar on Odor Control, emphasizing on the consideration of human sensation, i.e. visual and odor, for planing good and effective APCM. Central Pollution Control Board (CPCB) had also proposed to Install online Continuous Stack Emission Monitoring Systems (CSEMS) in identified highly polluting industries. However, in the evening, between 18:00 to 19:00 Hours, while crossing Dr. Ambedkar Bridge, one can observe Black Smoke Emission from stacks of the SMEs located at Danilimda, Ahmedabad. Also, one can sense foul odor near Danilimda BRTS Stop, which may be due to Pirana Sewage Treatment Plant (STP), which is one of the biggest STP in Asia. The idea, behind writing this article, is to strictly implement Air Pollution Control Systems (APCS) i.e. Bag Filters, Cyclone Separators,
