The specific heat of aqueous graphene+Al 2 O 3 (1:1) hybrid nanofluid was measured using the cooling method. The influence of nanoparticle mass fraction and temperature on the specific heat capacity of the hybrid nanofluids was investigated, the specific heat of the hybrid nanofluid was compared with that of aqueous graphene oxide nanofluid and Al 2 O 3 nanofluid. A fitted formula of the specific heat of the hybrid nanofluid was proposed based on the experimental data. It indicates that the specific heat reduction ratio increases with increase of nanoparticle fraction; the maximum reduction ratio is 7% at 0.15wt% at 20 °C. The mass fraction of nanoparticle affects the specific heat of hybrid nanofluid more significantly at lower temperature. Temperature impacts the specific heat more distinctly than the nanoparticle fraction. The specific heat increases with temperature and the maximum specific heat reduction ratio of the hybrid nanofluid diminishes from 7 % at 20 °C to 2% at 70 °C at the mass fraction of 0.05%.

“…Selain itu mutu ikan sangat dipengaruhi oleh proses penangkapan yang berhubungan langsung dengan cara ikan mati. Kauffeld (2019) menjelaskan bahwa teknologi slurry ice pertama kali dipatenkan pada awal 1930, selanjutnya dikembangkan dalam bentuk aliran bubur es sebagai pendingin pada 1966, dan baru pada tahun 1985 benar-benar dibangun dan diteliti sistem bubur es. Dalam perkembangannya, Liu et al (2019) menjelaskan di antara 5 metode produksi bubur es, metoda scrapedsurface paling berkembang secara teknologi dan paling banyak digunakan oleh masyarakat.…”

Rekayasa terhadap evaporator, kondensor, dan sistem kontrol elektronik telah dilakukan untuk menghasilkan inovasi sebuah unit slurry ice machine/mesin pembuat bubur es (MPBE) yang dioperasikan dengan tenaga listrik 3 phase. Penelitian ini bertujuan untuk menghasilkan mesin pembuatan bubur es yang ramah lingkungan. Metode pembuatan dilakukan dengan menggunakan desain yang dibuat oleh PT Hikari Solusino Sukses dengan kapasitas masing-masing 0,5 dan 1,5 ton/hari . Hasil menunjukkan bahwa MPBE dapat mulai memproduksi bubur es sekitar 2 menit dengan kapasitas produksi 1.500 kg bubur es dalam 24 jam. Untuk memenuhi kebutuhan konsumen telah diproduksi unit MPBE berkapasitas 1.500 kg/24 jam yang dioperasikan dengan motor berbahan bakar solar dan berkapasitas 500 kg/24 jam yang dioperasikan dengan motor berbahan bakar bensin. Dibandingkan dengan unit prototipe MPBE yang telah dibuat dan unit yang dijual di pasar internasional, inovasi unit MPBE ini dapat memproduksi bubur es lebih cepat, yaitu 2 menit berbanding 20-30 menit, serta fraksi bubur es yang tinggi, hingga 90% dibandingkan 30-40%. Berdasarkan nilai lebih pada kualitas bubur es yang diproduksi, variasi pengoperasian menggunakan motor penggerak berbahan bakar bensin dan solar, serta dukungan ekosistem manufaktur di Indonesia, inovasi MPBE ini diyakini dapat diproduksi secara komersial karena harga dan kualitasnya yang kompetitif.

“…Recently, an innovative and environmentally friendly cleaning method, ice pigging, has been introduced and employed . This method involves pumping a saline ice slurry as a viable semisolid pig into the water supply pipe via a hydrant, air valve, or a 2-in fitting and using primary pressure to propel the pig through the pipe and out of the system via another downstream hydrant/fitting or upstream air valve .…”

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.
