Automatic DI Bank Switching and Data Acquisition Controller

Res-Kem has developed an integrated DI Bank Switching and Data Acquisition Automation Controller. The system monitors the inlet and outlet resistivity and the flow rate. At one of several alarm points, the system will send a text message to any number of email addresses and mobile devices. As part of a service agreement with Res-Kem/General Water, the system will warn Res-Kem/General Water personnel to prepare for a replacement of the soon to be exhausted bank of DI bottles.

Depending upon the system programming the bank will attempt to rinse to quality in several stages. If it does not succeed, the bank will switch to a standby bank and notify Res-Kem that the bank is exhausted fully and needs to be changed out.

The reason why Res-Kem developed this product is many people were having problems getting replacement parts and proprietary circuit boards for the excellent product called the Aquaswitch II a registered trademark of Myron L. Also, with reduced staffing at most of our customers, people do not have the time to monitor a stack light or resistivity monitor. As a result, the quality can be poorer than required potentially damaging down stream processes and products.

Tiny Particles Fight Giant Water Problem

Many of you may have heard of the chemicals that are in our drinking water including drugs, antibiotics, and other very small and difficult to remove chemicals. These can cause health effects at very low levels. Some disrupt the hormone systems of humans and wildlife, posing threats to fetal development and young children. Sources include birth control pills, prescription drugs, antibiotics, cosmetics and fragrances. People take the drugs and excrete them in urine.

In the online article "Pollutant-Fighting Particles Purify Water" in Lab News Daily by Laboratory Equipment, it briefly describes the continuing R&D project by two Charlton University professors to bring this technology to municipal and industrial waste water treatment plants. It will be interesting to see how they plan on removing the particles from the treated waste water in a cost-effective manner.

Deionizer/Demineralizer System with Packaged Design Introduced

Res-Kem recently introduced packaged DI Water Systems for Commercial and Light Industrial applications. The OHM-TECH Series two-bed deionizers for commercial and light industrial applications are designed for semi-automatic production of water with a conductivity of less than 10 micro-ohms and feature:

• Flow rates from 1 - 40 gpm
• Ion exchange Capacities from 9,000 - 90,000 grains.
• Strong acid cation and type 1 strong base anion resins.
• Microprocessor based control system with conductivity monitor and flow sensor for regeneration initiation.
• Corrosion resistant fiberglass electrical enclosures which reduces maintenance costs.
• Resin vessels are polyethylene-lined fiberglass.
• ASME code vessels.
• Factory assembly and skid mounting for quick installation and minimum startup cost.
• Schedule 80 PVC piping package using a multi-function hydraulically operated composite valve.
• Metering valves for accurate and safe control of regeneration water and chemical introduction.
• Internal distributors are corrosion resistant, designed for optimum efficiency.
