A Major Company in Angola


In May 2013, Pure Aqua successfully manufactured and supplied commercial seawater reverse osmosis units to a major company in Angola. The units came complete with an advanced microprocessor control along with pretreatments consisting of multimedia filters and an antiscalant dosing system. The SW-5.6K-604 unit was designed to produce 5,600 GPD while the SW-3.0k-304 was designed to produce 3,000 GPD both at a maximum 42,000 PPM feed water TDS. The units were selected from our SWC Series. From its initial start-up, the units have been running smoothly with minimal trouble-shooting. As a result, the company has had a reliable and steady supply of fresh, purified water at a cost far less than shipping water to the site. Reverse Osmosis is a simple process that involves eliminating a numerous amount of salt and other minerals from water sources that are highly non-consumable. A high pressure pump is utilized to combat the osmotic pressure of a natural process called “Osmosis”. Osmosis naturally moves salt through a semi-permeable membrane from an area with low saline concentration to an area with high saline concentration. Its purpose is to achieve an equal amount of saline concentration on both sides. This is when reverse osmosis comes in to reverse this process. The process begins by passing seawater through several pre-filters to eliminate particles and solids from the water. From there the water continues on into a water softener tank which takes out the hardness so the membranes within the system won’t be subject to any damage. It then goes through the actual machine where it passes through semi-permeable membranes. At this stage, the membranes take out the particles that the pre-filters bypassed. The membranes only allow water to flow through while blocking salts, minerals, and other impurities from carrying on. This results in the emergence of purified, potable water on the permeate side while Salt, minerals, and other impurities are flushed down the drain from the concentrate side.
