Wastewater treatment has become a mandatory step of any construction or project, right from the conceptual stage. In this article, let’s learn about the issue of wastewater treatment in small-scale construction projects with NTS.

Description of characteristics

  • Office buildings
  • Family clinics
  • Detached houses, high-end houses
  • Traditional craft villages
  • Construction projects over many years, …
  • High-end resorts, with separate resorts
  • Eco-tourism areas, homestays, … installed separately for dispersed toilets
  • Factories and factories do not generate production wastewater, but generate domestic wastewater from workers and employees.

In reality, the amount of wastewater generated from small-scale construction projects as mentioned above and households, residents, … has made the environment increasingly polluted, causing a significant impact on water sources. Finding a timely treatment method is a way to protect the living space and health of everyone. Wastewater contains hundreds of thousands of tons of organic matter, grease, nutrients and microorganisms, bacteria, etc. If not treated and allowed to seep directly into the soil, it will lead to serious damage to the surrounding environment, causing serious pollution of groundwater and surface water. In addition, it can also be whistled and warned by the authorities. Wastewater treatment methods and technologies are selected based on the following suggested bases:

Capacity scale and drainage characteristics (dispersed basins of urban areas, residential areas, residential areas, etc.)
Characteristics of wastewater receiving sources
Level and stages of wastewater treatment required
Natural conditions of the area: climate, weather, terrain, hydrogeology
Conditions of supplying raw materials for wastewater treatment in the locality
Area and location for wastewater treatment
Financial resources and other economic conditions, etc.
Who should be concerned

Architects and engineers who are establishing and managing projects. They need to find wastewater treatment solutions for the projects they are in charge of For water supply and drainage engineers, environmental engineers who are looking for solutions for their design documents/drawings Usually designed by construction consulting companies. Because they are small, they are subjects that investors or contractors think are easily overlooked or justified. High installation costs. This is a problem for investors who are having financial difficulties, need to optimize costs and focus their investment budget on equipment that generates direct revenue. Image

What is the solution to the above problem?

– Choose available equipment at a reasonable cost. A request for environmental contractors, you will usually receive a popular solution with traditional technology. With the above technologies, the wastewater treatment project requires a lot of machinery, equipment and installation space. Sometimes the applied technology is too advanced, compact but the cost is very high, making investors discouraged. Therefore, investors need a suitable solution – Simple control and operation. Meet the specific needs of each project. – Reasonable cost – Compact, easy to install, easy to move…

Some small-scale wastewater treatment systems applied in practice

Treatment by Mobile Module

Figure Including continuous biological treatment processes, combining microbiological systems: anaerobic, anoxic, aerobic to treat wastewater. Under the effect of decomposing pollutants by microorganisms, wastewater will be treated before being discharged into the environment. In the treatment compartments, different biological processes occur in turn based on the oxygen needs of microorganisms, from which they will use pollutants as a food source to synthesize cells, they decompose organic substances in wastewater into simple inorganic compounds. From there, pollutants are removed. To ensure clean water meets current standards, treated water will be disinfected. To kill harmful bacteria before entering the receiving source, or used for other reuse purposes. Mobile modules will be designed by NTS engineers to suit different types of wastewater from each family and business to optimize investment and operating costs, in order to achieve the most effective project.

Advantages

  • Design of each compartment with wastewater treatment tasks in the same Module
  • Composite, PE, or steel materials, …
  • Anti-rust, anti-corrosion paint, no odor
  • Compact size, high aesthetics, easy to move, change position
  • Can be placed above ground or underground as desired according to the investor’s choice
  • When brought to the unit, just connect the inlet pipe, the water flows out.
  • Diverse treatment capacity, suitable for many households, many types of wastewater with different properties, …
