Activated Sludge Biological Process

The Activated Sludge process is a Biological method of wastewater treatment that is performed by a variable and mixed community of microorganisms in an aerobic aquatic environment. These microorganisms derive energy from carbonaceous organic matter in aerated wastewater for the production of new

cells in a process known as synthesis, whilesimultaneously releasing energy through the conversion of this organic matter into compounds that contain lower energy, such as carbon dioxide and water, in a process called respiration.

This consortium of microorganisms, the biological component of the process, is know collectively as activated sludge. The MLVSS is maintained as 2500 - 3000 mg/L . The overall goal of the activated-sludge process is to remove substances that have a demand for oxygen from the system. This is accomplished by the metabolic reactions (synthesis-respiration and nitrification) of the microorganisms, the separation and settling of activated-sludge solids to create an acceptable quality of secondary wastewater effluent, and the collection and recycling of microorganisms back into the system or removal of excess microorganisms from the system. This is achieved by the Efficient design of the Secondary classifier and Sludge Re-Circulation system.

Fluidized Bed Bio-reactor

Removes hydrocarbons and BOD/COD in contaminated water through an attached growth biological treatment technology.
Uses oxygen transfer with a large protected biofilm attachment area to achieve high removal rates.
Incorporates neutrally-buoyant Media Pac.

Increases the efficiency of the biological treatment process by increasing the amount of surface area.
Capable of treating a variety of flow rates and contaminants.
Simple and easy to operate and maintain
Minimal maintenance compared to other biological treatment systems.
The FBBR Media Pac incorporates high surface area and large void spaces that are aggressively sloughed to eliminate bioflim growth and fouling.
Easy to test influents and adjust biological parameters for maximum efficiency.

Sludge Management

The Sludge management consist of different distinct functions such as Solid Liquid separation, Sludge Thickening , Sludge De-watering and Sludge disposal. The following Equipments manufactured by Confident play significant role in Sludge Management Process.

High Rate Solid Content Clarifier
Sludge Thickener
Filter Press
Hydro Extractor
Decanter

Salt Recovery

During the reactive dyeing of cotton, salts such as sodium chloride (NaCl) are placed in a dye bath to aid the exhaustion of various dyes onto the fabric while bases are added to raise the pH from around neutral to pH 11 to achieve fixation. Afterwards, the used dye

bath solution, called dye bath, is discharged with almost all the salts and bases added as well as unfixed dyes. Consequently, many raw materials are lost in the waste stream ending up in the environment as pollutants. When the other polluting components are treated with different treatment techniques mentioned in this brochure,

the salt remains same in the effluent resulting in high TDS. The NaCl salt solution can be recovered for Re-use in Dyeing by using nano filtration membrane system.

Benefits of Nano Filtration System

Hardness less than 10 mg/L.
Compliance of TDS value of less than 2100 mg/L is achieved as per Pollution control norms.
Faster payback on investment due to savings in Salt.
Enhanced Repeatability of Dyeing process due to consistent salt solution.

Ultra Filtration and Re-cycling Plant

Ultra Filtration system is an effective pre-treatment for Reverse Osmosis Re-Cycling plant and Nano Filtration plant. Ultra Filtration comprises of Hydrophilic PVC Hollow fiber Membranes. The Pore size is 0.01 to 0.1 Micron.

Benefits of Ultra Filtration system

Turbidity less than 0.10NYU.
SDI less than 2.
Consistent output water Quality.
pH range from 3 to 12 .
Bacteria removal up to 99.99 %
Easily back washable.
Increase the life of Nano and RO membranes.
Low operating cost.
Chlorine tolerance up to 200 mg/L.

Reverse Osmosis System
RO system is the only available option for Re-cycling and re-use of process waste water, After the Effective ETP and Pre-treatments, the final outlet water is fed to the RO

membrane system which gives the Permeate as a pure Re-useable water with more than 95% salt rejection. Poly-amide Low fouling membranes are used in RO systems.

90% of the Feed water is recovered in the RO system.
The system is installed with Automation for Pressure, pH, ORP and Flushing and monitoring the Flow, pH and TDS in Feed, Permeate and Reject.
On Line Dosing of Anti-Scalant, Anti Oxidant and Acid.
De-Gassifier Tower is used to remove the Alkalinity and Bi-Carbonates in the Permeate Water before Re-Use.
Permeate water TDS is less than 100 mg/L, Hardness Nil, pH 6-6.5.
Renewable Water source to save the environment.
