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...

Yes, "Odour" can also affect Law Enforcement!! Smell perception is not only odour sensation, it is also triggering of experiences and emotions associated with that smell. Research shows that many of our olfactory likes and dislikes are based purely on emotional associations. As, olfactory receptors are directly connected to the limbic system, which is thought to be the seat of emotion. Considering, smell as one of the strongest of the senses which influence brain activity, a bad or foul smell can also trigger bad influence or experience. Two years before, when I came to Ahmedabad, Gujarat, what I saw, in India, is considered as normal practice and negligible stuff. At Maninagar Railway Station, "Police Chowki" (Police Station) and "Peshab Ghar" (Open Urinal) are sharing common wall. It is obvious, one can sense pungent ammoniacal smell of the urine near to the open urinal. Considering, near by, well facilitated new toilet building, it doesn't...

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 C...

Consent to Establish (CTE), also known as No Objection Certificate (NOC), is a mandatory legislative requirement for every industry / local body discharging any domestic sewage or tra de effluent into water body or on land and / or caus ing emission of any air pollutant in Air Pollution Control Area (APCA). A ll polluting facilities are legally required to obtain a CTE from respective State Pollution Control Board (SPCB) . The CTE will be granted after an evaluation of the potential environmental impact and design of P ollution C ontrol Measure (PCM) . The conditions for PCM is part of CTE, which should be complied.
