Necessary for people

In recent years, tuna fishing and catching in Phu Yen has constantly developed. Each fishing trip usually lasts 15 to 50 days. However, the amount of water brought for each voyage is very limited, affecting the fishing and living activities of fishermen. To solve this problem, Tecomen Joint Stock Company (Hanoi) cooperates with the Provincial Fishery Association to put the seawater purifier pure fresh water to test run on the fishing vessel PY90612TS of fishermen Le Tan Hong in Phu Dong ward (Tuy Hoa City). This is the first fishing vessel in the province with seawater filter installed.

 

Mr. Nguyen Tien Cuong, Director of PURASTAR seawater filter project of Tecomen Joint Stock Company, said: PURASTAR's water filter system installed on offshore fishing vessels of fishermen Le Tan Hong with capacity Filter 80 to 100 liters / hour. This project is commissioned for offshore fishing vessels in 4 provinces of Quang Ngai, Binh Dinh, Phu Yen and Khanh Hoa, one province each. To date, the installation of seawater filters for the four vessels has been completed, of which four 

ships are currently operating in the sea and also ships entering the shore. The trial operation was aimed at finding out the weaknesses of the machine for the company to overcome and also introduced seawater filter products to the fishermen.

 

The ship PY90612TS departed on August 1, after 28 days of operation in the sea, this fishing vessel has now landed. Crew member Dinh Van Dung in Phu Thanh ward (Tuy Hoa city) went on a fishing boat PY90612TS, said: "The previous trips, each trip must bring about 150 fresh water cans, 20 liter plastic cans, the number of water cans has occupied a relatively large area on the ship. We had only a small amount of fresh water to prevent any problem with the machine. However, through this voyage, the water purifier works very well, not only for drinking water but also for crew members on the boat to bathe comfortably. And the owner of PY90612TS fishing boat Le Tan Hong said: "Thanks to the reduction of the weight of fresh water to bring (about 5 tons), this voyage, my fishing boat when going offshore runs faster, it used to take 3 days before now 2 and a half days have reached the fishing ground. After 28 days of operation, the cost of running fuel drops to about 3.5 million and fresh water is used comfortably. However, I have a suggestion to design this water purifier a little more compact ... ”.

Advanced technology

 

 According to Tecomen Joint Stock Company, average seawater has a salinity of about 3.5%, meaning that for every liter of seawater contains about 35g of salt, in addition to other minerals. Currently, there are some technologies to treat seawater potable fresh water in the world without boiling, in which RO technology (reverse osmosis) is applied more because of 

reasonable cost. RO technology of sea water technology recognized by Tecomen has the ability to completely remove impurities that are harmful to human health, it creates a pure freshwater. This seawater filter is based on RO reverse osmosis mechanism with specially designed parts to suit harsh working conditions in marine environments. Materials in contact with sea water are made composite, 316 stainless steel, copper alloy, rubber, piping system, connecting accessories must be made of durable materials, withstand drag, compression, bending according to standard properties. design math. Tecomen's seawater freshwater filter is widely used on ships, especially long-time fishing vessels, at rigs, hotel restaurants on the island or on the coast.

 

Mr. Nguyen Tien Cuong added: Seawater filter PURASTAR is a product of Tecomen manufactured and assembled domestically with the cost of about 95 million VND. After this trial, the company will hold a workshop and will acknowledge comments coastal fishermen and fishermen four fishing vessels with this seawater filter installed to improve it. The company has agreed to allow Le Tan Hong's PY90612TS fishing vessel to continue the second test and the company will donate the water filter to Phu Yen fishermen.
