Abstract

A separator for separating particles, especially amalgam particles, from effluent liquid obtained from the suction apparatus of a dental office, preferably driven by a common vacuum pump, includes a sedimentary deposit tank for sedimentation of solid particles in the effluent. A surge tank is provided for accommodating effluent overfill and providing its effluent output to the sedimentary deposit tank. A bypass conduit is connected in parallel with the separator and to a vacuum check valve in the vicinity of the separator inlet port for passing air into the separator when the suction apparatus is closed to ambient air, so that whenever the vacuum pump is operating, air is sucked into the separator either through the suction apparatus thence into the separator inlet port or via the vacuum check valve. The surge tank preferably has a liquid level sensor and associated warning device. An auxiliary filtration device may be connected downstream of the sedimentary deposit tank, and both of these units are preferably removably replaceable as modular units.
Provision is made for optional auxiliary equipment to improve filtration and to accommodate a positive air pressure source. A full tank drying facility is optionally provided.
