Abstract
Biofilms are deposits that form naturally and spontaneously in drinking water distribution systems. According to the invention, cade oil is incorporated as a bioactive substance for partially replacing the lubrication component in the classical formulation of the tube. This natural oil is known for its antibiotic effects and other health-related beneficial effects. The effect thereof has been studied by incorporating same into the formulation of the tubes of pipes formed by extrusion methods.

DESCRIPTION DESCRIPTION
Il s’agit de l'intégration de l'huile de cade (Katran) dans la formule du tube PVC. Cette huile est dotée d'une activité antibactérienne, elle présente une stabilité thermique intéressante et connue pour ses effets bénéfiques pour la santé. This is the integration of the cade oil (Katran) in the formula of the PVC tube. This oil is endowed with an antibacterial activity, it presents an interesting thermal stability and known for its beneficial effects for the health.
On s'est orienté vers la composante de lubrification, étant donnée tout d'abord le lien étroit avec le phénomène du collage et aussi le fait qu'au niveau de la formule du tube ces derniers migrent naturellement vers la surface. Nous avons étudié la formulation suivante : résine PVC 90% ; charges minérales 7% ; stabilisants 2%, Ti02 0,45%, noir de carbone 0,05% ; lubrifiant 0,45%, huile de cade 0,05% et vérifier les effets sur la formation des biofilms dans le nouveau tube fabriqué élaboré par procédé d’extrusion.
CONNAISSANCE SUR LE MARCHE, LA CONCURRENCE ET AVANTAGE The lubrication component has been oriented, being first of all the close link with the phenomenon of sticking and also the fact that at the level of the tube's formula these latter naturally migrate towards the surface. We studied the following formulation: 90% PVC resin; mineral charges 7%; 2% stabilizers, 0.45% TiO 2, 0.05% carbon black; 0.45% lubricant, 0.05% cade oil and check the effects on the formation of biofilms in the new tube manufactured by extrusion process. KNOWLEDGE ON THE MARKET, COMPETITION AND ADVANTAGE
ECONOMIQUE DE L'INVENTION ECONOMIC OF THE INVENTION
On connaît au Maroc, la commercialisation de la fameuse poterie avec des motifs faits en huile de cade. L’utilisation de cette huile rentre dans la culture du citoyen marocain, elle est également souvent utilisée en cas d'affections de la peau, elle rentre dans la composition de plusieurs shampooings et de savons médicamenteux. Le présent travail propose alors une formulation nouvelle du tube PVC rigide intégrant l’huile de cade à raison de 0,05%. We know in Morocco, the marketing of the famous pottery with motifs made of cade oil. The use of this oil is part of the culture of the Moroccan citizen, it is also often used in cases of skin conditions, it is part of the composition of several shampoos and medicinal soaps. The present work then proposes a new formulation of the rigid PVC tube incorporating the cade oil at the rate of 0.05%.
Cette invention propose une nouvelle formule pour la fabrication des tubes PVC utilisés dans l'adduction d'eau, la dégradation de sa qualité au cours de son transport dans les réseaux, en raison notamment d'un détachement de bactéries éventuellement présentes au sein de biofilms, culpabilise les traiteurs et distributeurs d'eau malgré les efforts fournies pour produire une eau de bonne qualité. Le Maroc est bien connu par sa fameuse poterie à boire avec des motifs noirs dessinés dessus fait de katran (huile de cade). This invention proposes a new formula for the manufacture of PVC tubes used in the water supply, the degradation of its quality during its transport in the networks, due in particular to detachment of bacteria possibly present within biofilms , makes the caterers and water distributors feel guilty despite the efforts they have made to produce water of good quality. Morocco is well known for its famous pottery to drink with black patterns drawn on it made of katran (cade oil).
Concevoir des canalisations d'adduction d'eau potable intégrant l'huile de cade devrait permettre en plus : Designing drinking water supply pipelines incorporating cade oil should also allow:
• De trouver des moyens de lutte pour limiter l’adhésion microbienne et par conséquent optimiser l’hygiène des surfaces dans le domaine de la distribution de l'eau potable. • To find ways of controlling microbial adhesion and therefore optimize surface hygiene in the field of drinking water distribution.
• La maîtrise de la qualité microbiologique de l'eau potable devrait donc avoir des retombées positives certaines sur la conformité de cette eau et sur la protection de la santé publique. • The control of the microbiological quality of drinking water should therefore have a definite positive impact on the compliance of this water and on the protection of public health.
• L'invention de nouveaux matériaux et la définition de nouveaux procédés pour la fabrication d'une nouvelle gamme de canalisations permettant
d'empêcher la formation des biofilms : problématique d'ordre santé publique. La prévention contre la formation de biofilms permettra le limiter les pratiques curatives tel que la de rénovation onéreuse des réseaux de distribution d'eau potable • The invention of new materials and the definition of new processes for the manufacture of a new range of pipes to prevent the formation of biofilms: public health problem. Prevention against the formation of biofilms will limit curative practices such as the expensive renovation of drinking water distribution networks
La présence de biofilms dans l'eau potable doit être éliminé selon une stratégie plutôt « préventive », les stratégies curatives tel que la réhabilitation des réseaux semble être très coûteuse, La conception d'un matériau antiadhésif dont le coût doit être raisonnable pour la fabrication de conduites de canalisation, l’huile est disponible dans le marché, et connaîtra une nouvelle valorisation. Les solutions proposées pourront être généralisés et appliquées dans les ateliers, les matériaux des équipements et les emballages d'agroalimentaires. The presence of biofilms in drinking water must be eliminated according to a rather "preventive" strategy, curative strategies such as the rehabilitation of networks seems to be very expensive, The design of a non-stick material whose cost must be reasonable for manufacturing pipeline, the oil is available in the market, and will enjoy a new valuation. The proposed solutions can be generalized and applied in workshops, equipment materials and agri-food packaging.
