HF-PCS - Vacuum Distillation Unit Type A

Simply the act of separating water from contaminants. Water reaches its boiling point and is evaporated away leaving the non-vaporized substances behind. Distillation has been in use for centuries. HF’s Low Temperature Distillation system evaporates the water in a vacuum reducing the boiling temperature to below 100 degrees F (38 °C).

Also called Vacuum Evaporation and Cold Vaporization, this technology is a relatively simple and robust method of purifying water. Contaminants are collected or reclaimed in this process by drawing the influent into a chamber (under vacuum) where evaporation occurs. The least volatile contaminants and solids remain in the chamber. The distillate is then collected for discharge, sent for additional treatment or re-used. This is a closed system and there is no exposure of either the purified water or the concentrate to the atmosphere.

What advantages does it offer?

• Enables the use of economical and durable materials such as aluminum alloy for heat transfer tubes, plastic process piping and epoxy-painted steel tanks.
• Ability to use low cost/low-grade heat available through cogeneration to even more environmentally friendly.
• No tube scaling issues associated with high temperature distillation systems and atmospheric evaporators.
• Low energy costs because the heating and cooling is achieved using the compression cycle.
• Minimal requirements for intake and pretreatment systems.

Economics of this technology are enhanced in two ways:

1. The concentrate may be retrieved for reuse, and/or recycling.
2. The condensed water may be recycled.

The tradition of research and technological innovations at HF provide important advantages to our customers and this is underlined by the constant effort in presenting new models, patents and plant designs.

HF’s patented technology that enables us to achieve higher concentrations of solvents that can then be economically sent for refining.

Our state of the art distillation systems are self contained. This means you will not have to add any extra ventilation to your facility to remove excess heat created by typical Vacuum Distillation Systems. You’ll have no worries about plumbing in other components due to this self-contained design.

Designed around the Allen Bradley SLC 503 series, with integrated touch screen, control and real time monitoring, system navigation is a breeze and all information about system operations is fully accessible from the screen. Operation and alarm situations are easily identified and corrected. Also included is an industrial modem that allows us to troubleshoot programming changes and process parameters remotely.

Using HF’s systems design approach and with particular attention paid to heat balance and ongoing operational costs, we have integrated the most energy efficient Heat exchangers on the market today with U values up to five times higher that other manufactures heat exchangers.

NEMA 4X Wash-Down Rated

Our skids can be used indoors and out, do not corrode and are unaffected by dust and hosedirected water. Fiberglass enclosures, Stainless Steel construction, electrical components and controls are all carefully selected to satisfy the most demanding requirements.

HF has waste treatment experience with a wide array of organic (and many inorganic) compounds found in industrial water, municipal water, groundwater, and landfill leachate.

Treatment Includes:

The proper match of process with compounds. Compounds vary greatly in their susceptibility to different processes. HF Group engineering has the experience and is equipped to test for and deliver systems based on the following three technologies, Membrane, Advanced Oxidation, and Vacuum Distillation.

Complex wastewaters will often require more than one process for cost-effective treatment and HF is uniquely qualified to test and deliver integrated treatment systems. The most effective water or groundwater treatment approach is selected through a comprehensive testing program to ensure the full-scale implementation will match laboratory results. HF has a complete lab with batch and continuous flow apparatus to test your water under realistic conditions (using bench scale and pilot scale testing) and develop the most economical process solution for your unique needs.
