“…Water quality with pH 2.5 ~ 3.5 and salinity 0.25 ~ 0.35 mS/cm was found in the middle to the end of the channel. The efficiency of reclamation measures is determined based on water management balances, including maximum pollution coefficients estimation [8]. Instantaneous quality measurements confirmed this phenomenon in the primary channel (Table 1).…”

The reclamation process of acid sulphate soil of the Belanti II tidal irrigation scheme remains unfinished. During ebb tide, the upstream acidic drainage water retains and settles in the irrigation canals. During high tide, the acidic water flows back into some parts of the agricultural land and reduces rice productivity. The measured pH is about 2.5 ~ 3.5 and the measured electric conductivity is about 0,25 ~ 0,35 mS/cm. Sedimentation in the middle to the end of the primary, secondary, and collector canals and tidal pond at the upstream end of the primary canal, preventing the leaching process of sulfuric acid soil. Primary canal normalization as an alternative solution to increase the capability of acidity leaching is proposed. Leaching the acidic soil of Belanti II irrigated area of 3.976 ha requires 500 m3/ha/day of freshwater, equivalent to 1.998.000 m3/day. The one-dimensional HEC RAS mathematical model is used to evaluate the hydraulics performance to support the leaching process. The hydraulic analysis was carried out using two tidal cycles on the existing channel and the normalized channel. Channel normalization has succeeded in reducing the water supply deficit to support the leaching process from 39% to 9%.

The methods of gypsum application in degraded soils to increase and restore saline and degraded soils, to grow vegetables and fruits in the arid zone are considered in the paper. The issues of soil alkalinity reduction to increase soil fertility with the use of a new biomeliorant at standard of ST RK 2208-2012 containing phosphogypsum, calcium, sulfur and cattle manure with the addition of crushed camel thorn were studied. According to calculations this meliorant application reduces the loss of nitrogen and organic matter by 40%,, which being a highly effective fertilizer that improves the physico-chemical and biological properties of the soil, which contributes to an increase in crop yields. Field studies have shown that the joint anaerobic fermentation of phosphogypsum and manure, camel thorn led to intensive aggregation and the creation of favorable conditions of the soil structure for the crops. The results showed that the biomeliorant application into the soil led to a noticeable improvement in its structure, increases alkalinity, soils become more fertile and crop yields increase.

The article presents research on demulsifiers for oil dehydration in order to increase the conservation of water resources by introducing an additional source. The laboratory experimental works on selection of highly effective demulsifier were carried out. The application of water-saving technology which provided the necessary technological and economic effect was proposed. The analysis of laboratory researches on improvement of the method of dehydration of high-viscosity watered oil showed that under optimally selected conditions, namely: concentration of 75 g/t, temperature of 70 degrees and long settling time, the most effective demulsifier from all the reagents used in the tests was the reagent number 2 which showed the lowest residual water content and satisfied the final criteria both in economic terms and in quality of separation of water from oil without changing its initial structure. The water extraction according to the improved oil dehydration technology increased from 10% to 60%.
