Multi effect evaporator (MEE)
A multi-effect evaporator is a type of industrial evaporator used to evaporate liquids, typically in the food, chemical, or pharmaceutical industries. It is called a “multi-effect” evaporator because it uses multiple stages, or “effects,” to evaporate the liquid.
MEE is the most efficient and successful conventional evaporation method to achieve a complete zero-liquid discharge for any type of industrial effluent.
The basic principle of a multi-effect evaporator is that the vapor produced in one effect is used as the heating source for the next effect, which helps to reduce energy consumption. The evaporator consists of a series of vessels or stages, each of which is maintained at a lower pressure than the preceding one. As the liquid enters the first stage, it is heated and partially evaporated. The vapor produced in the first stage is then used to heat the liquid in the second stage, and so on, until the liquid is fully evaporated.
We provide the best and sustainable solution to our clients in recovery and achieving Zero liquid Discharge for their facility.
Application of MEE Plants in industries are generally Zero Liquid Discharge, Wastewater treatment, Salt recovery, Product concentration and having many advantages like maximization of steam economy, reduce energy requirement to run Zero Liquid Discharge system, Provision of High Heat Transfer area and sustainable & successful Conventional method for ZLD
Agitated thin film dryer (ATFD)
The ATFD operates on the principle of creating a thin film of the material to be dried on a heated surface, while agitating the film to promote faster and more even drying. The dryer consists of a cylindrical vessel, usually made of stainless steel, which is heated using a hot oil or steam jacket. Inside the vessel, there is a rotor with agitator blades that scrape the film off the heated surface and circulate it in the vessel.
The advantages of ATFD include its high efficiency, low operating costs, and gentle handling of heat-sensitive materials. The agitating action of the rotor helps to reduce the drying time and minimize the risk of overheating or burning of the material. The thin film created by the ATFD also helps to increase the surface area for heat transfer, which further enhances the efficiency of the drying process.
Effluent Water Treatment Plant
Effluent water treatment plants are essential for protecting the environment and public health, by preventing the discharge of harmful pollutants into natural water bodies and ensuring the safety of our water resources.
An effluent water treatment plant is a facility designed to treat industrial wastewater or effluent that is produced by process, floor washing or any other methods, in order to remove pollutants and contaminants from the water and make it safe to release back into the environment.
The treatment process typically involves several stages, which may include physical, chemical, and biological processes. The primary goal of the treatment process is to remove contaminants such as suspended solids, organic matter, nutrients, pathogens, and other harmful substances from the effluent.
Some common processes used in effluent water treatment plants include:
- Screening and grit removal: In this stage, large objects such as sticks, rags, and plastics are removed from the effluent, and grit and sand are separated out.
- Primary treatment: The effluent is allowed to settle in a sedimentation tank, where suspended solids and organic matter settle to the bottom and are removed as sludge.
- Secondary treatment: This stage involves biological treatment, where microorganisms are used to break down organic matter in the effluent. The most common process used in secondary treatment is activated sludge treatment, where air is pumped into the effluent to promote the growth of bacteria that break down organic matter.
- Tertiary treatment: This stage is used to remove any remaining contaminants from the effluent. Processes used in tertiary treatment may include filtration, disinfection, and chemical treatment.
After the treatment process is complete, the treated effluent is typically discharged into a water body, such as a river or lake, or used for non-potable purposes such as irrigation or industrial cooling.
