1.  SolmeteX, Inc, makes several amalgam separators that remove both particulate and dissolved Hg. They are based on Keyle:X© resin, a thiol based mercury sorbent that has one of the highest capacities for any non-carbon material (3.4 eq/liter). It functions in pH ranges from 1 to 14 and has a binding constant of 10(29).

4 to 5 chair dental clinics. 
The system works on the vacuum 
side of dental suction systems 
and removes both particulate and "dissolved" Hg.


The cost for the Hg5© system pictured at right is $695.00. Replacement cartridges cost $150.00. The Recycling of used cartridges is covered in the cost of the system. The system easily fits into the confined spaces of many dental operatories and requires no electricity to operate. SolmeteX, Inc. also makes systems that handle larger clinics. A SolmeteX Hg20© system is installed in the Tri Service dental clinic in the Pentagon.



SolmeteX, Inc. Hg20® system for large dental clinics. This system is installed in the Tri Service dental clinic located in the Pentagon, Washington DC. The system pumps the effluent from the air/water separating tanks of the dental vacuum system into a treatment tank where oxidation takes place. The oxidized wastewater is then pumped through a series of cartridge filters and Keyle:X® resin. Prototype systems have been tested at the Naval Dental Center, Great Lakes, Illinois and at the Branch Dental Clinic, Ingleside, Texas.
