TSID Unité des Installations de Drainage

With the Sewerage Unit, "TSID", tests about a wastewater sanitation system can be made and the flow in a sewage system can be observed.

A complete sewage system can be observed with the "TSID" unit. The collection of wastewater from a series of sanitary ware and appliances is simulated, since all water supplies must include a downpipe. The unit has ten toilet tanks at the top, a toilet with tank, a toilet with pressure flush, ventilation pipes and bypass pipes. All of them are controlled by the user with solenoid valves. The tank valves are activated by remote control.

The unit is intended for studying pressure and flow in different junctions, cross sections and traps, under different aeration and ventilation conditions.

The water circuit of the unit is closed and consists of a collection tank and a pump to recycle water.

Eight manometers are included to study pressure, they indicate the pressure development in the downpipe. Pressure is an essential part to study for the design of sanitation systems, since design errors lead to noise, blockages, etc. Besides, all the pipes are transparent to allow the flow process visualization.
