Surface Water Treatment Plant

The surface water treatment plants are made of simple physico-chemical treatment systems which are designed to provide drinking water. Their design is compact, and they are built in order to ensure minimal space and to be containerized.

Process technology and equipments:

  • Pumping water system from the entry into the tubular reactor (rough materials retention prefilter included)
  • Dosing reagent system
  • Additive dosing for PH adjustment
  • Oxidants dosing (sodium hypochlorite, potassium permanganate, etc.)
  • Additive dosing for flocculation-coagulation
  • Lamellar settler
  • Treated water tank
  • Pumping the treated water into the filters
  • Automatic filters for turbidity retention
  • Chlorination
  • Drinking water storage and pumping
Treatment plan

The supply water, free of solids such as gravel, leaves, etc., is sucked by a centrifugal pump equipped with a protective prefilter to retain solids.

Next, the water enters a tubular reactor with forced circulation, where are injected the appropriate chemicals in order to obtain the pH values prescribed for drinking water. In this phase there are also dosed coagulation / flocculation agents for a more advanced solids settling of  and oxidants for pre-oxidation of certain substances that give color or contaminate water (iron, manganese, ammonia, nitrates, organic substances, microorganisms such as bacteria, algae, plankton, etc.). Dosage is performed using electromagnetic diaphragm metering pumps, resistant to all used substances and mounted on their tanks.

Next the water is send to a special designed lamella settler in order to obtain an advanced solids deposition, in the smallest space available and according to a specific retention time for the precipitatation of certain materials from raw water.

Lamellar settling tank contains various components, each with its particular function. The first is water inlet chamber, which already contains the appropriate chemicals. In the second chamber there are sets of blades that allow water to flow up through the channels, leaving the solids behind the walls, thereby purifyng the water. Solids fall to the bottom where the mud is colected.

In the following stage, the water enters a tank from where is sucked by a centrifugal pump and discharged in two filters in order  to reduce turbidity, where fine particles (bigger than 5-10 microns) which could not be retained in lamellar settling, are removed. The filter system consists of a dual battery that feeds two automatic filters with quartz sand of 0.5-1.2 mm. The two filters are automatically washed in counter-current at a predetermined time. In this way ensure long usage of the filter with a very low maintenance cost.
Once filtered, the water is chlorinated by appropriate dosage to maintain a free residual chlorine content which guarantees the drinkability of the water. Chlorination occurs through an electromagnetic metering pump membrane. The purifyed water is led into a storage tank and is delivered to the consumer through a pumping group.
