EFFLUENT TREATMENT PLANT MANUFACTURERS IN PUNE
We design, manufacture, supply, erect and commission effluent treatment plants of various capacities and for various effluent types. For pollution control requirements of industries like chemicals, pharmaceuticals, textiles, leather, electroplating, electronics & electrical, mechanical, etc. We PFS Water Treatment Solutions are effluent treatment plant manufacturers in pune. Effluent treatment plant (ETP) is very cost effective and proven system for removal unwanted, hazardous chemicals and metals. Effluent Treatment Plant (ETO) is widely accepted waste water treatment technique which is especially intended to cleanse industrial waste water for its reuse and preventing environment by removing / eliminating harmful contaminants that might be present in wastewater. Industrial effluents vary industry to industry in nature and harmfulness of contaminants, like some effluents may contain toxic materials, oils & greases, heavy metals, hazardous chemicals, organic / inorganic contaminants, etc.. As effluent form each industry vary in quality and quantity, specific and tailor made effluent treatment systems are required. Effluent Treatment plants have various stages which can be combined into groups as preliminary treatment, primary treatment, secondary treatment and tertiary treatment, and includes many physical, chemical, biological, and membrane technologies to process wastewater.
Key Advantages & Features
- Reduces fresh water requirements in industry
- Recycles effluent water from industry
- Prevents environment from contamination
- Help industries to adhere government rules and regulations
- Reduces costs for water acquisitions
INDUSTRIAL EFFLUENT TREATMENT PLANT MANUFACTURERS IN PUNE
Industrial wastewater treatment plant train comprises of various sections like..
- PRELIMINARY TREATMENT
- PRIMARY TREATMENT
- SECONDARY TREATMENT (BIOLOGICAL TREATMENT)
- TERTIARY TREATMENT (ADVANCE TREATMENT / DISINFECTION)
PRELIMINARY TREATMENT - ETP MANUFACTURERS IN PUNE
Main objective of this treatment stage is to remove course materials and other large contaminants from wastewater like wood, plastic, paper, cloth, metal, etc. This treatment stage in necessary to prevent subsequent stages from clogging and save on unnecessary maintenance costs. Preliminary operations include course screening, grit removal and in some exceptional cases comminution of large material.
Screening :- A very first unit operation in industrial wastewater treatment plants. Its objective is to remove course materials and large contaminants from wastewater by means of screens with uniform openings( generally 1 inch – 3 inch apart ). Available in many designs which are manual as well as automatic (Mechanically) cleaned.
Grit Removal :- Grit removal process in very important and necessary to prevent pumps and other instruments by damaging from sand, gravel or other metal particles
Sedimentation and Clarification :- It is a physical water treatment process which uses gravity as a driving force to remove solids from water. This removal of particulates is done in sedimentation tanks or also known as sedimentation basins.
PRIMARY WASTEWATER TREATMENT
Primary treatment process include chemical as well as physical methods to remove floating and settleable solids and organic matters. Main stages include pH controlling, coagulation, flocculation and sedimentation / clarification.
pH Control :- Objective of this unit operation is to maintain pH of wastewater within acceptable limits for subsequent treatment process. In this stage acids and alkalies are added in wastewater at calculated measures.
Coagulation and Flocculation : – In coagulation process small / minute particles which are dispersed in wastewater are collected together into larger mass. Common coagulants which are aluminium and iron based are added into wastewater to improve attraction forces among suspended particles so that they come together and form larger particles called flocs. Floculant generally a poly electrolyte is used to increase molar masses of coagulated particles resulting in faster settling of flocs.
SECONDARY WASTEWATER TREATMENT / BIOLOGICAL TREATMENT
Secondary wastewater systems are biological systems designed to treat effluent from primary wastewater treatment systems. Main objective is to remove soluble pollutants from wastewater. Secondary wastewater treatment systems makes use of microbial culture under proper environmental conditions which performs water decontamination function. General principles of secondary wastewater treatment
- Biological oxidation of remainder soluble organic matter after primary treatments.
- Settling of sludge generated during biological processes as well as absorption of particles that carried over from primary treatment.
- Removal of nutrients like ammonia, phosphorous and nitrates from wastewater.
Biological process can be classified according to their means of providing medium for biological growth.
- Suspended or slurry growth – Activated sludge process , Aerated lagoon
- Attached growth – Trickling filters, Rotating biological contactor
TERTIARY / ADVANCED WASTEWATER TREATMENT
This is the final treatment process in most industrial wastewater treatment plants before it is reused, recycled or discharged to environment / water bodies. Goal for this treatment process is to remove remaining inorganic compounds and substances like nitrogen and phosphorous. Viruses, bacteria and pathogens which are harmful / dangerous to public health are also removed at this stage.
Main objectives of tertiary wastewater treatment process
- Solids Removal
- Ammonia Reduction
- Phosphorous Reduction
- Disinfection Through Chemical and Mechanical Means
- Dechlorination for water discharge into the environment
- Organics Removal
