Effluent Water Treatment Plant

What is Effluent & Effluent Treatment Plant (ETP)?

Industries during the manufacturing process generates huge quantity of high toxic effluents which yield very high BOD, COD, TS and TDS level with collared and odor in effluent.

The Effluent Treatment Plant [ETP] plant is designed to treat the effluent coming from various areas of the plant. The treatment of different effluents varies with the type of effluent. Industrial wastewater contains a diversity of impurities and therefore for this reason alone, its treatment establishes a special task.

We are offering our clients with effluent treatment plant equipment that are appreciated for having sturdy construction and resistance to corrosion. These ETP plant are manufactured accepting industrial quality standards and are thoroughly inspected by our quality analysts before being delivered to the clients. We have the experience and capability to design and commission a host of clarifiers, filters, aeration, coagulation and settling systems for waste from industries like chemicals, drugs, pharma, refineries, lechates, etc.

Why to choose Excel Filtration Private Limited (EFPL) ?
EFPL has developed and offering a ZLD (Zero Liquid Discharge) system to recycle treated water for utility and process applications. We provide innovative and economical systems for waste with expertise is advantageously employed for the technical and economic optimization of every subsequent facility.

These ETP plant are manufactured accepting industrial quality standards and are thoroughly inspected by our quality analysts before being delivered to the clients.

Process Description of Effluent Treatment Plant

Effluent can be treated in a number of different ways depending on the level of treatment required. These levels are known as preliminary, primary, secondary and tertiary (or advanced). The mechanism for treatment is divided into three categories: Physical, chemical and biological.

Preliminary Treatment

Preliminary treatment removes in-organic materials and insoluble organic pollutants (i.e., large organic suspended solid matter, grit, O& G) that can be easily collected from the effluent and can damage or clog the pumps or skimmers of primary treatment clarifiers.

All preliminary treatments consist of physical separation techniques by controlling flow rate of effluents.

Units in Preliminary Treatment

It consists of temporarily holding the sewage in an inert basin where heavy solids can settle to the bottom where oil, grease and lighter solids float to the surface. The settled material go for sludge treatment in sludge digesters and floating materials are skimmed off and the remaining liquid is passes to secondary treatment. At this stage, over 70% of the suspended solids and 40% of the BOD is removed from the effluent.

Units in Primary Treatment

It is a biological treatment of effluent removes dissolved and suspended organic (bio-degradable) matters by consuming food and convert it into new cell mass, energy and CO2.

Most common micro-organisms are bacteria (aerobic or anaerobic), protozoa and rotifers, least common fungi and algae. This treatment removes almost 70- 90% of BOD and 80- 90% of dissolved solids from effluent. The under flow from the clarifier and the secondary clarifier having a sludge consistency of around 1-1.5% is pumped into the centrifuge for dewatering. The dewatered sludge is then disposed off suitably while the concentrate is taken back to equalization tank.

Units in Secondary Treatment

Tertiary treatment add additional cost to the treatment process and producing high quality effluent which can be reuse further for commercial and industrial applications. Treated water is sometimes disinfected chemically or physically depending upon the discharge location.
