Residential Rainwater Filter Collector

The rainwater coming from the roof through the down pipe is drawn through the vertically placed stainless steel filter insert by adhesion forces. It is then led through the outlet to the rainwater storage tank.

Because of the German patented unique construction, the dirt particles are rinsed directly into the drain with the remaining rainwater. More than 90% of the water passing through the filter collector is filtered and collected by this principle.

METHOD OF MAINTENANCE 


Filter Collector Maintenance


Minimal maintenance of the FS/GRS filter collector is required. The internal filter mesh is a vertical type of filter, therefore very little debris willow remain trapped on the mesh surface. This is enhanced further by the self cleaning properties which washes away all the remaining debris on the filter mesh with the next heavy rainfall. However, over a period time, depending on the roofing material and area of collection, a thin coating forms on the filter element. This has little effect on the water flow but it is recommended to maintain the filter twice a year to maintain the rainwater collection efficiency.

Filter Mesh Maintenance Method  


1. To take out the filter mesh. First, remove the filter collector outlet (4) pipe connection
2. Slide up the upper housing at the down pipe by approximately 10cm.
3. Lift out the filter casing (2) from the lower pipe. Take out the filter mesh and clean it using garden house, High pressure cleaner or sponge. Do not brush it with rough material as it will damage the strainer.
4. Install back to the down pipe. The unit can be use straight away after cleaning.

Rain Water Harvesting

Rainwater harvesting (also called roofwater harvesting) involves the collecttion, storage and distribution of rainwater from the roof, for use inside and outside the home or business.

Nowadays, when mains or reticulated water supplies are available to communities, many people choose to use rainwater that is collected from the roof and stored in tanks or other vessels to supply their water requirements. Rainwater is an ideal source for our water requirements and momentum behind rain harvesting is building.

With the latest initiative by the Malaysian Government in creating a sustainable environment for our future generations, the Malaysian Green Building Index was launched. This is the latest initiative by PAM and ACEM with the objective of leading the property industry to be more environmental friendly .

Myhomepalm Integrated is proud to be a provider of the service to our environment in Rain Water Harvesting. Our target is to harvest 1.2 million cubic meters of water by the year 2011. Pairing up with Rain Harvesting Aiustralia, GE Water & Process Technologies and Pentair Water, we have the products and expertise to meet our clients objectives.

Cooling Tower Treatment

Cooling tower water requires extensive treatment. During Cooling Tower water treatment, three main factors must be controlled.

• Corrosion of pipes and heat exchanger units.
• Scaling in pipes and (mainly) in heat exchangers.
• Microbial growth (bacteria, algae).
These three aspects cannot be viewed separately.

Conventional treatment techniques are mainly applications of chemical biocides, corrosion inhibitors and scale inhibitors. Ozone is a reliable alternative that controls the above-mentioned factors sufficiently.

Benefits of Ozone:

• Safe and easy in use.
• Low maintenance costs.
• Ozone is produced on-site and requires no storage of dangerous chemicals.
• Ozone requires no additional disinfectants.
• Micro-organism cannot get resistant to ozone after prolonged use of ozone.
• High efficiency as disinfectant.
• Very effective in removing bio films.
• Ozone is effective in a wide pH range.
• Makes the water crystal clear, eliminating all turbidity
• Dissolves the scale and inhibits further scaling, hence improving heat transfer and further saving on chemicals and pollution.
• Reduced Chemical Usage – Chlorine can substitute for several chemicals in a cooling tower treatment package,  reducing and possibly eliminating the use of such chemicals.
• Increases dramatically Heat Transfer Efficiency.

Ultra Filtration / Ultrafiltration / UF

Ultra filtration or UF is a pressure driven membrane separation process that separates particulate matter from soluble components in the carrier fluid (such as water). Ultra filtration has larger pores than nano filtration and reverse osmosis. Ultra filtration is a low pressure membrane process used to separate high molecular weight compounds from a feed stream.

Typically, ultra filtration will remove high molecular-weight substances, colloidal materials, organic and inorganic polymeric molecules Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed. Because only high-molecular weight species are removed, the osmotic pressure differential across the membrane surface is negligible.

Ultra filtration (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, end toxins and other pathogens to produce water with very high purity and low silt density. It serves as a pretreatment for surface water, seawater, and biologically treated municipal effluent before reverse osmosis and other membrane system

Ultra filtration, like reverse osmosis, is a cross-flow separation process. Here liquid stream to be treated (feed) flows tangentially along the membrane surface, thereby producing two streams. The stream of liquid that comes through the membrane is called permeate. The type and amount of species left in the permeate will depend on the characteristics of the membrane, the operating conditions, and the quality of feed. The other liquid stream is called concentrate and gets progressively concentrated in those species removed by the membrane. In cross-flow separation, therefore, the membrane itself does not act as a collector of ions, molecules, or colloids but merely as a barrier to these species.

Advantages:
• Low fouling membrane modules
• Excellent filtration performance
• High chemical resistance and temperature
• Tolerance for effective membrane cleaning
• High removal efficiency of bacteria and viruses
• Can be periodically back washed to improve
• Performance and extend operating life by removing the fouling layer

Sea Water Desalination

Oceans make up 97% of the world's supply of water. As demand for drinking water out strips limited fresh portable water supplies in an area. Desalting brackish and other saline waters may provide an attractive alternative or supplemental water supply.

Water, desalination of process of removing soluble salts from water to render it suitable for drinking, irrigation, or industrial uses. Desalination using seawater reverse osmosis (SWRO) membrane technology has become a viable option for the development of new regional water supplies.

Chemtronics Technologies supply of reliable seawater SWRO membrane desalination systems. Desalination projects range insize from small 2,000 cubic meter/day plants to 200,000 cubic meter/day.

In reverse osmosis desalination process, in which pressure is applied to saltwater to force it through a special membrane. Only pure water passes, leaving concentrated seawater behind. Reverse osmosis costs about half that amount of other desalination process.

Desalination :
Desalination refers to any of several process that remove excess salt and other minerals from water. It is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use in regions where the availability of fresh water is limited. Large scale desalination typically uses extremely large amounts of energy as well as specialized, expensive infrastructure, making it very costly compared to the use of fresh water from rivers or groundwater.
