ROTOTEC & SYSTEMGROUP System Group was created in a small town inland of Mi Plastic Romania). The group further reinforced its Pesaro (Lunano) as a result of an idea by entrepreneur Alvaro Boscarini who, in 1979, had founded Centraltubi for the production of polyethylene pipes. The group was formed at the start of the 1990's when Centraltubi was joined by Futura, a company operating in the pipe fittings, accessories and specials market. These were to be the first steps on the road to success which, in the following years, saw the birth of five other important businesses: Sa.Mi Plastic (smooth...

SEWAGE DIVISION CALCULATION OF POPULATION EQUIVALENT The concept of Population Equivalent (PE) is useful for expressing the load on a treatment plant from a particular user in standard terms comparable with domestic users. The equivalence can refer to the hydraulic load, to the load in suspended solids or, more commonly, to the organic load expressed as BOD5. Population Equivalent is a conventional concept based on the mean contribution from a typical user equal to 60 g/BOD5 per inhabitant (Law Decree 152/2006). It is also particularly useful in that it allows a simple comparison to be made between...

SEWAGE DIVISION GREASE SEPARATORS SPECIFICATIONS TECHNICAL CHARACTERISTICS The grease separator is a physical pre-treatment process that removes oils, foams, greases and all substances of specific weight less than that of the effluent. The grease separator is nothing more than a stilling tank in which the substances of specific weight less than water are separated by floatation (surface). Sedimentation also takes place, with a part of the suspended solids depositing at the bottom of the tank. Primary treatment of grey water from kitchens, washbasins, bidets, showers, baths, washing machines and...

ABOVE-GROUND GREASE SEPARATORS TECHNICAL CHARACTERISTICS the grease separator is a physical pre-treatment process that removes oils, foams, greases and all substances of specific weight less than that of the effluent. The grease separator is nothing more than a stilling tank in which the substances of specific weight less than water are separated by floatation (upward flow to the surface). Sedimentation also takes place, with a part of the suspended solids depositing at the bottom of the tank. Its reduced width allows it to be carried through doorways. In this way, it can be installed in a suitable...

SEWAGE DIVISION GREASE SEPARATORS TECHNICAL SECTION - GREASE SEPARATORS TECHNICAL CHARACTERISTICS The grease separator is a physical pre-treatment process that removes oils, foams, greases and all substances of specific weight less than that of the effluent. Greases and oils produced during normal domestic activities derive from the consumption of butter, margarine, lard and vegetable oils. They also originate from waste meat and vegetables and from some cosmetic products. Greases are insoluble in water and have a low density. In the presence of surface-active agents (detergents), they create...
