BASIIA CONTRCTING
Engineered and Packaged Equipment
Brackish Water RO Systems
We build the complete Brackish Water Reverse Osmosis systems, as well as stock all major components for your maintenance needs. Controls, replacement cartridge filters, high pressure pumps and membrane elements. Reverse Osmosis (RO) technology, also known as hyper filtration, is used in every one of our stock and custom-made reverse osmosis water treatment systems to purify water by removing salts, contaminants and other impurities. Our full line of Brackish Water Reverse Osmosis Systems are available with a wide range of capacities (up to 20 thousand cubic meter per day) and TDS (up to five thousand parts per million total dissolved solids). In this way our systems set the standards in the water treatment industry. Our knowledgeable engineers and staff are always on hand to help and answer any questions or concerns you may have. We design each of our systems to be plug-and play, with all membranes, pumps, controls, manuals, filters, operating, and piping installed and ready to go.
Brackish Water RO units are used all over the world in many regions where clean potable water is scarce. It is ideal for food and beverage industries, potable drinking water, hospitals, agriculture, hotels & resorts, water bottling & ice making, pharmaceuticals and more. No matter your water application needs, Pure Aqua, Inc. can provide industry standard or custom designed brackish water RO machines.
RO Systems from Basiia deliver high performance at low life-cycle costs, saving on energy and increasing proficiency. Our pre-engineered systems are manufactured and built with high quality components designed specifically for water purification. Our systems arrive at your facility ready to run with all filters, membranes, pumps, piping, controls and operating manuals.
All of our RO packages are manufactured from components from USA, Europe and Japan.
Seawater RO Systems
From water-makers to industrial sized Seawater Purification, we offer a full range of systems. Our units are manufactured to eliminate a large amount of salts and other minerals from seawater using RO. Our equipment does the filtration by employing a high-pressure pump to salty water forcing it through semi-porous membranes denying salts and other organics from flowing through.
The membranes are only tasked to remove dissolved solids while dividing the feed water into purified water and rejected concentrated salts. The salts and other organics are thrown into the brine stream then flushed into a drain. At the end we have purified water that has 99% less dissolved salts. These sea water RO systems have the power to purify extremely high TDS water.
Seawater RO systems are usable anywhere from yachts to municipalities. It’s important to choose the correct materials of construction to handle seawater (which is highly corrosive). Basiia uses materials such as Duplex SS 2205, SS 2207 or Monel, and SS 904 to guarantee a longer operating life and less maintenance.
Basiia has extensive experience desalting seawater all around the world. Our engineers consult for other manufacturers of desalination equipment.

Nanofiltration
The fundamental principle of Nanofiltration membrane's technology is the use of pressure to separate soluble ions from water through a semi permeable membrane. The membrane, operates under a different hydraulic profile which is also known cross flow filtration, unlike a dead end filter.
Most Nanofiltration membranes are composite materials supported by polymer substrate and manufactured in a spiral design as opposed to a flat sheet or tube geometry. The predominant model used today for industrial applications is the spiral configuration.
Nanofiltration (NF), in water treatment, “bridges” a gap between UF and RO membranes. It is sometimes referred to as a loose or lower rejecting RO membrane. It could also be called a tight UF, as NF membrane pore size ranges from .01 to a little less than .001. Generally, an NF membrane system lets more salt pass than an RO membrane. In addition, an NF membrane element will produce the same quantity of product at 50 to 70% the applied pressure as an RO water treatment system.
There are applications where a 75% rate of salt rejection is preferable to 95 to 99%, especially when it is achieved using only half of the energy. Unlike with RO membrane elements, the NF offerings of the major membrane manufacturers are quite different in performance from company to company. With RO membrane elements, any model with less than 99.5% sodium chloride rejection, especially with seawater membranes, is considered inferior. In the case of NF, there is a “place” for any membrane with a NaCl rejection rate of 40%, or more. Nanofiltration has also been called a “softening” membrane as while its salt rejection may be 80% or less, hardness rejection will often remain well over 90%.
Like RO, and unlike UF, a Nanofiltration Systems will recover a percentage of the feed water. Most all NF membranes are of a spiral wound configuration.
Other applications of nanofiltration are:
• The removal of heavy metals from wastewater
• The removal of pesticides from groundwater
• Wastewater recycling in laundry facilities
• Water softening
• Nitrate removal
