Water Recycling Plant

Reclaimed water or recycled water is former wastewater (sewage) that is treated to remove solids and impurities, and used in sustainable landscaping irrigation, to recharge groundwater aquifers, to meet residential, commercial and industrial water needs, and for drinking.

We manufacturer and exporters, Bestech offers a wide range of Waste Water Recycling Plants to our clients. Range of products offered by us is manufactured in accordance to international quality standards using premium quality raw materials.

Waste Water Recycling Plant

We are one of the leading manufacturer and exporter of a wide range of high quality Waste Water Recycling Plant. Based on biological, chemical, physical and membrane/ion exchange processes these products are engineered using efficient machinery and high quality raw materials. Known for their ability to purify colloidal and suspended impurities from waste waters, these products are brought into application in a variety of industries. Ability to remove viruses, bacteria and other inorganic and organic germs makes these products one of the most appreciated products in the industry. We also offer customized solutions of our products as per specifications of our clients. Plants offered by us are durable, reliable and easy to handle and are used in chemical, textile, food, mining and beverage sectors. Water treated by these plants are used for fire fighting, gardening and other such kind of non-portable applications.

The main features of our range of waste water recycling plants are:

  • Highly effective
  • Lesser power consumption
  • Manufactured using innovative technology

Water Treatment of fresh water involves the following key steps:

Primary Steps

  • The water is mixed to liberate dissolved gases and to suspend particles in the water column. Sometimes a pre-oxidation step is also performed at this stage.
  • Flocculation: In this step coagulants are added to remove the suspended particles (clay, organic material, metals, microorganisms), which stick to the coagulants forming heavy particles.
  • Sedimentation: The heavy particles (flocs) settle to the bottom leading to clear water.
  • Filtration: The water is run through a series of filters, which trap and remove particles still remaining in the water column. Typically, slow or rapid sand filtration and more recently membranes or reverse osmosis are used to accomplish this task. Due to growing concerns regarding micro-pollutants, additional treatments such as advanced oxidation processes, activated carbon adsorption alone or combined with ozonation or H2O2 are sometimes used to remove these trace organic compounds.
  • Disinfection: The water is now largely free of particles, organics and microorganism and is now treated to destroy any remaining disease-causing pathogens. This is commonly done with chlorination, ozonation, hydrogen peroxide, or UV (Ultran Voilet) radiation (similar to the point of use UV tubes). The water is then sent to the pumping station for distribution to homes and businesses. Chlorination is the most widely used disinfection method because it permits maintaining residual chlorine at a level efficient enough to guarantee the absence of microorganism until the water has reached its point of use.

When drinking water is produced from the sea, the water is desalinated by electrolysis or membranes such as reverse osmosis or by a solar process desalination.

Drinking water treatment plant operation and maintenance includes the following tasks:

  • Operate and adjust equipment controls to purify and clarify water.
  • Inspect equipment and monitor operating conditions, meters, and gauges to determine load requirements and detect malfunctions.
  • Add chemicals, such as ammonia, chlorine, and lime, to purify and disinfect water and other chemicals, such as ferric chloride, peroxide, and polymers, to enhance water treatment.
  • Collect and test water samples, using test equipment.
  • Record operational and laboratory data, observations of processes, and meter and gauge readings on specified forms.
  • Clean and maintain tanks, basins and filter beds, using hand tools and power tools.
  • Maintain, repair, and lubricate equipment, using hand tools and power tools.

Many of these tasks can be automated in modern treatment plants but trained operators and engineers are still required to control and maintain the system. Moreover, operation of the treatments also requires a significant amount of chemicals, which might not be available in little industrialised or remote areas..

Applicability

Centralised drinking water treatment plants are useful when water is supplied from a source containing natural or anthropogenic contaminants such as lakes, rivers, seas or groundwater. Many different types of raw water can be purified in treatment plants as processes are designed for each case considering water quality and desired capacity.

The treatment plants need to be maintained by skilled labour to regularly control water quality and optimise processes.

Smaller drinking water treatment plants may be installed at semi-centralised level or point of use in order to minimise energy requirements for distribution.
