Research and technology aspects in designing, developing and operating water monitoring system

The paper provides the data on global shortage of freshwater resources and requirements to control these resources. The information support of the management and control is based on gathering the information provided by system to monitor water bodies (MWB). Based on goals addressed by the management system the requirements are set forth to MWB, which, in turn, determine the system tasks and procedures to design it. The paper is addressing the composition of main stages in designing MWB.

Development potable water supply and disposal systems in townships and agricultural centers in kaliningrad region

The paper addresses the status of potable water supply and disposal systems in Kaliningrad region. Examples are provided on implementing joint projects involving local administrations and a number of domestic and foreign companies to supply potable water of required standard. Proposals issued by the Housing and Construction Ministry of Kaliningrad Region to stabilize the situation with water supply and sewerage in small townships and rural settlements are presented.

Eveloping a system to treat mine (pit) water

Тhe paper addresses some aspects in resolving an issue of treating mine (pit) water and formation water produced in Russian mining industry. The basic requirements to develop mine water treatment facilities are outlined. They comprise water treatment to required purity degree; low cost of treatment; availability of reagents to carry out treatment, and, if possible, the use local resources as well as potential to recover nonferrous metals from mine and formation water.

Sorbtion processes to treat oil contaminated water

The potential of using sorption technology is discussed to treat water from oil products. The comparative analysis of the most common non-organic, synthetic, organic and natural organic sorbents is given. Methods to recover oil from various sorbents are discussed. Key words: water treatment, oil products, sorbents.

Application of numerical study in flow structure to upgrade gravity settlers

The Numerical solutions of differential equations are obtained for two-phase flow in gravity settlers. The fields of velocities are plotted accounting for different settler designs. The options to upgrade settlers to ensure even phase distribution are outlined. Key words: gravity settlers, flow structure.

Caprolactam detection using two types of microbial biosensors

Laboratory prototypes of vial and throughput-injection type biosensors were developed based on bacterial caprolactam strain-destructor. The comparative characteristics (for throughputinjection/ vial type systems, respectively) were obtained: single measurement duration – 12/15 min, the detection threshold – 0005/0.02 mM, operating stability – 5.3/9.8%, long-term stability – 10/14 days. The data on real samples (sewage discharge and bio-treatment) indicate the practical application potential for both types of biosensors to deploy in environmental monitoring systems.

Activated water effect on Trichoderma micromycets

The effect of electrochemically activated water (EAW) is explored for industrial and agricultural important strains of Trichoderma isolated from hydrosphere. Treatmeent of micromycet conidia by EAW led to the change in growth rate and development of micromycetes. A reliable increase in germinating rate of conidia in all isolates was registered caused by catholite effect, whereas anolite inhibited the process. All strains studied showed a depressed specific growth rate (μ) after exposure to activated water compared to control. Treated fungus Trichoderma strains had strong antagonistic effect on Fusarium spp. The change in type ofinteraction between the culture fluid of micromycetes treated with EAW containing the plant was detected.

Implementation of rental relations in water use practice

Transition to market economy resulted in fact that the State ceased to be the sole owner of economic entities; fixed assets in numerous large and small enterprises became the property of private owners. Currently, the companies using highly efficient water resources generate profits because of high weight of rental cost component, or water rental costs. Under effective legislation in the water use domain there are no provisions to revoke rent in favor of the owner of water resources or the State. Therefore, today the issue of forming an effective economic mechanism to manage water resources in Russia is of ultimate importance.

Information support system to run environmental statistical analysis

The information framework to run statistical analysis of environment is discussed. Conditions to set forth the initial information database to studyenvironment background, its specificity are controlled by detail of primary data. The description of the main formats of environmental statistical reporting to be submitted to the regional environmental protection committees are developed. They can be used for statistical studies.
