Project Description

PROJECT DESCRIPTION

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.

Methodology:1. Design mini plant for treating water 2. Training program with Industry3. Evaluation program on effectiveness of biopolymer to treat water

Water Treatment using fungi based polymer – no

chemicals

BENEFIT:1. Easy to produce locally2. Low cost process3. 100% natural - No toxic sludge4. Able to treat pond and river water

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 GRADUATE TRAINING2 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 plantA demo unit pilot plant is used as lifelong learning and engagement with users of technology.
