Salt recovery
With forced Recirculation Evaporator, the concentration can be done as long as the mixture of crystals and liquid is pumpable. The salts are then crystallised by cooling and remaining free water is returned to the evaporator feed system.
A two-effect Forced Recirculation Evaporator system has been installed at Orchid Chemical Pharmaceutical
Ltd in India. Orchid Chemicals is a pharmaceutical company producing base drugs for global market. The plant is located on reclaimed land and is using the two-effect evaporator together with existing Ultra Filtration and Reversed Osmosis membrane plants, to handle all waste water and recycle the clean water. Concen-trated organic waste water is being incinerated and the flue gases scrubbed with water. The scrubber water
is again evaporated and the remaining salts crystallised. The salts are sold. This plant is helping Orchid Chemicals in keeping their position as leading eco-friendly company, confirmed several times by achieving awards as India's most eco-friendly and fastest growing pharma company.
