Water Purification System
Overview
Nearly 4 M people die each year from water related diseases One in eight people lack access to clean water supplies Need for water sanitation has become a global crisis In the Philippines, access to clean and safe drinking water remains a problem, particularly in the rural areas
Common waterborne diseases
diarrhea/dysentery cholera typhoid fever infectious hepatitis vomiting
Conventional Water Treatment Process
Sedimentation Filtration Disinfection Safer Water Storage
Safe Water Storage
Ceramic water filtration
Popular method of treating contaminated water System consists of a porous ceramics and a receptacle/container Water is poured into the upper portion of the receptacle or directly into the porous ceramics, where gravity pulls the water through the pores in the ceramics and into the lower portion of the receptacle/container where the filtered water is safely stored Several types
Disk
Candle Pot Cylindrical

Micro-organism (bacteria) and particulates are common contaminants present in tap and ground waters Contaminants cause the spread of water-borne diseases Micro-filtration, e.g., ceramic-based micro-filters (0.1 50 um) is a proven technique to take out such contaminants ITDI-DOST can provide an innovative solution in ceramic filtration to take out microbial/particulate contaminants in drinking water for use in household level
Develop pot type ceramic filter with nano antimicrobial coating Utilizes indigenous raw materials: red clay
Ceramic Filter Model
Ceramic Pot Filter 6L capacity
Ceramic Pot Filter 1.5L capacity
Filter Assembly
Operation
Water from source is poured into the ceramic pot. The water slowly passes through the pores and is collected in the lower container. The filtered water is stored in the container until needed, protecting it from contamination. The user simple opens the tap at the base of the container when they need water.

Micro-Filtration Performance Test
Type of Test Microbiological Quality (raw water vs filtered water) Test Process:
Ceramic Pot Filters were distributed among selected households in the NHA housing in Muntinlupa. Water from NHA deep well system was used as test sample and fed into the ceramic pot filters Filtered water samples were gathered from subject households and tested for microbial quality alongside unfiltered water from the same deep well system

Comments/Feedbacks
Medyo mabigat Nagagamit sa pagluluto Kailangan maingat sa paglinis Masarap and lasa ng tubig Maayos walang problema Nakatipid sa pagbili ng mineral water Sa unang pagagamit, may amoy ang tubig

Comments/Feedbacks
At Calaanan 1, the filter was used by at least 25 families All were happy and satisfied with the ITDI filter because they dont need to buy icewater or commercial clean cold water for drinking There was no reported/observed adverse effect on the health of the users At XU Ecoville Lumbia Transition Shelter, they only observed a clay-smell

Updates
WPS units were given to Project Malasakit for distribution to Mangyan households in Mindoro Oriental Inquiry from JCI Marikina Sapatos for distribution to Marikina households Philippine Army also requesting for said WPS units
Updates
Pottery producers in Region 3 send a letter expressing their interest to adopt the developed technology on ceramic water filtration system. MOA has been prepared for the training cum production Consultative meeting at Tanauan , Leyte with regards the establishment of a common service facilites for ceramic production including ceramic pot filter
Summary Features of WPS Easy to fabricate and operate Low investment Use of indigenous materials Pass the microbiological criteria set by PNS for drinking water
Recommendation
Improvement of design and set-up R&D on anti-microbial coating
