Introduction The extraction of alumina from bauxite by the Bayer process produces a slurry by-product referred to as ‘bauxite residue’ or ‘red mud’. The liquid component of the slurry is highly alkaline and requires neutralisation to render it environmentally benign. A common practice is neutralisation using Mg rich seawater, which results in the formation of the layered double hydroxide (LDH) ...

The present work aims to assess the water quality index (WQI) of Manyad Storage tank, Aurangabad district, Maharashtra, India. surface sample were assessed for physico-chemical parameters namely pH, Electrical Conductivity, Total Dissolved Solid, Hardness, Bicarbonate, Chlorides, Sulphates, Nitrates, Calcium, Magnesium, Sodium, Potassium and Fluoride in post-monsoon season 2020. For calculating...

Agrotechnical assessment of struvite produced by a lab-scale sedimentation unit is performed. As source phosphates and ammonia, liquor obtained through dewatering ?unicipal wastewater treatment plant sludge was in use. The range ammonia the 130 - 250 380 560 mg/L, respectively. Seawater brine with magnesium concentration around 60 g Mg2+/L applied as magnesium. agrotechnical characteristics wer...

A flow injection system for the simultaneous determination of uranium and thorium has been developed by using selective masking and a spectrophotometric detector with two flow cells aligned with the same optical path. The injected sample solution was first mixed with a reagent solution containing Chromazurol S (CAS) and cetyltrimethylammonium chloride (CTMAC), and the total absorbance of uraniu...

Groundwater quality and quantity both are important for the survival of human beings on this planet. In present study an attempt has been made to assess groundwater at mass using points. To fulfil objectives study, four sites (Sahibabad, Ghaziabad, Muradnagar, Modinagar) were selected along metro line construction from Delhi Meerut. At all these sites, workers projects living working drinking p...
