The present invention relates to a process for the clarification of brine in a chlor-alkali industry or any related process industry with the use of a submerged membrane. The process eliminates use of anthracite, pre-coat, micro and ultrafiltration pressurized systems in the existing brine treatment plant, is simp...

A method for the manufacture of ammonia free sodium carbonate or soda ash lye of concentration 50 - 380 gpl with 2000 - 6000 ppm (29) of sodium sulphite from caustic soda solution and carbondioxide from the flue gas coming from the caustic concentration plant burning hydrogen and furnace oil/LSHS as fuel and utiliza...

A PROCESS FOR THE RECOVERY OF SODIUM SULPHATE FROM THE BRINE RESULTING FROM NANOFILTRATION MEMBRANE SYSTEM IN CHLORALKALI PRCESS The present invention relates to a process for the recovery of sodium sulphate from the brine resulting from Nanofiltration system in chloralkali process by utilizing the decreasing solubili...

The present invention relates to a cost-effective and autonomous system for detecting, mitigating and containment of leaked chlorine gas from the any manufacturing or utility facility. The provisions are made to effectively contain the leaked gas as soon as the leakage exceeds a predetermined threshold. Further, the...

The present disclosure relates to an eco-friendly process of manufacturing bricks, blocks or paver blocks from brine sludge that is released as a waste in membrane chloralkali industry. Primarily, the brine sludge is used along with cement, aggregates, manufactured-sand or fly ash to obtain final brick blocks of gre...

The present disclosure is directed to an easily operable and cost effective system and process for reducing iodide concentration from the untreated brine to the levels as low as <100ppb. The efficient mixing of ozone with untreated brine in a fluidized bed reactor (F1) provides for an effective contact surface f...

ABSTRACT The present invention relates to a highly effective system for cleaning the biological and inorganic fouling in the intake pipe (6) and the intake head of a seawater desalination plant. A systematic cleaning process for the intake pipe (6) and intake head (5) is illustrated that includes disinfection step ...
