GREASE CONDENSING TANKS

The detergents and the grease contained in the domestic sewage slow down and block the depuration processes inhibiting the activity of the microorganisms. For this reason it is important to provide a drainage system only used for the discharge of white waters ( sink drainage, washbasins, washing tubs, washing machine, dishwasher, bathroom water drainage, bath, shower, washbasin, bidet). The white waters used can be thus treated with a grease condensing tank, while the toilet drainage is treated with an Imhoff tank.
The grease in the water and the lather of the detergents are separated and carried separately to these two different products, made up of a circular or rectangular tank divided into compartments: the bulky residues of food that can go through the sink drain and a high quantity of grease and floating lather are collected in the first compartment.
In the second compartment another quantity of grease is collected after going through a siphon; in the third compartment, after the passage through another siphon, the water depurated from the high concentration of detergents mixed with the grease goes out to the absorbing well, the sub- irrigation treatment, the water sewage or to any further treatment of depuration.

The grease condensing tanks are made according to the typology and the amount of sewage to be treated.
Particular consideration is paid to the surface area of the amount and to the liquid head necessary to separate the sedimentable solids and the floating particles. In order to optimise the separation of the grease and the detergents, the retention times have to be ample enough . In this way we can obtain an almost complete cooling of the sewage and thus the condensation of the grease and the lather. Moreover the separation through different compartments inside the tank permits to reduce the turbulence caused by the inflow of liquid and create the proper situations for a successful process.

Description

1. Deposit of the sewage
2. Deposit of heavy sludge
3-4. Suspension of emulsible grease
E. Incoming of water to be depurated
U. Outcoming of clarified water

Our range of products includes circular tanks of diameter cm. int. 60, 80, 100, 150, 200, 234 and rectangular tanks cm.int. 300x200 used mainly to treat sewage coming from canteens and restaurants.
The tanks with a 100 and 150 cm diameter are also produced in monoblock of 100 cm high instead of 50 cm high modules.

Monolithic grease condensing tanks with sides of 16 cm thickness and internal measurements of cm 200x300, 200x400, 200x500, are also produced if requested.

 

Warnings. Considering the treated waters it is advisable to frequently clean and empty the system as well as the other depuration systems. It is advisable to use a breather pipe on the inlet duct of the sewage to depurate and to fill the product with clean water after each emptying operation.
