Working Principle:-

Pressurized water enters the filter Inlet (1) and travels through Fine Screen (2)where suspended particles are filtered. Clean water then exits the filter throughOutlet (12).As particles deposit on the screen, pressure drop across the screen increases, and is continuously sensed by Differential Pressure Indicator (10). When itreaches 0.5 bar, the Electric Control Unit (3) triggers the Solenoid Valve (11) toopen the Hydraulic Flushing Valve (4) and the upper, Hydraulic Motor Chamber(6) gets exposed to atmospheric pressure. With the lower chamber being at linepressure, water escapes from it to the upper chamber through the Dirt Collector(7). For this, water is sucked by Suction Nozzles (8) which dislodge & suck dirtdeposited on the inside surface of screen. As water passes through the HydraulicMotor (9), it gives the suction nozzle assembly rotary motion (like sprinklers inlawn irrigation). Simultaneously the Hydraulic Piston (5) raises the suctionassembly. With these two motions together, nozzles clean the whole periphery &height of the screen. The flush water flows through the dirt collector and out tothe flushing valve to atmosphere. After a preset time, the flushing valve closesand the cleaning cycle is complete. Dirt collector then settles down by gravity.

The entire cleaning cycle takes approximately 15 seconds.

Even during the back-flush cycle, filtering continues interrupted.

Benefits of Circulating Cooling Water On-line Filtration:

Following are various effects of TSS build up in circulating cooling water.

Many of them would apply to you:

Power consumption:

o chiller compressor power consumption goes up due to

fouling/scaling of condenser and cooling tower internals

o deposits in piping cause restriction to flow, causing more

pumping power for maintaining same flow

o reduced heat transfer efficiency in heat

exchangers/reactors/condensers necessitates increase in

cooling water flow rate, for evacuating same amount of heat,

consequently more pumping power.

Production loss:

o Reduced throughput in reactors/process-condensers, due to

slowed down cooling

o Downtime for removal of scale from condenser/heat

exchanger/reactor and Cooling Tower internals

Maintenance cost:

o Cost of manpower

o Cost of descaling chemicals

o Replacement of cooling tower fills & nozzles

o There are even instances of collapse of film fill assembly,

due to increased dead weight

Water consumption:

o CoC can be increased by keeping cooling water clean from

suspended solids

Water treatment chemicals' consumption:

o Goes up with rise in turbidity of cooling water, for maintaining

the chemicals' efficacy

Others:

Corrosion due to scaling and bacteria finding shelter between

scale & tube surface (known as under-deposit corrosion),

reducing life of tubes

o Every time chemical descaling is done, some parent material

is eaten away, reducing life of tubes

o Increased rate of erosion of pump seals & valve seats

o Erosion also happens due to continuous bombardment of

suspended matter carrying abrasive content

o Particles may also scratch away metal-oxide or other

protective films

o Suspended matter provides surface for microbial growth, which

is carried with humid & hot discharge air. It can spread

contamination in neighborhood as heavy air descends--

causing health hazard (there have been casualties abroad

caused by this phenomenon called Legionella)

o Organic suspended matter causes growth of biofilm & slime

which also leads to corrosion and insulation of heat

exchange surfaces.

On-line Cooling Water Filter of innovative design is a small-in-cost,

big-in-benefits solution for these problems, already working in 17 states of

India.

In circulating cooling water : Induced air brings in with it suspended matter continuously and its concentration in circulating water keeps rising. Its deposits on condenser tubes/plates and cooling tower internals cause a rise in compressor power consumption. By keeping the heat transfer surfaces clean from suspended matter, the filter ensures that compressor power consumption doesn't go up. Kindly see the attached note and our current client list.  

In circulating chilled water : Corrosion products, scale, and algae deposit on heat transfer surfaces of cooling coil, reactor and affect the heat transfer efficiency. Chilled water flow has to be increased to get the temperatures required-raising the power consumption. Filtration also minimizes erosion by corrosion products, maintenance, water treatment chemicals consumption, and blowdown of costly chilled water.   

Israeli technology - Fully automatic, zero maintenance, negligible water consumption. Installations are already in 23 Indian States.  

We offer systems with pressure upto 120 bar, so as to obtain a higher recovery than with conventional spiral wound construction. Also, this construction works well with higher turbidity & biological impurities and is easier to maintain.

To treat RO reject. Better Steam to Evaporation Ratio with lesser maintenance/fouling/choking of tubes.

Custom engineered systems for generating hot water at a low cost. With COP of the order of 3, input energy (Power/fuel) required is only a fraction of the conventionally consumed energy. Systems can be offered for generating hot water up to 120deg C, a unique feature.

For keeping heat exchanger clean from scaling/fouling. Industrial chilling and air-conditioning are most of the time the biggest power guzzlers in process industry & centrally cooled buildings such as hotels, hospitals, malls, office buildings. And within, chillers consume the most. Chiller compressors would easily be consuming more than 1/3rd of the total in the plants/premises. This equipment keeps Chiller Efficiency at peak all along.

On-line automatic removal of scale from condenser : The scale that deposits on condenser tubes continuously causes a rise in compressor power consumption. The automatic Tube Cleaning System keeps the tube clean from scale and has a unique, pump-less design. Reduces power consumption, downtime & maintenance.

Some Features :

• Saves 10-25% Compressor Power
• Eliminates Need of Chemical & Manual Cleaning
• No Dip in Cooling Throughput During Cleaning
• Protects Condenser Life
• Common System for Multiple Chillers, Saving Initial Cost
• No Wearing Parts

We are offering automatic tube cleaning system (atcs). deposits occur on condensers of water cooled chillers, and other heat exchangers. These cause power loss, downtime, long-term wear & tear, maintenance cost--even capacity-loss. atcs keeps the condenser tubes clean automatically and on-line--without having to take the equipment out of service.

Takes care of scaling, biofouling, algae, corrosion without chemicals. Virtually nil downtime.

It improves efficiency in HVAC and saves energy by a minimum of 20% in Air-cooled condensers and 10% in Water-cooled condensers, average annualized. Kindly see attached Catalog. Total savings in power with the implementation of the above could be well above 25%. Besides, there will be a substantial reduction in downtime & maintenance. 

Further, we also bring you the following energy/water / environment-saving technologies

For energy saving and improvement in Indoor Air Quality in Air Handling Units. Contaminated air passing through the cooling coil deteriorates the indoor air quality. Condensation of moisture around the cooling coils leads to growth of bacteria, viruses and other forms of microbes, reducing the heat transfer efficiency & air flow in the AHU--thereby increasing the power consumption. Ultraviolet light penetrates cell walls of microbes, damaging their DNA structure so that they cannot grow, thus keeping cooling coil clean on continuous basis and saving power and protecting air quality.

• 10-15% Power Saving
• Destroys airborne microbes
• Improvement in IAQ (Indoor Air Quality)
• Enhanced Cooling Coil & HEPA Filter Life
• Reduced Maintenance & Downtime
• Minimizes physical cleaning, pollution caused by cleaning agents and water wastage, and associated costs.

Latest 5th generation technology which provides reduction of the order of 40% in energy consumption. Maintenance Free, designed with HQ bearings so the bearing maintenance is nil, modulation through an in-built controller hence no need of additional VFD, designed to withstand a highly corrosive environment.
