U.V. System

• 1. Domestic UV Plants
  (Ranges from 10 LPH to 250 LPH)
• 2. Industrial UV Plants
  (Ranges from 250 LPH to 100000 LPH)
• 3. Commercial UV Plants
  (Ranges from 3000 LPH to 100000 LPH)

U.V. System Ultraviolet light deactivates the DNA of bacteria, viruses and other pathogens and destroys their ability to multiply and cause disease. Specifically, UV light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevents the DNA to reproduce.

TECHNOLOGY

For the past 100 years science has recognized the bactericidal effects of the ultraviolet area of the electromagnetic spectrum. The specific wavelengths responsible for this reaction are situated between 240 - 280 nanometers (referred to as nm) with a peak wavelength of 265 nm and are known as UV-C.

Ultraviolet units with the finest 316 Stainless Steel, Electro Polished internally as well as externally for years of corrosion free service. The system Allows water to come in contact with Ultra Violet rays having 30,000 micro watts second/cm2 UV dosage & 2537 Angstrom (254 nm) units wavelength. The silica quartz jacket provides 100% efficiency due to its pure crystal clear transparency as compared to the Teflon tubes.

ADVANTAGES

• More effective against viruses than chlorine - Chlorine is becoming less acceptable because of harmful by­products, handling problems, & risk of overdosing.
• Immediate treatment process, no need for holding tanks, & retention times, so footprint is small.
• Extremely economical due to low capital, operational & maintenance costs.
• No chemicals added to the water supply – resulting in no byproducts & no need for specialized storage requirements
• No change in taste, odor, pH, conductivity of water
• Automatic operation
• Simplicity and ease of maintenance, periodic cleaning, and annual lamp replacement, no moving parts to wear out
• Easy installation, only two water connections and a power connection
• Compatible with any water treatment processes, (i.e. RO, filtration, and softening).
• Sand Filter, Sand Filters, Sand Filter Manufacturer, Scale Blaster, Scale Master, Mumbai, India

Sand & Activated Carbon Filter

Activated Carbon Filter Filtration is the process of passing liquid containing suspended matter through a suitable porous material (filtering medium) to effectively remove the suspended impurities in the liquid. It is the final step in the solid removal process which includes coagulation, Flocculation and sedimentation.

Types of Filters

• Inline filtration – In this process coagulant chemicals are added just prior to the water entering the filtration unit.
• Conventional filtration – It is a process commonly employed in municipal and large water treatments. Here all the pretreatment steps are included
• Direct filtration - It is similar to conventional filtration except that the step of sedimentation is omitted.
• Materials used as filter media - Quartz sand, Silica sand, Anthracite.

Multimedia filter

Multimedia filter also called as mechanical filter is composed of deep-bed system with multi layers of media in the tank. The major media to be applied in the system of sand and anthracite. The lightest and coarsest material is located at the top layer of bed for the removal of the largest suspended particles, while the heaviest and finest one is located at the bottom layer of bed to remove smaller one present in the source water.

The sand usually acts as a form of chemical treatment that, when in contact with soluble iron in water, reduced the iron from the soluble form to an insoluble form that will precipitate out of solution. The anthracite then can filter both the precipitated iron out of the solution as well as other entrained particles that have entered the water source. The combination of anthracite and sand together can remove a majority of suspended particles greater than 10 microns in size. After treatment, the SDI (Silt Density Index) is reduced and the turbidity reaches less than 3 from 20. The systems require backwashing to remove the accumulated contamination of suspended particles and rinsed by down flow clean filtered water before use in order to extend bed life.

Multimedia Filtration is widely used in the water pre-treatment, which available with Automatic and/or manual operational features. The tank material fiber glass reinforced plastic and stainless steel & Mild steel.
