Chemical Pumps: Zero Liquid Discharge in Surface Treatment Shop

From Savino Barbera SNC

A surface treatment shop employing "zero liquid discharge" is a manufacturing shop which does not discharge any waste water into the sewerage or surface waters. Zero Liquid discharge does not mean that the treatment shop does not produce any liquid waste. It means, on the contrary, that the produced liquid waste must be considered as special waste and confined to authorized companies for special waste treatment. The set up of the zero liquid discharge implies the overcoming of technical issues and high costs. These efforts can be justified by a reduction of the environmental impact of the surface treatment shops and, on the other side, by the nowadays difficulties of the shop's owners to undergo a very strict regulation:Limit values for concentration and flow of effluents

Magnetic Drive Pumps
Magnetic drive pumps are sealless pumps that use a coaxial magnetic coupling to transmit torque to an impeller. A standard electric motor drives a set of permanent magnets that are mounted on a carrier or drive assembly.
Centrifugal Pumps
Centrifugal pumps consist of a set of rotating vanes, enclosed within a housing or casing, that are used to impart energy to a fluid through centrifugal force.
Self Priming Pumps
Self-priming pumps create and maintain a sufficient vacuum level to draw fluid with no external assistance
Chemical Pumps
Chemical pumps are designed for applications requiring greater reliability and durability than conventional pumps.
Double Diaphragm Pumps
Double diaphragm pumps are positive displacement pumps that compress fluid by decreasing the volume of a chamber containing the fluid.
