Description du produit

In various industrial processes, concentrating liquid solutions or treating wastewater containing heat-sensitive components, high boiling point solvents, or valuable recoverable materials presents a significant challenge for conventional evaporation methods. High temperatures can degrade sensitive products, consume excessive energy, and often fall short of desired concentration levels. The Low Temperature Vacuum Evaporator is a state-of-the-art solution specifically designed to overcome these hurdles, offering an efficient, gentle, and energy-saving method for liquid concentration and advanced wastewater treatment.

The Innovative Principle of Low Temperature Vacuum Evaporator

The core innovation of a low temperature vacuum evaporator lies in its ability to significantly reduce the boiling point of water or other solvents by operating under vacuum conditions. At atmospheric pressure, water boils at 100°C (212°F). However, under a vacuum, the boiling point can be lowered drastically, often to temperatures as low as 30-40°C (86-104°F) or even lower, depending on the vacuum level. This principle allows for the evaporation of water or solvents at temperatures that are gentle enough to preserve heat-sensitive materials, making it ideal for industries like pharmaceuticals, food & beverage, and fine chemicals. The evaporated vapor is then condensed, recovering pure distillate water, while the concentrated liquid (or sludge) remains.

Key Benefits for Complex Liquid Concentration and Wastewater Treatment

The application of a low temperature vacuum evaporator brings a multitude of advantages to industrial processes:

  • Preservation of Heat-Sensitive Materials: Gentle operating temperatures prevent thermal degradation of valuable or delicate components in the solution, maintaining product quality and efficacy.
  • Significant Energy Savings: Lower boiling points require less heat input, leading to reduced energy consumption (often utilizing waste heat or heat pumps for further efficiency) compared to atmospheric evaporation.
  • High Concentration Factors: Capable of achieving very high concentration ratios, minimizing the volume of waste requiring disposal or maximizing the recovery of concentrated products.
  • Treatment of Challenging Wastewaters: Effectively treats industrial effluents with high TDS (Total Dissolved Solids), heavy metals, complex organic pollutants, or high COD/BOD, converting them into pure distillate and concentrated residue.
  • Resource Recovery: Enables the recovery of valuable components (e.g., salts, chemicals, active ingredients) from waste streams, transforming waste into usable resources.
  • Reduced Wastewater Disposal Costs: By drastically reducing the volume of liquid waste, disposal costs are significantly minimized.

Stark Water’s Low Temperature Vacuum Evaporator is engineered with precision heat exchangers, robust vacuum systems, and automated controls to ensure continuous and efficient operation. Its modular design allows for customization based on specific evaporation capacity and liquid characteristics.
