Pure Aqua successfully manufactured and supplied a water filtration plant to a major hotel in Ghana to remove particulates, chlorine, organics, odor, hardness, and bacteria from well water. The water filtration plant is composed of multimedia, activated carbon, water softener, UV sterilizers, and cartridge filtration. The multi-media and activated carbon filters were selected from our MF-600 Series and both used 42” diameter FRP tanks. Both came with duplex arrangements, aquamatic valves and digital stagers along with interconnecting piping and wiring. The twin alternating water softener was selected from our SF-110F series, model # WSF48-1200-4-T. This twin alternating arrangement also came with aquamatic valves and digital stagers along with interconnecting piping and wiring. All were chosen to handle a flow rate of 120 GPM.
Since its startup, the water filtration plant has been running smoothly with minimal trouble-shooting. For satisfactory results, the plant utilized the following grades of media: Silica Sand, Anthracite, Activated Carbon, and Resin.
Silica Sand is a highly effective filter media because of its capability of holding back precipitates containing impurities. It is specifically graded for water filtration plants. Silica Sand’s fundamental characteristics include Filter sand size, hardness, and angularity. These characteristics guarantee proper filtration.
Anthracite is a black coal that has been recognized as a potential water treatment since the ancient times. When it is crushed, Anthracite makes an exceptional medium density filtration media. Its cracked shape allows some sediments to deeply penetrate into the bed. Anthracite is known to have extensive filter runs and fewer head loss. Also there is a reduction in backwash rates.
Activated Carbon is a black firm element that is similar to powdered and granular charcoal. It is consists of many pores with a very large surface area. Activated Carbon is known to effectively remove chlorine and some heavy metals bound to organic molecules. It has been found that activated carbon eliminates much more contaminants from water than regular carbon.
Resin is an insoluble support structure that usually comes in the form of small beads created from an organic polymer substrate. Resin’s structure is highly porous on the surface which are sites with easily trapped and released ions. They are widely used in processes such as separation, purification, and decontamination. Water softening and water purification are common examples of Resin.
Multi-media filters are manufactured to do away with suspended particles from water and service feed water with a turbidity of up to 20 NTU. In the filtration process, small particles descend down to tinnier and finer media levels. The cracks within these filters catch particles as low as 10 microns. The blocked larger particulates are caught on top of the filtration bed. At times multi-media filters are backwashed when there is an increase in pressure differential or when a timer begins. Activated carbon filtration systems use carbon draws attention to chemicals and impurities. Carbon has a little electro-positive charge added to it, so when water passes over the positively charged carbon surface, the contaminants negative ions are drawn toward the surface of the carbon granules. Activated carbon water filters remove impurities, odors, and colors from water.The two most significant factors affecting the efficiency of activated carbon filtration is the amount of carbon in the system and the amount of time the contaminants stay in contact with the carbon.
A Water Softener is used to remove minerals that cause hardness in water. Having hardness in water can cause negative outcomes such as clogged pipes, damaged boilers, and heat exchangers. Industrial, commercial and household water systems suffer from lime scale deposits as a result of hard water. Lime scale build-up can cause pipes to be clogged and reduces the efficiency of hot boilers, tanks, and laundry machines. Water softener systems improves the work and extends the life span of laundry machines, pipelines, solar heating systems, air conditioning units and many other water-based applications. The superior selective design of all above water equipment, made our water filtration plant robust, superior quality.

Pure Aqua, Inc. designs and manufactures water treatment systems in addition to water filtration plants. In March 2013, this water filtration plant was manufactured in the USA and delivered to Ghana to treat well water for use at a hotel. There are five steps to this water filtration plant. The steps are completed as follows with multimedia filtration, activated carbon filter, twin alternating water softeners, a UV disinfecting stage and finally, cartridge filtration.
