The ecology of high-water plants such as pistachio, euchronia, azolla forms the basis for improving biological wastewater treatment technology. For the first time in the Andizhan region of the Republic of Uzbekistan, it was found that high-altitude algae can be used by the method of biological treatment of municipal wastewater. the results of the study, we used biological treatment of high-water plant species such as pistia (Pistia stratiotes), Euchornia crassipes Solms, azolla (Azolla coroliniana Willd), with the observations of the dynamics of rapid growth and development at high concentrations. We developed a Pistia stratiotes, which is scientifically grounded in improvement, and was recommended for reproduction under laboratory conditions.

The article reports on the research results of wastewaters biological treatment at Novokuibyshevsk oil refining plant using the technology of nitrification - denitrification. The paper reveals the possibility of meeting modern requirements for treated water quality by nitrogen compounds while treating industrial wastewater without mixing it with municipal wastewater. Necessary dependencies and technological parameters for choosing the mode of experimental and production use of treatment structures by one-stage scheme with nitrification-denitrification are given.

Malaysia is currently one of the biggest producers and exporters of palm oil and palm oil products. In the growth of palm oil industry in Malaysia, quality of the refined oil is a major concern where off-specification products will be rejected thus causing a great loss in profit. In this paper, predictive modeling of refined palm oil quality in one palm oil refining plant in Malaysia is proposed for online quality monitoring purposes. The color of the crude oil, Free Fatty acid (FFA) content, bleaching earth dosage, citric acid dosage, activated carbon dosage, deodorizer pressure and deodorizer temperature were studied in this paper. The industrial palm oil refinery data were used as input and output to the Artificial Neural Network (ANN) model. Various trials were examined for training all three ANN models using number of nodes in the hidden layer varying from 10 to 25. All three models were trained and tested reasonably well to predict FFA content, red and yellow color quality of the refined palm oil efficiently with small error. Therefore, the models can be further implemented in palm oil refinery plant as online prediction system.

Fatty Acid Distillate

A study on factors affecting biodiesel quality of agricultural by-products, namely palm oil derived using palm fatty acid distillate (PFAD), collected from the Oleen Palm Oil industrial refining plant. This PFAD showed free fatty acid content and a saponification value of 88.4 % and 204 mg KOH/g, respectively. An acid catalyst was successfully used to produce biodiesel in the esterification reaction, and a 97.11% conversion to biodiesel based on the European Standard EN 14214:2003 was achieved under the conditions (PFAD to methanol molar ratio 1:3.71 with 1.834 % H2SO4 catalyzed at 121 °C for 15 minutes). Overall, this novel process achieved highly enhanced FAME (95.82% to 97.31%) with a significantly increased reaction time (10 to 30 minutes) and catalyst requirements (1.834 % H2SO4).

This article presents the results of a comparative study of the method of biological treatment using aquatic plants and algae to improve the technology of treatment of domestic and municipal wastewater treatment plants formed in urban areas. According to test results, 5 species of aquatic plants and 2 strains of algae tested, pistachio and eucalyptus species, and strains of Chlorella vulgaris UA-1-6 were found to be resistant to domestic wastewater. This water plant laripistiya and eichorniya species grow well in different wastewater concentrations (25%, 50%, 100%) in the 100%. Both water treatment stations have a high yield and treatment levels. It was observed that it reached 90% at the "Binokor" water treatment station and the water treatment station "Salar" - 82-86%. This is because the amount of harmful substances in the wastewater of the "Salar" water treatment station is 5 times higher than the number of pollutants in the water treatment station "Binokor". It should be noted that the results of wastewater treatment works at 2 water treatment plants showed that the type of pistachio plant is more resistant to wastewater than the type of eucalyptus, and the level of treatment is also high. Therefore, in the experiment at the "Salar" water treatment station, we found it necessary to use the pistachio water plant itself. At this wastewater treatment station, wastewater treatment reached an average of 84%, and to increase the treatment efficiency, we grew Chlorella vulgaris in the second treatment stage and found that the treatment efficiency was 90-92%. This means that the treatment of wastewater in each treatment station requires the development of biological treatment technology following it.
