Advantages
|
1. |
Filtration Technology:
Sand layers are formed into the filter with different layers. The surface area is less as the dia of filter decides the surface area not the height of filters. |
Need big filter and rooms to accommodate them.
Waste space and room. |
Filtration technology is cartridge based and the cartridge is fixed length wise with V-shape winding. |
In 200mm dia and 600mm height we can have 7 sq meter filter surface area which is equivalent to 4000mm dia sand filter. |
|
Sand based Filtration can be efficient up to 40-60 microns. |
No uniformity in filtration. |
Cartridge based filter is having the efficiency of 20 micron. Reputed company makes the cartridge filter. So there is a uniform gradation |
That means water into pool will be clearer than sand filter. And uniformity in filtration. |
|
There are five to seven valves to be operated in the filter unit. |
Need operator and valve usually need maintenance. |
No valve or piping. |
No operator required and less maintenance. |
|
AS per ISI standards the flow rate is 15cum/h/m2 max |
Need bigger filters |
Comes under ISI standard for flow rates as low flow rate is required |
Follow ISI standards with increasing size. |
2. |
Power consumption:
Since the filter unit is far from the pool and there is one meter thick layer in sand filter the higher power and capacity pumps required. |
More electricity required and more expense. |
Cartridge thickness is 2-3mm and filter is near the swimming pool. so less power pumps required. |
1 hp motor pump can work for similar size pool as 5hp pump required in sand filter.
So more savings. |
3. |
Water Wastage:
There are three points, which waste the water daily.
Back wash of filter
Rinse the filter |
Around 4% of water and chlorine are wasted daily just to wash the filter. |
These filters are design to 0% wastage. Ten pools can be operated with the same quantity of water required in one no of pool with old technology. hence save water and reduce global warming. |
Saves 100% water and chemical consumption goes down up to 70%.
in comparison of sand filters. |
4. |
Need for balancing tank, filter room, skimmers or overflow grating plumbing pipes & valves, Nozzles, ladders, lights, chemical dozer etc. |
Need structure just to take water to filter and space for filter. |
Pipeless filters are small in size and near the pool. So no additional structures are required. |
So saves space and cost that is 30% cost saving in comparison of sand filter based filtration system. |
5. |
Water Leakage:
We need to put plumbing pipes, electrical conduits into the pool that leads to puncher into RCC wall and floor & after some time plumbing pipe may be damaged due to ageing or the earthquake or any other reason and possibility of leak even your pool is water proofed properly. |
In this system there are multiple chances of water leakage or seepage. |
There is no puncher into the walls and floor for any thing so there no need to take extra care for waterproofing.
No leakage is possible due to any mechanical or electrical items. |
Filter is mounted and no puncher in pool is required. So there is no chance of water leakage today or any time in future.
No concealed parts. |
6. |
In sand based filter the following consultants are required during the process of construction:
Pool Consultant
Plumbing consultant
Electrical Consultant |
So the warrantee and guarantee expired till the time of actual usage of swimming pool. |
Pipe less filters remove the need of any consultant as no provisions out let inlet or any structures needed. |
They can be installed within two days before actual usage of swimming pools. |
