Inventor: MEYER GERHARD DIPL ING
IPC: B65H1/26
Filed: 1990-04-25
Abstract: The device includes a supply device (26) by means of which the stack (6) supplied to the lift table (5) can be brought into a predetermined zero starting position on same.

Title: Procedure and device for pre-clearing waste liq. such as pig slurry - after removal of coarse solid material, water undergoes ozonisation and electrolysis in prepn. for biological treatment
Inventor: GESSLAUER RUDOLF
IPC: C02F1/465
Filed: 1991-02-11
Abstract: In a procedure for cleaning waste water, coarse solid particles are separated (3) from the water, which is then subjected to ozonisation (12,16-18) and electrolysis (20-25) until it reaches a quality which is suitable for biological treatment. The ozonisation and electrolysis are carried out simultaneously. The ozone is introduced into the water with a partial pressure which is such that the gases already present in the water are removed by stripping. The foam produced by this procedure undergoes a solid/liquid separation and the liquid component is returned to the waste water. The quality of the water is continuously supervised. Separation of the coarse solid component takes place before ozonisation and electrolysis. Solid particles recovered during the ozonisation and electrolysis are also removed from the water. USE/ADVANTAGE - Used in the treatment of waste water, and esp. difficult waste water containing considerable quantities of dissolved oxidisable substances, especially heavy metals, as well as antibiotics, detergents, toxins, salts, acids and alkalis etc., such as for example pig slurry. Difficult waste water is treated so that it can be fed directly into a biological treatment unit. The process is quick, simple and inexpensive and operates independently of the characteristics of the waste water

The first spring is of lower rigidity for idle running and has only a small length. The space inside the coupling is available for the second spring acting over the main operating range without being significantly impared by the first spring. @(14pp Dwg.No.1/6b)@
