Ceramic-based filtration is a state-of-the-art filtration technology that came about as an outgrowth of research in the nuclear power industry. While it has been well established that microfiltration and ultrafiltration are highly effective at removing particles to the sub-micron level, previous technologies have been limited by the chemical and temperature environments in which they can operate. Ceramic filters, however, are extremely robust.

CERA-CLEAR™ is a technology that can filter liquids to the sub-micron level, effectively clarifying, to a significant degree, a host of different streams high in COD/BOD (Chemical Oxygen Demand/Biochemical Oxygen Demand), TSS (Total Suspended Solids), TKN (Total Kjeldahl Nitrogen), O&G (Oil and Grease), and other insoluble or suspended materials, as well as some soluble matter. The principal of operation is cross-flow microfiltration or ultrafiltration using highly selective ceramic filters whose operating range is engineered for the targeted objectives. The CERA-CLEAR™ CRS™ system provides the ability to remove all but the smallest organic molecules or soluble ions.

The CERA-CLEAR™ CRS™ is ideal for recovering caustic solution where Clean in Place solutions are deployed.

PRODUCT FEATURES

• Greater than 99% removal of most contaminants and biologicals
• Chemically and biologically inert
• Resistance to extreme temperatures
• No chemical treatment required
• Resistance to concentrated acids, bases, & solvents
• Low initial equipment cost
• Low operating cost
• Low maintenance – ease of cleaning
• Long working life - measured in decades
• All stainless steel construction for piping, valves, and pumps.

Our ceramic elements do not wear out. Our systems use Clean In Place technology to maintain the elements.

• Our systems recover heat (energy) as well as caustic solution, virtually doubling the savings
• Because our systems are ceramic based, we can process streams at any temperature from ambient to boiling
• Energy, water and surcharges by municipalities will only increase, further increasing the recovery savings
• Our energy and caustic recovery is clear and measurable with our automated Digital Dashboard.
• Our systems are deterministic, based on science, chemical engineering and mathematics

Our A.I. AOS™ (Autonomous Operating System) is highly evolved, automated & scalable

• Our A.I. AOS™ control system is generations ahead of the competition
• Our highly evolved A.I. AOS™ monitors system performance, and every aspect of the system operation
• Operator interface is an intuitive 10.4" 65k color touch screen interface.
• Our A.I. AOS™ is remote access & monitoring capable to your PC, iPad, Android based  or mobile device
• Our Digital Dashboard provides messaging, alerts, & reports metrics for management and engineering staff

We have NO replaceable media

• Our systems remove all bacteria and do not go septic. Most bacteria cannot fit through the pores of our ceramic membranes. It is a matter of physics.
• Small physical footprint. Our small footprint relative to others; 4’ x 8’ cf. versus others’ systems of sand filters, carbon filters and additional tanks and pumps.
• Our system is extremely simple to install – four connections, all on the same side of the skid.
• Our CRS™ operates in concert with your existing Clean In Place (CIP) system  such as in semi-batch processing
• Caustic solution can be directly returned to a local or remote makedown tank or an intermediate tank for testing

INDUSTRY APPLICATION

CRS™  Caustic Recovery Solution

Porosities to 0.01 microns are now available, providing the ability to remove all but the smallest organic molecules or soluble ions. E3's Caustic Recovery Systems™ are ideally suited for recycling NaOH (sodium hydroxide) for reuse in CIP systems in a wide range of industries .

It is important to have confidence that bacteria cannot be passed through the filters. Ceramic membranes deal in absolute porosities.These types of contaminants cannot pass through our ceramic membrane elements because they exceed the pore size of our membranes.

Because of this selectivity, the CERA-CLEAR™ Ceramic Element Filtration™ is ideally suited for poultry and egg processing plants, dairy, beef and other agriculture or food processing plants where caustic solution is used.

Other Industry Application benefits:

• No chemicals used in the  recovery process
• No chemical cost, no chemical storage issues
• Reduces health safety, accident or exposures risks
• Lower plant caustic costs, due to re-using recovered caustic
• Significantly reduces discharge costs due to reuse
• Low energy cost. Only one pump used in the separation process
• Low maintenance cost, minimal administrative and  operator overhead
