Grease trap

The waste water from the hotel, catering and restaurant sector or from commercial kitchens are heavily loaded with fat and other organic residue such as starch or proteins. In general, their hydrophobic needs requires the fat to be physically separated from the water via a grease trap. This process generates very high volumes of fat to be regularly removed (general frequency: every 3 months).

The grease trap is designed to retain the fat, which is lighter than water, when removing the waste water from kitchens. The means of retaining the fat involves baffles which block the fat's passage or small grease traps placed in a series.

Traitement des eaux

A grease trap needs significant and costly maintenance:

It has to emptied regularly - about every 3 months ;
It sometimes has to be unblocked;
It has to be cleaned when it overflows;
It has to be deodorized when foul smells are released.

The solution offered by REALCO is the injection of a solution using environmental biotechnologies.

It consists of the injection of the CPL range liquid product.

This involves enzyme- and bacteria-based liquid formulations specific for the treatment of waste water heavy in organic residue. The products in the CPL range contain a wide spectrum of enzymes (protease, lipase, amylase and cellulase) and a bacterial concentration (3.107 CFU / ml) specific for the metabolization of organic matter and particularly fatter matter.

Treatment of undersized or overloaded water treatment plants

An undersized or overloaded water treatment plant is one whose initially forecast water treatment performance does not meet current needs.

Objective: to reestablish an optimal water treatment performance.

Problems: increase in the pollutant load (PE), high maintenance cost, legally unacceptable discharge standards, etc.

Enzymes offer THE solution.

Enzymes are proteins which break down the organic macromolecules into smaller components, making them water-soluble and more easily assimilable by the bacteria.

=> The enzyme-based products (CPL range) accelerate and optimise the hydrolysis phase: absorption by the bacteria is facilitated and the purification is of a better quality.

Septic tank or institutional water treatment plant

The problem??

Blackwater normally has a high bacteriological load characterised in particular by intestinal flora germs; these micro-organisms are the main source of the bacterial flora which break down organic matter in the septic tank.??

Demographic growth, the improvement in housing, hygiene and comfort have the direct consequence of increasing water needs and, as a result, increasing the volume of domestic waste water.

The more and more intense use of detergent, descaling, disinfectant or antibiotic products which inhibit the work of the natural bacteria, alters the smooth running of the facilities.
The undersizing of facilities, in 90% of cases, results in frequent clogging, instances of overflowing, odours, pipe breakages which mean high maintenance costs.

The solution??

According to the studies carried out by our R&D department, it is accepted that all of these problems can resolved by introducing enzymes and bacteria.

1. Enzymes: ?

The organic matter (fat, meat, sugar, etc.) emanating from waste water can be easily hydrolysed (fatty acids, glycerol, amino acids, glucose, etc.) by the enzymes and can therefore be assimilated more quickly by the micro-organisms.

2. Bacteria: ?

A regular introduction of purified micro-organisms selected for their ability to develop in an environment like a septic tank, allows the bacterial work to be continued within the tank.?

Nowadays, because of the significant aggressive demands placed on the septic tanks, only a regular introduction of ENZYMES and BACTERIA guarantees that they operate properly, i.e. they give purifying effectiveness, remove the need for emptying and remove clogging.??

REALCO has selected micro-organisms capable of developing in such environments and, thus, of breaking down organic matter.?To these micro-organisms, we add enzymes which will firstly liquefy the fatty matter; and they will thus speed up and facilitate the work of the bacteria.

Applications

A septic tank is a tank which separates and ferments the organic matter which passes through it. The heavy particles will be deposited on the bottom to form the bacterial bed (activated sludge), while the lighter ones (fats) accumulate on the surface to form the scum layer.?

An anaerobic fermentation (action of the bacteria living in an environment deprived of oxygen) liquefies the organic matter present on the surface and in the bottom of the tank.??

When the tank malfunctions, the layer of accumulated matter increases, filling the tank and causing the problems mentioned above.

Directions for use

Manually: at as early a stage as possible, i.e. via a toilet or a wash basin which is the furthest from the septic tank.
Automatically: via a dispensing pump, on the earliest possible part of the main pipe.

Dosage

1. Unblocking - Start-up:

In order to start an E/B treatment under optimal conditions, it is recommended, before any treatment, that the tank is emptied. ?However, it is possible to restart a facility using enzymes. The enzymatic hydrolysis renders the organic matter soluble, making it more easily and more rapidly assimilable by the bacteria.

Start-up:?

500 g /m3

Unblocking:??

CPL-50: shock dosage: 500 g /m3;?
Preparing a solution: 500 g / m3 of CPL-50 in 10 L of warm water (40 °c);?
Take out the equivalent of a wheelbarrow of sludge from the septic tank;?
Mix the solution with the sludge taken out;?
Pour the mixture into the septic tank by making holes in the crust;?
Then regularly maintain the tank.

2. Maintenance:

1g / user / day ?(for an undersized septic tank).
25 g / user / day ?(for a correctly sized septic tank).
