Caloris Water Reuse
he reuse of industrial water involves:
- Purifying process wastewater to create a clean water source that meets the requirements of the reuse application
- Handling the concentrated solids stream that results from the purification process to enable:
* safe discharge/disposal, or best case,
* creating a product of added value to the customer.
Caloris’ History with Reuse
aloris has been in the business of concentrating solids and creating pure water to reuse in customer processes for more than 10 years.
rom food product evaporators, where the condensed water vapors are polished by membranes to meet Category 1 standards, to general plant effluent systems that generate clean utility water sources, Caloris has a history of dealing with challenging reuse opportunities.
Why Water Reuse?
ustainability—managing a critical and increasingly limited resource. Consider:
- Sound actions taken now will position your organization for responding to future water constraints.
- Adequate water supply can no longer be taken for granted. Increasing population and industrial activity have stressed water supplies in many geo-graphies to the point where even moderate drought periods put adequate supply at risk.
- Social responsibility, consistent with the organization’s environmental values and vision.
educed cost—depending on the charged cost for fresh water supply and effluent water discharge at a site, a water reuse program could provide an overall cost savings.
egulatory compliance—meeting regulatory discharge requirements often means use of treatment technologies that create a clean water stream suitable for reuse.
otential uses for recovered water include cooling tower makeup, cleaning/sanitation, boiler makeup, process water and production water.
How It Works
here are numerous methods for capturing clean water from your effluent stream. Evaporation recovers water (often 90-95% of the original stream) in the form of steam that can be condensed and reused. Membrane filtration can be used to pre-concentrate solids (and generate clean water) ahead of an evaporator or to polish condensate from an evaporator. Our Thin Film Dryer can then take the saturated evaporator concentrate all the way to a dry powder, opening the door to more reasonable disposal options.
Any Style, Any Size
aloris offers multiple types of processing systems that can fit in any size space. From compact evaporators to skidded membrane systems, we will work with your facility’s team to tailor a system to your needs and your desired footprint.
Pilot Testing Available
end Caloris a sample of your wastewater and we will determine the right treatment system to process your waste stream. An on-site test with one of our pilot evaporators or our pilot membrane filtration unit also can be arranged.
Zero Liquid Discharge (ZLD) Systems
n addition to capturing clean water for reuse, there may be other recoverable substances that can be separated from the stream for potential use (cleaning products, nutrients, etc.). Interested in a system that will allow you to recover product from your waste stream for reuse, as well as usable clean water? Caloris engineers will work with you to develop a custom zero liquid discharge system to accomplish your goals.
