THE PROCESS ADVANTAGES
Effluent handling is always very challenging. It contains hazardous chemicals and various salts and presence and percentage of these is very uncertain. ZLD from SAKA is most suited for these type of inputs. Many times these Effluents are so concentrated and strong that metal is not able to withstand it. For such processes we provide exotic lining material such as ceramic which can withstand the reactive effluents.
SAKA has total control over the energy efficiency. Highest amount of energy is lost from spray exhaust, we have ensured that our system pulls such gases before taking them to the ZLD. Pre-heating of Liquid Effluent also adds to energy saving. Many time effluent contains low boiler solvents, which are used in heat recovery process. These low boiler solvents are mixed in exhaust gas causing them to boil and evaporate. These evaporated gases are exhausted in the heater there by further reducing the heat requirements.
Few effluent require incineration process, While many ZLD’s include separate Incinerator even when it is not required. Our ZLD takes such chemicals to the spray dryer to remove the liquid from such feeds thus making them solid it is very easy and cheap to incinerate these material. Only incases of special and very critical applications a separate incinerator is used.
Advanced Incineration with Torrefaction
SAKA has one of the highly advanced incinerator. Where instead of burning the effluent, they under go torrefaction process where temperature of the material is increased without using oxygen and many elements like carbon, sodium sulfate etc are recovered from the effluent. These recovered element can be used for processing and have a salable value in the process industry.
Pollution Control Norms
With SAKA highly advanced ZLD, we have able to keep this emission well within pollution control norms. For norms like SOX, NOX where acceptable limit is 100 units we have been successful to keep it as low as 2.5 units.
