The responsible choice for treating institutional – industrial – urban water

  • ENZYME = the key to purification
  • ENZYME = purification accelerator
  • ENZYME = converts into residue easily assimilable by microorganisms
  • ENZYME = guarantees efficient metabolisation
  • ENZYME = biology under control
  • ENZYME + BACTERIA = synergy for effective purification

Only the enzyme acts as a purification accelerator. The enzyme removes the need for the limiting hydrolysis stage and accelerates the kinetics of the purification process.

Product:

CPL- 50 is an enzyme-bacteria complex recommended for waste water treatment. Enzymes are selected for their specific action on organic matter. Their role is to break down organic macromolecules into small molecules that are easily assimilated by micro-organisms.

Application:

CPL-50 is effective in all the following biological purification processes:

  • increasing effluent biodegradability
  • increasing effluent treatability
  • increasing purification efficiency
  • treating fatty matter (see Lipamax process)
  • liquefaction (crust, organic matter accumulation)


Application conditions:

1. Type of effluent
    a. Organic matter
    b. Biodegradable, DCO/DBO5 < 3
    c. Municipal treatment stations or food industries
    d. Use rate > 5000 mg/L
    e. If objective = hydrolysis: Residence time = a few hours
    f. If objective = metabolisation: Residence time ≥ 72 H

2. Effluent characteristics
    a. 5 < pH < 9
    b. 10°c < t° < 60°c

3. Presence of pollutants
    a. Oxidants, disinfectants, hydrocarbons, salt, Pb, heavy metals … at very low concentration
    b. Cleaning or disinfectant products used normally are not limiting.

4. Type of installations
    a. If a simple retention tank
            i. Agitation required
    b. Physicochemical, where unblocking / declogging is needed
    c. Biological


Lexicon:

Enzyme: enzymes are proteins present in the cells of all living things. Their function is to facilitate naturally occurring chemical reactions

Bacteria: the smallest unicellular living thing
Microorganism: term encompassing bacteria, yeasts, … all living organisms

Biodegradability: capacity of the pollution load to be microbially broken down

Treatability: how quickly the pollution load can be broken down

DCO: Chemical Oxygen Demand = the overall amount of oxygen needed to oxidise the entire pollution load

DBO5: Biological Oxygen Demand = the overall amount of oxygen needed to break down the biological part of the pollution load

Discharge rate: quantity of water discharged/unit of time

Load: calculated using the COD, it is the COD value multiplied by the discharge rate

Grease removal tank:



Waste water from catering or institutional kitchens has a high fat load and a high proportion of other organic residue such as starch or proteins. Its hydrophobic character means that it generally requires treatment involving the physical separation of fat from water via a degreasing tank. The treatment generates significant volumes of fat to be regularly removed (usual frequency: every 3 months).

Degreasing tanks are designed to retain the fat, which is lighter than the water, when removing water from kitchens. The retention method involves the use of baffles to block the passage of fats or a series of small degreasing tanks.

Degreasing tanks call for frequent and expensive maintenance:
  • Regular emptying, approximately every 3 months;
  • Impromptu unblocking work;
  • Cleaning operations after overflows;
  • Odour control after nauseous emissions.
REALCO’s answer is a solution injection method based on environmental biotechnology.
It involves injecting a liquid product from the CPL range.
These are enzyme-bacteria based liquids formulated specifically for treating waste water high in organic residues. CPL range products contain a wide spectrum of enzymes (protease, lipase, amylase and cellulase) and a bacteria concentration (3,107 CFU / ml) formulated specifically for metabolisation of organic matter and in particular fatty matter.

Daily injection is recommended:


where? : ideally, in the evacuation pipes of dishwashers or scullery sinks.

when? : with the last discharge water (1 hour before stopping).

frequency? : each day of operation.

how? : programmable peristatic pump (requires a 220V electricity source nearby).

Comments:
We recommend starting the treatment with a previously drained, clean installation;
Mixing the crust 1 x / quarter will improve treatment effectiveness;
We do not recommend injection for water over 80°C;
We recommend avoiding the introduction of bactericidal products (disinfectants) at the same time as the product is injected;

Treatement of greases - LIPAMAX:

Pre-treating domestic and industrial waste water generates various by-products, of which one is fatty waste. In the majority of cases, the main outlet is land disposal. But looking at the new regulations, fats will no longer be authorised in waste burial centres.

REALCO has developed a process for treating fatty residues at the purification station itself. The process is based on a biological treatment involving hydrolysis and partial metabolisation of the fatty matter. It enables partial treatment of fats to make them more easily assimilable during downstream biological treatment in the purification station.

Hydrolysis and partial metabolisation take place in an aerobic reactor, situated between the primary treatment process and biological treatment in the purification station. The complex CPL-60- DP50 is injected for hydrolysis and partial metabolisation of the fatty matter and to encourage transfer between fatty matter and reagents.

Fatty matter that has been pre-treated using the CPL-DP complex modifies the metabolic properties of the activated sludge. The activated sludge effectively breaks down the pre-treated fats in the same way as with other organic substrates such as proteins or other simpler residues such as sugars.

The LIPAMAX process thereby allows assimilation of the fats by the station and is also recommended in tertiary de-nitrification and phosphate removal as an easily assimilable C source.

Treating of undersized or overloaded WWTP

Undersized or overloaded WWTP =
plant of which the purifying performance initially foreseen does no longer meet the present requirements.

Objective : to restore an optimal purifying efficiency

Problems : an increase of the polluting load, an increase of the “equivalent habitant” (EH), a raise in maintenance costs, draining standards that are no longer acceptable,…

The enzyme offers THE solution

The enzyme is a protein which decomposes organic macromolecules into smaller components, making them water-soluble and, hence, easier to be assimilated by the bacteria.

Action enzymes

=> The enzymatic products (CPL range) accelerate and optimize the hydrolysis phase: this makes the absorption by the bacteria easier and improves the quality of the purification.

Products

CPL 50
CPL50

The enzymes allow you to skip the limiting stage, which the hydrolysis actually is, whereas the bacteria improve the metabolism output.

The CPL 50 will enhance the biology, thanks to the input of elements
that can be easily and directly assimilated.
CPL 60

This complex of enzymes and of bacteria is designed for the processing of fatty waste.
DP 50

The DP 50 is an agent which is highly recommended for improving the metabolism performance when processing organic material. It will enhance the exchanges between substrates and purifying bacteria.
