Welcome To PFS Water Treatment Engineering - Effluent Treatment Plant Manufacturer | Pune | Aurangabad | Maharashtra.

We design, manufacture, supply, erect and commission effluent treatment plants of various capacities and for various effluent types. For pollution control requirements of various industries like chemicals, pharmaceuticals, textiles, leather, electroplating, electronics & electrical, mechanical, etc. Effluent treatment plant (ETP) is very cost effective and proven system for removal unwanted, hazardous chemicals and metals.

Packaged Effluent Treatment Plant

Effluent Treatment Plant (ETP) is a industrial waste water treatment system with aim to produce effluent which is reusable and environment friendly. Effluent treatment plants help businesses to adhere to environment norms set by regional pollution control boards. we design manufacture various types of effluent treatment plants to treat wide range of effluent qualities. The process is combination of many treatment techniques like physical separation, physio-chemical treatment, adsorption, depth filtration, reverse osmosis, disinfection, etc. Contingent upon the business, modern effluents contain different materials. A few effluents contain oils, and some contain poisonous materials (e.g., cyanide and other metals). Effluents from sustenance and refreshment industrial facilities contain degradable natural toxins. Since modern waste water contains a decent variety of debasements and in this manner explicit treatment innovation called ETP is required. 

Advantages and Benefits

  • Recycling of waste water
  • Produces environment free waste water before discharging
  • Helps businesses to adhere pollution control norms
  • Reduces fresh water requirements
  • To safeguard environment against pollution and contribute in sustainable development

Civil Effluent Treatment Plant

Effluent treatment process is divided into four major parts as

Treatment Mechanism 
  • Physical
  • Chemical
  • Biological

Preliminary Treatment Process

Physical separation of large size contaminants like cloth, plastics, wood logs, paper, etc. that can interfere with treatment process are removed in this treatment process.
Common physical unit operations at Preliminary level are:
Screening: A screen with uniform openings up to 10 mm are used to remove large sized contaminants.
Sedimentation: This is physical water treatment process that uses gravity as driving force to remove suspended solids.
Clarification: Primarily used to separate solids from water.

Primary Treatment Process

Removal of floating and settleable materials such as suspended solids and organic matter. Both physical and chemical methods are used in this treatment level. Chemical unit processes are always used with physical operations and may also be used with biological treatment processes. Chemical processes use the addition of chemicals to the wastewater to bring about changes in its quality.
Example: pH control, coagulation, chemical precipitation and oxidation.
pH control is done to adjust the pH in the treatment process to make wastewater pH neutral.
For pH control following chemicals are commonly used
For acidic wastes (low pH): NaOH, Na2CO3, CaCO3or Ca(OH)2.
For alkali wastes (high pH): H2SO4, HCl.
Chemical coagulation and Flocculation
Coagulation refers to collecting the minute suspended solid particles dispersed in a liquid into a larger mass.
Chemical coagulants like Al2(SO4)3 {also called alum} or Fe2(SO4)3 are added to wastewater to improve the attraction among fine particles so that they come together and form larger particles called flocs.
A chemical flocculent (usually a polyelectrolyte) enhances the flocculation process by bringing together particles to form larger flocs , which settle out more quickly. Flocculation is aided by gentle mixing which causes the particles to collide.

Secondary Treatment Process

Biological unit processes are involved to remove, or reduce the concentration of organic and inorganic compounds. Biological treatment process can take many forms but all are based around microorganisms, mainly bacteria.
Aerobic Processes
Aerobic treatment processes take place in the presence of air (oxygen). Utilizes those microorganisms (aerobes), which use molecular/free oxygen to assimilate organic impurities i.e. convert them in to carbon dioxide, water and biomass.
Anaerobic Processes
The anaerobic treatment processes take place in the absence of air (oxygen). Utilizes microorganisms (anaerobes) which do not require air (molecular/free oxygen) to assimilate organic impurities. The final products are methane and biomass.

Tertiary / Advanced Treatment Process

Final cleaning /polishing is carried out in this process that improves wastewater quality before it is reused, recycled or discharged to the environment.
