A technological investigation was carried out over a period of 2 years to evaluate surface water treatment technology. The study was performed in Poland, in three stages. From November 2011 to July 2012, for the first stage, flow tests with a capacity of 0.1–1.5 m3/h were performed simultaneously in three types of technical installations differing by coagulation modules. The outcome of the first stage was the choice of the technology for further investigation. The second stage was performed between September 2012 and March 2013 on a full-scale water treatment plant. Three large technical installations, operated in parallel, were analysed: coagulation with sludge flotation, micro-sand ballasted coagulation with sedimentation, coagulation with sedimentation and sludge recirculation. The capacity of the installations ranged from 10 to 40 m3/h. The third stage was also performed in a full-scale water treatment plant and was aimed at optimising the selected technology. This article presents the results of the second stage of the full-scale investigation. The critical treatment process, for the analysed water, was the coagulation in an acidic environment (6.5 < pH < 7.0) carried out in a system with rapid mixing, a flocculation chamber, preliminary separation of coagulation products, and removal of residual suspended solids through filtration.

Primary water source of people in  fisherman area in Kabupaten Pasir, Kalimantan Timur for daily water need generally is from  surface water  or deep well. Surface water is affected by water tide of sea water, so that almost all the time  in a year the water quality is salty or brakish. Beside high salt concentration, deep well quality  is also worst.  This is caused by poor environmental sanitation of fisherman community.  Rainy water use as water source alternative in problem solving for limited water drinking only provide in rainy season. Other alternative, people must find from other area where is far from their house or buy water with expensive price. To solve this critical problem is required the application of suitable  water treatment technology. This water treatment  technology must produce drinking water that meet technical standard and　 the technology is applicable, easy and cheap in operation and maintenance because it is hoped that community in that area can manage, operate  and maintenance. Kata Kunci : Penduduk nelayan, penyediaan air bersih, teknologi pengolahan air bersih.
