“…On the other hand, several ice slurry research pioneers have reported the variation of pressure drop as a function of ice fraction, flow velocity, flow direction (upward, downward, and horizontal), additives at different initial concentrations, and particle diameters based on experimental data. ,,− Additionally, extensive experiments have measured the pressure drops of ice slurry flows in typical components of pipeline systems including a T-junction, , pipe tees, flow dividers, a helically coiled pipe, pipe sudden contractions, pipe sudden expansions, pumps, and valves Figure a and b presents the pressure drops across a heat exchanger (with an equivalent hydraulic diameter of 24 mm) measured in experiments where ice slurries with various ice fractions flow at different speeds .…”

It has been established that treated water can be easily impacted when delivered through drinking water distribution systems (DWDS), with issues such as discoloration, metal ion release, and bacterial regrowth. As part of good practice, water companies should take reasonable steps to prevent contamination from DWDS. Because traditional maintenance strategies have limitations, ice pigging can be employed as a powerful pipeline cleaning technique with the advantages of high cleaning efficiency, environmentally friendliness, not sticking, and cost effectiveness in some scenarios. This study aims to provide a review of the state-of-the-art techniques of ice pigging for the water supply industry. After providing the mechanism of ice pigging, the generation and storage of ice slurries and ice fraction measurement were investigated. The critical aspects during the ice pigging process concerning the flow pattern, pressure drop, and survival distance of ice slurries were also discussed. In addition, this critical review integrated scattered knowledge on engineering design to improve the performance of ice pigging. Three important factors in practical engineering include ice slurry flow velocity, ice fraction, and ice pig length. Finally, informed by in-depth analysis of suitable applications and underlying mechanisms, ice pigging is expected to further enhance fouling removal capacity and enable better water quality, reduced service interruptions, and have fewer customer complaints.

Newtonian and non-Newtonian fluids are commonly transported with the piping system, but non-Newtonian fluids with particle-laden are more complicated to be transported due to various factors. A deposition is one of the problems that must be investigated due to affecting flow efficiency. The purpose of this study is to investigate the performance of 3-lobes spiral pipe in relationship with particles effect. The working fluid used had several variations of concentration weight (i.e. Cw 20%, 30% and 40%). Test pipes used had 1550 mm of length which consisted of a spiral pipe with P/Di=7 and a circular pipe with an inner diameter of 25.4 mm; both of the pipes were used to investigate the particles effect where the circular pipe for examining rheological of the working fluid. Slurry particles sized 1-5 μm in this study was obtained from the mud eruption at Semau Island, Kupang-Indonesia. By comparing both working fluids, the critical velocity observed in the spiral pipe was not as high as observed in the circular pipe, and thus the spiral pipe is more efficient to be used in slurry transportation from mud eruption area.

“…Several previous studies related to piping systems have been carried out in conjunction with the impact on environmental losses and energy efficiency (Senapati et al, 2013;Yanuar et al, 2018). The particle-laden fluid flow transport characteristics of solid water mixtures in piping systems need to be thoroughly understood so that it can be used to solve piping application problems.…”

The use of piping systems for fluid transportation is increasing because it is considered the most effective method. Newtonian and non-Newtonian fluid flows are suitable for piping systems, and non-Newtonian, particle-laden fluids are more complex due to various factors. Deposition is one of the problems that must continue to be investigated because of the effects of flow efficiency. The purpose of this study was to investigate the performance of the three-lobe spiral pipe effect. Working fluids in several variations of concentration weight (Cw 20%, 30%, and 40%) were used. Test pipe with a length of 1550 mm and consisting of spiral pipe P/Di = 7 and a circular pipe with an inner diameter of 25.4 mm were used. The circular pipe was used to investigate the rheological workings of fluid. Both pipes were used to investigate the particle effects. Using scanning electron microscopy, 1-μm to 5-μm slurry particles were obtained from the mud eruption source at Semau Island, Kupang, Indonesia. The critical velocity value of the spiral pipe was lower than the circular pipe, so the spiral pipe is highly effective for slurry transportation.
