Aqua Designs offers technology to handle the final concentrated effluent generated from any recycling system. The technology adopted is specific to the nature and quantity of effluent to be handled.
Forced Evaporation systems
This system operates based on a combination of the relative humidity present in the air and solar heat. The waste water to be treated is evaporated in a three stage process. The first stage involves spraying the water in the air by utilizing specially designed nozzles which produce a fine aerosol. This helps in maximum absorption of heat and increase the evaporation of water. The concentrate from this stage is taken to crystallization pans from where the crystallized salt is recovered.
Evaporators
Evaporators operate on a principle of utilizing the heat source to evaporate the concentrated waste. Evaporators can be adopted to utilize the following heat sources which would be available in various industries
Steam
Flue gas
Process gas / water with adequate temperature
If none of the above sources are available, the evaporator can be operated on a diesel based fuel or steam.
The type of evaporator recommended depends on the nature and the quantity of effluent to be treated. Typical evaporator options available are:
Mechanical evaporators which utilizes diesel / furnace oil as fuel.
Vacuum based multistage stage falling film type evaporators utilizing steam as the heating media.
Root Zone Treatment
In specific cases where dissolved solids are low and effluent needs to be disposed, Root zone base treatment offers solution, which involves cultivation of a specific grass based vegetation that is capable of high water and organic absorption.
