This mill‘s POME system is land disposal. The treated POME normally having a pH of 8 and BOD below 1,000 is transfer via a centrifugal pump in 6in HDPE pipes for a distance of 2 to 3 km for disposal in their estate. Over 4-5years, the flow rate of 60m3/Hr has dropped drastically and upon checking the pipes, found excessive crystallisation in the 6in HDPE pipes reducing the effective diameter to less than 6in. The pipe surface became very rough. This has grossly worsen the piping system curve resulting in lower Flowrate. I am seeking member’s advice and help: 1. How to effectively clean these pipes to restore back its original diameter? 2. How to prevent or minimise the formation or built-up of this struvite crystallisation? 3. Is replacement of the pipes the ONLY solution? All advice and comments would be highly appreciated. Thank you.

Dear members, can anyone help me with any effective method to remove these struvites. Over 6 years, the effective diameter is reduced from 400mm to about 100mm. If there is no cost effective method of removal, we need to replace the whole length of the pipes. Are we doing the right thing? Members’ help urgently needed. Thanks

There is an interesting and controversial news posted in our News column on “ Malaysian oil palm associations call for govt to postpone revising minimum wage “ (Palm Oil Millers Association is included) in which Mr. Tan CS raised a few rather interesting but very constructive comments. Below are his comments: Regarding to appealing for revising minimum wages, I have different opinions, 1) As rightly pointed out, it will increase the production cost. I am of the opinion that the industry associations should urged government to revise the structure of “windfall tax” such as it’s threshold level and rate of taxes. Please bear in mind that windfall tax was introduced in year 2000, the threshold level then was RM 2,000 against the national average production cost of less than RM 1,000 OR national average profit margin of more than than 100 %. 2) Windfall tax is solely determined by CPO price and ignored other factors such as immature estates. 3) Appeal to government for more research and development for mechanisation of various estate operations because of rising labour costs. 4) Plantation players also should make use of revising minimum wages to their advantage to attract more local into the industry. 5) Palm oil industry is one of the very few industries subjected to windfall tax and therefore should be amongst the last for appealing delay in it’s implementation. What do our other members think?

Mill Engineers are doing a professional engineering job in Palm oil industry. They should be rightfully be eligible to obtain and be accredited Professional Engineer (PE) with the title of Ingenieur, Ir. However, it is strange to find that there are so few palm oil mill engineers in Malaysia been accredited with PE. Why? Are they not interested? Can we share some discussions from all PalmIngenieurs in this community?

(Posted on behalf of Prakash Baskaran) The kernel tray dryer design by Mr Wong Pong Meng was a good and efficient dryer which need to be brought back to the industry with new upgrade and for the improvement with new ideas and ingenuity. Can members share your idea and comments on this? Thank you.

What is the function of the orifice fitted at your main steam stop valve outlet? Does this orifice effect our fuel balance and boiler efficiency? Note: This question is posted on behalf of our PalmIngenieurs Prakash Baskaran.
