Media, Local Politics, Greedy Industrialist should awake and save the country which is Heart for living. Polluting rivers means Killing Generations to come not saving any thing for your own children. CLOSE industries if no SOLUTION is provided. if they close only few people will be hurt. but allowing them makes lacks of people (already) effected. There will be no food in front of our own table. People mind set should be changed.
I request gov to give some other Temp Job facilities if closed

A trickling filter consists of a bed of rocks, gravel, slag, peat moss, or plastic media over which wastewater flows downward and contacts a layer (or film) of microbial slime covering the bed media. A bed of filter medium upon which a layer of microbial slime is promoted and developed.
An enclosure or a container which houses the bed of filter medium.
A system for distributing the flow of wastewater over the filter media

Hydrocyclone Oil Separators Hydrocyclone oil separators operate on the process where wastewater enters the cyclone chamber and is spun under extreme centrifugal forces up to 1000 times the force of gravity. This force causes the water and oil droplets to separate. The separated oil is discharged from one end of the cyclone where treated water is discharged through the opposite end for further treatment, filtration or discharge.

Activated sludge is a biochemical process for treating sewage and industrial wastewater that uses air (or oxygen) and microorganisms to biologically oxidize organic pollutants, producing a waste sludge (or floc) containing the oxidized material. In general, an activated sludge process includes:

An aeration tank where air (or oxygen) is injected and thoroughly mixed into the wastewater.
A settling tank (usually referred to as a clarifier or "settler") to allow the waste sludge to settle.

Evaporation processes are the most widespread for brine treatment as they enable the highest degree of concentration, as high as solid salt. They also produce the highest purity effluent, even distillate-quality. Evaporation processes are also more tolerant of organics, hydrocarbons, or hardness salts. However, energy consumption is high and corrosion may be an issue as the prime mover is concentrated salt water. As a result, evaporation systems typically employ titanium or stainless materials.

Brine treatment technologies may include: membrane filtration processes, such as reverse osmosis; ion exchange processes such as electrodialysis or weak acid cation exchange; or evaporation processes, such as brine concentrators and crystallizers employing mechanical vapour recompression and steam.

or maximize the recovery of fresh water or salts. Brine treatment systems may also be optimized to reduce electricity consumption, chemical usage, or physical footprint.

Brine treatment is commonly encountered when treating cooling tower blowdown, produced water from steam assisted gravity drainage (SAGD), produced water from natural gas extraction such as coal seam gas, frac flowback water, acid mine or acid rock drainage, reverse osmosis reject, chlor-alkali wastewater.

Brine treatment involves removing dissolved salt ions from the waste stream. Although similarities to seawater or brackish water desalination exist, industrial brine treatment may contain unique combinations of dissolved ions, such as hardness ions or other metals, necessitating specific processes and equipment.

Brine treatment systems are typically optimized to either reduce the volume of the final discharge for more economic disposal (as disposal costs are often based on volume)

GANGA, the name evokes a very different and pious feeling among the Indians, I feel a strong MEDIA campaign should follow before every NEWS BULLETIN, SPORTING EVENTS, SERIALS, BILLBOARDS, SOCIAL MEDIA, INVOLVE THE HOTELS where people stay across India of this initiative, RAILWAY,…the outcome would be, to instil a sense of guilt and fear that polluting river ganga in whatever manner, is a sin. Invoke, Ma Ganga in high decibels and you will see the result as we are all god fearing,

Tougher norms should come with effective monitoring & implementation. I feel the current day laws are strict enough to make the river clean; what is lacking is its on ground implementation. for example we have Municipal Waste Handling Rules but is anybody following them? Tougher norms can be implemented once the existing once are met, otherwise the stricter laws would be met with high resistance and would meet the same fate as those of existing laws.
