SYNOPSIS

Understanding of the raw water source characteristic is the key to sustaining consistent desirable water quality for it subsequent usage. Running jar test, evaluate the various effect of coagulant, particularly the impact of pH, and flocculant dosage for effective and economical application is the first step. With the predetermine dosage from jar test, the actual application involving understanding the characteristic of the clarification system and its operation, dosing equipment, dosing points and observation of after effect for dosage adjustment.

Meanwhile, the objective of boiler water treatment is to prevent corrosion, scaling and carryover which could impact the boiler operation through tube failure, turbine problem and other related issues. Each of the aspect will be dealt with through mechanically and chemically. Whereby through typically operation unit in the food industry such as deaerator and softener, the undesirable chemical element particularly oxygen, hardness and iron for boiler water treatment can be reduced to its lowest possible theoretical figure. The residue of the element can then be controlled chemically. The control and maintaining of key boiler water parameters are important to ensure the boiler water treatment achieving its purposes.

Mr. Yan Long Yeow

work as a Senior Technical Service Manager for Drew Ameroid which mainly provides chemical treatment services for boiler, cooling, raw water, waste water, polymers and processing aids. He graduated from University of Wisconsin (USA)in engineering with a B.SC and M. SC in 1990 and 1991 respectively.

He worked as project engineer for a sewage treatment company from 1992-1994 which mainly dealing with design, built, construct and install sewage treatment plant. He then join Drew Ameroid as a water treatment engineer and since then with the company. He had completed his advanced technical training in head quarter in New Jersey, USA in1998. He has more than 26 years of field working experience for chemical treatment application in varies industries such as palm oil industry, biomass boiler, oil and gas industry, oleo chemicals plant, palm oil refinery, power plant, paper industry, food and beverage industry and other related industries. His scope of responsibility is to provide technical support and to assist in trouble shooting and optimization of chemical treatment application. He also represents Drew Ameroid to conduct boiler water treatment for MPOB, and regularly conducts refresh training for palm oil mills/refinery in the boiler, cooling and raw water and waste treatment aspect.
