Waste Water Management

More than one among every six people in the world are “water-stressed”, i.e., they do not have access to potable water. Unfortunately, 1.1 billion people from the developing countries of the world fall into this category.

Water, as a resource, is a fast depleting body. Pollution, being one of the major concerns in the world today, make it nonetheless, more important for the waste-water treatment to be inevitable and extremely essential for saving pure water.

We, at Sparkle, provide potent solutions for purifying waste-water, domestic and diverse industrial purposes. While doing so, we ensure that maximum amount of water is treated to the level of being reused.

Basically, waste-water can be classified into two types: Sewage and Effluent.

For any Sewage, the major contaminants are biological-oxygen- demand, chemical-oxygen-demand and suspended impurities.

For removing suspended impurities, Sparkle provides primary settling with the equipment such as clarifiers and tube/ plate settlers .

Sparkle employs various technologies for treating chemical-oxygen- demand and biological-oxygen-demand, depending upon the requirement of the treated-water parameter conditions. For treating waste water, both the processes : the suspended growth process comprising of activated sludge process and extended aeration; and the attached growth process comprising of submerged aerated fixed film reactors and moving bed bioreactors are employed. The post- treatment process is generally, carried out with filtration and disinfection.

Sparkle also provides the combination - membrane bioreactors.

Sparkle waste water management solution offers value added services to its customers by supplying water of superior quality and large quantity.

Using innovative techniques, Sparkle enhances process efficiency and offers industry specific solutions for customized requirements.

The various processes involved in treating the effluent are industry-specific and therefore, customized accordingly.

Sparkle undertakes a systematic study of the effluent in its effectively designed Laboratory and conducts pilot trials before suggesting the solution. The solution provided is the combination of specific, biological and physical treatment.

At Sparkle, we believe in the LAST DROP CONCEPT, so we select the technology which wastes the least amount of water while purifying it.

Technology

Membrane Bio Reactor ( MBR )

Membrane Bio Reactor (MBR) is a combination of two basic processes i.e. biological degradation and membrane separation. They are merged into a single process where suspended solids and microorganisms responsible for biodegradation are separated from the treated water by membrane filtration unit.

Deep Bed Filtration

Deep bed filters are the variety of filters that use a porous filtration medium to retain particles throughout the medium, rather than just on the surface of it.

These filters are commonly used when the water to be filtered contains a load of particles because, in comparison to the other types of filters, they can retain a large mass of particles before becoming clogged.

Others

Various other technology used in water management treatment are Degasser which breaks weak carbonic acid into carbon dioxide and water. Degassed tower is considered in a DM water system or in D Alclysing system when the alcalynity in the water is very high and the pay back of degasser tower is favorable.

Nano Filtration is a stage of filtration between UF and RO where semi permeable membrane rejects high molecular weight salts. Nano filtration is essentially used for removal of hardness i.e, calcium and magnesium salts from water.

Products :

Micro / Membrane Filtration

Micron filtration is to segregate or separate particulate matter based on the size of the particulate matter. Sewing, screening or surface filtration are also the types of surface filtration based on size of the particulate matter.

When the requirement of filtration is less than 0.2 microns, then membrane filtration is also used. In water and waste water treatment, this type of filters are very critical. It acts as a guard filter to further membrane treatment. Micron / membrane filtration also restricts the presence of the organics, bacteria and virus.

Products :

Setting / Coagulation / Flocculation

Coagulation is predominantly used in effluent water treatment processes for separation of free oil, solids removal, water clarification, lime softening, sludge thickening, and solids dewatering. The negative electrical charge on particles are neutralized, which destabilizes the forces keeping colloids apart.

Clari Flocculation is a combination of clarifier and flocculation. There is a separate chamber provided for dossing flocculants in the unit. There are many types of Clari Flocculators like Central drive, peripheral drive, agitator gate type etc.

Products :

Activated Sludge Process

The activated sludge process is a process for treating sewage and industrial wastewaters using air and a biological floc composed of bacteria and protozoa.

In a sewage (or industrial wastewater) treatment plant, the activated sludge process is a biological process that can be used for one or several of the following purposes: oxidizing carbonaceous biological matter, oxidizing nitrogenous matter: mainly ammonium and nitrogen in biological matter, removing nutrients (nitrogen and phosphorus).

Products :

Attached Growth Process

Wastewater treatment processes in which the microorganisms and bacteria treating the wastes are attached to the media in the reactor. The wastes being treated flow over the media. Trickling filters and rotating biological contactors are attached growth reactors. These reactors can be used for BOD removal, nitrification, and denitrification.

Products :

Ion Exchange

Ion exchange is a resin based process, the inner bids of resin carry either positive or negative ion which can be exchanged with the ion of incoming water. The dissolved salt or solids comprising of positive or negative ions are passed through cation and anion resins to achieve desired results.
