Zero Liquid Discharge - an overview | ScienceDirect Topics

Mar 01, 2020 · Zero liquid discharge (ZLD) is a strategic wastewater management system that ensures that there will be no discharge of industrial wastewater into the environment. It is achieved by treating wastewater through recycling and then recovery and reuse for industrial purpose. Hence ZLD is a cycle of closed loop with no discharge.

Flue Gas - an overview | ScienceDirect Topics

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.

Total Dissolved Solid - an overview | ScienceDirect Topics

Water softened by the above process would contain more sodium bicarbonate in boiler water, and produce caustic soda which is highly corrosive in nature. Another modification of the process 'hot-lime zeolite softening process' ( Fig. 11.12 ) is used to increase silica reduction and carried out at 98°C.

Boiler water treatment - Lenntech

This involves pretreatment of the water with lime to reduce hardness, alkalinity and in some cases silica, and subsequent treatment with a cation exchange softener. This system of treatment accomplishes several functions: softening, alkalinity and silica reduction, some oxygen reduction, and removal of suspended matter and turbidity.

Edetic acid | C10H16N2O8 - PubChem

Edetic Acid is the acid form of edetate, a chelating agent with anti-hypercalcemic and anticoagulant properties. Edetic acid binds calcium and heavy metal ions, forming soluble stable complexes which are readily excreted by the kidneys. This results in a decrease in serum calcium levels. This agent is also used as an anticoagulant for blood specimens and is applied as a treatment of lead

The Cost of Desalination - Advisian

The cost to desalinate industrial wastewater for reuse can be much greater than this. For example, WorleyParsons/Advisian conducted a study to develop the CAPEX and OPEX for a 35,000 m3/day desalination plant located in the Arabian Gulf region and being fed with oil field produced water and producing boiler feed water.

hard water | Definition, Examples, & Facts | Britannica

Hard water, water that contains salts of calcium and magnesium principally as bicarbonates, chlorides, and sulfates. Ferrous iron may also be present; oxidized to the ferric form, it appears as a reddish brown stain on washed fabrics and enameled surfaces. Water hardness that is caused by calcium bicarbonate is known as temporary, because boiling converts the bicarbonate to the insoluble
