Introduction and Background
INTRODUCTION
In Malaysia, river water - the main source of
water supply
Drinking water - treated by the water treatment
plant.
Aluminum Sulfate (Alum) - used in water
treatment widely.
Negative Impact of Alum - Parkinson and
Alzheimer’s disease and produce hazardous
toxics waste due to Aluminum sludge
Need for alternative way to treat water

Project Description
PROJECT DESCRIPTION
Water Treatment using
fungi based polymer – no
chemicals
Objectives:
1.
To transfer knowledge on application of biopolymer (based on AFlavus) to treat river
water.
2.
To create awareness, and promote adoption of, green and environmentally-friendly
products
3.
To show the superior efficacy of UPM’s A Flavus product in providing high water quality.
BENEFIT:
1.
Easy to produce locally
2.
Low cost process
3.
100% natural - No toxic sludge
4.
Able to treat pond and river water
Methodology:
1.
Design mini plant for treating water
2.
Training program with Industry
3.
Evaluation program on effectiveness
of biopolymer to treat water

Project Activities
PROJECT ACTIVITIES - MILESTONE
A site visit has been carried out by PMT Group staff to identified
the most suitable location to locate the biopolymer and pilot
plant on 13th and 15th December 2011.
A design group meeting was carried out between UPM – PMT
Group in the months February 2012 and April 2012.
Water sampling has been carried out on 16th January 2012 and 8th
February 2012 at 5 locations. The samples for all locations had been
sent to the laboratory for analysis.
Site Visit has been carried out on 31st January 2012 at Puncak
Niaga Water Treatment Plant of Sg. Langat. A view inside the
water treatment pilot plant showing the rapid mixing tank,
coagulation and the floculation tank

Impacts to Industry/ Community
IMPACTS TO INDUSTRY/ COMMUNITY
The industrial partner (PMT)
gets transfer of tech - new
method of treating water.
Company’s
adoption
of
green product in their
business and services.
The product has created
value added image to
company –more competitive
and open new venture.
The strong ties between
UPM-Industry
enabled
partnership
with
Local
Authorities (MPSJ) to use the
new product.
Launching Serdang Green Town
KTP project at public display

Impacts to Graduate Training
IMPACTS TO GRADUATE TRAINING
2 postgraduate students are involved in the real
world and current issues related with water
treatment (1 PHD and I Master).
The application of technology will be made in the
practical sessions, sharing experience in design ,
construction and operation of water treatment
plant
A demo unit pilot plant is used as lifelong
learning and engagement with users of
technology.
