The Activated - Sludge process is a biological method of waste water 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, while simultaneously 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 known collectively as activated sludge.The MLVSS is maintained as 2500 - 3000 mg per Lt. The overall goal of the activated - sludge process is to remove substances that have a demand for oxygen from the system. 

MBRs were designed with the separation device located external to the reactor and relied on high trans-membrane pressure (TMP) to maintain filtration. With the membrane directly immersed in the bioreactor, submerged MBR systems are usually preferred to side stream configuration, especially for domestic wastewater treatment. The submerged configuration relies on coarse bubble aeration to produce mixing and limit fouling. The energy demand of the submerged system can be up to 2 orders of magnitude lower than that of the side stream systems and submerged systems operate at a lower flux, demanding more membrane area.In submerged configurations, aeration is considered as one of the major parameters in process performance both hydraulic and biological.

Electro-coagulation is a unique and latest technology successfully implemented in developed and developing countries. The Advantages of Confident electro-coagulation system are follows. Electro-coagulation is the process of destabilizing suspended, emulsified or dissolved contaminants in an aqueous medium by inducing an electrical current in to the medium. The electrical current provides the electromotive force to drive the chemical reactions.

Dissolved Air Flotation is a liquid or solid separation process in which microscopic air bubbles (10-10O`i) become attached to solid particles suspended in liquid, causing the solid particles to float. In a OAF system air is dissolved into liquid under pressure The dissolved air remains in solution until the pressure is release, to atmospheric pressure, causing the air to come out of solution in the form of microscopic air bubbles. The bubbles are mixed intimately with the wastewater and become attached to the solids in the waste stream causing the air solids agglomerate to float to the liquid surface where a solids (float) blanket formed. Surface skimmers then remove the float blanket.

A typical pressure sand filter consists of a pressure vessel - this could be either vertical or horizontal-fitted with a set of frontal pipe work and valves, graded sand supported by layers of graded under bed consisting of pebbles and silex, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water. Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. The fluid that passes through is called a filtrate

The usual filter medium is sand but other materials - anthracite, garnet, manganese dioxide, are used for special applications. Water enters the top of the vessel and flows downwards through the bed of media and leaves through a collector system at the bottom. Contaminants are removed through straining and or or adsorption depending on the chosen media. shows a schematic of a typical granular media pressure filter.

Ozone (03) is formed by the combination of three oxygen atoms. An unstable gas with a strong and irritating odor (which explains its name), ozone is corrosive, a strong oxidant and very toxic. For all of these reasons it absolutely unsuitable to sustain life. Ozone is generally produced by generating high-power electrical discharges in air or in oxygen. Naturally found in the upper layers of the atmosphere, where it is formed by a photo-chemical reaction ozone serves as a shield which protects our plants from the sun`s ultraviolet radiation.State-of-art research laboratory in our main facility is actively into various application of ozone technology, product innovation, design development and extensive testing. Our Research and Development team works extensively on ozone based technologies and comes up with leading edges products and solutions.

Zero liquid discharge (ZID) is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle.

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.

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, calle 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.
