Rural water and wastewater treatment systems
Small cities, urbanizations, resorts, and villages tend to discharge less wastewater than large cities with centralized systems.These consumers need high-quality and affordable wastewater treatment. They need autonomous solutions.
Pumping wastewater to wastewater treatment plants in nearby cities is costly and inefficient in terms of energy consumption.
Many rural areas traditionally have difficulty with imperfect, conceptually outdated wastewater treatment plants. When possible, a cost-effective and sustainable solution for on-site wastewater treatment is used with reuse of water for irrigation of crops or return to nearby rivers.
An inexpensive autonomous system will allow local communities to process wastewater from homes and businesses without additional costs. This is considered a much more rational solution than collecting and transporting sewage for treatment to other facilities.
Portable water treatment systems are quiet, odorless. This is a compact equipment that does not take up much space. These are sustainable and affordable solutions for isolated communities. Moreover, these facilities are autonomous and can be controlled remotely via the Internet.
Reuse of wastewater for irrigation is a very important element of modern integrated water resources management. This technology saves river water while reducing the amount of pollutants discharged into waterways.
Waste water reuse provides a reliable source of water independent of drought, weather variability and population fluctuations during the holiday season. Modern compact WWTPs save money and provide security regardless of seasonal factors.
Nutrients that can be recovered from wastewater are used to fertilize local crops and reduce farm costs.
This provides environmental benefits, as well as lower costs for further water treatment.
Private water and wastewater treatment systems
The construction of a new residential development usually involves the construction of expensive pipelines and the construction of pumping stations for transporting wastewater to a centralized municipal sewage treatment plant.In many cases, these are expensive projects that involve the modernization of main pipes and sewage treatment plants to cope with the increased flow of sewage water.
Many communities wastefully use drinking water for landscaping, irrigation of parks and playgrounds, heating and cooling systems. Customized solutions for water and wastewater treatment plants have a great economic and environmental meaning.
MABRs are a fully automated solution that is ideal for large farms or remote isolated communities. Membrane aerated biofilm reactor turns waste water into a source of quality irrigation water.
The advantages of private wastewater treatment plants are obvious:
• Reduced energy and water consumption.
• Savings on the construction of the water supply system.
• Compliance with strict quality standards.
• Reduced environmental damage.
Such systems are autonomous and able to function for several months with remote control and minimal maintenance. This is a huge savings in operating costs and a strategic source of water resources.

The main types of wastewater treatment plants
Wastewater treatment is a complex of technological processes aimed at improving water quality in order to make this by-product of economic activity suitable for further use.There are two large groups of wastewater treatment plants (WWTP):
1. Chemical and physical treatment plants
This type of plant is based on a sequence of chemical reactions and physical processes for wastewater treatment. Such plants are mainly used for wastewater treatment from industrial enterprises, factories and plants.Most industrial wastewater contains chemicals and other toxins that can cause significant environmental damage. As a rule, they are well removed by chemical and physical methods.
2. Biological wastewater treatment plants
Biological wastewater treatment plants use biological mass (bacteria) to break down waste. Biological treatment is ideal for treating wastewater from households and offices.The stages of the technological process mainly depend on the type and degree of contamination. Wastewater treatment consists of a combination of physical, chemical or biological processes and operations to remove solids, organic substances.
Modern technologies for surface water treatment
The requirements for water quality over the past years have been continuously changing, dictating new approaches to surface water treatment. Along with the number of chemical / physical methods, more advanced biological processes have been introduced.Water quality and types of impurities
Pure water is a liquid without color, odor and taste.It is capable of dissolving most minerals and can carry other organic or inorganic compounds, as well as microorganisms in suspended form. Thus, natural water always contains impurities.
The main inorganic ions that are found in most surface waters are calcium, magnesium, sodium, potassium, iron, manganese, bicarbonate, chloride, sulfate, nitrate, phosphate and fluorine.
Depending on the source of the water, other inorganic ions may be present in it.
Minimum amounts of most inorganic ions, especially minerals such as calcium, magnesium, sodium, potassium or iron, are necessary for human life and must be present in drinking water. Other ions can be toxic, as well as transcendental concentrations of basic elements.
Alkalinity, hardness, amount of dissolved solids, conductivity, turbidity and stability are indicators of the quantity of inorganic impurities in water. Organic pollutants can be natural and synthetic compounds of various chemical structure.
The variety of these substances requires an individual approach to the water treatment technology.
Natural organic substances in surface waters are proteins, carbohydrates, and lipids that come from plant or animal residues. The interaction of these compounds with water leads to the formation of various chemical groups, such as carboxyl or methoxyl.
The main synthetic organic compounds that can be found in water are surfactants, pesticides, herbicides, as well as solvents, polychlorinated biphenyls, and disinfection by-products. In world practice, such indicators of water quality and the amount of organic compounds as BOD5, COD, TOD, color, UV absorption and fluorescence are used.
A separate group of pollutants is represented by microorganisms, which are potential sources of infectious diseases of humans and animals. These are bacteria, viruses, fungi, algae, protozoa and parasitic worms. Each water source and type of pollution requires a unique technological process, which is selected after conducting comprehensive studies at the facility.
Our consultants will give you details about the advantages, disadvantages and cost of specific technical solutions for water and wastewater treatment plants.
