North Bandung Cattle Ranching Cooperative (KPSBU) Lembang is a single primary business cooperative that acts as a distributor of fresh milk produced by cows owned by its member breeders. The distribution of fresh milk from farmers to cooperatives is a movement of material flow from suppliers to factories known as inbound logistics. This study was aimed to analyze the inbound logistics performance of fresh milk at KPSBU Lembang, its value added for the farmer, as well as the nutritional and microbiological quality. SCOR-AHP was used to analyse inbound logistics performance. The Hayami method was used to analyse value added of fresh milk for the farmer. Fresh milk quality indicators were total solid, protein, fat, pH, specific gravity and total plate count. Obtained data were analyzed descriptively. The results showed that fresh milk inbound logistics performance at KPSBU Lembang was 92.77% (above average). The added value obtained by breeders based on concentrate input amounted to Rp. 8.464 per cow with a value-added ratio of 73.83%. The quality of fresh milk during inbound logistics fulfilled national standard SNI 3141.1.2011.

Alkaline-surfactant-polymer (ASP) flooding technology is used to maximize crude oil recovery. However, the extensive use of alkaline materials makes it difficult to treat the water used. Here, an improved multi-zone anaerobic baffled reactor (ABR) using FeSO4 as electron acceptor was employed to treat the wastewater from ASP flooding technology, and the effects on major pollutants (hydrolyzed polyacrylamide, petroleum substances, surfactants suspended solids) and associated parameters (chemical oxygen demand, viscosity) were evaluated. Gas chromatography-mass spectrometry (GC-MS) was used to follow the degradation and evolution of organic compounds while high-throughput DNA sequencing was used to determine the bacterial diversity in the ABR. The results obtained after 90 d of operation showed decreases in all parameters measured and the highest mean removal rates were obtained for petroleum substances (98.8%) and suspended solids (77.0%). Amounts of petroleum substances in the ABR effluent could meet the requirements of a national standard for oilfield reinjection water. GC-MS analysis showed that a wide range of chemicals (e.g. aromatic hydrocarbons, esters, alcohols, ketones) could be sequentially removed from the influent by each zone of ABR. The high-throughput DNA sequencing showed that the bacteria Micropruina, Saccharibacteria and Synergistaceae were involved in the degradation of pollutants in the anaerobic and anoxic reaction zones, while Rhodobacteraceae and Aliihoeflea were the main functional microorganisms in the aerobic reaction zones. The results demonstrated that the improved ABR reactor had the potential for the treatment of wastewater from ASP flooding technology.

Abstract Water quality is the most important factor for consumers because it has a significant impact on their health. So, monitoring and controlling water quality is of particular significance in different human communities such as universities. In this study, the physicochemical parameters such as turbidity, electrical conductivity, hardness, alkalinity, calcium and magnesium ions, and heavy metals including lead, cadmium, nickel, arsenic, and chromium in drinking water were determined in nine Iranian universities. Then, the efficacy of several treatment methods was evaluated in the removal of heavy metal, including the boiling process in two stages: 5 minutes boiling and 5 hours boiling and filtration process. The results revealed that the physicochemical quality of drinking water in all universities was appropriate. Hardness levels in drinking water samples of all universities were higher than the WHO standards. However, this parameter was lower than the national standard of Iran (500 mg/l). Nevertheless, cadmium content was not detected in any samples, nickel content was below the permissible limit, and chromium content was below the permissible limit in all samples. However, its value was higher than the allowable limit in the university with a code of 6. Lead content was higher than the limit in samples with codes 3, 5-1, and 5-4, and arsenic content was higher than the limit in samples with codes 6, 1-1, 1-2, and 2. Water purification methods, including boiling and water purifier, were satisfactory and significantly reduced pollutants. According to the present study, it is suggested to check drinking water quality in universities randomly, and the 5-minute boiling method can be recommended as a cost-effective solution for water purification.

SiC was chosen as the foaming agent, and river bottom silt, waste oil sludge, paint bucket slag, and fly ash were used as raw materials, to prepare lightweight ceramsite without adding any chemical additives. The effects of SiC dosing and sintering temperature on various properties of the ceramsite were studied, and the pore-forming mechanism of the lightweight ceramsite was clarified by thermal analysis and X-ray diffraction analysis. The results showed that the single ceramsite compressive strength, water absorption, bulk density, and porosity of ceramsite sintered at 1180 °C with 1.0% SiC were 2.15 MPa, 2.02%, 490 kg/m3, and 23.85%, respectively. The major mineralogical compositions were quartz, fayalite, and kyanite, with small amounts of albite-low from 1140 to 1190 °C. Furthermore, the concentration of all tested heavy metals from ceramsite was lower than the maximum allowable concentration of the leaching solution specified in the Chinese national standard (GB 5085.3-2007), which reveals that this solid waste ceramsite will not cause secondary environmental pollution. The prepared ceramsite, exhibiting lower bulk density, high water absorption and porosity, and effective solidification of deleterious elements, can be used to prepare green lightweight aggregate concrete. Importantly, preparation of solid waste ceramsite is an effective way to dispose of hazardous wastes.

Abstract Geopolymer recycled aggregate concrete (GRAC) was prepared by replacing cement with geopolymer and natural aggregate with wast concrete. The effect of water-glass modules on mechanical properties of GRAC was studied. It was found that there are tow kind of binding structures in geopolymer hydration product: C-A-S-H and N-A-S-H, they both contribute to the strength of GRAC. The value of size conversion coefficient of current national standard is inapplicable for GRAC, the calculation method of which is given in this paper. Elasticity modulus and peak stress of GRAC is proportional to water-glass modulus, and peak strain is inversely proportional and its constitutive equation was established.
