Zero Liquid Discharge (ZLD) is an advanced water treatment process that aims to reuse water in production without any waste discharge. It has minimal environmental impact and reduces operating costs. The ZLD process involves pre-treatment, concentration, and thermal treatment. Pre-treatment reduces suspended solids, chemical oxygen demand, and turbidity. Concentration of dissolved solids is achieved through membrane technologies like reverse osmosis (RO) or electro dialysis (ED). Thermal treatment includes evaporators and crystallizers, producing crystalline salts. The benefits of ZLD include minimizing wastewater discharge, addressing environmental concerns, reducing reliance on local water sources, and meeting legislative standards. ZLD is an effective strategy for wastewater management and extends water supply while reducing pollution.
Multiple Effect Evaporator (MEE) is a widely used system in various industries for evaporation and achieving desired concentration levels. It consists of a sequence of heat exchangers, known as VLSs (vapor-liquid separators), which utilize a sufficient amount of heat from sources like steam or hot water to evaporate water. The evaporation process is carefully controlled to prevent solute precipitation. Industrial evaporators typically feature tubular heating surfaces, which can be horizontal or vertical, long or short. The liquid being processed may either be inside or outside the tubes. MEE enables efficient evaporation and concentration while ensuring optimal performance in industrial applications.
Free Falling Film Evaporator (FFFE) is a feeding method commonly used in multi-effect evaporators. In this method, the feed and steam are introduced together in the first effect, and the feed passes from one effect to another in parallel with the vapor from the previous effect. By feeding steam, a small amount of water vapor is formed, which heats the second effect. The vapor releases its latent heat and condenses, resulting in a smaller amount of vapor in the second effect. This process continues in subsequent effects until the vapor temperature approaches the feed seawater temperature. FFFE facilitates efficient heat transfer and vapor generation in the multi-effect evaporator system.
Forced Circulating Evaporators (FCE) are commonly employed for liquids prone to fouling, scaling, crystallization, or those with inverse solubility, as well as when concentrating thermally degradable materials. The high recirculation rate in FCE enables rapid liquid velocities through the tubes, minimizing the accumulation of deposits or crystals on the heating surface. This type of evaporator is versatile and particularly suitable for concentrating solutions containing encrusting substances, hardening agents, undissolved solids, and viscose solutions. It is also well-suited for evaporative crystallization processes. FCE plays a crucial role in preventing fouling and achieving efficient concentration in challenging liquid applications.
Agitated thin film evaporators are ideal for handling fluids with high sensitivity and viscosity. They consist of a jacketed shell and a high-speed rotating rotor. During operation, the rotor distributes the incoming feed uniformly, creating a thin film on the heated surface. The film is intensely agitated as it travels down, transforming the material from solution to slurry, wet cake, wet powder, and eventually dry powder. The vapor generated rises in a counter-current direction, passing through an entrainment separator to separate droplets. The clean vapor exits the evaporator through the top vapor nozzle.
Agitated Nutsche Filter Dryers (ANFD) are versatile equipment used in various industries for solid-liquid separation and drying processes. They consist of a cylindrical vessel with a perforated plate (filter media) and an agitator system. The ANFD allows for efficient filtration, cake washing, and drying of solids under vacuum or pressure conditions. During operation, the slurry is fed into the vessel, and the agitator stirs the mixture, promoting filtration and cake formation. The filtrate is drained through the filter media, leaving a solid cake. The agitator then aids in washing and drying the cake, resulting in a dry and solid product. ANFDs are valued for their flexibility, productivity, and ability to handle hazardous or sensitive materials.
Vacuum Tray Dryer is a specialized drying equipment commonly used in industries for drying heat-sensitive and delicate materials. It consists of a rectangular chamber with multiple trays, heating elements, and a vacuum system. The material to be dried is spread on the trays, and the dryer creates a vacuum inside the chamber. The heating elements provide controlled heat, which evaporates the moisture from the material. The vacuum facilitates efficient drying by lowering the boiling point of the moisture. As a result, the drying process is gentle and prevents product degradation. Vacuum Tray Dryers are widely utilized in pharmaceutical, food, and chemical industries for effective and safe drying of sensitive materials.
Roto Cone Vacuum Dryer is a specialized drying equipment designed for efficient drying of wet solids under vacuum conditions. It features a conical-shaped vessel with a rotating agitator system and a vacuum system. The wet material is loaded into the vessel, and the agitator continuously moves and lifts the material, promoting even drying. Simultaneously, the vacuum system creates a reduced pressure environment, which lowers the boiling point of the moisture, aiding in its evaporation. The rotating action of the dryer ensures efficient heat and mass transfer, resulting in faster and uniform drying. Roto Cone Vacuum Dryers are widely used in industries such as pharmaceuticals, chemicals, and food processing for drying sensitive and heat-sensitive materials.
The Micronizer, also known as an Air Jet Mill, is a high-speed impact mill used for size reduction and micronization of various materials. It operates on the principle of particle-to-particle impact and uses compressed air or gas to generate high-speed jets that collide with the particles, causing them to break down into smaller sizes. The Micronizer's precise and controlled particle size reduction capabilities make it ideal for applications requiring fine grinding and uniform particle size distribution. It is widely used in industries such as pharmaceuticals, chemicals, and food processing for micronization, pulverization, and dispersion of powders, allowing for improved product quality and enhanced material performance.
