Achieving Compliance for Wastewater Treatment... Continued from page 30
ing include using a filter press or ro- tary drum vacuum. When dried, the
resulting solids will pass the TCLP leaching test and are considered non- hazardous.
These treatment systems are
available in batch, semiautomatic, or fully automatic versions and can be designed to be part of a closed loop sys- tem for water reuse or to provide legal- ly dischargeable effluent suitable for disposal in municipal a sewer system. A new, fully customized system is not always required. In many cases, it can be faster and more cost-effective to add to or modify a facility’s current wastewater treatment systems when this is feasible. Because every wastewater
stream is unique to its industry and application, each wastewater treat- ment solution must be specifically tai- lored to the application. The first step in evaluating the potential cost sav- ings and effectiveness of a new system is to sample the wastewater to deter- mine its chemical makeup. This is fol- lowed by a thorough review of applica- ble water authority requirements. The volume of wastewater that will be treated is also analyzed, to determine if a batch unit or flow-through system is required. Other considerations in- clude size restrictions to ensure that the system fits within the facility’s available footprint.
Separating Agents Critical to the success of any au-
tomated wastewater treatment sys- tem is the use of an effective and ef- ficient separating agent. This agent can attract and bind dissolved con- taminants and encapsulate suspend- ed contaminants to allow rapid sepa- ration from treated water. Sabo Industrial Corporation, a
New York-based manufacturer of wastewater treatment equipment,

uses CLEARTREAT® bentonite-based separating agents manufactured by Wyo-Ben, Inc. These separating agents are formulated to break oil and water emulsions, electrochemically adsorb and sequester dissolved met- als and other positively charged con- taminates, create metal hydroxide precipitates, and yield easily dewa- tered clay flocs that encapsulate sus- pended solids for rapid removal. Bentonite has a large specific
surface area with a net negative charge that makes it a particularly effective adsorbent and ion exchange medium for wastewater treatment applications to remove dissolved metals and other charged chemicals. Bentonite also creates durable
flocs that effectively encapsulate sus- pended materials. This can usually be achieved in one-step treatment, which lowers process and disposal costs. In contrast, polymer-based products create very weak flocs that allow encapsulated waste materials to easily leach back out over time or upon further agitation. Today’s automated systems,
along with highly effective CLEAR - TREAT separating agents can provide semiconductor manufacturers with a simple, cost-effective alternative for treating wastewater to comply with local, state and federal regulations. Al- though there is a cost to these sys- tems, they do not require much atten- tion and can easily be more economical than paying fines or hauling. Contact: Sabo Industrial Corp.,

Epoxy Technology Expands Line of
Biocompatible Adhesives
Billerica, MA — Epoxy Technology has added two new products to its MED lineup — MED-OG198-55 and MED-730-110. All 25 EPO-TEK®
MED line adhesives have successful- ly undergone ISO10993-5 Cytotoxici- ty testing, a screening test for bio- compatibility. Nine products have undergone extensive additional test- ing passing ISO 10993-4,5,6,10, and 11 testing. The company’s newest MED
line products have unique properties, which may be helpful in critical de- sign challenges. MED-OG198-55 is a cationic-based, translucent, highly thixotropic gel with significant UV shadow-curing capabilities and en- hanced performance when thermally post-cured. The gel is especially useful in
microfluidic designs, where its thixotropic nature helps to prevent flow to specified areas. It is used in staking electrical and optical compo- nents, reinforcement, feed through and sealing selected areas in drug delivery products. MED-730-110 is an easy to use
(1:1 mix ratio, dual-cartridge packag- ing), structural adhesive, with low- or room-temperature curing capabili- ty. It offers excellent adhesion to plastics, catheter tubing and many known difficult-to-bond materials, especially PEBAX®. Contact: Epoxy Technology, Inc.,
