About Envirotech Our Team

Chemical Industry Effluent Treatment

  • Chemical industrial waste usually contains organic & inorganic matter in varying degree of concentration, low suspended solids, and high BOD/COD ratio.
  • Mainly materials in the chemical industry wastes are mutagenic, carcinogenic or simply hard to degrade.
  • We offer ASP, MBBR, SBR and in some cases anaerobic-aerobic treatment methods.

Pharmaceutical Industry Effluent Treatment

  • Pharmaceutical industrial effluent contains high COD (6000-115000 mg/l), high BOD (2500-45000 mg/l) due to high soluble & insoluble organics with high total dissolved solids & total solids with varying pH.
  • Nutrients such as Phosphorus, Nitrogen are in the effluent.
  • Organic pollutants are mainly from raw materials & finished products. They are mostly polar & potentially resistant to bio-transformation.
  • Depending upon organic load and degradability, We offer anaerobic treatment followed by aerobic and tertiary treatment.
  • Effluent nature and treatment solution differ from company to company.

Distillery Effluent Treatment

  • Effluent originating from distilleries known as Spent Wash leads to extensive water pollution.
  • Low pH, dark brown colour, sweet odour, high temperature, high oil & grease, high values of total solids
  • High BOD & COD values. The suspended solids and colloidal solids in the effluent contribute high BOD (30000-60000 mg/l) and COD (65000-125000 mg/l).
  • The dissolved oxygen content of the raw effluent is below detectable limit.
  • We are having proven treatment scheme for distillery spent wash having anaerobic-aerobic treatment with energy recovery through biogas.

Fruit Effluent Treatment Plant

  • Production of fruit juices & drinks, fruit concentrates, sauces, peel pressuring products have impact on our environment.
  • Produced effluents originating from Fruit processing industries and in Soft drinks have high concentrations of soluble and insoluble (suspended) organic material.
  • It has low pH, imbalance of nutrients, high COD (1000-20000 mg/l), high BOD values, toxins, high TSS.
  • Effluents from fruit processing industries varies from factory to factory and is dependent on varies parameters such as the type of production, kind of end products and type & quality of the fruit used as ground production.
  • We offer combination of anaerobic-aerobic process to handle effluent from the industry, in some cases primary treatment also included in the treatment scheme.

Engineering Industry Effluent Treatment Plant

  • Contamination of waste streams includes waste oil, coolant, benzene, naphthalene, phenols and cyanide with a range of more complex organic compounds known as Polycyclic Aromatic Hydrocarbons (PAH).
  • Effluent contain moderate COD (250-2500 mg/l), BOD, high suspended solids (1000-5000 mg/l), high oil and grease content, heavy metals etc.
  • Considering effluent load and parameters, we offer primary treatment such as DAF, chemical precipitation followed biological treatment such as Extended Aeration, ASP, and Anaerobic-Aerobic process.

Beverages Industry Effluent treatment

  • High BOD (1200-2500 mg/l), COD (2500-4500 mg/l), pH (6-9).
  • Less discharge of oil & grease, high solid content, organic matter, dark yellow colour.
  • Bottle washing or cleaning of machines and equipment also requires enormous amounts of clean water and generates effluent.
  • We offer anaerobic-aerobic process (UASB reactor followed by EA) and tertiary treatment for fine tuning. In some cases, we also suggest DAF for primary treatment.

Slaughterhouse Effluent Treatment

  • Wastewater from slaughterhouse & meat processing industries has been classified by CPCB as the most harmful to the environment.
  • Wastewater contains large amount of blood, fats & hair.
  • It contains high BOD (2000-5000 mg/l), COD (4000-10000 mg/l), oil & grease, high organic matters (i.e. proteins, fats, blood, lard) & possible high chloride content from salting skins.
  • For slaughter house treatment, we offer biological treatment (anaerobic-aerobic, mostly anaerobic filter and EA) followed by tertiary treatment. Before biological treatment, DAF is provided and mostly used for high TSS and O&G removal.

Paper & Pulp Industry Effluent Treatment

  • Pulp and paper mills are categorized as a core sector industry and are the fifth largest contributor to industrial water pollution. Pulp and paper mills generate varieties of pollutants depending upon the type of the pulping process.
  • Paper manufacturing process release chlorinated lignosulphonic acid, chlorinated resins, chlorinated hydrocarbons in the effluent are the major contaminants formed in the effluent of Paper & Pulp mill.
  • Pulp and paper industrial effluent is rich in recalcitrant compounds and causes pollution. High BOD, COD due to presence of toxic lignin & its derivatives from raw cellulosic materials & strong black-brown color.
  • We offer anaerobic aerobic process for the treatment of paper and pulp industry with excellent outlet results.


  Operation & Maintenance of ETP

The Effluent Treatment plant once constructed/established need to have operation & maintenance through qualified & experience persons to serve efficient & effective operation of ETP, qualified operator & supervisor are being provided by us who maintains all the records of the operation and attends the day to day trouble shooting.

Effluent or Sewage Treatment plant Operation and Maintenance Staff Requirements:

The manpower requirement for ETP or STP Operation and Maintenance can broadly be listed as follows:

  • 1)    Supervisor : is an individual with environmental engineering or science /Graduate or Post Graduate Background with experience of at least three years on similar plant(s).
  • 2)    Plant Operator(s): is an Individual with at least a High School Pass with sciences and be physically fit and mentally alert. Comprise a team of
    qualified / trained operators who work in shifts in operating and maintaining screens, grit removal devices, pumps, aerators, valves, etc.
  • 3)    Laboratory Analysis: is a qualified individual should be at least B.Sc. with chemistry who has knowledge of water and waste water chemistry and is trained in preparation of laboratory chemicals, use of laboratory instruments, collection and preservation of water / waste water samples and analysis for various environmental parameters such as pH, SS, BOD, COD, TDS etc.

Above staff is used to run ETP or STP effectively which gives proper result set by Pollution Board

ETP or STP Operation & Maintenance is Introduction of: Various unit operations and processes (separation by Screening, Sedimentation , Filtration, Neutralization, Coagulation, Flocculation, Absorption, Adsorption, Chemical reaction, Oxidation/Reduction, Dissolution, Ion exchange, Chlorination)

Operation of Units: Screens (Coarse / Fine Bar screens, Manual/ Mechanically operated), Sumps and Pumping Stations including Pumps, Motors and Panels (Centrifugal Horizontal / Vertical Turbine), Valves(Sluice gates, Non return, Reflux), Pipes/Specials and Pipe Joints, Grit Removal Units. Primary Sedimentation / Settling tanks, Scraping Mechanisms, Sludge withdrawal, Sludge Sumps, Sludge Pumps, Aeration tanks and Aerators, Secondary Settling Tanks, Secondary Sludge Sumps, Pumps, Sludge Thickeners, Sludge Digesters, Gas Production, Sludge handling and Drying.
