Peristaltic Pumps

peristaltic pumps are the simplest possible pumps, with no valves and seals. The fluid contacts only the tubing, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic pump can operate dry without risk. Backflow and siphoning do not occur.

the flow rate depends mainly on the internal diameter of the tube and the speed at which the roller advance. Suction lift capability depends on the restitution power of the tube. The best way to select the tube is first determine which materials are chemically suitable and then to choose the one that best matches of significant pressure, suction or vacuum demands.

persitaltic pumps are used in the field of pharmaceuticals, food processing, chemicals, inks & pigments, cell culture, filteration and seperation, pollution control, beverage dispensing, photo processing and printing, fermentaion, heat treatment, etc.

Interface RS 232

Description

The sensor system is a 6 sample system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintain-ing a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurements.

Biochemical Oxygen Demand (BOD)

BOD – biochemical oxygen demand – is an expression for the quantity of oxygen required for biological degradation of organic matter in a waste water sample. BOD measurement is therefore used as a basis for the detection of biologically degradable organic matter in water. The difference between BOD and chemical oxygen demand (COD) is that COD additionally registers biologically non-degradable organic matter.

BOD measurement is therefore an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points.
