Maagan Filtration applications

Drinking water has different sources of origin depending on the natural access point. Ground water, surface water, sea water as well as pre-used water are all among the potential accessible sources. Any stream has to be treated before being used for drinking, as it may have physical and chemical contaminates such as sand, colloidal silt or microorganisms (i.e. algae, bacteria).

The performance of an RO system highly depends on the quality of the protection of the pre-filtration. This is due to the following facts: Efficient removal of suspended solids results in longer operating intervals between chemical cleaning of the RO membranes. Less chemical cleaning cycles means prolonged lifetime for the RO membranes and reduced operating costs. Efficient removal of suspended solids results in reduced fouling of the RO membranes and most importantly, extends dramatically, the overall water recovery.

Numerous industries depend highly on filtered fresh water and demand efficient, reliable and cost effective filter solutions for their water polishing processes and water reusage. Cartridge filters are commonly used in many industries. These however often require scheduled and unscheduled shutdowns for maintenance, as well as manual cleaning and replacement of screens, bags, cartridges, and membranes, resulting in thousands of dollars in maintenance costs.

More than 85% of contaminated suspended solids in water from cooling towers and in hot water loops, are smaller than 5 microns. These micron contaminates circulate through heat exchangers, chillers, and compressors, significantly reducing the system’s cooling ability.Even tiny scale fouling and particle formation reduces the heat transfer rate and increases the water pressure drop through the heat exchanger, condenser and pipes, resulting in an increase in energy costs.

The Sheaf Filter  saves water, demands  less maintenance and has enhanced filtration as compared with  older, ordinary sand filters or diatomaceous earth filters used at public swimming pools today. With an automatic self-rinsing back-wash system utilizing less than 1% of the water from the overall water cycle, the Sheaf Filter reduces water consumption, energy consumption, cuts daily labor cost – (time spent on  maintenance), reduces chlorine demand and improves water quality.

Continuous population growth, rising standards of living, industrialization and urbanization limit the availability of fresh water. Wastewater treatment and reusage is increasingly emphasized as a method of freshwater conservation and as a means of safeguarding the aquatic environment. The Sheaf Filter can improve the common tertiary treatment practiced today, by removing fine particles in the range of 1-10 µm. This enables a constant and reliable water source, and reduces the amount of water extracted from the environment. Water availability will be a major constraint in the agriculture industry in the coming decades, particularly in Asia and Africa. The Sheaf Filter is an ideal solution for increasing overall water productivity.
