ArsenicGuard™ Online Arsenic Analyzer

Introducing ArsenicGuard™, the first fully automated, online arsenic analyzer for monitoring drinking water arsenic levels.

As of January 2006, EPA regulations require drinking water arsenic levels not exceed 10 parts-per-billion (ppb). This significant drop from the previously acceptable level of 50 ppb requires municipal water companies to assess and implement arsenic treatment technologies to provide their customers with safe drinking water. ArsenicGuard provides online arsenic monitoring to 1ppb levels for drinking and ground water to effectively manage arsenic removal processes and reduce treatment costs.

ArsenicGuard provides complete process control for all arsenic monitoring applications:

Arsenic Removal Media

With the flexibility of monitoring up to four sample streams, ArsenicGuard performs process monitoring throughout your entire arsenic removal system. Check the initial arsenic levels of your incoming raw waters. Ensure the integrity of your arsenic removal media by verifying performance is to compliance levels. Delivering accurate, real-time results, ArsenicGuard enables monitoring of arsenic levels right up to media breakthrough. Maximize your media lifetime and lower costs by determining precisely when the media requires replacing or rejuvenation. Create your own costsaving, “customized” media replacement/rejuvenation schedule with databases built from actual measurements taken within your own facility rather than relying on the typical “manufacturer suggested” schedule.

Well Blending

Determine precise combined arsenic levels during blending of waters from various wells.

Effluent Quality Assurance

Eliminate costly fines by ensuring effluent arsenic levels do not exceed regulatory limits.
