Instructions: Imagine you are a consultant working with a pharmaceutical company that needs to treat wastewater containing high levels of salts and organic contaminants.
Task:
Unitech evaporators can be used to concentrate the wastewater, effectively removing a significant portion of the water content. This process reduces the volume of wastewater requiring further treatment. The concentrated brine stream can then be fed into a Unitech crystallizer.
The crystallizer would selectively remove and recover valuable salts from the brine, reducing the overall salt content in the wastewater. This process can also be used to separate and purify specific salts based on their crystallization properties. The remaining organic contaminants can then be further treated using other appropriate methods.
Benefits of using Unitech technologies in this scenario include:
Environmental impact:
This solution significantly reduces the volume of wastewater requiring disposal, minimizing the burden on treatment facilities and reducing the risk of contamination. The recovery of valuable salts also promotes resource conservation and reduces reliance on virgin resources. However, it is crucial to ensure proper disposal of any hazardous byproducts and manage emissions generated during the process to minimize environmental impact.
Chapter 1: Techniques
Graver's Unitech systems employ several advanced separation techniques to achieve efficient water treatment and resource recovery. These techniques are crucial for the high performance and versatility of their evaporators and crystallizers:
Evaporation: Unitech evaporators utilize various evaporation methods tailored to specific applications. These include:
Crystallization: Unitech crystallizers leverage controlled crystallization processes to separate and recover valuable components from the feed solution. Key techniques include:
Salt Rejection: A critical aspect of both evaporators and crystallizers is the efficient rejection of salts and other impurities. Unitech systems achieve high salt rejection rates through optimized designs and the selection of appropriate materials.
The combination of these techniques allows Unitech systems to handle a wide range of feed compositions and achieve high levels of water recovery and product purity.
Chapter 2: Models
Graver offers a diverse range of Unitech evaporator and crystallizer models designed to meet the specific requirements of various industries and applications. The selection of a specific model depends on factors such as feed characteristics, desired capacity, energy constraints, and environmental regulations. Some key model considerations include:
Evaporator Models: Unitech evaporators are available in various sizes and configurations, including single-effect and multi-effect systems, depending on the required evaporation capacity and energy efficiency targets. Specific models might be optimized for specific feed streams, such as those containing high concentrations of salts or organic compounds.
Crystallizer Models: Similarly, Unitech crystallizer models cater to different needs. The choice depends on factors like the desired crystal size distribution, the solubility of the target product, and the level of process control required. Options include different vessel designs (e.g., agitated vessels, fluidized bed crystallizers) and cooling or evaporation methods.
Customization: Graver often customizes Unitech systems to meet specific client needs. This may involve modifications to existing models or the design of entirely new systems to optimize performance for unique process requirements.
Detailed specifications and performance data for each Unitech model are available from Graver Technologies.
