30/6/2014, · The ,acidic, process water is stored in open impoundments that attract migratory birds. Birds landing in these ,acidic, ponds can ingest this water which causes severe trauma to their gastrointestinal tracts and eventual death. The ,acidic, water also removes natural oils from the birds’ feathers causing them to die by drowning or hypothermia.

Ferric sulfate | Fe2(SO4)3 - PubChem

Method 4500-Sulfate ion F. Automated Methylthymol Blue Method for the determination of sulfate ions in water and ,wastewater,. Barium sulfate is formed by the reaction of the sulfate ion with barium chloride at a low pH. At high pH, excess barium reacts with methylthymol blue to produce a blue chelate. The uncomplexed methylthymol blue is gray.

Ca removal and Mg recovery from flue gas desulfurization ...

Selective removal of Ca and recovery of Mg by precipitation from ,flue gas desulfurization (FGD) wastewater, has been investigated. Thermodynamic analysis of four possible additives, Na 2 CO 3, Na 2 C 2 O 4, NaF and Na 2 SO 4, indicated that both carbonate and oxalate could potentially provide effective separation of Ca via precipitation from Mg in FGD ,wastewater,.

bide ,desulfurization, slag prevents the pH from dropping to a point where hy-drogen sulfide gas is formed. However, the treatment water contains bisulfide, and therefore has the potential for re-leasing H^S if the ,wastewater, is neu-tralized in a settling pond or ,wastewa-ter, treatment plant before the sulfide has been adequately diluted.

What Is Zero Liquid Discharge (ZLD)? | Fluence

20/12/2019, · Mining is another industry that benefits from a ZLD approach to ,wastewater, treatment. Raw mining ,wastewater, is ,acidic, and extremely saline, and often contains a large amount of sediment. A good example is the Collahuasi Copper Mine, a project undertaken by RWL Water before it merged with New York-based Emefcy to form Fluence in 2017.
