  Operation and maintenance of Effluent Treatment Plant

The effluent treatment plant is designed to treat the effluent i.e. Wastewater recycling coming from different areas of the plant.

Industrial Waste

Water is one of the most important components

used in all type of industry. It is used in many processes of Industry. It may be used for washing, cooling, Heat Exchanging, condensing the steam etc. But Water used in industry is not totally consumed. Hence, almost all industries generate waste water from industries that needs serious action. So, improper discharge of waste water can pollute local Environment. In many manufacturing Industries, by-product can be treated as waste water called “Effluent” should be treated before it release into the environment.

Effluent is an outflow of water or gas from a natural body of water, or from a human made structure.

Effluent, in engineering, is the stream exiting a chemical reactor.

Effluent is defined as Treated or Untreated Waste water that flows out of a treatment plant, sewage, or industrial outlet.

So this treatment of waste water i.e. untreated effluent is turned into Treated Effluent with the help of Effluent Treatment Plant (ETP) sometimes it is also called as Sewage treatment Plant (STP). Clean water then is safely discharge into Environment.

Industrial Waste Water

Industrial waste water treatment covers the mechanisms and processes used for waste water treatment that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer).

National Standards for Waste Water

Effluent from industry must meet the National Standards for waste water set by Government. So, Effluent Treatment plant ETP or Sewage Treatment Plant (STP) should design & operated in such a way that it treats the waste water to these standards.

Effluent Treatment Plant:

Effluent Treatment plant can be operated with the help of 4 diff ways:

  • 1) Preliminary – Removal of Solids, Oil & Grease.
  • 2) Primary – Removal of floating & settable such as Suspended solids, Organic Matter
  • 3) Secondary – Removal of Biodegradable organic matter (BOD).
  • 4) Tertiary – Removal of residual suspended solids, Dissolved solids.

Operation & Maintenance of ETP or STP:

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 Envirotech Research Pvt Ltd 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) Plant Manager: 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 Analyst: 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 respective Govt.

   Pharmaceutical Industry & Bulk Drug Industry

A diverse characteristics of wastes are generated during manufacturing, maintenance and housekeeping operations in any pharmaceutical industry. Some of the typical waste streams comprise spent fermentation broths, process liquors, solvents, equipment wash waters, spilled materials, off-spec products, etc.

The pharmaceutical effluent is characterized with a high COD and high organic contents. For treating them, different types of treatments are required, like pH neutralization, Physico chemical process, aerobic/ anaerobic treatment, tertiary treatment involving activated carbon etc.

   Oil refineries & Solvent Extraction

The waste generated from the oil refineries demand special attention pertaining to their composition. The typical composition of such type of waster comprises neutralization wash water, spent liquor, cooling water, boiler blowdown, floor wash, carrier liquid of unwanted oil fractions, spillages etc.

In order to treat them, sedimentation and flocculation with lime alum and polyelectrolyte is performed. Moreover, activated sludge process is utilized as per the need and requirement.

   Engineering Industry

Engineering industries produces different varieties of effluent as per their role and position in the manufacturing chain. The typical composition shows the presence of oil, Coolent,metals, acids, phenols, cyanide, heavy metals, Fluorine, Chlorinated organic compounds, etc.

We provide a combination of mixed multi-stages of treatment, which comprises treatment by physical, chemical, biological methods accompanied by pressure filtration, disinfection, etc.

   Tyre Industry

Tyre industry owing to its spectacular growth contributes a significant amount of environmental pollution. The effluent generation takes place at various operational stages. The effluent from the company is mainly from Manufacturing Area, Water Treatment Plant ,floor Washing etc.

The treatment of such type of effluent demands treatment by aerobic process along with Primary Treatment and Tertiary Treatment.

   Hospitals

Owing to the spectacular growth of medical science and medical industry, the wastewater generation is witnessing a rapid growth. The principle sources of generation are surgery, drug treatments, radiology, laundry, operation room, chemical and biological laboratories, etc. Hospital wastewater effluents contain pathogenic microorganisms, pharmaceutical partially metabolized, radioactive elements and other heavy metals and toxic chemical compounds. Such wastewater is a potential environmental hazard.
