Definitions

  • the invention relates to a method for Home & Commercial Water filtration with Self-Cleaning System that does not use power and the water which is to be purified and which contains organic and/or inorganic particles, will involve the water flow through a Filtration Apparatus with Polymers hollow fibre membrane media, producing permeate or filtrate water fit for a specific purpose.
  • the filtration apparatus consists of Polymers hollow Fibre membrane media enclosed in a capsule and the hollow fibres media are bundled together, forming a membrane module to allow direct water to pass through the hollow fibre for cross-flow filtration.
  • the membrane module had opened ends to allow self-cleaning and backwash for the membranes.
  • Figure 1 show a filtration Apparatus consist of Polymer hollow fibre membrane module enclosed either in Stainless or Polymer Housing for the purpose of Home and Commercial Water Filtration System with self-cleaning and backwash features.
  • the hollow fibre membranes are bundled together with a solidified plotting material cast around the ends of numerous membranes with both ends of the hollow fibres opened for (a) cross-flow filtration, (b) self-cleaning and backwash features and (c) hollow fibre membrane interconnection pipe for the Apparatus 2 nd Tap of the System.
  • the hollow Fibre membrane are made of polymer either in
  • PTFE Polytetrafluoroethylene
  • PVDF Polyvinylidene fluoride
  • PP Polypropylene
  • the Filtration Apparatus membrane media are polymer hollow fibre membrane with either pores sizes ranges from Micro, Ultra to Nano Filtration.
  • the Product Water (permeate or filtrate) are fit for a specific purpose (6) and available for discharge at Tap (7) of the filtration Apparatus. Option Discharge of Product Water are also available at two other locations (7a & 7b) within the Filtration Apparatus.
  • the condition(s) for the use of 2 nd tap (5a), when it is connected to a functional location where the use of water comes from the 2 nd tap (5a) is more for the purpose of general usage and cleaning, watering of plant etc.
  • the frequent usage of 2 nd tap (5a) will serves as a frequent self-cleaning and backwash of the hollow fibre membrane and will further significantly delay the fouling of membrane; prolonging the lifespan of the Filtration Apparatus used.
  • the water quality at the 2 nd tap (5a) may consist of some impurity from filtration residue, however, with constant and frequent usage (water discharge at the 2 nd tap) of the 2 nd tap, the concentration of such impurities will be diluted and negligible; i.e. quality of water at 2 nd tap will be almost identical to the original water at source.

Abstract

L'appareil de filtration selon l'invention utilise le principe du procédé de filtration à courants croisés qui a été modifié pour permettre l'auto-nettoyage et le rétrolavage en ligne de la membrane en fibres creuses d'une manière automatique ou manuelle, sans qu'il soit nécessaire d'utiliser de l'électricité et au moyen de la source d'eau. Lors d'une filtration à courants croisés, le déplacement tangentiel de la masse d'eau fluide à travers la membrane provoque le départ des particules piégées sur la surface du filtre du fait du frottement. Ceci signifie qu'un filtre à courants croisés peut être utilisé de manière continue à des charges en solides relativement élevées. Les autres bénéfices sont les suivants : 1. la vitesse globale de filtration de liquide est plus élevée car la formation d'un gâteau de filtration et l'encrassement de la membrane sont évités ; 2. la charge d'alimentation du procédé reste sous la forme d'une suspension mobile, qui est appropriée pour un traitement ultérieur ; 3. la teneur en solides de la suspension produite peut varier sur une vaste plage ; 4. Il est possible de fractionner les particules selon leur taille. La technologie de filtration à courants croisés sur membrane est largement utilisée dans l'industrie et, avec ladite modification consistant en un « auto-nettoyage et rétrolavage en ligne », le problème lié à l'encrassement de la membrane est grandement réduit et l'appareil de filtration d'eau domestique et commerciale fonctionne de manière optimale.
