Arsenic removal

EP Minerals has been filtering beverages for the last 60 years, and now has developed a patented, NSF approved, arsenic adsorption media, NXT-2. The media has demonstrated removal results to less than 10 ppb arsenic to meet the new MCL. The lanthanum/ferric hydroxide based media can also provide additional benefits such as improved stability in the column to protect against possible desorption caused by pH upset.

The Fluoride Safety Sentinel 21 is a fully automated modular fluoridation system manufactured to inject fluorosilicic acid into the public water supply. Designed as a closed-loop system, the need for operating personnel to estimate daily flow rates, coupled with the possibility of human error, is eliminated. The standalone system instantaneously adjusts chemical feed rates with each change in supply flow rate or fluorosilicic acid concentrations. The system can be configured to meet the specific operating requirements of various municipalities.

Scaletron Industries has introduced its new Models 4042TM Spill Containment Scale and Model 4042WBTM Secondary Spill Containment ScaleTM for weighing chemicals in tanks, drums, intermediate bulk containers (IBCs) and tote bins. The scales weigh only the chemical dispensed into the water treatment system. If there is a chemical spill, the weight is still on the scale and doesn’t read as though it has been dispensed into the system. The scales have four load cells that are sealed in PVC and vinyl plastic enclosures, which means that they are protected from spilled chemicals and that the chemical containers do not have to be centered, balanced or leveled.

A new Bulk Bag Conditioner-Unloader System from Flexicon loosens bulk solid material that has solidified during storage and shipment, allowing the material to discharge through a bag spout. The integral configuration of the conditioner eliminates the time, labor and equipment needed for separate loading of bulk bags into a stand-alone conditioner. The design also consumes significantly less floor space than two separate pieces of equipment and requires less material and labor to construct, reducing initial cost.

Peristaltic pump

Watson-Marlow Bredel offers the 520 Series peristaltic pump for sodium hypochlorite handling. Entrained gas is pumped with ease, eliminating the occurrence of vapor locking that prevents conventional pumps from functioning properly. The series contain fluids within the tube at all times and never allows the sodium hypochlorite to come into contact with the pump mechanism. This helps provide predictable life costs for the pump as the tube is the only part that will need replacing.

Eclipse Actuators quickly close toxic gas valves on 150 lb. and ton cylinders in less than one second when activated by remote sensors. This actuator system will then provide a closed contact to signal that the valve is closed and sealed. The operator can then visit the site to correct the condition, check the gas connections, and manually reopen the valve to start the gas system. The Eclipse is a battery-operated actuator and allows an operator or remote gas sensor to shut off leaking toxic gas without requiring the operator to enter the hazardous atmosphere.
